Job Description & How to Apply Below

We are looking for a senior engineer who can take end-to-end ownership of complex, distributed systems - from a clean, accessible UI all the way down to the database and the pipelines that ship it. You will design, build, and operate cloud-native microservices in Java 17/21 with Spring Boot expose well-versioned APIs consumed by modern Typescript front ends, and drive engineering practices such as TDD/BDD, API-driven development across the team.

This role is hands-on. You will write production code daily, review pull requests, mentor mid-level engineers, and influence architectural decisions that affect multiple squads. We expect you to care equally about correctness, performance, developer experience, and the people on your team.

What You will Do -
  • Design and build microservices in Java 17/21 with Spring Boot 3.x.
  • Practice API-first development with OpenAPI; deliver well-versioned, well-tested REST APIs.
  • Build responsive front-ends in Angular/React with Type Script.
  • Model and tune data in SQL and No

    SQL databases.
  • Own CI/CD pipelines in Git Hub Actions, including build, test, scan, and deploy stages.
  • Containerized with Docker and run on Kubernetes in AWS / Azure / GCP cloud.
  • Drive TDD/BDD with JUnit, Mockito, Test containers, Cucumber, and front-end testing tools.
  • Conduct Git Hub code reviews, manage branching strategy, and mentor engineers.
You Should Have -
  • 7+ years of software engineering experience, with strong Java + Spring Boot depth with Python, Perl.
  • Production experience with microservices, Kubernetes, and at least one major cloud provider.
  • Hands-on Angular/React or similar UI frameworks with solid Type Script.
  • A real TDD/BDD habit — tests before, or alongside, the code.
  • Comfort with Git Hub Actions (or similar) and Infrastructure-as-Code (Terraform preferred).
  • Clear writing, ownership mindset, and a track record of mentoring
