Job description

Lupa is building a category defining product the industry has never seen before.

We're the AI-native operating system for veterinary practices and pet parents, replacing the fragmented, clunky systems vets have tolerated for years with a single intelligent platform for scheduling, client communication, clinical documentation, and AI-driven care guidance. Practices run more efficiently, vets get back to doing what they love, and pet parents feel more connected to their animals' health than ever.

The traction speaks for itself: founded in 2023 and already one of Europe's top 100 AI startups, with a team of 70 people, 10x growth in twelve months, the UK market leader, and now charging hard into the US and Europe. We have $25M in funding, 2.5M+ pets on the platform, and a buzzing HQ in Paddington, London. We've attracted exceptional people from the likes of Palantir, Google, DeepMind, BCG, Meta, and AWS and we're just getting started.

This is a rare chance to join a rocket ship at exactly the right moment and we're looking for exceptional people to help us fly it.

In this role, you will:

• Own features end-to-end across the full stack (you could be leaning either frontend or backend), from API design to React interfaces to database migrations

• Ship real, user-facing product that reaches vets and pet owners every single day

• Help shape how the engineering team works as we scale.. Early hires leave fingerprints here

• Collaborate closely with product and design, moving fast and debating well

• Take on real ownership and responsibility from day one: no lanes, no waiting

Your background looks something like:

• Engineering experience in tech and product-driven environments

• Strong, practical command of TypeScript, Node.js, React, and PostgreSQL

• A genuine track record of shipping user-facing features at pace in a startup or high-growth environment

• Experience at a Series A/B startup, high-throughput B2B SaaS, or consumer tech business

• Familiarity with Terraform, Docker, AWS, or GitHub CI/CD

As a person, you:

• Get restless when you can't see the whole problem and love owning it end-to-end

• Take genuine pride in what you ship, and care about what users actually experience

• Can take an ambiguous brief, ask the right questions, and make smart calls without constant direction

• Are excited to work in-person from our Paddington, London HQ (Hybrid)

• Thrive in a fast-moving environment where the priorities are real and the pace is relentless

What does success look like in 6 months?

• You are shipping independently, scoping and building features that users love without needing to be unblocked at every step.

• You have built real trust with the team by being humble, direct, and dependable.

• People come to you not just to get things done but because they want your input on problems that are still half-formed.
