We seek highly motivated people who proactively and obsessively strive to solve novel problems all the way to product launch and beyond, fundamentally changing the way we build, maintain and monitor physical structures.\n\nWhat we doWe build retrofittable sensors that measure the clamping force inside a bolted joint. Using magnetostrictive sensing, each sensor reads the stress in a standard steel bolt without touching it and without modifying the joint, then reports over LoRaWAN to a cloud platform where trend analysis reveals developing risk long before an inspection would. It clips on in under a minute and delivers structural integrity data for up to twenty years.\nBolted joints hold up critical infrastructure everywhere: wind energy, bridges and civil infrastructure, rail, tunnels and mining, and heavy process industry. A single wind turbine alone holds over a thousand bolts whose tension is checked by hand, if at all, and loss of preload is one of the main drivers of structural failure. The same sensor addresses all of them.\n\nWhy nowWith ex-McKinsey leadership, we have developed and patented industry-leading technology over the last 7 years and recently reached a technical breakthrough, enabling an oversubscribed seed round with top-tier investors (to be announced), selection as one of Sweden's top 33 startups, a place in NATO's DIANA program chosen out of 3400 startups, and a Letter of Intent to purchase 47 000 sensors.\nVision: Become the leading structural integrity data provider globally\nTarget: Volume production and distribution of retrofitted sensors, providing 20 years of structural integrity data\nCulture: Truth seeking, high agency, pragmatic, entrepreneurial and hypothesis driven\nSeeking: Exceptional drive, intelligence and integrity. Lead rather than follow.\n\n___\n\nThe RoleYou will build the Safety Bolt firmware stack from the ground up: architecting, implementing, and owning the embedded software for our wireless sensor node. You will work on a modern low-power embedded platform with wireless connectivity, including LoRaWAN and BLE. You will implement signal processing algorithms developed in collaboration with our data science team, and progressively take ownership of algorithm development as the product matures. This is a senior, architecture-level role: you set the direction, not just write the code.\n\nWhat you will doDesign and implement the embedded firmware architecture for the Safety Bolt sensor node, from prototype to production-ready\n\nImplement on-device DFT-based signal processing and take increasing ownership of algorithm tuning and development\n\nWork at the hardware/software boundary: bring up new hardware revisions, debug analog signals, collaborate closely with the EE on measurement quality\n\nBuild firmware with a product mindset from day one: structured, testable, and on a path to wireless certification (CE/FCC)\n\nContribute to system-level decisions across the full sensor stack\n\nMust haveStrong embedded C/C++ development for microcontrollers, bare-metal and/or RTOS\n\nExperience architecting embedded systems from the ground up; you have owned a firmware stack end-to-end\n\nHands-on with wireless protocols: BLE and/or LoRa/LoRaWAN\n\nComfortable at the hardware boundary: oscilloscopes, logic analyzers, analog signal debugging\n\nExperience developing firmware intended for commercial products and certifications, not only prototypes\n\nAbility to work independently with high ownership and low need for hand-holding\n\nNice to haveExperience with Zephyr RTOS or similar embedded operating systems\n\nBackground in DSP or signal processing implementation on embedded targets\n\nExperience with low-power embedded design for battery-operated IoT devices\n\nExposure to wireless certification processes (CE, RED, FCC)\n\nExperience implementing ML inference or statistical models on embedded hardware\n\nBackground from industrial sensors, measurement equipment, or precision IoT\n\nEducationMSc in Embedded Systems, Electrical Engineering, Computer Engineering, or equivalent. A BSc will be considered given strong, documented experience.\n\nExperience level5+ years of embedded systems development, with a clear track record of owning and delivering complete firmware stacks. We are looking for someone who has already made the architecture decisions, not someone learning to.","description_format":"text","description_chars":4608,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical & Electronic Engineering","Transportation & Logistics","Industrial IoT (IIoT)","Ride Hailing"],"lifecycle":[{"event":"open","at":"2026-10-11T21:14:16Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":0.6,"p_active":0.328,"p_room":0.45,"age_days":42,"expected_fill_days":24,"reasons":["seen:42","win:tail"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/safety-bolt-senior-embedded-systems-engineer","json_url":"https://alion.io/job/safety-bolt-senior-embedded-systems-engineer.json","meta":{"generated_at":"2026-10-13T05:59:39Z","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":9303,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":2654305},"rest":"https://alion.io/mcp/rest/get_company?id=2654305"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsafety-bolt-senior-embedded-systems-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%2Fsafety-bolt-senior-embedded-systems-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%2Fsafety-bolt-senior-embedded-systems-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/safety-bolt-senior-embedded-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsafety-bolt-senior-embedded-systems-engineer"}]}
