Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.\nOur work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.\nAbout the Role\nAs Kernel Software Engineer, you own the low-level software platform that sits between our hardware and the flight application on our ground control stations. You work across the Linux kernel, board support and a custom Android build, so that every control, display and data link works reliably in the field. You are the bridge between our hardware and application teams, taking a new product line from board bring-up to mass production.\nResponsibilities\nBring up, configure and maintain the Linux kernel on our hardware, including device tree, drivers and security patches.\n\nCustomize and maintain our Android build, covering system services, permissions, boot sequence and OTA updates.\n\nIntegrate controls, display, touch, battery and radio modules, and expose them cleanly to the application layer.\n\nEnsure robust, low-latency SBUS and MAVLink data flows between the controller, the radio and the drone.\n\nDebug hardware and software issues alongside electronics and mechanical engineers, using oscilloscopes, logic analyzers and UART/JTAG.\n\nDefine flashing, provisioning, factory test and release procedures with the production team.\n\nWork with QGroundControl engineers and QA to validate system behavior on real hardware.\n\nJoin field tests and flight sessions to validate your work in real conditions.\n\nCandidate Requirements\nMaster’s degree in Embedded Systems, Software Engineering, Electronics or a related field.\n\n3+ years of experience in embedded software development.\n\nStrong command of the Linux kernel (configuration, device tree, drivers, debugging) and of C; C++ is a plus.\n\nHands-on background customizing AOSP, from HALs and system services to the build system.\n\nComfortable at the hardware boundary: UART, SPI, I2C, GPIO, USB, display and touch controllers.\n\nExposure to drones or robotics, including MAVLink or PX4/ArduPilot, is a plus.\n\nHands-on, autonomous and pragmatic, with curiosity about hardware and the ability to learn quickly.\n\nProfessional English for technical documentation and international collaboration.\n\nWe look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.","description_format":"text","description_chars":2732,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2025-10-06T17:01:54Z"},{"event":"open","at":"2026-09-26T01:36:16Z"},{"event":"close","at":"2026-10-08T13:33:07Z"},{"event":"reopen","at":"2026-10-11T21:29:35Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.231,"p_room":0.28,"age_days":375,"expected_fill_days":74,"reasons":["conf:1","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-ai-software-engineer","json_url":"https://alion.io/job/harmattan-ai-software-engineer.json","meta":{"generated_at":"2026-10-17T15:54:42Z","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":21567,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":8839},"rest":"https://alion.io/mcp/rest/get_company?id=8839"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fharmattan-ai-software-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%2Fharmattan-ai-software-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%2Fharmattan-ai-software-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/harmattan-ai-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-ai-software-engineer"}]}
