Lead Software Engineer

Responsibilities:

• End-to-end feature ownership: Design, build and ship complete features across frontend, backend and database, from system design to production deployment.
• Full-stack development: Build and maintain high-performance, responsive applications using React.js, Next.js, Node.js and NestJS.
• API and architecture design: Develop secure RESTful and GraphQL APIs, and lead the design of microservices and event-driven architecture.
• Database and caching: Design, optimise, and manage PostgreSQL databases, and implement Redis caching for peak performance.
• Asynchronous processing: Build event-driven pipelines using messaging queues such as Kafka or RabbitMQ.
• CI/CD: Build and maintain automated pipelines on GitHub Actions with testing, security scanning and rollback for zero-downtime releases.
• Containers and Kubernetes: Containerise applications with Docker, and own their deployment and scaling on Kubernetes.
• Infrastructure as code: Provision and evolve AWS infrastructure using Terraform, keeping environments consistent and repeatable.
• Observability and reliability: Set up monitoring, logging, and alerting with tools such as Prometheus, Grafana, ELK, or Datadog, and lead root-cause analysis when things break.
• AI/ML integration: Work with AI/ML teams to integrate intelligent, automated services into production applications.
• Security and compliance: Enforce robust authentication, authorisation, data encryption and secrets management, in line with financial regulations and the ISO 27001 and PCI-DSS requirements of our BFSI clients.
• Code quality and mentoring: Write clean, modular, well-tested code, review others' work, and mentor junior engineers.
• Documentation: Maintain clear design documents, architectural decision records (ADRs) and runbooks. Attributes
