What we learn there becomes the foundation for a civilization-defining capability.\nWe’re a small, talent-dense team with high ownership, high velocity, and low ego. We care deeply, move fast, and are here to build something that outlasts us.\nTogether, we’ll redefine cyber-physical security for the AI age.\nWhat makes this role special?\nOne of the first 10 engineers shaping hardware systems pre-Series A.\nOwn firmware that leaves the lab and operates in some of the world’s highest-stakes environments.\nWork directly with the hardware lead across EE, firmware, and embedded systems.\nOperate in environments where hardware decisions have immediate consequences.\nPartner with RF, ML, and product teams to deliver integrated systems.\nDefine the trust boundary between hardware and software.\nWhat we’re looking for...\n3-6 years writing systems-level firmware for embedded targets with real depth, not glue code on top of HALs\nStrong command of C with the ability to adopt new systems languages (Rust, Zig, C++) when appropriate.\nProven background in red teaming, offensive security research, or adversarial testing targeting embedded systems and physical hardware.\nReasons about trust boundaries, failure modes, and adversarial inputs before they become vulnerabilities.\nThrived in an early-stage startup.\nComfortable operating without perfect specs or complete information.\nU.S. Person status required (may involve export-controlled data).\nBonus if you’ve...\nShipped firmware on microcontrollers and OS-based embedded systems.\nWritten firmware for systems with secure boot, verified OTA, or hardware-enforced trust boundaries\nDone RF/SDR-adjacent work or integrated wireless radios at the firmware layer\nMaintained embedded Linux systems (custom rootfs, systemd services, power management)\nHeld a security certification or contributed to a CVE, hardware CTF, or published security research.\nWhat you’ll do...\nOwn firmware across RTOS, embedded Linux, wireless radios, GPS, and custom embedded hardware.\nWrite and maintain system daemons and firmware modules with strict fault isolation\nOwn secure boot and verified firmware update pipelines end-to-end\nConduct adversarial review of firmware attack surfaces (e.g. USB, BLE, UART, OTA) and close what you find\nPartner with RF and ML teams on high-throughput signal capture and real-time processing pipelines.\nBuild and maintain hardware validation tooling; reduce bring-up friction on every successive board spin.\nHow we select...\nShort application\n20-minute intro call\nTechnical deep-dive\nPractical problem discussion\nReferences and offer\nFinal facts.\nBase salary up to $220,000 depending on qualifications, experience, and impact. Total compensation includes equity, premium insurance, 401(k), flexible PTO, and other individual benefits.\nYou’ll join us on-site at our HQ in New York City with occasional domestic and global deployments.\nApply. Make history. Build humanity’s defense against machines.","description_format":"text","description_chars":3751,"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"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-11T21:56:57Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":137500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.238,"p_room":0.28,"age_days":111,"expected_fill_days":23,"reasons":["conf:10","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":{"stated_usd_annual":220000,"is_top_pay":true},"html_url":"https://alion.io/job/sweep360-firmware-engineer","json_url":"https://alion.io/job/sweep360-firmware-engineer.json","meta":{"generated_at":"2026-10-25T07:03:58Z","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":9923,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":687189},"rest":"https://alion.io/mcp/rest/get_company?id=687189"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsweep360-firmware-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%2Fsweep360-firmware-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%2Fsweep360-firmware-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/sweep360-firmware-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsweep360-firmware-engineer"}]}
