Lead Applied AI engineer

You’re an exceptional applied AI builder who wants a lot of ownership.

You’ve probably spent the last few years building with modern ML and LLMs and have gone much deeper than plugging an API into a product.

This might look like:

3+ years building and shipping ML or AI systems in production

Strong experience with modern LLMs and applied AI systems

Deep understanding of evals – how to construct them, measure model quality and use failures to drive improvement

Experience with post-training, fine-tuning, RAG, structured outputs, tool use or similar techniques

Strong instincts around training data – what data matters, how to structure it and how to improve its quality

Enough engineering ability to take an idea from experiment to production

Good judgement about when to use a frontier model, an open-source model, retrieval, fine-tuning or something simpler

Strong product thinking – you care what the system enables for the user, not just the benchmark score

Comfortable working directly with domain experts to turn human expertise into data, evals and model behaviour

Experience in health, veterinary care or insurance is useful. It isn’t required.

A PhD isn’t required either. We care much more about what you’ve built, how you think and how quickly you learn.

You’re all in on AI and believe it can make the world meaningfully better

A new model drops and your first instinct is to try it

You’re optimistic about where the technology is going and curious about what becomes possible next

You’re empirical – you test things rather than arguing about them in theory

You move quickly and like turning experiments into real products

You’re brave enough to try approaches that might fail

You want a huge amount of influence over product and technical direction

You want to build the capability yourself before building a team around it

You like working with very smart people from different disciplines

You love pets 💗

You want to spend most of your time managing rather than building

You need a research paper before you’re comfortable trying something

You think your job ends when a model works in a notebook

You’re attached to one model, vendor or technical approach

You prefer long research cycles over shipping, measuring and iterating

You need a defined roadmap handed to you

You want everyone to stay neatly inside their lane

The Fetch team is ambitious, smart, hard-working, thoughtful and kind.

You’ll work directly with the founders and be involved early in product and company strategy.

We build our own platform and products, so there are very few layers between an idea and something being used in the real world.

You’ll have access to proprietary pet health data, vets and vet nurses who deeply understand the domain, and an engineering team that can help turn models into products.

We use AI constantly ourselves. New tools, models and ideas are there to be tried rather than put through months of approvals.

And you’ll be working on something that matters – eventually helping millions of pets live healthier, happier lives.
