Technical Lead

Careers at Paper.id; Jakarta Pusat; On-site; IDR 600,000,000 - 1,200,000,000; Full time

Job summary

Paper.id, a Bank Indonesia-licensed payment service provider, is seeking a software engineering lead to own the tech direction for a unit, including Go microservices, a modern SPA frontend, and production data stores. You will mentor engineers, own production services and on-call duties, and drive reliability, performance and security as continuous practice.

The role requires 5+ years shipping production software, 2+ years leading a team, deep Go, Angular/React/Vue expertise, and strong MySQL

Qualifications

• 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

Responsibilities

• 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
