Bixal is seeking a Principal Full Stack Engineer to lead technical delivery on a federal platform that supports government wide regulatory planning and review. Federal agencies, oversight offices, and the public rely on these systems, which must stay available 24/7/365 while a modern replacement is built alongside them.

This role spans both sides of that work. You will keep the existing Java, Spring, and Oracle applications stable, performant, and secure, leading defect resolution and delivering approved enhancements. You will also design and build the replacement platform on cloud, container, and Dev Ops foundations, shaping its target architecture, its integrations with related federal systems, and the path for moving users and data off the legacy stack.

Priorities shift between the two, so we're looking for a hands‑on technical leader who is equally comfortable sustaining a production system and building a new one.

You will set technical direction, mentor engineers, and partner with our Project Manager, designers, and security lead. You will also work directly with the client's technical leads and product owner, translating complex trade‑offs into clear recommendations.

This role offers you a unique opportunity to make a meaningful impact on a project that aligns with Bixal’s mission of delivering innovative, human‑centered solutions. While the role has a fixed duration, we are committed to transparency and collaboration, keeping you informed about contract updates and new opportunities.
