Job Description

n

Fetch is how modern pet parents give their pets the best care. One pink app for insurance, health and care.

n

We’ve raised our Series A from Lightspeed and Airtree, we’re rated 4.9 on Google, #1 by CHOICE, and we’re growing fast.

n

We think AI is going to fundamentally change how we care for pets.

n

We have pet health data, an in-house team of vets and vet nurses, and we build our own product and technology. We want to turn that into an intelligence layer that understands each pet deeply – their history, health and what might matter next.

The role n

This is a senior, hands-on builder role.

n

You’ll lead applied AI at Fetch – setting the direction, choosing the models and approaches, building them yourself, measuring whether they actually work, and shipping them into real products.

n

Your core job is simple: make Fetch exceptionally good at understanding pet health.

n

That capability will power everything from helping pet parents care for their pets, to supporting vets, interpreting health records and automating parts of insurance.

n

We don’t need someone with a particular academic pedigree. We want someone who is obsessed with what modern models can do, moves quickly, experiments constantly and knows how to turn new capabilities into reliable products.

Location: n

Sydney, hybrid, 3 days in office

Employment type: n

Full time

Compensation: n

Series A salary + meaningful equity

Working with: n

Co-founders, engineering, product, data, vets and vet nurses. We’re flat, fast and care about the best idea.

What you’ll build and own Fetch’s pet health intelligence layer: n

models and systems that can understand messy, longitudinal pet health information and reason over it

Model quality end-to-end: n

datasets, evals, model selection, prompting, retrieval, post-training, fine-tuning, guardrails and monitoring

A serious evaluation system: n

clear benchmarks for what good looks like, where models fail and whether a new model is actually better

Domain-specific AI: n

turning proprietary pet health data and expert veterinary knowledge into capabilities generic models don’t have

Multimodal understanding: n

health records, documents, images and, over time, richer inputs like video

Safe production AI: n

working closely with our vets, compliance and engineering teams to make sure the systems we ship are reliable and clinically appropriate





The next generation of Fetch products: n

you’ll be deeply involved in product direction and help decide what we should build with AI, not simply implement someone else’s roadmap

The beginnings of an exceptional AI team: n

this is a core capability for Fetch and we expect the team around it to grow

n

You’ll use whatever approach works best.

n

Sometimes that will mean a frontier closed-source model. Sometimes an open-source model. Sometimes RAG, tools or better context. Sometimes fine-tuning or post-training.

n

We care about getting to the best result, measuring it properly and improving it quickly.

About you n

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

n

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.

n

This might look like:

n

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

n

Strong experience with modern LLMs and applied AI systems

n

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

n

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

n

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

n

Enough engineering ability to take an idea from experiment to production

n

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

n

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

n

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

n

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

n

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

You’ll probably love this role if: n





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

n

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

n

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

n

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

n

You move quickly and like turning experiments into real products

n

You’re brave enough to try approaches that might fail

n

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

n

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

n

You like working with very smart people from different disciplines

n

You love pets

You probably won’t love this role if: n

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

n

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

n

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

n

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

n

You prefer long research cycles over shipping, measuring and iterating

n

You need a defined roadmap handed to you

n

You want everyone to stay neatly inside their lane

What it’s like here n

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

n

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

n

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

n

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.

n

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

n

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

n

Competitive Series A salary + meaningful equity

n

Hybrid working – 3 days Sydney office, flexible WFH

n

Latest MacBook Pro and a top setup

n

Unlimited AI tooling – if it helps you build, use it

n

Two team retreats each year

n

Office dogs for cuddles and interruptions

n

Bean-to-cup coffee, unlimited fruit and snacks. Toblerone on tap

n

Inclusive parental leave

n

5 weeks annual leave
