Behind them sits a platform that runs large, long-lived computational workloads: fleets of agents and numerical solvers, very large binary artifacts, and results that have to be correct because real hardware depends on them.\nThe role\nYou will build the infrastructure this platform runs on. It is a small set of hard, coupled systems, and you will own one or more of them end to end: design, implementation, operations, and on-call.\nDurable orchestration. Workloads run for days across thousands of tasks. They must survive failure, checkpoint, resume, and stay steerable by humans and agents mid-flight.\n\nVersioned artifact storage. Git-style semantics (branch, diff, merge) over large binary artifacts, on content-addressed storage with aggressive deduplication, at terabyte-to-petabyte scale.\n\nCI and validation pipelines. Merge queues where the gates are expensive computed checks, not just unit tests, and a change is validated by actually running it.\n\nCompute execution fabric. Scheduling heterogeneous workloads, many on GPUs, across cloud fleets: batching, prioritization, budget enforcement, and streaming results back in real time.\n\nAgent harness. Sandboxed, reproducible, observable execution for long-running autonomous agents that write code, run tools, and spend real compute.\n\nYou might be a fit if\nYou have 5+ years building and operating distributed systems in production; for the Staff level, 10+ years and a system you are known for.\n\nYou have seen real scale and carry the scars: at a database, streaming, or orchestration company; a multiplayer game backend; internet-scale media storage; a simulation or GPU-compute platform; or a build/CI system serving thousands of engineers.\n\nYou have gone deep in at least one of: durable workflow engines, storage engines or content-addressed storage, high-throughput schedulers, or build/merge systems.\n\nYou write production systems code (Go, Rust, or C++) and are effective in Python.\n\nYou have carried a pager for stateful systems in production.\n\nYou want your work to matter in the physical world.\n\nStrong pluses\nGPU scheduling or HPC job orchestration (Slurm, Ray, Kubernetes batch).\n\nDeterministic simulation testing or serious correctness culture (FoundationDB, TigerBeetle, Jepsen lineage).\n\nExposure to scientific or geometric computing. Not required; we will teach you the domain.\n\nExperience building infrastructure for AI agents: sandboxing, session persistence, tool execution.","description_format":"text","description_chars":2541,"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":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Wealth Management & Financial Advisors","Asset Management & Funds"],"lifecycle":[{"event":"open","at":"2026-10-07T18:39:55Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":6,"expected_fill_days":37,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-14T06:34:16Z"},"pay":null,"html_url":"https://alion.io/job/prometheus-senior-staff-software-engineer-product-infrastructure","json_url":"https://alion.io/job/prometheus-senior-staff-software-engineer-product-infrastructure.json","meta":{"generated_at":"2026-10-14T20:22:51Z","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":"search","counted_by":"address","units_charged":0,"used_today":0,"day_limit":null,"remaining_today":null,"minute_limit":null,"resets_at":"2026-10-15T00:00:00Z"}},"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":79790},"rest":"https://alion.io/mcp/rest/get_company?id=79790"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprometheus-senior-staff-software-engineer-product-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%2Fprometheus-senior-staff-software-engineer-product-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%2Fprometheus-senior-staff-software-engineer-product-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/prometheus-senior-staff-software-engineer-product-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprometheus-senior-staff-software-engineer-product-infrastructure"}]}
