Role Description

As a Software Development Engineer Senior, you will contribute to the design, development, and evolution of microservices and web applications deployed in AWS, working closely with product owners, test engineers, and DevOps teams. You will apply strong computer science fundamentals, cloud‑native patterns, and modern development practices to solve complex problems at scale.

This role requires proven, hands‑on experience with Test‑Driven Development (TDD) and Spec‑Driven Development (SDD), using clear specifications, acceptance criteria, and executable tests to drive design, implementation, and validation.

You will operate within a modern SDLC that incorporates AI‑assisted and agentic development approaches to improve delivery efficiency and quality, while maintaining strong ownership of code quality, correctness, and long‑term maintainability in an Agile Development Process Environment.

We are looking for a Software Development Engineer Senior who will:

  • Build, enhance, and maintain microservices and web applications with a strong focus on reliability, scalability, performance, and maintainability.
  • Design and implement cloud‑native services and architectures in AWS, aligned with DevOps and CI/CD best practices.
  • Apply Test‑Driven Development (TDD) as a core engineering practice, ensuring strong unit and integration test coverage.
  • Practice Spec‑Driven Development (SDD) by collaborating with product and QA on well‑defined specifications, acceptance criteria, and testable requirements.
  • Leverage AI‑assisted and agentic development tools for implementation, refactoring, and analysis, while retaining full accountability for design decisions and outcomes.
  • Write clean, readable, and maintainable code; actively participate in code reviews and contribute to shared engineering standards.
  • Collaborate across product, QA, and DevOps teams to deliver customer‑focused solutions and continuously improve delivery efficiency.

Qualifications

  • Bachelor’s degree in computer science or a related field, or equivalent practical experience.
  • Intermediate to fluent English proficiency in a professional business environment.
  • 7+ years of software development experience, including 2+ years building and deploying applications in AWS.
  • Experience guiding and coaching other junior developers.
  • Experience with Cloud Native architecture (Microservices, DevOps, CI/CD, Kubernetes).
  • Strong experience with JavaScript/TypeScript, Angular, and/or Python.
  • Solid understanding of service‑based architectures, RESTful APIs, and scalable microservices.
  • Experience with SQL and relational databases (Oracle, PostgreSQL).
  • Proven, hands‑on experience with Test‑Driven Development (TDD).
  • Experience working with specifications, acceptance criteria, or behavior‑driven approaches as part of Spec‑Driven Development (SDD).
  • Experience working in a modern SDLC that incorporates AI‑assisted software delivery, with clear ownership of validation and outcomes.
  • Experience working in Agile teams and collaborating across engineering, product, and QA.

Requirements

  • Experience with scripting languages such as Shell Script, Bash, or Perl.
  • Experience contributing to shared architectural, testing, or coding standards within a development team.
