Senior Python Engineer | AI Engineering | Product Focused | Sydney

About the company

A fast growing, Series B AI scale up building AI agents that automate complex finance workflows for mid market and enterprise customers across Australia and the UK. AI is the product, not a feature bolted on, and their platform already processes over a million documents a month.

They have strong revenue growth, a highly technical founding team who still write code, and a small engineering team where every engineer has real ownership over what gets built.

The role

This is a product focused AI engineering role. You'll own features end to end, from understanding the customer problem through to designing agent workflows, shipping to production and measuring whether they actually work. You'll work closely with product, design and customers, and help shape the roadmap.

What you'll work on

Designing and building agent workflows in Python, including tool use, retrieval, retries and human handoff

Building evaluation frameworks so prompt and model changes are tested against real data before release

Deciding when a problem needs a frontier model, a smaller fine tuned model or plain code, based on cost, latency and accuracy

Building the review interfaces customers use when the agent needs a human in the loop





Talking directly to customers to understand where the product falls short

Python, FastAPI, Postgres with pgvector, Temporal, React and AWS, using frontier LLMs via API alongside smaller fine tuned models. You don't need experience across all of it. How you think and how quickly you learn matter more.

About you

5+ years commercial experience writing production Python, ideally in a product company

Have built and shipped at least one LLM powered feature used by real end users

Measure before you trust: comfortable writing evals and using data to make decisions

Product minded, comfortable owning work from scoping through to production

Enough frontend experience to contribute across the stack when needed

Transparent communicator who can explain technical tradeoffs to non technical people

Experience at a scaling startup is highly regarded, as is fintech or ERP integration experience

What's on offer

$190k to $230k + super depending on experience

Meaningful equity

Hybrid, 3 days a week in an inner Sydney office

Learning budget and generous API credits for experimentation

A short, practical interview process with no LeetCode
