Patients and professionals deserve better.\nVocca builds AI voice agents that answer every call instantly, schedule and reschedule appointments, and free up staff to focus on what matters most: care.\nAlready trusted by 15 000+ providers, we’re transforming the patient-provider relationship, one call at a time.\nWant to shape the future of healthcare?\nJoin us !\nDiscover our company culture and values\n\nHere is a product teaser\n\nEliott's interview for Welcome to the jungle\n\nEliott's quick interview for Speedinvest\n\nArticles on our A round (techfundingnews, Maddyness, les echos, our blog)\n\nVocca in a few words\nVocca is an AI voice agent that answers 100% of the calls of medical centres. The patient calls, the AI books the appointment or answers the question, and the medical secretaries keep their time for the cases where a human is really needed.\n$20M raised, with the founders of Alan and Datadog as investors\n\nClose to 1 million calls a month going through the platform\n\nOpening the US market\n\nThe problem\nEvery medical practice runs on software that holds its calendar and its patients. There are dozens of different ones. Most were built twenty years ago and some have no API at all. To book an appointment during a call, our AI agent has to read and write in that software in real time, while the patient waits on the line. On several of these systems, Vocca is the only integrator in the world.\nThis is the work with the most direct impact on the business. A clinic whose software is connected to our agent does not switch. Retention, pricing power, our lead over competitors: it all depends on these integrations. Every software we cannot connect is a clinic we cannot sign.\nThe next step is writing back. Today the agent reads and books. Tomorrow it updates records in EHR, PMS and RIS systems, which raises the reliability bar a lot. In the US, we are opening the dental software ecosystem, with the compliance work that comes with it (HIPAA, SOC2).\nThere is no product manager on this scope. You would be the one deciding.\nWhat you will own\nThe architecture of our booking layer. Today it is code written provider by provider, under pressure, partly in Python. It is becoming one unified layer in TypeScript that handles the rules of each medical centre, where adding a new software takes days, not weeks.\n\nSpeed and reliability at close to 1M calls a month. A call to a clinic software can take several seconds, and the patient cannot wait. You decide how we detect a booking failure in a clinic within 24 hours and what a healthy integration looks like.\n\nThe roadmap of your scope. You decide which software we connect first, with the sales, ops and support teams and the clinics themselves, and you prove it worked with a number: bookings that go through, failures caught, clinics signed.\n\nThe relationship with the software vendors, in France and in the US. The hard integrations are the ones nobody else wants to do. They are what makes Vocca hard to replace.\n\nThe team. You define how this scope works (reviews, documentation, technical decisions), you take part in hiring the next engineers and you help them ship in their first week.\n\nHow we build\nExperimental, not R&D. You test, you prove with data, you ship. Challenging a decision means coming back with a result, not a debate.\n\nShip, then fix the last 1%. We ship the version that works, then fix the last 1% when it shows up. With AI, this trade off is much cheaper than before. The judgment about what not to touch is yours.\n\nAI, seriously. Agents in every workflow, Claude Max provided. A migration estimated at 3 months was done in 2 weeks.\n\nClose to the field. You talk every day with the ops team that deploys clinics, the support team that hears when something breaks and, when it matters, the clinics and the software vendors themselves.\n\nStack\nTypeScript everywhere (Node, monorepo), PostgreSQL, REST and SOAP APIs from software vendors. We are migrating our last Python services to TypeScript over the coming months.\nWho does well here\n6 to 10 years building products in production, mostly in startups that were growing fast, with at least one place where you stayed long enough to see your system live in the long run.\n\nYou have built something that mattered: an early engineer at a startup that took off, a system you launched that real users depended on. You can tell us who it was for, what problem it solved and which number moved.\n\nYou have integrated systems you did not control and you know the difference between a clean API and the real world.\n\nStrong in TypeScript and Node, comfortable across the stack.\n\nYou think about the product and the business as much as the code. You can say no, reduce the scope and explain a technical decision to a founder in two minutes.\n\nYou are at ease with clients and partners, in French and in English.\n\nProbably not for you if you want to manage without coding, or if you need a stable, fully specified environment before you move.\nWhat we expect from you\nFirst week. Onboarded on the stack, your first fix on a live integration is in production.\n\nFirst month. You own one integration end to end, from the software vendor to production, and show what it changed. You write down how our booking layer should evolve.\n\nFirst 3 months. The unified booking layer in TypeScript is the standard. Adding a new software takes days, not weeks. We detect a booking failure in any clinic within 24 hours.\n\n6 to 12 months. Our first US integrations run in production. You have hired at least one engineer and they ship on their own.\n\nProcess: 4 steps, fast\n45 min with Nans (Talent).\n\n45 min with Pierrick, Head of Engineering.\n\n2h in our office with the engineering team: coding without AI and a real conversation about architecture.\n\n30 min with Hugo, CTO.\n\nThen references and an offer. When the match is obvious, we have made an offer in 24 hours. You get feedback at every step.\nPractical\nParis, rue d'Alexandrie (Sentier), new offices.\n\nHybrid, 3 days at the office.\n\nBSPCE.\n\nClaude Max provided.\n\nWe aim to keep the process within 30 days. You’ll receive continuous feedback throughout.\nWhy should you join Vocca?\nAn entrepreneurial adventure, with a supportive, high-energy, execution-focused team\n\nA product already live, with delighted customers in a fast-growing market (healthcare automation, voice AI)\n\nA true scaling phase, with everything still to build\n\nReal responsibilities from day one\n\nWe hire people, not roles.\nIf you're excited about our opportunities but don't check every box, we'd love to hear from you. Everyone, no matter how underrepresented, should feel free to apply as it can only bring learnings or success. If you identify yourself as a woman: Did you know that research shows women often apply only when meeting 100% of requirements?\nWe'll be thrilled to receive your application!","description_format":"text","description_chars":7035,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Patient Access & Booking"],"lifecycle":[{"event":"open","at":"2026-09-11T11:26:37Z"}],"visa":[],"liveness":{"score":21,"band":"cold","label":"Long shot","p_open":1,"p_active":0.57,"p_room":0.36,"age_days":62,"expected_fill_days":34,"reasons":["conf:4","win:tail","crowd:"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/vocca-senior-software-engineer-typescript-integrations-70-90k-bspce","json_url":"https://alion.io/job/vocca-senior-software-engineer-typescript-integrations-70-90k-bspce.json","meta":{"generated_at":"2026-11-06T05:38:53Z","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":9914,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":686867},"rest":"https://alion.io/mcp/rest/get_company?id=686867"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvocca-senior-software-engineer-typescript-integrations-70-90k-bspce"},{"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%2Fvocca-senior-software-engineer-typescript-integrations-70-90k-bspce"},{"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%2Fvocca-senior-software-engineer-typescript-integrations-70-90k-bspce"},{"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/vocca-senior-software-engineer-typescript-integrations-70-90k-bspce\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvocca-senior-software-engineer-typescript-integrations-70-90k-bspce"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":737058}},{"tool":"search_jobs","arguments":{"company":"vocca.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":737058},"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.
