About Asterix

We’re solving the biggest problem in healthcare: The shortage of highly-qualified doctors.

Millions of patients wait weeks for appointments. Millions more are stuck on hospital waitlists. Preventable conditions are missed and go unnoticed. You know this is a societal problem.

Asterix is building the only scalable solution: a new model of care where highly-qualified doctors are augmented by best-in-class technology to make safer, more consistent clinical decisions.

Our DoctorOS platform is becoming the backbone of modern healthcare delivery. We combine rigorous clinical leadership, real-world healthcare workflows, and AI tooling that makes doctors 10x more productive.

We’re backed by Entrepreneur First, have recently closed an oversubscribed funding round, and are live with some of the largest healthcare providers in the UK generating revenue and scaling fast.

Your mission at Asterix

Your role will be to help us safely deploy AI in healthcare. This means owning the infrastructure to monitor, building and maintaining LLM evaluation pipelines, designing clinical document processing systems and working with NHS data integrations. We want to tackle the thorniest problem in healthcare that most shy away from: clinical work.

This role is backend focused. We want you to be able to optimise, scale and own our core backend services end-to-end. This includes designing APIs and data models, to building reliable AWS‑based systems with strong observability and security, and integrating with NHS data sources as we grow.

From day one, you will build software used by doctors to deliver patient care every single day. You're expected to own code, deploy to prod on your first day, solving problems end-to-end. From scaling infra to hiring the next teammate and jumping on customer calls, you do what needs doing.

Who you are

You know our stack

Our stack is built for speed, reliability, and shipping fast in a regulated space.

💻 React + TypeScript on the frontend Vite, Tailwind, shadcn/ui, React Router 7, Vitest, Playwright, Biome. Clean, accessible, and well-tested.

☁️ Supabase for storage. AWS on the backend. Lambda, API Gateway, S3, SQS, DynamoDB, EventBridge, CloudWatch, SNS, Secrets Manager, SSM. Deployed with SAM and bash scripts. Simple, composable, no over-engineering.

Our culture: The Asterix way

Humble — We assume we're wrong until the data or a clinician proves otherwise. Curiosity over ego, always.

High-intensity, founder mentality — You don't wait for permission. You push problems to resolution. You act like an owner of the mission, the systems, and the culture. Solving one of society's biggest problems won't happen in a 9-to-5. We work hard, with purpose.

Joyful energy — We take the work seriously — not ourselves. We celebrate progress, support each other, and keep the energy high.

In-person by design — We work shoulder-to-shoulder in London. It makes us faster, tighter, and better.

We're an early-stage company with massive ambition. We need real commitment and dedication. The pace here is fast, with ambitious delivery targets. You will thrive if this excites you, but if you are at the stage of your career where you want a traditional 9-to-5 this role is not for you.
