Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.\nAs democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.\nWe are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams - and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.\nThe role\nAt Helsing we use simulation to train and test autonomy at scale, long before anything touches real hardware. You will be part of a team that owns a system for simulating large-scale 3D worlds containing hundreds of actors, rendered in real time.\nYou will work on the internals of the simulation stack, including modelling of vehicles and other actors, integration of high-fidelity models from domain experts, sensor and environment simulation, networking, and interfacing with other components in a distributed system.\nTypical examples of day-to-day responsibilities include:\nBuilding and maintaining simulation platform internals: subsystem architecture, replication and multiplayer, performance profiling, and the interfaces used by other systems to orchestrate simulation.\n\nComposing simulated platforms from sensor, communications, situational awareness, effector, and control-loop models, and reasoning about the underlying physics such as flight dynamics, rigid-body behaviour, collision, and line of sight.\n\nOwning the trade-off between fidelity, throughput, and engineering cost, choosing the right point for each use case and validating the result against subject matter experts, integration tests, or downstream outcomes.\n\nIntegrating 3D models, animations, and effects from our Content Engineers into the simulation.\n\nInvestigating simulation bugs in order to bridge the gap from our simulation to a reference model.\n\nThe day-to-day\nYou will write production code that shapes both the simulation platform and the models running inside it, and you will decide how each piece of work is validated.\nYou will also translate mission requirements from subject matter experts into reusable simulation models, and make sure those models remain useful to the teams using simulation as part of their stacks.\nYou will contribute to high-impact projects and collaborate with people across many teams and backgrounds.\nYou should apply if you\nHave built real simulations well beyond toy projects, especially with game engines such as Unreal, Unity, or Godot, including gameplay frameworks, replication, and profiling tooling.\n\nWrite production code and bring proper software engineering practice into simulation work, including version control discipline, resolving ambiguity, and designing for the long term rather than the next demo.\n\nReason fluently about the trade-off between physical fidelity and simulation throughput.\n\nTranslate input from domain experts into models and behaviours, and know when real-world fidelity is needed and when it is expensive noise.\n\nJudge a simulation by what it enables rather than by whether it passes its tests, and treat a simulation that quietly misleads its users as a serious failure.\n\nNote: We operate at an intersection where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.\nNice to have\nExperience with entity-component-system architectures or agent-based modelling.\n\nExperience with distributed simulation standards such as HLA, DIS, RPR-FOM, NETN, or FMI.\n\nBackground in physics-heavy simulation, for example CFD, finite element methods, multi-body dynamics, or trajectory and 6DoF modelling.\n\nExperience with RF, electronic warfare, or radar simulation, including propagation and signal processing chains.\n\nFamiliarity with reinforcement learning environment APIs, or with software-in-the-loop and hardware-in-the-loop validation.\n\nExperience with Rust, CUDA, or MATLAB and Simulink.","description_format":"text","description_chars":4436,"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":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["National Security","Military Drones","Defense AI"],"lifecycle":[{"event":"open","at":"2026-10-04T20:02:04Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":17,"expected_fill_days":138,"reasons":["conf:1","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-09T06:01:00Z"},"pay":null,"html_url":"https://alion.io/job/helsing-simulation-engineer","json_url":"https://alion.io/job/helsing-simulation-engineer.json","meta":{"generated_at":"2026-10-10T00:22:22Z","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","counted_by":"address","units_charged":1,"used_today":547,"day_limit":5000,"remaining_today":4453,"minute_limit":60,"resets_at":"2026-10-11T00:00:00Z"}},"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":4739},"rest":"https://alion.io/mcp/rest/get_company?id=4739"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhelsing-simulation-engineer"},{"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%2Fhelsing-simulation-engineer"},{"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%2Fhelsing-simulation-engineer"},{"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/helsing-simulation-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhelsing-simulation-engineer"}]}
