You will be our first dedicated developer in Vietnam, building products used daily by our Australian staff, our clients and their accountants. The split is roughly 70% backend, 30% frontend.

• Backend (70%): build and extend REST APIs and services in Spring Boot (our codebase is Kotlin on Spring Boot; Java is fine, and strong backend developers from other stacks can cross over), PostgreSQL, and integrations with third-party APIs (CRM, email, documents).
• Frontend (30%): build and polish staff-facing, client-facing and accountant-facing surfaces (our app is React/Next.js; experience in any modern frontend framework transfers).
• Ship a complete, working product within your first 2 months, working side by side with our product analyst who writes the requirements. You are expected to question requirements that do not make sense, not just implement them.
• Familiarity with AI coding assistants (Cursor, Copilot, Claude) to boost productivity
• Push code continuously: staff use what you ship the same week and give feedback directly. We hold a high bar - small scope, polished, low-bug.
