Job description

Senior Software Engineer, Backend - Business Platform

We're looking for a Senior Backend Engineer to join our Business Platform team in Jakarta, Indonesia. The Business Platform powers the backend capabilities that enable businesses and enterprises to onboard, operate, grow, and serve consumers at scale across Southeast Asia.

Get to Know the Role

In this role, you will design, build, and evolve backend platform services that manage business profiles, store metadata, business configuration, and related operational workflows. You'll work on systems that sit close to the source of truth for business data and workflows—systems that directly influence how businesses set up their operations, how internal teams operate reliably, and how downstream products consume trusted business information. The ideal candidate will demonstrate strong ownership, system design thinking, and a commitment to building platforms that simplify complexity rather than spread it around. This is an onsite role based in Jakarta.

The Critical Tasks You Will Perform

• Lead the architectural design of microservices, high-throughput APIs, and data storage solutions built to handle scale and high availability.
• Diagnose high-stakes performance bottlenecks, refactor core infrastructure, and ensure low latency across distributed systems.
• Own end-to-end delivery of mission-critical systems—from writing technical design documents (TDDs) and scoping projects to deploying and maintaining production features.
• Drive code quality across the team through high-bar code reviews, system reliability standards, and technical mentorship of mid/junior engineers.
• Oversee cloud infrastructure (AWS/GCP/Azure), automated CI/CD pipelines, security protocols, and robust incident management/observability to guarantee strict SLAs.
