At Paper.id we're building the financial operating system for Indonesian businesses — invoicing, payments, and AR/AP that thousands of companies run their money through every day. The frontend is where that complexity has to feel effortless. We're looking for a frontend engineer who ships fast, cares about the whole system (not just the part they own), and treats AI as a core part of how they work — not a novelty.
This is a role for someone
hungry: curious enough to read the backend service behind the API they're calling, brave enough to open a Flutter file they've never seen, and honest enough to ask why are we building this before writing the code.
What You'll Do
- Build fast, reliable web experiences in Angular + TypeScript that talk to our RESTful microservices
- Write clean, tested, maintainable code — and care about loading time, bundle size, and edge cases, not just the happy path
- Use AI as a daily multiplier — code generation, review, debugging, test writing, spec drafting. We expect you to be genuinely good at this, and to help the team get better at it too
- Work shoulder-to-shoulder with Product and UI/UX to turn fuzzy requirements into features users actually understand
- Trace a bug or a feature across the stack — read the Go service, follow the API contract, and understand where the data really comes from before you patch the UI
- Contribute beyond the frontend when it helps ship — a backend fix / feature implementation, a Flutter mobile tweak, a script. We value people who fill gaps over people who guard boundaries
- Help refine specs and technical requirements — push back, ask questions, propose simpler approaches
- Keep quality and brand consistency high, and stay current on where frontend and AI tooling are heading
- Work in an agile team and take real ownership of what you deliver
What We're Looking For
- Strong fundamentals in HTML, CSS, JavaScript, and TypeScript
- Solid experience with a modern component framework — Angular 19 or above preferred; React or Vue experience transfers well
- Comfort consuming and reasoning about RESTful APIs and third-party libraries
- You use AI tools fluently and thoughtfully in your day-to-day engineering, and can talk about where they help and where they don't
- A genuine appetite to learn across the stack — backend, mobile, infra — and no fear of jumping into unfamiliar code
- Experience writing automated tests (unit + integration — Jest, Karma/Jasmine, Cypress, or similar)
- Comfortable with Git and collaborative, agile workflows
- Sharp problem-diagnosis instincts, creative under constraints, and a strong bias toward shipping and learning
Nice To Have
- Exposure to Flutter or another mobile framework
- Any backend experience — Go, Node, or building and consuming microservices
- Performance optimization work (bundle size, load time, rendering)
- A degree in Computer Science, Engineering, Mathematics, or a related field — but we care far more about what you can build and how fast you learn than about the diploma
