Staff Engineer (Platform)

About BukuWarung

BukuWarung is building the financial and digital nervous system for millions of underserved merchants. Payments, credit, software, commerce, money management - all converging into one integrated platform.

We are not building features. We are building infrastructure that small businesses depend on to survive.

If you have ever wanted to design systems that matter at scale (not ad-tech dashboards, not incremental UI improvements) but real, high-volume, reliability-sensitive, multi-country platforms, this is that opportunity.

The Mission

We are entering a critical phase of growth. Velocity is improving. AI is accelerating development. But before acceleration, we need architectural depth.

We are looking for a Staff Engineer who cares deeply about

Designing systems that scale 10x and 100x

Failure domains and blast radius reduction

High availability and reliability engineering

Clean abstractions and long-term maintainability

Architecture that enables speed, not blocks it

What You Will Do

Lead architecture, design for high-scale systems across payments, EDC, credit, and merchant platforms

Design for multi-region expansion and high transaction volumes

Establish and elevate system design review standards

Drive platform thinking across squads

Identify scaling bottlenecks before they hurt

Reduce operational burden through thoughtful abstractions

Mentor engineers and grow them

You will work directly with engineering leadership and influence product decisions where system design matters.

What We’re Looking For

8+ years building and scaling backend distributed systems

Deep understanding of system design fundamentals (consistency models, caching strategies, event-driven architecture, fault tolerance, data modeling at scale)

Experience with microservices and/or modular monolith architectures

Hands-on expertise with cloud infrastructure (AWS preferred)

Strong intuition for performance tuning and observability

Comfort operating in ambiguity while raising engineering bar

Bonus Points

Experience in fintech or transaction-heavy platforms

Experience scaling systems across regions

Prior Staff/Principal-level impact in high-growth environments

What Makes This Role Different

At large tech companies, you optimize a slice of a mature system. Here, you will shape the spine.

Your decisions will influence how millions of merchants experience financial services. You will help define how engineering thinks about scale as a culture, not just as code.

If you are someone who

Thinks in systems, not just services

Gets uncomfortable when architecture feels fragile

Enjoys whiteboarding failure scenarios more than debating frameworks

Wants ownership beyond tickets

Then this role will stretch you.

If you’re excited by scale, complexity, and building something enduring, let’s talk.
