- Contribute to software architecture decisions and technical design discussions.
- Build modular, extensible, maintainable, and performant applications.
- Design, execute, and maintain unit, functional, and integration tests.
- Apply secure coding practices throughout the software development lifecycle.
- Participate in code reviews and contribute to engineering quality standards.
- Support system performance optimization, scalability improvements, and reliability initiatives.
- Design applications with observability, operational readiness, and supportability in mind.
- Research new technologies, frameworks, and engineering practices.
- Participate in proof-of-concepts and technical experimentation.
- Troubleshoot application and production issues using structured root cause analysis.
- Support applications throughout their lifecycle, including production support.
- Collaborate with cross-functional stakeholders to deliver business solutions.
About You
- Has ability to write secure code in Java and familiar with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management
- Efficient in Java, Spring, SpringBoot, JPA, Angular, SQL
- Understands the basic engineering principles used in building and running mission critical software capabilities (security, customer experience, testing, operability, simplification, service-oriented architecture)
- Able to perform debugging and troubleshooting to analyze core, heap, thread dumps and remove coding errors
- Understands and implements standard branching (e.g., Gitflow) and peer review practices
- Experience in leveraging AI tooling for improved efficiency and quality of the software
- Has skills in test driven and behavior driven development (TDD and BDD) to build just enough code and collaborate on the desired functionality
- Understands use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from the gang of four) to implement efficient code
- Understands and implements Application Programming Interface (API) standards and cataloging to drive API/service adoption and commercialization
- Has skills to author test code with lots of smaller tests followed by few contract tests at service level and fewer journey tests at the integration level (Test Pyramid concept)
- Apply tools (e.g., Sonar, Zally, Checkmarx ) and techniques to scan and measure code quality and anti-patterns as part of development activity
- Has skills to collaborate with team and business stakeholders to estimate requirements (e.g., story pointing) and prioritize based on business value
- Has skills to elaborate and estimate non-functional requirements, including security (e.g., data protection, authentication, authorization), regulatory, and performance (SLAs, throughput, transactions per second)
- Has skills to orchestrate release workflows and pipelines, and apply standardized pipelines via APIs to achieve CI and CD using industry standard tools (e.g., Jenkins, XL Release, others).
- Has skills to understand, report, and optimize delivery metrics to continuously improve upon them (e.g., velocity, throughput, lead time, defect leakage, burndown)
- Has skills to document and drive definition-of-done for requirements to meet both business and operational needs
- Understands how to build robust tests to minimize defect leakage by performing regression, performance, deployment verification, and release testing
- Has skills to conduct product demos and co-ordinate with product owners to drive product acceptance signoffs
- Strong problem-solving and communication skills, fluent English is a must.
