Senior Full-Stack Engineer (React, Python, 3D Data)

About the role

An early-stage AI company in Sydney is looking for a full-stack engineer to build a data-heavy product quickly, clearly and enjoyably. The product helps engineering teams understand large volumes of operational data from machines, with customers using it daily. You will own whole areas of the product, from deciding what to build to shipping and improving it, mostly in the browser while keeping performance fast as data grows.

Key responsibilities

• Design, build and ship product features end to end.
• Build interfaces combining spatial views, charts over time, maps and dashboards, working well on mobile.
• Diagnose 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.

Required profile

• Experience building production web products, front end and back end.
• Good product judgement: sensible design decisions without a mock-up for every case.
• Experience making data-heavy pages fast.
• Habit of shipping often and owning the result.
• Nice to have: experience with visualisation-heavy products (3D, mapping, charting), a design system, fluency with AI coding tools, and interest in hardware, IoT or industrial systems.

Required skills

• Strong React and TypeScript, and solid CSS.
• Comfort with a Python backend, or a quick learner on one.

What we offer

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