Coval is the evaluation platform for conversational AI: we help enterprise teams simulate before launch, observe in production and review with humans. This role owns the machinery that makes all of it run.\nThat means the distributed pipelines, queues and orchestration that score tens of thousands of conversations a day, plus the data layer and cost controls underneath them. You’ll own the systems enterprises run their voice agents through, and you’ll get in while they’re still being built.\nWhat you’ll do\nBuild out our distributed execution engine: the workers, queues and orchestration that fan out tens of thousands of simulated conversations a day and bring back scores\nOwn the data side, from the databases holding conversations, audio and judge results to the pipelines that move them between stages\nMake real cost trade-offs. Every model call and storage byte has a price, and you keep unit economics sane as volume climbs\nStand up and maintain the environments where our LoRA training jobs run, as a key part of the plumbing for our ML work\nWhat we’re looking for\n4+ years building real systems, with Python and AWS as home turf\nExperience with managed services and Terraform, which we use heavily, and the judgment to know when a managed service stops being the right answer\nYou’ve operated something under load and know what it feels like when a queue backs up at 2am\nYou can look at a half-built system and decide what to finish, what to fix, what to start next and what to buy time on\nHigh agency: on a small Series A team, nobody writes your tickets. You figure out what matters next and take it there\nAmbitious and kind. As a founding member of the engineering team, you’ll shape the architecture and the standards everyone else builds against","description_format":"text","description_chars":1814,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Conversational AI","AI Evaluation & Observability"],"lifecycle":[{"event":"open","at":"2026-10-27T01:41:52Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"Filed H-1B visas in the last two years","filings_12m":0,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":5,"expected_fill_days":36,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/coval-senior-platform-engineer","json_url":"https://alion.io/job/coval-senior-platform-engineer.json","meta":{"generated_at":"2026-11-01T16:17:21Z","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":25064,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":47880},"rest":"https://alion.io/mcp/rest/get_company?id=47880"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcoval-senior-platform-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%2Fcoval-senior-platform-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%2Fcoval-senior-platform-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/coval-senior-platform-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcoval-senior-platform-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3306699}},{"tool":"search_jobs","arguments":{"company":"coval.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3306699},"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.
