Our agents answer calls, reply to emails and WhatsApp messages, make bookings, take payments, and operate the CRM in the same way a human would.\nWe founded Elyos in June 2023 and took part in the Y Combinator S23 batch. Our founders spent four months in San Francisco living and breathing AI. Since then, we’ve been growing revenue ~30% month on month and shipping fast. It’s been wild so far - and we’re just getting started. We recently raised a $13m series A to turbocharge our growth.\nAt Elyos, we’re building AI voice agents that help trades businesses run smoother, scale faster, and deliver better customer experiences. As one of our founding engineers, you won’t just build software - you’ll shape the way Elyos works, interacts with customers, and grows. If you love building things from the ground up, solving complex technical challenges, and working with cutting-edge AI tech, you’re in the right place.\nWhat You’ll Do\nBuild and ship core product features across our stack (Python, TypeScript, cloud infra, event-driven systems, third party integrations).\n\nOwn the lifecycle: work directly with customers to understand their needs, scope solutions, and deliver outcomes.\n\nMove fast, when it matters: know when to hack an MVP to deliver value quickly, and when to invest in scalable foundations.\n\nRaise the bar: use best practices everywhere (e.g testing, documentation, reliability, security) and help others do the same.\n\nWho You Are\nCustomer-obsessed: You start with the customer. You empathise with their needs, ask the right questions, and build with their success in mind.\n\nBiased for action: You try stuff. You move quickly, experiment often, and aren’t afraid to learn in public.\n\nOwner’s mindset: You don’t wait for permission - you take responsibility for outcomes and raise the bar for the whole team.\n\nAmbitious & bold: You think big and take bets. You’re excited to explore new ideas, technologies, and markets that others might shy away from.\n\nTeam-first collaborator: You make the next pot of coffee. No task is beneath you, and you care about building a team where everyone can thrive.\n\nCare deeply: You give a shit about the quality of your work. If something you built isn’t great, it nags at you until you make it better.\n\nWhat You Bring\nStrong fundamentals in software engineering - you can design, debug, and ship reliable systems.\n\nProficiency with at least one of our core languages (Python or TypeScript) - or proof that you can learn what's needed.\n\nExperience building and shipping AI products end-to-end (at a startup, on a side project, in open source, or at scale in a larger company).\n\nComfort working across the stack - frontend, backend, infrastructure. You are everywhere.\n\nAbility to work directly with customers or non-technical stakeholders to scope, negotiate, and deliver solutions.\n\nA track record that shows drive: maybe you’ve launched something on your own, contributed to open source, or taken ownership of hairy projects others avoided.\n\nBonus if you have:\nEarly-stage startup experience, especially in AI, voice platforms, or event-driven systems.\n\nFamiliarity with modern cloud infrastructure (Kubernetes, serverless, distributed systems).\n\nEvidence of customer empathy - support experience, founder experience, or just building things that solved real user pain.\n\nPerks & Benefits\nCompetitive salary & equity - we are building together, we win together\n\nWellhub Gold subscription - access 1000's of gyms and health related activities (inc. GymBox, 1Rebel, F45 etc)\n\nAI-focused learning & development - stay ahead of the curve.\n\nTeam socials & annual offsites - cool destinations included (last year we went to Greece!).\n\nPrivate healthcare - because your well-being matters.","description_format":"text","description_chars":3818,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Conversational AI","AI Agents","Field Service Management Software"],"lifecycle":[{"event":"open","at":"2026-07-30T15:10:35Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.342,"p_room":0.28,"age_days":77,"expected_fill_days":28,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/elyos-ai-founding-engineer","json_url":"https://alion.io/job/elyos-ai-founding-engineer.json","meta":{"generated_at":"2026-10-16T22:11:13Z","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":3629,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":7704},"rest":"https://alion.io/mcp/rest/get_company?id=7704"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Felyos-ai-founding-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%2Felyos-ai-founding-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%2Felyos-ai-founding-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/elyos-ai-founding-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Felyos-ai-founding-engineer"}]}
