AI Product Builder

Who we are

Rethink AI is a consulting and product firm built to take organisations from AI curiosity to AI advantage. We don't just advise — we build.

Our anchor work has been with Rethink Group — parent to Rethink Investing, Australia's largest commercial buyer's agency, with more than $5.75 billion transacted over a decade in market. The group spans property, finance, legal, insurance, and renewables. We've shipped production AI systems now embedded in daily operations across the group, generating measurable business value.

Why this role exists

The hard part of building software isn't writing code anymore. It's judgment — choosing the right problem, designing a system that will survive production, catching the edge case before a user does.

We build software for high-stakes industries — property, finance, legal, insurance, education. Environments where getting it wrong is expensive.

We need a builder who treats AI as a collaborator, not just a tool. Who thinks about value first — then product, then architecture, then code. Who sees the difference between software that works and software people love to use — and can't stand shipping the first kind. Who's already building in their spare time because they can't stop.

You'll work directly with AI Principle Architect who cares about architecture, craft, and details. You'll leave having shipped production systems in a domain where few have. We will provide you with best tools in the market,

What you'll ship

• Features across the full stack, end to end

• Agentic AI systems that reason over complex business domains and improve through feedback loops

• Interfaces people love using, not tolerate

• Software with trackable, measurable business impact

We use a broad range of technology — AWS as the cloud provider, React on the frontend, Python or TypeScript on the backend. Or whatever AI wants to write that day.

What you'll get

• The best tools in the market — whatever helps you ship. Claude, Codex, whatever comes next.

• Coaching from a experienced team — real mentorship on architecture, product thinking, and craft. Who has been in the game for decades.

• Room to innovate — we're small enough that your ideas ship in days, we love ideas! Build, learn, iterate.

• Visible impact — your code lands in real production workflows. What you build gets used, measured, and iterated.

• Career acceleration — direct exposure to founders, clients, and the full business from day one. If you're early-career but already building at this level, there's no faster way to grow.

What we look for

Evidence that you build. Not because it's your job — because you can't stop. Show us what you've shipped. What you've made matters more than where you studied. Tell us your AI tool setup and what it's let you do.

Trajectory. What you built six months ago, you'd build differently today. Show us the arc.

The capabilities that actually matter:

• Product taste — you know whether something should be built, not just how

• UX craft — you see the difference between software that works and software people love. Interfaces, interactions, details. You notice them, and you push back when they're off.

• Architectural judgment — you see how data flows, how things fail, how they scale

• Detail and security — edge cases, failure modes, attack surfaces. First, not last.

• Tool leverage — you can structure a problem, direct an AI tool, and validate the output

• Clarity under ambiguity — you can shape a vague problem into a sensible plan

• Ownership — you define your own work and finish what you start

• Learning velocity — your practice evolves fast. If it hasn't changed in six months, we're probably not a fit.

This role isn't for you if

• You need tickets to know what to work on

• You see engineering as writing code, not building products

• UX and design feel like someone else's job

• You prefer large teams with clear swim lanes

• Your development process hasn't changed in six months

• Security and data integrity feel like someone else's problem

How we hire

We care about who you are as much as what you've built. Integrity matters. We start with a quick chat to get to know you — what you care about, what you're looking for — before we get into the technical side. When we do, we work through a real problem together with AI tools in the loop, because that's how we build.

Expect: intro chat, technical conversation, paid pair-build on a real problem, founder conversation.

How to apply

Send your CV and what you've built to careers@rethinkai.com.au — side projects, demos, live links, GitHub, whatever form it takes. If what you've built has a UI, share the live link so we can see how it feels.

A short note on what you're proudest of, what was hard, what you'd do differently, and your current AI tool setup.
