Data Serv / xFact is seeking a Full Stack Developer to join our engineering team. In this role, you will design and deliver scalable, high-performance solutions across the full application stack - from API gateways and identity management - to relational and analytics databases - to modern frontend interfaces. You will contribute to both greenfield development and the continued evolution of existing systems within a Dev Sec Ops  environment.

The ideal candidate is a self-directed professional who thrives with autonomy - someone who can take ownership of a task and drive it to completion. Success in this role requires strong technical judgment, a commitment to quality, and the ability to collaborate effectively across teams. This is a hybrid role - qualified candidates must be available to spend a portion of their workweek in our North Andover office.
