  • Review and provide detailed feedback on code submissions from other contributors to ensure technical accuracy and maintain high-quality standards.
  • Collaborate with cross-functional teams to enhance data creation infrastructure and improve overall engineering processes.
  • Document and communicate reasoning, design decisions, and system-level trade-offs clearly and effectively.


Qualifications:

  • 6+ years of professional software engineering experience with Java in production codebases.
  • Strong programming fundamentals and proficiency in Java, Spring, and Spring Boot.
  • In-depth understanding of backend systems, including APIs, databases, and microservices architecture.
  • Experience in working with complex or large-scale applications involving multiple components and dependencies.
  • Proficiency in writing unit and integration tests, ensuring code reliability and maintainability.
  • Excellent problem-solving and debugging skills with a focus on performance optimisation.
  • Ability to work independently and deliver high-quality output in a fast-paced environment.
  • Strong written and verbal communication skills with attention to clarity and technical details.
