You would own the evidence that this system is safe to put in front of\n\npatients, on your own judgement, and tell us when the answer is no. That isn't a job we can hand to\n\nsomeone still learning what to measure.\n\nYou would not be building a voice stack. We use a third-party voice platform that already handles the\n\ntelephony, the speech recognition and synthesis, and the knobs for end-of-speech detection and\n\ninterruption. What it does not do is tell us whether any of that is working well enough for patients, and it\n\ngives us no way to check that a change hasn't made things worse. That's the job.\n\nSo you'd own the conversation and the evidence about it: how the assistant behaves when a caller\n\ninterrupts, corrects themselves or won't answer; how fast the whole thing responds once a round trip to\n\nour backend is in the loop; and the body of test cases we run before every change.\n\nYou need\n\nTo have run a phone or voice assistant that took real calls from real users, and to be able to tell us what its response time was and how you measured it. Having built the audio pipeline yourself is fine but not the point — we care that you know what to measure and what good looks like.\n\nTo have tuned a voice system rather than only shipped one: end-of-speech detection, barge-in, how long to wait before assuming the caller has finished. You'd be doing this against a vendor's settings rather than your own code, and their own documentation says clean barge-in can't be guaranteed on phone audio.\n\nTo know what happens to speech recognition accuracy when the audio comes down a phone line instead of a good microphone, and to have measured it rather than read about it.\n\nA way of testing conversation changes that doesn't rely on listening to a few calls and hoping. This is the centre of the role. Whatever form it took — a replay harness, a scored scenario set, anything — we want to hear how it worked and where it let you down.\n\nEnough Python to build that harness and the tooling around it.\n\nWe are considering candidates who work through Ukrainian FOP.\n\nNice to have\n\nHaving worked against a closed voice platform, with the frustrations that brings, rather than only your own stack.\n\nTelephony background: SIP , WebRTC, Asterisk, Twilio or similar. Useful for knowing why calls sound the way they do, though you would not be running any of it.\n\nWork with health data, or any other field where getting it wrong has consequences.\n\nGerman, though we're not counting on it.\n\nYou don't need\n\nTo speak German.\n\nTo have built streaming audio infrastructure, a turn-taking system or a speech pipeline. The platform does that, and rebuilding it isn't on the table.\n\nTo know PHP or anything about our existing backend. Another team builds the endpoints you'd call.\n\nTo have trained a model from scratch.","description_format":"text","description_chars":3080,"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":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-29T12:21:41Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":29,"reasons":["seen:4","velocity","win:early"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/kaworks-senior-voice-ai-engineer-evaluation-and-reliability","json_url":"https://alion.io/job/kaworks-senior-voice-ai-engineer-evaluation-and-reliability.json","meta":{"generated_at":"2026-11-03T08:23:10Z","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":11979,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":4485845},"rest":"https://alion.io/mcp/rest/get_company?id=4485845"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkaworks-senior-voice-ai-engineer-evaluation-and-reliability"},{"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%2Fkaworks-senior-voice-ai-engineer-evaluation-and-reliability"},{"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%2Fkaworks-senior-voice-ai-engineer-evaluation-and-reliability"},{"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/kaworks-senior-voice-ai-engineer-evaluation-and-reliability\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkaworks-senior-voice-ai-engineer-evaluation-and-reliability"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3453583}},{"tool":"search_jobs","arguments":{"company":"kaworks.de","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3453583},"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.
