About the role:
As a Senior Backend Engineer, you’ll own features end to end, from design and decomposition to delivery in production. You’ll architect robust Go services within a distributed system: scaling databases, syncing data across devices, building integrations with other services (e.g., calendars), and optimising the performance of critical components. AI-assisted development is now a natural part of our workflow, giving you the reach to work across many parts of the product.
What you’ll do:
- Own features end to end: design, decompose, estimate, coordinate with teammates, and ship to production
- Build and evolve Go services that handle sync, integrations, and data processing at scale
- Optimise queries and data access on large MySQL tables, and design async processing flows
- Keep the system healthy: investigate alerts, dig into logs in Kibana, metrics in Grafana, and pods in Kubernetes
- Test your own changes before they reach users, and review code in backend repositories
- Contribute to the frontend parts of your features (desktop and iOS clients), using AI agents to work efficiently across the stack
- You’ll start with backend only and gradually take on client-side work as you get to know the product
About you:
- Solid Go experience with strong hands-on coding
- Experience building large features with full ownership, from idea to production
- Strong knowledge of database optimisation (indexing, query tuning, working with large tables)
- Experience with async processing and distributed systems: queues, retries, failure handling, consistency
- Practical Kubernetes experience: deploying, debugging, investigating issues
- Confidence using AI coding tools, and the judgment to review and verify what they produce
- Some experience with any frontend technology, and readiness to contribute to client-side code when a feature requires it
