We started with dispatch, the decision that determines how a $750B industry makes its money, and have since built across the rest of the front office. Our customers do $10M to $100M a year in revenue and run their operations on us.\nDispatch was the first step. The harder problems are ahead of us.\nOur team: 2x IMO medalists, 3x ICPC World Finalists and coaches, a Columbia professor, former founders, MIT, Waterloo, GT, and engineers from Citadel Securities, Stripe, Palantir, Two Sigma, and Meta. \nWhat we want you to own\nProduct infrastructure. Build and operate the infrastructure behind our real-time decision systems - durable execution, workflow orchestration, reliability, and performance for products customers run their business on.\n\nAgent infrastructure. Build the sandboxes, evaluation infrastructure, and harnesses our engineers use to develop and ship agent workflows, including the compute environments agents execute in.\n\nThe developer platform. CI/CD, deployment, local development, and internal tooling - the abstractions that let the team ship in days rather than quarters.\n\nReliability and observability. Instrumentation, monitoring, incident response, and debugging tooling for systems whose failure modes are often probabilistic rather than deterministic.\n\nCost and scale. Cloud and inference costs as the product footprint grows, and capacity and architecture decisions made before they become bottlenecks.\n\nPartner across engineering. Work directly with the product engineers building on your infrastructure, and with the customers affected by it.\n\nWho this is for\n3-6 years of engineering experience with meaningful ownership of infrastructure you built rather than inherited.\n\nZero-to-one experience. You've built infrastructure from scratch at a startup, or stood up new systems on a team inside a larger company.\n\nStrong infrastructure fundamentals across distributed systems, cloud infrastructure, networking, CI/CD, and observability.\n\nReal software engineering. Infrastructure at Probook means writing code and owning complex systems end to end, from design through production.\n\nBreadth over depth. You'd rather build new systems than operate mature ones, and you move up the stack when that's where the problem is.\n\nJudgment. You know when a system deserves careful architecture and when it deserves to be finished this week.\n\nCompensation & Benefits\nEquity: Meaningful early-stage equity\n\nSalary: $200K - $300K\n\nHealth: Comprehensive medical, dental, and vision\n\nPerks: $500 monthly Ramp card for commuting, meals, gym, etc. (plus $25 in nightly meal delivery credit) and really good office snacks\n\nAccess: Direct access to world-class investors and advisors","description_format":"text","description_chars":2756,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Field Service Management Software"],"lifecycle":[{"event":"open","at":"2026-09-30T04:32:02Z"}],"visa":[],"liveness":{"score":41,"band":"fade","label":"Fading","p_open":1,"p_active":0.541,"p_room":0.75,"age_days":21,"expected_fill_days":24,"reasons":["conf:0","stale_co","win:late"],"computed_at":"2026-10-21T05:46:15Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/probook-senior-software-engineer-infrastructure","json_url":"https://alion.io/job/probook-senior-software-engineer-infrastructure.json","meta":{"generated_at":"2026-10-21T18:53:48Z","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":26742,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":687474},"rest":"https://alion.io/mcp/rest/get_company?id=687474"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprobook-senior-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%2Fprobook-senior-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%2Fprobook-senior-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/probook-senior-software-engineer-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprobook-senior-software-engineer-infrastructure"}]}
