Job description
My London based client is urgently looking for an experienced Lead Software Engineer with a strong Back End focus to lead the build and evolution of scalable, cloud-native services. You'll set technical direction, mentor engineers, and stay hands-on delivering production code.
What you'll do:
- Lead Back End design and development (Node.js, TypeScript/JavaScript)
- Build and operate event-driven microservices using Kafka
- Own AWS-based delivery (scalability, performance, reliability, security)
- Drive engineering standards: code reviews, testing strategy, CI/CD, observability
- Partner with Product/Architecture to translate requirements into robust solutions
Requirements
- Strong commercial Back End experience with JavaScript/TypeScript (Node.js)
- Kafka experience (event-driven systems, distributed messaging)
- Strong AWS experience across modern cloud services
- Microservices/distributed systems design + production operations mindset
- Proven technical leadership (mentoring, guiding delivery, owning outcomes)
Nice to have:
- Containerisation (Docker/Kubernetes/ECS)
- Infrastructure as Code (Terraform/CloudFormation)
- Observability tooling (eg, CloudWatch/Datadog) and CI/CD (eg, GitHub Actions)
