Senior Backend Engineer

Annual releases gave way to two-week sprints years ago, and the platform now handles over 200 million API calls a day. We started in 1992 and have grown to about 4,100 people. We keep recurring meetings to Tuesdays and Thursdays where we can.

Role overview:

Canopycast is hiring a Senior Backend Engineer for our London location. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. Hybrid, with three days a week in our London office.

What you'll be doing:

• Handle on-call for services the team owns and lead incident follow-ups
• Add caching with Redis where it actually helps, and remove it where it doesn't
• Model data and write migrations for PostgreSQL, MySQL or DynamoDB
• Write integration and contract tests so API changes don't break consumers
• Document APIs in OpenAPI and keep the docs current
• Review code for correctness, performance and failure handling
• Coordinate with frontend and mobile engineers on API contracts and versioning

What you need:

• 5+ years of backend development experience in a production environment
• Working knowledge of message queues or streaming platforms
• Clear written communication, including design docs
• Familiarity with Docker and CI/CD pipelines
• Understanding of concurrency, transactions, idempotency and retries
• Hands-on experience with AWS, GCP or Azure services
• Strong SQL and relational data modelling skills

Preferred qualifications:

• Kubernetes, including Helm charts
• Terraform or Pulumi
• Prior work breaking up a monolith

Salary: £95,000 - £130,000 per annum

Why work with us:

• Private medical insurance
• Company pension
• 28 days annual leave including bank holidays

Unfortunately we cannot offer visa sponsorship for this role.

Start: Within 30 days.
