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.\nAs a Mechanical Engineer on Harmattan AI's Ground Control Systems (GCS) team, you will own the mechanical design of next-generation GCS hardware from concept through mass production. This may include a premium drone controller for ISR missions, a long-range antenna system for multiple drone vectors, or an interceptor drone launcher box. You will work at the intersection of mechanical design, RF integration, and electronics packaging to deliver field-ready, defense-grade products.\nResponsibilities\nEnd-to-End Design: Design and prototype drone controllers, antenna systems, and launcher enclosures from scratch-covering structural architecture, ergonomics, thermal management, and high environmental/waterproofing (IP rating) constraints.\n\nProduct Development: Own full product development cycles end-to-end, translating operator needs into rugged, field-ready designs.\n\nCAD Modelling & GD&T: 3D model in SolidWorks, including complex surface modelling, and produce detailed 2D drawings with GD&T to meet strict functional and assembly requirements.\n\nDFM/DFA: Apply DFM/DFA principles systematically to minimise unit cost and assembly time at scale, collaborating closely with suppliers specialising in plastic injection molding, large-scale thermoforming, sheet metal/structural steel fabrication, CNC, and die-casting.\n\nSimulation: Run FEA (stress, deformation) and thermal simulations (CFD/steady-state) to validate design choices early and reduce physical prototype cycles.\n\nTesting & Validation: Conduct mechanical stress, failure analysis, and environmental testing to validate designs for extreme field conditions.\n\nCross-Functional Collaboration: Collaborate daily with the Electronics and RF teams on PCB integration, internal routing, and RF constraints.\n\nSupply Chain Partnership: Partner with Supply Chain & Procurement on supplier qualification, cost targets, and the smooth transition from prototyping to mass production.\n\nDocumentation: Maintain detailed documentation of designs, test results, and production workflows to support knowledge sharing and continuous improvement.\n\nCandidate Requirements\nEducation: Engineering degree in Mechanical Engineering, Mechatronics, Aerospace Engineering, or equivalent.\n\nExperience: At least one full product development cycle taken from concept to mass production.\n\nManufacturing Expertise: Plastic injection molding experience with full DFM process and quality control; familiarity with CNC and die-cast molding.\n\nExperience with sheet metal fabrication, heavy metallic structures and large-scale thermoforming is highly desirable.\n\nCAD Proficiency: Advanced proficiency in SolidWorks, including complex surface modelling and 2D drawings with GD&T.\n\nPrototyping & Integration: Hands-on rapid prototyping experience (3D printing, CNC, etc.) and a proven track record of integrating embedded electronics into complex enclosures.\nNice to have:\n\nBasic FEA (stress, deformation) and thermal simulation (steady-state, CFD) experience.\n\nUnderstanding of mechanical linkages and actuator/cylinder kinematics for deployment or launching mechanisms.\n\nExperience in defense, aerospace, UAVs, or high-end consumer electronics hardware.\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":3862,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military Drones","Defense Manufacturing","Defense AI"],"lifecycle":[{"event":"open","at":"2026-07-10T11:40:14Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.415,"p_room":0.36,"age_days":112,"expected_fill_days":70,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/harmattan-mechanical-engineer-gcs","json_url":"https://alion.io/job/harmattan-mechanical-engineer-gcs.json","meta":{"generated_at":"2026-10-31T09:01:19Z","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":13597,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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-mechanical-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-mechanical-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-mechanical-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-mechanical-engineer-gcs\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fharmattan-mechanical-engineer-gcs"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":40719}},{"tool":"search_jobs","arguments":{"company":"harmattan.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":40719},"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);
