About the role
About Elyos AI
We’re building the next generation of customer service with AI Agents. 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.
We 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.
At 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.
What You’ll Do
Build and ship core product features across our stack (Python, TypeScript, cloud infra, event-driven systems, third party integrations).
Own the lifecycle: work directly with customers to understand their needs, scope solutions, and deliver outcomes.
Move fast, when it matters: know when to hack an MVP to deliver value quickly, and when to invest in scalable foundations.
Raise the bar: use best practices everywhere (e.g testing, documentation, reliability, security) and help others do the same.
Who You Are
Customer-obsessed: You start with the customer. You empathise with their needs, ask the right questions, and build with their success in mind.
Biased for action: You try stuff. You move quickly, experiment often, and aren’t afraid to learn in public.
