This role is central to establishing standardized testing practices, simulation environments, and automation infrastructure that enable high-confidence validation of mission-critical systems.\nYou will define test software across the organization-creating a cohesive ecosystem that spans simulation, hardware-in-the-loop (HIL), integration, and system-level testing-while enabling teams in different regions to operate efficiently within a shared framework.\nKey Responsibilities\nTest Framework Architecture: Design and evolve a modular, global test framework supporting unit, integration, system, and simulation-based testing. Define reusable abstractions, APIs, and libraries for consistent implementation, including fault injection scenarios such as sensor dropouts, thruster misfires, and communication delays.\nSimulation & Test Infrastructure: Architect scalable simulation environments and virtual testbeds with seamless HIL/SIL integration, covering orbital mechanics, space environments (vacuum, radiation, thermal), and spacecraft dynamics including attitude control and propulsion.\nGlobal Standardization & GovernanceEstablish: common testing strategies, naming conventions, data formats, and reporting standards across regions. Define quality metrics, coverage standards, and quality gates; lead architecture and test design reviews to enforce best practices.\nAutomation & CI/CD: Build and standardize automated test pipelines within CI/CD workflows, ensuring tests are reliable, reproducible, and scalable across distributed environments.\nPerformance & Mission Scenario Testing: Ensure test systems support large-scale simulations, high data throughput, and long-duration runs - including thousands of simulated missions across launch windows, environmental variations, and anomaly scenarios. Optimize for speed, determinism, and debuggability.\nCross-Functional Leadership: Collaborate with global engineering teams to drive adoption of the test framework. Contribute to resource estimation, schedule planning, and risk identification. Embody ispace values - Diversity, Integrity, Respect, Collaboration, and Accountability - and stay current on emerging tools and methodologies.\nBasic Qualifications\nB.S. or M.S. in Computer Science, Software Engineering, Aerospace Engineering, or related field\n5+ years of software engineering experience with significant focus on test systems or infrastructure\nProven track record designing scalable test frameworks or platforms\nStrong programming skills in Python, C++, Java, or similar\nExperience with automated testing, CI/CD systems, and test orchestration tools\nSolid understanding of software V&V principles\nFamiliarity with ITAR/EAR requirements for sharing technical data internationally\nWhat Makes You Stand Out\nExperience with simulation environments (MATLAB/Simulink, ROS, or custom platforms) and HIL/SIL testing\nBackground in safety-critical industries (aerospace, automotive, robotics, or defense)\nKnowledge of distributed systems, cloud-based test infrastructure, and LabVIEW\nFamiliarity with orbital mechanics, control theory, and embedded flight software constraints\nExperience interpreting telemetry and simulation data outputs\nAbility to thrive in a fast-paced environment with evolving priorities; willingness to travel (Compensation and Benefits\nWe welcome candidates with diverse experience levels and evaluate the best fit on an individual basis. Your final job level and salary will be determined based on your skills, experience, and the impact you can bring to the role.\nJG4- $101,000- $151,000\nJG5 - $126,000-$189,000\n·Health Coverage: Competitive medical, vision, and dental plans, with 100% company-paid options available for employees.\n·Hybrid Work: Flexibility to work remotely and in-office, depending on your role and the stage of our program.\n·Commuter Perks: Company-paid RTD EcoPass for buses and light rail.\n·Lunch Perks: Monthly stipend to enjoy meals from our café.\n·Paid Time Off: 18 vacation days, 6 sick days, and 17 paid holidays.\n· Retirement: 401(k) plan with company matching.\n·Travel: Opportunities for domestic and international travel.\n·Stock Options: Participation in our stock option program.\n·Learning & Development: Ample opportunities to grow, including lunch-and-learns, skills training, and stipends for professional development.\n· Team Culture: A fun and casual environment with regular team gatherings, including monthly engagement events to connect and unwind.","description_format":"text","description_chars":4704,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Hybrid work","Professional development","Retirement plans","Stock options"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Space Services"],"lifecycle":[{"event":"open","at":"2026-05-29T20:15:48Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 8 · green card filings: 3","filings_12m":8,"filings_prev_12m":22,"green_card_filings_12m":3,"median_offered_wage_usd":115682,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":4}],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.445,"p_room":0.28,"age_days":139,"expected_fill_days":59,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/ispace-software-simulation-test-design-engineer","json_url":"https://alion.io/job/ispace-software-simulation-test-design-engineer.json","meta":{"generated_at":"2026-10-16T16:06:40Z","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":535,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":7409},"rest":"https://alion.io/mcp/rest/get_company?id=7409"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fispace-software-simulation-test-design-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%2Fispace-software-simulation-test-design-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%2Fispace-software-simulation-test-design-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/ispace-software-simulation-test-design-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fispace-software-simulation-test-design-engineer"}]}
