Job Title: Senior Developer
Duration: 6 months
Location: Osterley
Interview Process: 2 rounds
Job Description
Join our team responsible for building and maintaining high-scale OTT SaaS platforms. You will work on robust TypeScript/Node.js backends, GraphQL APIs, and cloud-native deployments (Helm, Kubernetes), contributing to resilient, well-tested business logic and infrastructure.
What you’ll do:
Architect, develop, and maintain scalable TypeScript/Node.js services and GraphQL APIs.
Write resilient, maintainable code with a strong focus on automated testing (unit, integration, functional, end-to-end, visual regression, Lighthouse).
Collaborate on DevOps practices: CI/CD (Jenkins, Concourse), containerisation, Helm chart authoring, and Kubernetes deployments.
Work within a cross-functional Agile team, contributing to technical direction, code reviews, and process improvements.
Ensure code is performant, secure, observable, and aligned with best practices.
Mentor and support junior developers, fostering a culture of technical excellence.
What you’ll bring:
Extensive experience with TypeScript and Node.js in production environments.
Strong knowledge of GraphQL (API design, schema evolution, integration).
Experience with automated testing frameworks (Vitest, Playwright, Jest).
Familiarity with DevOps tooling: Docker, Helm, Kubernetes, CI/CD pipelines.
Experience with cloud-native architectures and infrastructure-as-code.
Ability to drive improvements across the codebase and influence technical direction.
Experience mentoring and coaching developers.
Bonus: Experience with YAML, Helm chart templating, and large-scale SaaS or OTT platforms
