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 a confirmed Radar Signal Processing Engineer on Harmattan AI's Radar team in Paris, you will own the signal processing algorithms behind our next-generation airborne radar payload. You will take full ownership of your workstream, from algorithmic research through embedded implementation and flight validation, working with high autonomy and minimal oversight. You will work closely with the EW and RF analytics teams to translate product-level requirements into deployed, mission-ready capabilities.\nResponsibilities\nDesign and implement near-real-time algorithms for radar image formation, including inverse SAR (ISAR) processing of moving targets.\n\nDevelop and refine detection and tracking algorithms (e.g., EKF/UKF-based approaches) for moving target indication on airborne radar data.\n\nBuild jamming estimation capabilities, combining out-of-band spectral sniffing with in-band spatial covariance analysis, and the adaptive logic that drives radar behavior in response.\n\nContribute radar-derived observables and algorithms that support navigation when GNSS is unavailable.\n\nPrototype and port algorithms onto the selected embedded computing platform, balancing algorithmic performance against real-time and resource constraints.\n\nValidate algorithms end-to-end through hardware-in-the-loop bench testing, anechoic chamber campaigns, and real flight conditions, iterating quickly on results.\n\nWork closely with the EW and RF analytics modules to align signal processing development with system-level requirements.\n\nCandidate Requirements\n2 to 5 years of confirmed, hands-on experience in radar signal processing, gained in the defense or automotive radar industry preferably.\n\nSolid experience in Signal Processing on radar systems, either FMCW or pulsed, is required; exposure to moving target tracking, ECCM, radar-based navigation, or live/real-time processing is a strong plus.\n\nStrong theoretical foundations and genuine hands-on comfort with the underlying mathematics, not reliance on off-the-shelf tools or LLM-generated solutions.\n\nA quick thinker, comfortable taking full ownership of a technical scope end-to-end with minimal oversight.\n\nComfortable working in a fast, iterative cycle: writing code, running hardware-in-the-loop tests, and pushing validated changes independently.\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":2992,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2026-09-29T11:38:55Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.622,"p_room":1,"age_days":17,"expected_fill_days":74,"reasons":["conf:1","stale_co","velocity","win:early","comp:junior,brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-ai-signal-processing-engineer-radar","json_url":"https://alion.io/job/harmattan-ai-signal-processing-engineer-radar.json","meta":{"generated_at":"2026-10-18T10:37:14Z","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":15732,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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-signal-processing-engineer-radar"},{"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-signal-processing-engineer-radar"},{"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-signal-processing-engineer-radar"},{"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-signal-processing-engineer-radar\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-ai-signal-processing-engineer-radar"}]}
