Why the company?

the company is a consulting company headquartered in Fairfax, VA, working alongside governments and organizations to help them deliver better services and experiences to the communities they serve. Using evidence-based knowledge and technology, the company empowers clients to deliver on their missions more effectively by fostering a culture of learning and continuous improvement.

About the role:

the company is seeking a Principal Full Stack Engineer to lead technical delivery on a federal platform that supports governmentwide 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 DevOps 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.

Responsibilities:

• Serve as technical lead for the program, setting engineering standards, reviewing code and architecture, and guiding technical decisions across existing and new systems.
