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 an Embedded Software Engineer on Harmattan AI’s GCS (Ground Control System) module, you’ll develop the firmware and low-level software that powers our next-generation handheld UAV controllers. This includes real-time handling of inputs (joysticks, buttons, touchscreens), communication with the UAV, power management, and overall system responsiveness. Your code will bring to life a reliable, intuitive, and mission-ready operator experience.\nResponsibilities\nDevelop embedded firmware for custom handheld ground stations, integrating displays, input devices, wireless modules, and battery systems.\n\nImplement the interface with the radio link.\n\nOptimize system performance for responsiveness, power efficiency, and thermal constraints.\n\nCollaborate closely with electrical and mechanical engineers to ensure seamless hardware-software integration.\n\nConduct field validation and debugging under realistic mission scenarios.\n\nWrite clean, maintainable, and production-ready code with a focus on long-term system stability.\n\nParticipate in architectural decisions to scale the firmware platform as the GCS product line evolves.\n\nCandidate Requirements\nEducation: Master’s in Embedded Systems, Computer Engineering, or equivalent.\n\nStrong experience in embedded C/C++ and real-time firmware development.\n\nProficient with CPU, MCU, (experience with ARM is a strong plus), hardware abstraction layers, and protocols like SPI, I2C, UART.\n\nExperience with embedded Linux\n\nFamiliarity with wireless comms integration (e.g., LoRa, Wi-Fi, LTE, custom RF) is a plus.\n\nBonus: Experience building handheld or ruggedized control systems in defense, aerospace, or robotics.\n\nProblem-Solving: Ability to work autonomously and solve complex technical challenges.\n\nCommunication & Influence: Excellent written and verbal communication, capable of leading diverse principals - from junior members to senior executives.\n\nCommitment: 100% dedication to Harmattan AI’s mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence.\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":2749,"description_truncated":false,"requirements":{"experience_years_min":null,"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":"2026-09-15T17:26:16Z"}],"visa":[],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":1,"p_active":0.817,"p_room":0.75,"age_days":52,"expected_fill_days":69,"reasons":["conf:0","velocity","win:late","comp:brand"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-ai-embedded-software-engineer-gcs","json_url":"https://alion.io/job/harmattan-ai-embedded-software-engineer-gcs.json","meta":{"generated_at":"2026-11-08T05:32:43Z","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":12013,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-09T00:00:00Z"}},"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-embedded-software-engineer-gcs"},{"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-embedded-software-engineer-gcs"},{"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-embedded-software-engineer-gcs"},{"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-embedded-software-engineer-gcs\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-ai-embedded-software-engineer-gcs"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":940421}},{"tool":"search_jobs","arguments":{"company":"harmattan.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":940421},"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.
