Job description

This is one of the most interesting companies we have ever seen and THE biggest VCs in the US think so too.

This venture-backed startup is building a new kind of marketplace for collectables. It combines the thrill of opening a pack with full transparency: published odds, live market pricing and results nobody can change after purchase.

It launched to an invite-only community a month ago and has already processed thousands of sales and six-figure transaction volume, with some of the worlds biggest trading card sellers already on board. The longer-term goal is trusted infrastructure for pricing, storing and trading collectables (art, watches, cars) as a genuine asset class.

The role

You'll be the first and sole Frontend engineering hire, owning everything users see and touch. The goal is a marketplace that never lags, a reveal that feels instant and numbers users understand at a glance.

You'll work directly with the technical co-founder (quant background, product, backend and pricing), alongside a motion designer and a design agency. You'll set the frontend architecture, ship every week and kick-start the mobile app.

What you'll work on

• The reveal: making a server-decided outcome feel instant, with motion, suspense and sound


• The catalogue: thousands of high-resolution card images that load fast on a mid-range phone


• Live pricing: market prices and odds updating in real time, plus portfolio charts


• Money flows: checkout, buyback and payouts that never show a wrong number


• Seller tools: a pack builder that power users live in


• Mobile: a design system that carries through to a cross-platform app


• AI: tooling and agents built into how the team builds

About you

• You live frontend: deep TypeScript and React, and you go deep rather than wide


• You have an eye for design and notice a dropped frame or an off colour before anyone else


• You've built consumer products, marketplaces or live commerce where the details matter


• You measure performance: profiling, testing and load testing, with numbers before and after


• You have a portfolio or work you can show


• You ship fast without dropping quality, and you think about what could go wrong for the customer


• You use AI heavily and thoughtfully. It does your typing, not your thinking.

*Trajectory matters more than years of experience. If you learn fast, set ambitious targets and hold strong opinions loosely, we want to hear from you.

What's on offer

• Base salary of <$200k plus super


• Milestone bonuses of up to $100k, in cash or equity, paid each time the company hits a milestone (which is already frequent) rather than annually


• Up to 5% equity (four-year vesting, one-year cliff), for a total initial package of up to $500k a year


• A founding role with no layers above you, and a path to the board by invitation


• In person in Sydney or Melbourne, with domestic and international relocation and visa sponsorship available


• The option to move when the company expands to the US (New York)


• Fully catered food, 2-3 team offsites a year
