Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond.\nWe operate at the cutting edge of Applied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better.\nJOB SUMMARY\nAt the core of every robot policy we ship is a simulation platform that has to be fast enough for RL training, accurate enough for controls validation, and stable enough to be the team’s daily driver. As Staff Simulation Engineer for Core Simulation Platform, you’ll contribute to the architecture and development of that platform alongside senior team members, applying strong C++ and Python skills, robotics fundamentals, and modern simulator experience to keep the platform robust, performant, and parallel.\nESSENTIAL DUTIES AND RESPONSIBILITIES\nContribute to the architecture and development of the core simulation platform - high-performance digital twins that serve as the foundation for policy training, controls validation, and CI/CD integration testing.\nHelp build and scale cloud-native simulation pipelines capable of generating millions of experience hours per day, parallelizing physics and rendering for rapid policy iteration.\nImprove sim-to-real transfer through advanced contact models and actuator dynamics that help policies trained in simulation transfer to physical humanoid hardware.\nDevelop sensor-realistic environments (camera, LiDAR, depth) that challenge the perception stack with dynamic and diverse worlds.\nShip platform improvements that visibly reduce iteration time for RL, controls, and perception teams.\nWork with Controls, AI Research, and Perception teams to support their evolving simulation needs as the platform grows.\nSKILLS AND REQUIREMENTS\nExcellent C++ and/or Python programming skills\nFamiliar with software development best practices: CI/CD, automated testing, and code quality standards\nUnderstanding of robotics concepts: kinematics, dynamics, controls, system identification\nExperience with modern robotic simulators (Isaac Lab, MuJoCo, or equivalent)\nUnderstanding of Reinforcement Learning and VLAs, with research or production experience\nExperience with large-scale training workloads - deploying parallel simulations on cloud platforms (AWS, GCP, Azure) with distributed computing frameworks (e.g., Ray, Kubernetes)\nEDUCATION and/or EXPERIENCE\nMaster’s or PhD in Computer Science, Robotics, Electrical Engineering, or related field (or equivalent experience)\n5+ years of experience in robotic simulation, software engineering, or related fields\nPHYSICAL REQUIREMENTS:\nProlonged periods of sitting at a desk and working on a computer\nMust be able to lift 15 pounds at times\nVision to read printed materials and a computer screen\nHearing and speech to communicate\n*This is a direct hire. Please, no outside Agency solicitations. \nApptronik provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws.","description_format":"text","description_chars":3671,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Robotics AI","Robotic Components & Sensors","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-10-21T14:54:23Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 23","filings_12m":23,"filings_prev_12m":20,"green_card_filings_12m":0,"median_offered_wage_usd":157500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":20}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":7,"expected_fill_days":77,"reasons":["conf:3","stale_co","velocity","win:early"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/apptronik-staff-simulation-engineer-core-simulation-platform","json_url":"https://alion.io/job/apptronik-staff-simulation-engineer-core-simulation-platform.json","meta":{"generated_at":"2026-10-30T03:39:08Z","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":4919,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":47983},"rest":"https://alion.io/mcp/rest/get_company?id=47983"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fapptronik-staff-simulation-engineer-core-simulation-platform"},{"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%2Fapptronik-staff-simulation-engineer-core-simulation-platform"},{"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%2Fapptronik-staff-simulation-engineer-core-simulation-platform"},{"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/apptronik-staff-simulation-engineer-core-simulation-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapptronik-staff-simulation-engineer-core-simulation-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3008943}},{"tool":"search_jobs","arguments":{"company":"apptronik.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3008943},"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.
