In this role, you will collaborate with software and domain experts to design and implement software that solves complex, real-world problems.\nYou will help build and support software across a variety of cutting-edge domains, including computer vision, atmospheric and physics-based modeling, high-performance computing (HPC), space domain awareness, and machine learning.\nWhat You Bring\nB.S. or advanced degree (M.S./Ph.D.) in computer science, math, science, or an engineering field.\nStrong experience with object-oriented development and C++ programming. An enthusiasm for or interest in adopting modern C++23 practices is highly valued.\nA track record of learning new paradigms and a desire to build clean, high-quality code.\nU.S. citizenship and a willingness to undergo a background investigation. Ability to perform some work at government and/or customer sites in the Northern Virginia (NoVA) area. An active security clearance is a plus, but not required to apply.\nSkills We Use (Experience in any of these is a plus)\nWe don't expect anyone to know all of these! If you have experience or interest in a few of these areas, we want to hear from you:\nPython, Java, TypeScript, C++ Boost, or Eigen\nSupercomputing (OpenMP, threads, MPI, GPUs/CUDA)\nCross-platform development (Linux and Windows)\n3D graphics (OpenGL, Vulkan, WebGL)\nUser interface development (Qt, Material UI)\nPhysics/aerospace modeling, orbital mechanics, directed energy, or simulation frameworks like AFSIM\nMachine learning frameworks (PyTorch, TensorFlow) and core data analysis tools (NumPy, pandas)\nOur Interview Process\nTo help us understand your coding style and engineering skills, we will request a representative sample of your code early in the evaluation process. This can be something you've written for work, for a class, or a personal project you built just for fun.\nSee our generous and flexible benefits at our https://www.stellarscience.com/careers#benefits","description_format":"text","description_chars":2150,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Simulation & Digital Twin Software","Custom Software Development","Scientific & Lab Software"],"lifecycle":[{"event":"open","at":"2026-10-28T20:50:39Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":30,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/stellar-science-scientific-software-developer-dc-nova-stellar-science-2","json_url":"https://alion.io/job/stellar-science-scientific-software-developer-dc-nova-stellar-science-2.json","meta":{"generated_at":"2026-10-31T07:51:19Z","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":11682,"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":3854040},"rest":"https://alion.io/mcp/rest/get_company?id=3854040"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fstellar-science-scientific-software-developer-dc-nova-stellar-science-2"},{"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%2Fstellar-science-scientific-software-developer-dc-nova-stellar-science-2"},{"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%2Fstellar-science-scientific-software-developer-dc-nova-stellar-science-2"},{"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/stellar-science-scientific-software-developer-dc-nova-stellar-science-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fstellar-science-scientific-software-developer-dc-nova-stellar-science-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3420579}},{"tool":"search_jobs","arguments":{"company":"stellarscience.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3420579},"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.
