Technical Lead

Paper.id is a Bank Indonesia-licensed payment service provider. Each of our business units owns its product end to end - Angular web, Flutter mobile, Go services and the data underneath. You’ll lead one of them.

What you’ll do

• Own technical direction for your unit: architecture, service boundaries, data modelling - and the written reasoning behind each call
• Ship predictably at a quality bar you set, partnering with Product on the roadmap rather than taking orders from it
• Mentor and grow your engineers; give structured input into performance reviews (compensation and headcount sit with the EM and VP)
• Own your services in production - deploy, monitor, respond to incidents, write the postmortem. Leads join the on-call rotation
• Treat reliability, performance and security as continuous work, not scheduled projects
• Interview and calibrate for your own squad

What we’re looking for

Must have

• 5+ years shipping production software, including 2+ years leading a team
• Depth in Go microservices, async messaging, and a real grasp of eventual vs. strong consistency
• Productive in a modern FE & SPA framework - Angular, React or Vue
• Strong MySQL: schema design, indexing, query performance, migrations on large tables. Plus a document or graph store in production, or clear evidence you pick up new data stores fast - we run ArangoDB across a dozen services
• Mobile literacy to lead: review Flutter PRs, reason about release trains, and spot an API change that breaks app versions already on people’s phones. Able to write Flutter code is a bonus
• Cloud and production ownership - you’ve been on the hook when your services broke
• Bias for action. You make technical calls with incomplete information, commit to them, and own the outcome - rather than waiting for consensus or escalating decisions that are yours to make

Nice to have

• Hands-on Flutter/BLoC
• Graph data modelling
• Payments or another regulated domain (QRIS, virtual accounts, e-wallets)
• Previous B2B/SaaS experience

Stacks

Angular 19 + NgRx · Flutter (BLoC, Firebase) · Go 1.21+ clean architecture · PHP (Lumen) · MySQL, ArangoDB, Redis · GCP, AWS, Kubernetes, New Relic
