**Who’s a good fit?**

*   **Takes full ownership** – accountable for uptime, code quality and delivery; jumps into any fire.
*   **Resourceful problem‑solver** – thrives solo today, comfortable leading a small squad tomorrow.
*   **Commercial thinker** – talks retention curves and gross margin as fluently as GraphQL resolvers.
*   **Product shaper** – doesn’t just build what’s specced; shapes the solution by understanding the customer problem, exploring trade-offs, and simplifying complexity.
*   **Challenges & asks why** – healthy debate with leadership; hunts for real bottlenecks.
*   **AI‑obsessed tinkerer** – plays with every major model release and lives in AI‑native IDEs (Cursor, Codex, Orchestrator, Claude Code…).
*   **Full‑stack bias toward action** – React/React Native, Python/Django, GraphQL, Postgres, AWS (or the conviction you can master them fast).
*   **Ops‑literate** – IaC, CI/CD, observability; can chase a latency spike from CloudFront to EXPLAIN.
*   **Mentor & multiplier** – drafts crisp guidelines, reviews for clarity, and grows those around you.

**Why Join Us?**

*   **Scale what’s already working** – we’re profitable, loved by customers, and early in our growth curve.
*   **Own meaningful upside** – up to **A$250 k salary + attractive ESOP**.
*   **Green‑field AI projects** – build novel consumer wine experiences no one else is shipping.
*   **Joyful, adventurous culture** – we ditch wine snobbery for inclusive, curiosity‑fuelled service every time.
