- Using Redis for caching, queueing or rate limiting.
- Contributing to architecture, technical documentation and engineering standards.
- Owning features through development, testing, deployment and production support.
- Supporting the existing platform as the business transitions to its next-generation product.
- Diagnosing production incidents and participating in an on-call rota.
What we’re looking for
- Substantial commercial TypeScript experience across backend and frontend development.
- Strong Node.js experience, including designing and maintaining production APIs.
- Experience with high-volume, real-time or event-driven systems.
- Experience working with large datasets, ideally 100 million+ datapoints.
- Practical MongoDB experience covering schema design, indexing, aggregation and performance troubleshooting.
- Commercial experience with Redis.
- Evidence of owning production systems, including reliability, monitoring and incident resolution.
