As we move towards real-world deployment, you’ll have genuine ownership of your area, working alongside a highly technical team of physicists, engineers and software specialists on one of the hardest problems in AI infrastructure.\nJob Overview\nAs an Embedded Software Engineer at Salience Labs, you’ll be right at the centre of our photonics product development. This role spans low-level firmware, rapid prototyping, and systems integration, giving you the chance to influence everything from proof-of-concept devices to our commercial platforms. You’ll collaborate across hardware, photonics, and FPGA teams to ensure smooth, efficient embedded software development, right down to the register level and all the way up to application-facing tools.\nThis is a full-stack embedded role, where versatility and curiosity are just as important as technical depth. We’re looking for engineers who enjoy working close to the metal, but can just as easily contribute to user-facing tools and test infrastructure. You’ll be part of a small, fast-paced team where autonomy is encouraged and impact is tangible.\nWhat you’ll be doing\nDesign, implement, and document embedded software across a variety of project scales\n\nWork closely with hardware and FPGA teams to build robust embedded systems\n\nUse off-the-shelf development kits for rapid prototyping and system testing\n\nSelect, tailor, and integrate open-source applications and embedded frameworks\n\nCollaborate with the Systems Test team to support test automation and data capture\n\nDevelop internal tools and test benches for the photonics and hardware teams\n\nWhat we’re looking for\n4+ years of hands-on experience developing embedded software in C or C++\n\nProven ability to own software modules from design to delivery\n\nComfortable using Python and modern tooling (Git, Confluence, Jira)\n\nStrong problem-solver with clear analytical thinking and communication skills\n\nFlexible team player, able to switch between solo work and close collaboration\n\nEven better if you\nCan read schematics or interpret RTL, particularly helpful for supporting hardware teams\n\nHave experience developing for ARM-based embedded platforms\n\nKnow your way around I2C, SPI, PCIe, and embedded driver development\n\nUnderstand networking concepts\n\nAre comfortable becoming a domain expert in unfamiliar tools or technologies\n\nThis is a high-impact role for someone who thrives on building, testing, and iterating in real hardware environments. If you’re looking for a deeply technical role where you can have influence across the full product stack, and you like the sound of building the software brains of next-gen optical systems, then we’d love to hear from you.","description_format":"text","description_chars":2854,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Optical Communications","Optics & Photonic Components"],"lifecycle":[{"event":"open","at":"2026-11-13T19:17:24Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-13T08:07:55+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":26,"reasons":["conf:1","win:early"],"computed_at":"2026-11-13T21:09:05Z"},"pay":null,"html_url":"https://alion.io/job/salience-labs-embedded-software-engineer-2","json_url":"https://alion.io/job/salience-labs-embedded-software-engineer-2.json","meta":{"generated_at":"2026-11-13T21:09:05Z","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":42175,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":2029320},"rest":"https://alion.io/mcp/rest/get_company?id=2029320"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsalience-labs-embedded-software-engineer-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fsalience-labs-embedded-software-engineer-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fsalience-labs-embedded-software-engineer-2"},{"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/salience-labs-embedded-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsalience-labs-embedded-software-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4276937}},{"tool":"search_jobs","arguments":{"company":"saliencelabs.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4276937},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
