Join a senior backend engineering team responsible for designing and delivering reliable systems used by a large consumer-facing application. You will own critical backend components, design and evolve APIs, make data-modeling decisions, optimize database queries, and build well-tested background processing. The role requires independent judgment and strong attention to correctness, performance, and reliability.
Highlights
Senior backend ownership with responsibility for critical production systems and technically important data flows. The role emphasizes architecture, API evolution, database performance, correctness, reliability, and independent technical decision-making.
Description
The roleYou will lead the design and delivery of backend systems for a consumer sports app used by real customers with real money on the line.
You will own significant parts of the backend end to end.
This is a senior role.
We expect you to take ambiguous problems and turn them into well-designed, well-tested systems with little direction, to make sound technical decisions and explain the tradeoffs behind them, and to raise the bar for the engineers around you.
What you will doLead the technical design of new backend systems and major features.Own critical parts of the backend, including the paths where money moves, and be accountable for their correctness, performance and reliability.Design and evolve the APIs our mobile and web clients depend on, keeping them consistent and backward compatible as the product changes.Make data-modelling decisions, and write schema changes and queries that stay correct and fast under production load.Build background and scheduled processing that is reliable, retries safely and never does the same work twice.Build and scale realtime features that push live updates to clients.Integrate with third-party services and data providers, and design for their failures.Lead the response to production incidents, find the root cause, and make sure the same failure cannot happen again.Set the standard for testing and code quality.
Review code and designs thoroughly.Work directly with product, mobile and web to shape what we build, not only how.Who we are looking for6 or more years of professional backend engineering, with deep production experience in all of the following:
TypeScript and Node.jsNestJSgRPC and Protocol BuffersGoPostgreSQL and TypeORMMongoDBRedis and BullMQWebSockets with Socket.IODocker and KubernetesGoogle CloudJest, and a track record of building well-tested systems
You have designed and run distributed backend systems in production and have owned them through growth, incidents and change.
You reason confidently about transactions, concurrency, idempotency and failure modes, and you can diagnose a slow query, a stuck queue or a failing rollout under pressure.
You have worked on systems where correctness is not optional, such as payments, ledgers or other financial flows.
You write clearly, make decisions you can defend, and make the engineers around you better.
