Role Summary:
The Senior Full Stack Engineer will be a core contributor to the software development lifecycle, responsible for coding, unit testing, and implementing complex software designs for the IRS IRPPS modernization effort. This engineer must be adept at building ultra-high-throughput systems capable of handling massive spikes in data during the peak tax filing season.
Key Responsibilities:
- Develop, unit test, and implement full-stack application designs under the direction of the Architect/Technical Lead.
- Build and optimize highly scalable, transactional services capable of meeting strict SLAs, specifically processing at least 8,800 records per second.
- Develop microservices and APIs using Java 17/21, Spring Boot, and Informatica for data routing, validation, and posting.
- Support 24x7 Operations and Maintenance (O&M) during peak filing seasons, providing incident response, defect remediation, and root-cause analysis.
- Develop automated testing assets and ensure code complies with IRS security, engineering, and architecture standards.
Size, Scope, and Complexity Expectations:
- Size/Complexity: The most critical expectation is documented, verifiable experience implementing high-throughput, transactional systems capable of processing at least 8,800 records per second. Resumes must explicitly demonstrate the candidate's ability to engineer code that sustains this specific velocity under SLA constraints.
- Scope: Must demonstrate recent (within 5 years) experience developing within complex modernization ecosystems, specifically utilizing Java and Informatica to migrate data processing from legacy formats to modern event-driven architectures. The candidate must have experience managing severe volume spikes, similar to the IRS requirement where 80% of an annual 9.2 billion record volume occurs during a concentrated peak season.
Required Education & Experience:
- Education: Bachelor’s degree in Computer Science (or equivalent).
