Full-Stack Engineer | Sydney | Base plus equity | Senior - Staff level, Data-Heavy Product, React, Python, 3D Data/Mapping

An early-stage AI company in Sydney needs a full-stack engineer to make a data-heavy product fast, clear and enjoyable to use.

The company

The product helps engineering teams make sense of large volumes of operational data from machines, with customers using it daily. Small senior team, live customers and backing from leading investors.

The role

You’ll own whole areas of the product, from deciding what to build through to shipping it and improving it. Most of the challenge is in the browser: showing a lot of data at once in ways people can understand, and keeping it rapid as the data grows. You’ll work across the stack when a feature needs it, and your work reaches real users within days.

What you’ll do
Design, build and ship product features end to end
Build interfaces that combine spatial views, charts over time, maps and dashboards, and work well on mobile
Find out why pages are slow and fix the underlying cause




Raise the standard of front-end work across the team
Write the APIs, data models and background jobs a feature needs

What you bring
Experienced in building production web products, front end and back end
Solid React and TypeScript, and solid CSS
Positive product judgement: you can make sensible design decisions without a mock-up for every case
Experience making data-heavy pages fast
Comfort with a Python back end, or a quick learner on one
A habit of shipping often and owning the result

Nice to have
Visualisation-heavy products, including 3D, mapping or charting libraries
Experience building or maintaining a design system
Fluency with AI coding tools
Interest in hardware, IoT or industrial systems

What’s on offer

A competitive base plus meaningful equity, a small senior team with no layers, and an inner-Sydney office with one flexible day a week.
