We design our own wearable hardware, deploy it alongside craft workers, and transform a shift's footage into a next-morning report. Our internal team and purpose-built models label the data overnight and deliver actionable insights to superintendents by 5 AM.\nWe are accelerating the speed, efficiency, and predictability of construction, especially for complex, mission-critical infrastructure projects, including data centers, LNG facilities, sports stadiums, hospitals, and other large-scale developments, by training AI models on egocentric construction footage and labor productivity data. We are built with a pro-worker philosophy at our core: we believe technology should empower the workforce, not replace it. We're working to give craft workers and project leaders better visibility into what's happening on-site, while creating a system where the reality of construction and the chaos of each day is finally available to the people running the project.\nIronsite is deployed across several of the largest active construction projects in the country. To date, we've captured more than 100,000 hours of construction footage across seven states, now process thousands of hours of site activity every day, and maintain a worker opt-out rate below two percent. This is enabled by a workforce-first architecture that anonymizes devices, captures no audio, and never releases raw video.\nIronsite is backed by leading investors (8VC, South Park Commons, Saga Ventures) and prominent operators across technology and construction, including Eric Schmidt, Jeff Dean, Jeff Rothschild, Mark Leslie, Scott Wu, Eric Glyman, Karim Atiyeh, Russell Kaplan, and others, alongside over a dozen construction industry operators who have joined us as partners in building this.\nLonger term, we believe Ironsite is the foundation for what construction becomes in the next decade. We think the systems we're building are the operating system for how the physical world gets built, and will unlock a fundamentally different way of respect for our workforce. One where craft workers are more valued, more visible, and better paid for the skill they bring, and where the industry finally has the intelligence layer that makes autonomous construction possible. Both futures start with the same foundation.\nThe Role\nWe're hiring a Senior Electronics Engineer to own the electrical architecture of Ironsite's wearable hardware.\nThis is a foundational role on the hardware team. You'll design and validate the PCBs, power systems, and multi-sensor integration that make Ironsite's devices work reliably on active jobsites, on ruggedized wearables operating in some of the harshest environments in American industry. Power efficiency, sensor performance, thermal behavior, and integration density are all electrical engineering problems in this seat. If the hardware architecture doesn't hold up, nothing else does.\nYou'll work directly with mechanical engineering, firmware engineering, manufacturing, and industrial design across the full product lifecycle, from initial concept through volume production. You'll own multi-layer PCB design, high-speed signal integrity, power management, and multi-sensor integration for optical, audio, wireless, IMU, and environmental subsystems. This is one of the most technically demanding seats in the company, and one of the highest-leverage.\nWhat You'll Do\nElectrical architecture and PCB design.\nDesign multi-layer PCBs from concept through DFM, including schematic capture, layout, and signal integrity analysis for high-speed and mixed-signal designs.\nOwn end-to-end electrical architecture for wearable hardware programs, from feasibility through hardware bring-up and production release.\nOptimize designs for size, power efficiency, thermal performance, and integration density, with the constraints that matter in a wearable running an 8-12 hour shift.\nDrive component selection, sourcing collaboration with supply chain, and design tradeoffs across cost, performance, and manufacturability.\nPower systems and battery integration.\nDesign and validate power delivery systems, including battery management, charging, protection circuits, and low-power modes.\nOwn the electrical side of battery selection and integration, and partner with mechanical engineering on packaging and thermal design.\nBuild the power architecture that supports continuous recording, encoding, wireless upload, and on-device inference across a full shift without failure.\nMulti-sensor integration.\nIntegrate optical (imaging), audio (where relevant), wireless (BLE, Wi-Fi, LTE), IMU, and environmental sensors into a cohesive hardware platform.\nOwn high-speed interfaces (MIPI CSI, USB, PCIe, and similar) and the signal integrity work that makes them reliable at scale.\nPartner with firmware engineering on sensor bring-up, driver validation, and system-level tuning.\nBring-up, validation, and test.\nLead hardware bring-up on new PCB revisions, from first power-on through validated production release.\nDesign and execute characterization and validation test plans across environmental conditions (temperature, humidity, vibration, EMI/EMC).\nOwn manufacturing test coverage, including ICT, functional test, and factory calibration in partnership with manufacturing engineering.\nCross-functional partnership.\nCollaborate with mechanical, firmware, manufacturing, and industrial design across the full product lifecycle, from concept through DFM, DFT, and volume production.\nRepresent electrical engineering in design reviews, and drive design decisions that balance electrical, mechanical, firmware, and manufacturing constraints.\nSupport contract manufacturers with technical guidance, design updates, and issue resolution during production ramp.\nTechnical Challenges You'll Solve\nFitting more capability into a smaller, lighter wearable. Every new generation of Ironsite hardware needs to be more capable while getting smaller and lighter, because wearability drives adoption. You'll make the density, power, and thermal tradeoffs that let us pack more into less without compromising performance or reliability.\nPowering continuous capture through a full shift. All-day recording on a single charge requires power engineering discipline at every layer, from component selection through architecture. Every microamp matters, and every electrical decision has power implications that ripple through the product experience.\nHigh-speed integration in a small form factor. MIPI CSI for the camera, wireless stacks, high-speed data paths for on-device processing, all in a device that has to be small enough to embed in a hardhat and rugged enough to survive a jobsite. Signal integrity in that context is genuinely hard.