Too toxic. Too remote. Too dangerous for humans to handle. That’s where we come in.\nAt HDT, we build robotic arms and unmanned ground vehicles (UGVs) with military-grade strength and precision engineering, built for the extremes and adaptable to any challenge. Behind the toughest hardware is a team energized by complex problems. Bring us a challenge, and we’ll engineer the solution.\nThat’s the mindset. That's the mission. That’s Built for Brutal.\nThe Senior Mechanical Engineer - Robotics will manage and drive all aspects of design and engineering including requirements analysis, concept generation, mechanical design, implementation, testing, and documentation. The candidate will work on multiple projects of moderate size or on portions of major projects.\nThe successful candidate will have experience with machine design, sensors, transmissions, electric motors, bearings, kinematic linkages, material selection, structural analysis, people management, as well as hands-on debugging. The Sr. ME- Robotics will have the ability to translate objectives to results and deliverables, while working in a highly-collaborative, multi-disciplinary team environment.\nESSENTIAL DUTIES AND RESPONSIBILITIES:\nStrong robotics fundamentals (kinematics, dynamics, statics, sensing, etc.)\nOversees a team of engineers tracking and reporting progress\nKnowledge of 3D mechanical CAD design (Solidworks preferred)\nManaging the design process & drafting of production drawings for machined parts, fabrications and weldments, COTS parts, and assemblies\nStatic and dynamic structural analysis using a variety of tools including both hand calculations and finite element analysis (FEA)\nUnderstands materials needed to optimize strength, weight, cost, and performance\nUnderstands machining and manufacturing processes to optimize cost without sacrificing performance\nAbility to conceptualize and implement the design of complex mechanisms\nPerforms complex design and research tasks; develops mechanical products and systems such as robots, actuators, instruments, sensors, and overall mechatronic systems\nDesigns a complete project, system, component, or process and preparing complete project documents\nDesigns and conducts experiments, analyzes and interprets data, formulates and solves problems\nManages testing efforts\nApplies risk mitigation\nAdheres to all quality and safety standards.\nSupports other projects and performs duties as assigned.\nSupports, communicates, reinforces and defends the mission, values and culture of the organization.\nEXPERIENCE / KNOWLEDGE / SKILLS / ABILITIES :\nExperience with robotics/mechatronics\nKnowledge of Geometric Dimensioning and Tolerancing (GD&T)\nExperience with finite element analysis (FEA). SolidWorks COSMOS or equivalent is sufficient.\nExperience with sizing actuators i.e. brushless electric motors, including the design of custom motors, and transmissions\nExperience with strain gages and load cells described\nExperience with other sensors such as hall-effect, angular position, and temperature sensors\nPossesses strong computer skills with demonstrated proficiency in standard business software packages (e.g., Microsoft Office). Must possess excellent skills with Microsoft Excel and Word\nQuality orientation and high attention to detail\nMust be able to read, speak and understand English\nAbility to work independently with limited supervision and in a team environment\nEDUCATION / EXPERIENCE:\nBS degree in Mechanical Engineering required, MS preferred\n5+ years work experience (Government contractor experience preferred)\nWORK ENVIRONMENT: The work environment characteristics here are representative of those an employee encounters while performing the essential functions of this job:\nWork is accomplished in a typical office environment with adequate environmental (heating/cooling) control. The noise level in the work environment is moderate due to noises associated with computer equipment and environmental control systems. \nThis role routinely uses standard office equipment such as computers, phones, photocopiers and filing cabinets\nAccess to operations and manufacturing areas may involve exposure to loud noises, dust, fumes, oils, and fluctuations in temperature\n* This specific position requires U.S. Citizenship. The applicant must be able to obtain and maintain a Secret clearance. An active Secret clearance is preferred but not required.","description_format":"text","description_chars":4442,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":true,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-03T03:07:03Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.562,"p_room":0.35,"age_days":48,"expected_fill_days":22,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":120000,"is_top_pay":false},"html_url":"https://alion.io/job/hdt-global-sr-mechanical-engineer-robotics","json_url":"https://alion.io/job/hdt-global-sr-mechanical-engineer-robotics.json","meta":{"generated_at":"2026-10-14T00:10:48Z","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":331,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":2195196},"rest":"https://alion.io/mcp/rest/get_company?id=2195196"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhdt-global-sr-mechanical-engineer-robotics"},{"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%2Fhdt-global-sr-mechanical-engineer-robotics"},{"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%2Fhdt-global-sr-mechanical-engineer-robotics"},{"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/hdt-global-sr-mechanical-engineer-robotics\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhdt-global-sr-mechanical-engineer-robotics"}]}
