• Lead technical discussions, contribute to design documentation, and provide guidance on modern software architectures.
• Drive the adoption of modern engineering practices, including Agile, DevOps, and CI/CD, fostering a culture of continuous delivery and improvement.
• Implement trunk-based development, feature flags, and progressive delivery strategies to enable continuous integration and rapid, reliable releases.
• Apply a test-automation-first mindset, utilizing Test-Driven Development (TDD) and Behavior-Driven Development (BDD) to ensure high unit test coverage and code quality.
• Collaborate closely with DevOps teams to optimize deployments, enhance observability, and ensure production resilience through continuous monitoring.
• Implement and enforce secure coding practices, conduct vulnerability assessments, and ensure compliance with security standards.
• Mentor junior engineers and foster a culture of engineering excellence and continuous learning within the team.

• Proven experience with event-driven and messaging systems, such as Kafka, Solace, Tibco, or MQ.
• Proficiency with Spring Boot for application development and OpenShift or Kubernetes for container orchestration.
• Strong experience with relational databases (e.g., Oracle) and SQL.
• Demonstrated experience with trunk-based development, feature flags, and progressive delivery strategies.
• Proficiency in applying Test-Driven Development (TDD), Behavior-Driven Development (BDD), and maintaining high test coverage.
• Strong understanding of CI/CD pipelines, DevOps principles, and infrastructure as code.
• Experience conducting thorough code reviews, performing vulnerability assessments, and applying secure coding practices.
• Knowledge of performance tuning, observability (logging and monitoring), and ensuring production stability.
• Familiarity with Agile frameworks and experience working in a fast-paced, collaborative product development environment.
