About The Position

Build systems, not just services. Work across products, not inside one codebase. Own problems from first question to production. The role We run a portfolio of mobile products used by millions of people. Our engineering team works across that portfolio. You won't join a permanent team attached to one app. You might spend your first few weeks improving the backend of one product because that's where the biggest technical need is. A month later, you could be designing a service for another, helping resolve a production incident elsewhere, or improving infrastructure used across several products. That's intentional. We want engineers who can understand a system quickly, find the real problem, and move between different technical contexts without needing everything to stay familiar. We're looking for a Senior Backend Engineer who combines depth in backend engineering with breadth across systems, infrastructure, architecture, and product. Think T-shaped : deep in backend engineering, broad enough to understand the systems around it.

Requirements

• 5+ years of backend engineering experience (number matters less than what you've owned).
• Ability to design or significantly change a backend system.
• Experience making architectural decisions and explaining trade-offs.
• Experience working with databases beyond using an ORM.
• Experience operating and debugging services in production.
• Understanding of infrastructure rather than treating it as a black box.
• Ability to take work from an unclear problem to a shipped result.
• Ability to learn new technology when needed.
• Production experience with Go is useful, or strong backend experience in another language plus evidence of learning new stacks quickly.
• Ability to become productive in Go and not treat one language as a professional identity.
• Understanding of relational databases, schema design, migrations, indexing, and query behavior.
• Understanding of distributed systems, message queues, and brokers such as Kafka.
• Understanding of Docker and Kubernetes.
• Understanding of cloud infrastructure and APIs.
• Understanding of observability, performance, reliability, and failure modes.

Nice To Haves

• Production experience with Go is useful.
• Strong backend experience in another language plus evidence that you learn new stacks quickly can work too.

Responsibilities

• Design, build, run, and improve backend systems across multiple products.
• Take problems from an unclear starting point through architecture, implementation, deployment, and iteration.
• Investigate systems you didn't build.
• Work directly with product, frontend, data, and other engineers.
• Improve existing systems instead of assuming everything needs a rewrite.
• Help solve problems when they arise, even if they weren't part of the original plan.

Benefits

• We are remote-first and work across countries and time zones.
• We document decisions, communicate directly, and care about outcomes more than visible activity.
• Priorities can change when new information appears.
• A production issue can become more important than yesterday's plan.
• We expect people to understand the new context, adjust, and keep moving.
• We strongly encourage applicants of all backgrounds.
• We consider all candidates regardless of age, ethnicity, religion, sex, sexual orientation, gender identity, family or parental status, national origin, veteran status, neurodiversity, or disability.
• If you need reasonable adjustments at any point in the application or interview process, please let us know.
