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 Signal Processing Engineer, you own the algorithmic core of our drone-to-ground radio link - the system that keeps drones connected, controllable, and streaming in contested environments. You design the waveform, the anti-jam logic, and the signal intelligence that turn radio waves into a reliable link under hostile conditions, working hand-in-hand with RF hardware, FPGA, and software engineers to bring your algorithms from theory to flight.\nResponsibilities\nWaveform Design: Design modulation, coding, and equalization schemes for a robust, low-latency radio link.\n\nAnti-Jamming (ECCM): Build algorithms that keep the radio link alive under active jamming.\n\nSignal Intelligence (SIGINT): Detect and characterize other radio emitters in the operating environment.\n\nMesh Networking: Optimize protocols so multiple radio units share the airwaves without collision.\n\nAI-Assisted Processing: Apply machine learning to jamming detection and channel prediction where it improves field robustness.\n\nField Validation: Take algorithms from simulation to lab bench to real flight test.\n\nRadio System Integration: Work daily with RF hardware and FPGA engineers to bring designs into a fielded radio.\n\nCandidate Requirements\nMaster's or PhD in Electrical Engineering, Signal Processing, or Applied Mathematics.\n\n8-12 years designing radio or communication systems, from algorithms to deployed products.\n\nHands-on experience with modem or waveform design: modulation, coding, synchronization, equalization.\n\nSolid grounding in probability, DSP, and information theory; comfortable deriving solutions from first principles.\n\nPractical awareness of RF hardware and FPGA constraints (latency, precision, real-time processing).\n\nExposure to ECCM, SIGINT, or mesh networking is a strong plus.\n\nClear communicator across RF, FPGA, and software disciplines.\n\nFluency in English required; French is a plus.\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":2585,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2026-09-05T10:21:51Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.583,"p_room":0.6,"age_days":69,"expected_fill_days":74,"reasons":["conf:0","stale_co","velocity","win:late","crowd:brand"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-ai-signal-processing-engineer-radio","json_url":"https://alion.io/job/harmattan-ai-signal-processing-engineer-radio.json","meta":{"generated_at":"2026-10-28T22:08:20Z","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":29879,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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-radio"},{"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-radio"},{"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-radio"},{"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-radio\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-ai-signal-processing-engineer-radio"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":239558}},{"tool":"search_jobs","arguments":{"company":"harmattan.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":239558},"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);
