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

Strong 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.
