The Role and Team

You will be a senior technical leader within the team responsible for developing, scaling, and maintaining the DXA (Digital Experience Analytics) reporting tool. A primary focus of this role will be driving the strategic migration of the DXA portal from our legacy Backbone framework to our modern, Alchemy‑based React framework.

Additionally, you will help architect and manage the Node.js‑based microservices that power the DXA portal. As our team actively works toward achieving FedRAMP compliance for our reporting platform, you will play a critical role in aligning our frontend architecture, data handling, and security practices with federal compliance standards. As a senior member of the team, you will not only write high‑quality code but also establish best practices, mentor other developers, and collaborate closely with product and design teams to shape our technical roadmap.

Responsibilities

• Architect & Scale: Design and implement robust, reusable web architectures, state management systems, and client‑side algorithms for the DXA portal.
• Drive Migration: Take a leading role in successfully transitioning legacy Backbone codebases into a modern, performance‑optimized React/Alchemy architecture.
• Security & Compliance: Collaborate with security and engineering teams to ensure frontend interfaces, data storage, network calls, and authentication flows meet FedRAMP compliance requirements and federal security standards.
• Technical Leadership & Mentorship: Guide, mentor, and perform constructive code reviews for junior and mid‑level engineers to elevate the team’s technical capabilities.
• End‑to‑End Ownership: Partner with product managers and designers to translate complex requirements into scalable technical designs, owning projects from concept through to deployment.
• Quality & Best Practices: Champion code quality, performance optimization, accessibility (a11y), security hardening, and comprehensive testing strategies (unit, integration, and end‑to‑end).

Candidates based in the Tysons vicinity will be prioritized as this role is Hybrid, 3 days per week onsite.
