Full Stack Engineer

Brisbane, Australia (or remote AU) · Full time

Obsidian Collectables is a premium trading-card platform: storefront, mystery packs, and an escrow-protected marketplace. We’re a small operator-led team shipping a live product used by thousands of collectors.

The role

We’re hiring a senior full-stack engineer to help own the product as we scale. You’ll work across the existing platform and lead larger builds that involve messy real-world data, reliability, and user-facing product, not just ticket execution.

What you’ll do
Ship end-to-end features in a live Next.js / TypeScript codebase
Build and maintain data pipelines that ingest, clean, and store external and internal data on a schedule
Design systems where correctness matters (payments, balances, inventory, auditability)
Make product calls, not just implement specs
Raise the engineering bar as the company grows

What we’re looking for
Robust full-stack TypeScript: React, Next.js, Node, PostgreSQL




Experience building ETL / ingestion systems for messy real-world data
Comfort with time-series data, basic statistics, and turning noisy inputs into trustworthy product outputs
Product ownership mindset; you’ve shipped without needing a perfect brief
Experience near payments, ledgers, or other high-correctness systems

Nice to have
Charting / data visualization
Interest in collectables, trading, or markets
Early-stage / startup engineering experience
Prisma, Stripe, or NextAuth

Stack

Next.js, React, TypeScript, Tailwind, Prisma, PostgreSQL, NextAuth, Stripe, Vercel

About the team

Team of four. High ownership, low bureaucracy. You’ll work directly with the founder.

To apply, send a short note on something you’ve built that involved both product UI and messy data, plus your LinkedIn or GitHub.
