Graduate Full Stack Developer (Backend)

Perkx is building a new app and is preparing for launch. The role focuses on backend development with Postgres and serverless functions, with occasional work on Flutter apps. The company offers a high-impact startup environment with mentorship for graduates.

• Handle Stripe subscriptions end-to-end—trials, plan changes, cancellations, resumes, and the webhooks that keep our database honest about all of it.
• Build jobs that run on a clock, state machines with deadlines, and tackle the concurrency problems that come with both.
• Write schema and migrations, implement row-level security (RLS) policies, and write the Postgres functions that hold our business rules.
• Connect with payment, email, and push-notification providers, including the unglamorous but critical work of making webhooks 100% reliable.
• Build aggregation jobs powering the live reporting that our business clients see in their dashboards.

• A degree in Computer Science, Software Engineering, IT, or similar—OR a portfolio of things you've actually built and shipped.
• Real SQL Ability: You can confidently write a multi-table join with aggregation, and you understand exactly why a transaction and an index exist.
• Working knowledge of TypeScript or JavaScript—enough to write and debug a server-side function from day one.
• You can explain your technical reasoning clearly and concisely in writing.
• You care deeply about correctness.

• Launch Experience: Be part of the foundational team pushing a fresh app out to the wild.
• Rapid Career Growth: You will learn more in 6 months here than in 2 years at a massive corporate graduate assembly line.
• Prime Sydney Location: Work onsite alongside a passionate, collaborative team right here in Sydney.
• Modern Tech Stack: Work with cutting-edge tools like Flutter, Postgres, and Serverless tech.
