• Work with Quality Assurance (QA) engineers to ensure automated test coverage and proactively fix bugs and defects.
• Partner with DevOps teams to automate build, deployment, and monitoring pipelines.
• Develop and maintain scalable, high-performance APIs and backend services in a cloud-native environment.
• Implement modern software development practices, including TDD, pair programming, and CI/CD.
• Conduct code reviews, enforce security best practices, and ensure software craftsmanship standards.
• Design and document system architecture, ensuring compliance with government security and regulatory standards.
• Excellent written and verbal communication skills to pitch ideas and influence stakeholders.
• End to end experience working with product team to build products.
• Ability to work effectively and independently under pressure and prioritize effectively to meet tight deadlines.
