Sr. Full Stack Engineer - (Node + React & Angular)

We are looking for an experienced Senior Full Stack Engineer with a strong backend engineering focus to design, build, and operate large-scale distributed systems.

The ideal candidate will have deep hands-on expertise in Node.js, TypeScript, Express.js, Microservices, Kafka, MongoDB, Redis, Cloud, Docker, and Kubernetes, with strong experience building and operating high-scale backend platforms in production environments.

The role also requires hands-on frontend development experience, particularly with ReactJS, with Angular experience being relevant for full-stack delivery. As a Technical Lead, you will provide technical direction to a cross-functional engineering team while remaining hands-on with architecture, development, code quality, performance, and delivery.

You will work closely with Product Owners, Architects, DevOps teams, and other engineering teams to deliver secure, scalable, reliable, and maintainable platforms supporting digital products and everyday banking capabilities.
