We combine first-principles thinking with cutting-edge technology to build a radically better energy system.\nWe've raised over $200M from top-tier investors including Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, 20VC, Hummingbird and Collaborative Fund, alongside strategic angels including Nico Rosberg and GPs behind Meta, Revolut, Spotify and Uber.\nWe're building a fully integrated energy company: developing our own solar, batteries and other generation projects, building our own hardware, improving and developing grid infrastructure, trading power in real time, using AI across the business, and installing distributed energy in homes. By selling directly to consumers we cut out the middleman, lower costs and pass the savings on to our customers.\nWe're looking for an Embedded Software Engineer in the US to help design, build and scale the connected hardware powering our fleet of distributed energy devices. This hands-on remote role spans embedded systems, networking, device security and fleet connectivity from prototype through to deployment: resilient connectivity, secure provisioning and robust telemetry across a growing fleet of devices. You'll shape how our devices connect, communicate and evolve securely at scale, working closely with firmware, hardware and backend teams to deliver production-ready systems.\nResponsibilities\nDevelop and maintain connectivity across Ethernet, Wi-Fi, Thread, Zigbee and BLE\nBuild and optimise secure, reliable device messaging using protocols such as MQTT, CoAP, HTTP or WebSockets, and support device time synchronisation (NTP/PTP)\nContribute to secure boot flows, key and certificate provisioning, and hardware-backed device identity using TPMs or secure elements\nBuild and maintain signed firmware update pipelines, including OTA update and rollback, and support security best practices across the device lifecycle\nIntegrate devices with cloud IoT platforms and backend services, and improve telemetry, health monitoring and observability for deployed devices\nSupport reliable field operation, debugging fleet issues and improving resilience\nSupport testing and validation for safety, EMC, radio and related requirements, and help prepare test plans and certification artefacts\nWork closely with firmware, hardware, power electronics, mechanical and software teams, contributing to design reviews, documentation and interface specifications\nRequirements\nBachelor's degree in Electrical Engineering, Computer Engineering, Computer Science or equivalent practical experience\n2+ years building connected embedded products, or strong relevant industry/project experience\nGood proficiency in C/C++ for embedded systems, with experience of RTOS environments such as Zephyr or FreeRTOS\nExperience with Python for testing, tooling or automation\nSolid understanding of device connectivity and networking fundamentals, including IP networking and common transport/application protocols\nExperience implementing or supporting secure device communications using TLS, certificates or device provisioning workflows\nFamiliarity with firmware update systems, bootloaders or CI/CD workflows for embedded software\nPractical debugging experience using lab and software tools such as logic analysers, protocol analysers, network sniffers or observability platforms\nStrong problem-solving skills and the ability to work across hardware and software boundaries\nBonus: low-power wireless (Thread, Zigbee, BLE); cloud IoT services on AWS, Azure or GCP; secure boot, TPMs, secure elements or hardware attestation; EMC/RF testing, antenna bring-up or factory test; awareness of standards such as IEC 62443, ETSI EN 303 645, ISO 27001 or GDPR; industrial, energy or other distributed device deployments\nBenefits\nCompetitive salary and eligibility for equity\nBiannual bonus scheme\nFully expensed tech to match your needs\nPrivate health insurance\nBreakfast and dinner allowance for office-based employees\nAs we hire globally, benefits vary by location.","description_format":"text","description_chars":4089,"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":["Equity","Health insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Solar Energy","Wind Energy"],"lifecycle":[{"event":"open","at":"2026-07-24T00:00:00Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.454,"p_room":0.45,"age_days":53,"expected_fill_days":27,"reasons":["conf:0","stale_co","velocity","win:tail"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/fuse-energy-embedded-software-engineer-remote","json_url":"https://alion.io/job/fuse-energy-embedded-software-engineer-remote.json","meta":{"generated_at":"2026-10-16T21:45:52Z","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":2946,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":3017},"rest":"https://alion.io/mcp/rest/get_company?id=3017"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffuse-energy-embedded-software-engineer-remote"},{"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%2Ffuse-energy-embedded-software-engineer-remote"},{"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%2Ffuse-energy-embedded-software-engineer-remote"},{"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/fuse-energy-embedded-software-engineer-remote\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffuse-energy-embedded-software-engineer-remote"}]}
