Our products are utilized by companies in designing and optimizing technology products, with applications ranging from designing airplanes and cars to wind turbines and quantum computing chips. Our customer base includes both household names and startups in emerging industries. Our company was founded by world-renowned leaders in simulation technology from Stanford University and MIT. Backed by top VC firms, we are poised to disrupt the billion-dollar engineering simulation industry with our fast-growing trajectory.\nTidy3D is a GPU-accelerated electromagnetic simulation product delivered as a cloud service. Behind the solver sits the platform that makes everything work: the Python client, the API, the job submission and scheduling layer, and the web application.\nWe are hiring a Software Engineer for the Tidy3D infrastructure team to own that platform. You will build new capability, keep the existing system healthy, and run the release and deployment process.\nResponsibilities\nDesign and build backend services for the Tidy3D platform.\nDevelop and operate the control plane: the APIs, services, and data model behind task submission, job state, and result delivery.\nBuild scheduling and resource management for simulation jobs across heterogeneous GPU capacity.\nHandle the operational concerns that come with a multi-tenant product: authentication, authorization, usage metering, and quota enforcement.\nHelp with the deployment of our products to customers.\nManage packaging and release to PyPI, and keep client and backend versions compatible across a long tail of installed versions.\nOwn the release pipeline end to end: versioning, CI/CD, staged rollout, and rollback.\nStandardize deployment patterns so the same product ships to our cloud, to customer-managed cloud accounts, and to on-premises installations.\nKeep production healthy.\nInstrument the platform and own its monitoring and alerting.\nRespond to incidents and debug across boundaries, from a customer's Python traceback down to a stuck job on a GPU node.\nManage cloud cost and capacity as usage grows.\nRequirements\n2+ years building and operating production cloud services. New grads with exceptional background are encouraged to apply too.\nStrong Python. You have written backend services in it, not just scripts. \nHands-on experience with a major cloud provider such as AWS, Docker, and Kubernetes.\nInfrastructure as code in production, ideally Terraform, with reusable modules rather than hand-managed environments.\nLinux fluency and comfort operating in production.\nNice to have\nGPU or HPC workloads, cluster schedulers such as Slurm, Ray, or Kueue, or high-throughput batch compute.\nDesigning, packaging, and distributing a developer-facing Python library or SDK.\nOn-premises, self-hosted, or air-gapped software deployment, and the enterprise requirements that come with it: SSO, network isolation, security review.\nA background in physics, engineering, or scientific computing, or prior work on technical software for technical users.\nOpen source contributions to infrastructure or scientific computing projects.\nBenefits\n Competitive compensation with equity of a fast-growing startup.\n Medical, dental, and vision health insurance.\n 401(k) Contribution.\n Gym allowance.\n Friendly, thoughtful, and intelligent coworkers.","description_format":"text","description_chars":3409,"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":["Equity","Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Simulation & Digital Twin Software","High-Performance Computing"],"lifecycle":[{"event":"open","at":"2026-07-31T00:00:00Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 7","filings_12m":7,"filings_prev_12m":7,"green_card_filings_12m":0,"median_offered_wage_usd":146786,"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":2}],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.76,"p_room":0.9,"age_days":16,"expected_fill_days":28,"reasons":["conf:5","velocity","win:mid"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/flexcompute-inc-software-engineer-infrastructure","json_url":"https://alion.io/job/flexcompute-inc-software-engineer-infrastructure.json","meta":{"generated_at":"2026-10-16T23:24:19Z","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":5337,"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":7971},"rest":"https://alion.io/mcp/rest/get_company?id=7971"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fflexcompute-inc-software-engineer-infrastructure"},{"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%2Fflexcompute-inc-software-engineer-infrastructure"},{"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%2Fflexcompute-inc-software-engineer-infrastructure"},{"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/flexcompute-inc-software-engineer-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fflexcompute-inc-software-engineer-infrastructure"}]}
