We’re building AI Humans: a new interface that closes the gap between people and machines, free from the friction of today’s systems. Our real-time human simulation models let machines see, hear, respond, and even look real-enabling meaningful, face-to-face conversations. AI Humans combine the emotional intelligence of humans with the reach and reliability of machines, making them capable, trusted agents available 24/7, in every language, on our terms.\nImagine a therapist anyone can afford. A personal trainer that adapts to your schedule. A fleet of medical assistants that can give every patient the attention they need. With Tavus, individuals, enterprises, and developers can all build AI Humans to connect, understand, and act with empathy at scale.\nWe’re a Series B company backed by world-class investors including Sequoia Capital, Y Combinator, and Scale Venture Partners.\nBe part of shaping a future where humans and machines truly understand each other.\nThe Role\nWe're hiring a Senior Software Engineer to be a technical driver on Tavus's Conversational Video Interface, our multimodal real-time conversational product. It's a hands-on role. Your code runs in the middle of live conversations between people and PALs.\nWhat you'll own:\nShip features end-to-end. You'll take product priorities that start out loosely defined, like voice localization for accent support or multilingual sentence endpointing, and turn them into a spec, an architecture, and shipped features.\n\nPartner with Research to bring state-of-the-art real-time models into CVI. Sometimes that means dipping into research territory yourself.\n\nFix what you find. If you spot a flaky process or a slow path, you don't need a ticket or anyone's permission to go after it.\n\nWhat this role has shipped:\nGuided Browser Control: a framework that lets PALs drive a real web browser mid-conversation, narrating each click and scroll out loud\n\nMagic Canvas: interactive cards rendered right on the video stream. The PAL puts the right card up at the right moment: a question, a text box, a calendar, a chart, an alert\n\nMemories and Knowledge Base: the context layer that lets PALs recall past conversations and pull from document stores in real time, without breaking stride\n\nUtterance-to-utterance optimization: shaving hundreds of milliseconds off conversational turns\n\nWho you are:\nYou're proactive. When you see an issue, you fix it. Nobody has to ask.\n\nYou're autonomous. Given a loosely defined project, you figure out what \"done\" means, make the judgment calls, and deliver.\n\nYou're energized by unfamiliar problems. A lot of the work here has no playbook, and you'll take on projects outside your direct experience.\n\nYou adapt as priorities evolve. This space moves fast, and the most important thing to build can change as we learn. When it does, you adjust and keep moving.\n\nYou hold a high bar. What matters to you is how the product feels to the person on the other end of the conversation. Clean code and clever architecture are means to that end.\n\nYou're passionate about the future of interfaces. How people and computers interact is being reinvented right now, and you want a hand in shaping it.\n\nRequirements:\nFluent in Python, with real depth in concurrent programs. Low-level concepts (asyncio, multiprocessing, event loops, the GIL, shared memory) are dear friends, and you design with them in mind.\n\nYou've built real-time systems, whether video, audio, or model inference, and you know what a millisecond latency budget feels like.\n\nYou bring a senior track record: you set direction, own decisions, and get things over the finish line.\n\nYou explain complex things clearly, and you use that to teach the people around you.\n\nNice to haves:\nNone of these are required, but they'd help.\nExperience with GPUs and GPU management\n\nDeep experience with video streaming over WebRTC\n\nDeep experience with LLMs and agentic frameworks\n\nExtensive experience with low-level systems\n\nIf you don't check every box but this sounds like the work you want to be doing, apply anyway.","description_format":"text","description_chars":4120,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Conversational AI","Generative Video","Multimodal AI"],"lifecycle":[{"event":"open","at":"2026-09-11T16:56:25Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 4","filings_12m":4,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":227500,"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":2}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.284,"p_room":0.28,"age_days":113,"expected_fill_days":36,"reasons":["conf:1","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/tavus-senior-software-engineer-cvi","json_url":"https://alion.io/job/tavus-senior-software-engineer-cvi.json","meta":{"generated_at":"2026-10-31T22:54:16Z","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":35672,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":1185},"rest":"https://alion.io/mcp/rest/get_company?id=1185"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftavus-senior-software-engineer-cvi"},{"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%2Ftavus-senior-software-engineer-cvi"},{"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%2Ftavus-senior-software-engineer-cvi"},{"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/tavus-senior-software-engineer-cvi\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftavus-senior-software-engineer-cvi"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":754801}},{"tool":"search_jobs","arguments":{"company":"tavus.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":754801},"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.