\nDesign for real-world reliability. IP67-rated devices operating in dust, moisture, temperature extremes, impact, and vibration for years. Electrical robustness at that level is a discipline, not a feature. You'll design the systems that keep the fleet healthy at scale.\nDesign for volume manufacturing. Every design decision has manufacturability and cost implications that compound at scale. You'll design with production in mind from day one, and partner with manufacturing engineering to drive the DFM iterations that make ramp smooth rather than painful.\nWhat We're Looking For\nRequired\n6+ years of hands-on experience shipping electrical designs on production hardware, with at least one full product lifecycle delivered in wearables, cameras, consumer electronics, or ruggedized hardware at real volume.\nDeep expertise in multi-layer PCB design, schematic capture, and layout for mixed-signal and high-speed designs.\nStrong experience with power system design, including battery management, charging, protection, and low-power techniques for wearable or portable devices.\nHands-on experience integrating optical imaging systems (MIPI CSI or similar), wireless connectivity (BLE, Wi-Fi, LTE), IMU, and environmental sensors into cohesive hardware platforms.\nExperience with high-speed signal integrity analysis and design for reliable operation at production yields.\nComfort reading schematics, datasheets, and using standard hardware lab tools (oscilloscope, logic analyzer, network analyzer, thermal camera, protocol analyzers) to debug hardware and hardware-software integration issues.\nSystems thinking across the full hardware stack. From silicon and PCB through mechanical integration and firmware, you understand how electrical decisions propagate throughout the product.\nExperience working directly with contract manufacturers on hardware bring-up, DFM, DFT, and production ramp.\nA background in Electrical Engineering, Computer Engineering, or a related field, or the equivalent experience.\nStrongly preferred\nExperience shipping wearable products at consumer volumes (Fitbit, Oura, Whoop, GoPro, Bose, Apple, Meta, Snap, or similar).\nExperience with camera sensor integration and imaging system design, including selection, integration, and characterization of image sensors.\nExperience designing for ruggedized industrial or outdoor environments (IP-rated devices, temperature extremes, EMI/EMC compliance).\nExperience with battery cell selection, custom battery pack design, and battery safety certification.\nAbility to generate clear and concise technical documentation for internal teams, contract manufacturers, and executive stakeholders.\nNice to have\nFamiliarity with contract manufacturers in Taiwan, mainland China, or Southeast Asia.\nExperience with FCC, CE, or other regulatory certification processes for wearable or wireless devices.\nExperience with prior electrical engineering leadership at a hardware startup that scaled from early volumes to full production.\nMandarin or Vietnamese language proficiency.\nFamiliarity with mechanical CAD tools (SolidWorks, Fusion 360) for cross-functional collaboration.\nWhat Success Looks Like\nFirst 90 days. You know our hardware platform cold, including the electrical architecture, the sensor stack, the power system, and the manufacturing test infrastructure. You've contributed meaningful design improvements to a current or upcoming hardware revision.\nFirst 6 months. You've owned a major electrical engineering initiative end to end, whether it's a next-generation hardware bring-up, a power architecture redesign, or a sensor integration that materially improves what our devices can do. Your work is shaping what ships next.\nFirst 12 months. You're the internal authority on electrical engineering at Ironsite. Our hardware is more capable, more reliable, and more manufacturable because of you. When we scale from thousands of devices to hundreds of thousands, we do it because the electrical architecture you designed holds up.\nLocation, Compensation, & Perks\nSan Francisco Bay Area (on-site)\nBase salary: $225k-$300k per year, commensurate with experience\nSignificant early-stage equity\nFull benefits including health, dental, vision, and 401(k) with 6% match\nDaily catered breakfast and lunch\nOffice in San Francisco, next to Oracle Park and the Caltrain\nFinal compensation is determined by experience, location, and level.\nWhy This Role\nEvery category-defining hardware company has an electronics engineer who was the reason the hardware actually worked. Not because they had the cleverest circuit, but because they cared obsessively about the last 2% of power efficiency, the reliability edge cases at scale, and the manufacturing details that separate a product that ships from a product that gets returned.\nIronsite is at that moment. We have the product, the customers, the funding, the manufacturing partnerships, and a hardware roadmap that scales into hundreds of thousands of units. What we need is the electrical engineer who is going to design the hardware architecture that lets us get there.\nIf you've spent your career shipping electrical designs on wearables or ruggedized hardware at volume, and you're read...","description_format":"text","description_chars":12154,"description_truncated":true,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Vietnamese","level":"Advanced (C1)","optional":true}]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-14T12:30:37Z"}],"visa":[],"liveness":{"score":18,"band":"cold","label":"Long shot","p_open":1,"p_active":0.502,"p_room":0.35,"age_days":54,"expected_fill_days":23,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-14T23:55:10Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/ironsite-sr-electronics-engineer","json_url":"https://alion.io/job/ironsite-sr-electronics-engineer.json","meta":{"generated_at":"2026-10-14T23:55:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":332,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4409697},"rest":"https://alion.io/mcp/rest/get_company?id=4409697"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fironsite-sr-electronics-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fironsite-sr-electronics-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fironsite-sr-electronics-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/ironsite-sr-electronics-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fironsite-sr-electronics-engineer"}]}
