Job description

Job Description

This position supports a U.S. federal government contract requiring U.S. citizenship and eligibility to obtain a Public Trust clearance.

ABOUT THE ROLE

iAdeptive Technologies is looking for a Lead Portal Engineer to own a user-facing portal end-to-end - the front-end architecture, the APIs and services behind it, and the human-centered design process that keeps it usable - on a modern, FedRAMP-authorized platform supporting a federal health agency. You are the technical owner of the portal: you architect it, build it, and ensure the people who use it can actually get their work done.

This is a lead role for an engineer who cares about the user, not a designer who also codes. You will own the full stack - React front end through APIs and services - and drive the HCD and UX process: framing user research, shaping design direction, and holding the bar on accessibility. A supporting design resource handles detailed design execution; you set the direction and own the outcome.

HOW WE WORK

Own the Portal End-to-End - You architect and build both the front end and the API layer, so the seams between design, front end, and services are decisions you made on purpose, not gaps nobody owns.

Engineer Who Drives Design - You lead the HCD process - user research, design direction, the design system - and partner with a supporting designer for execution. You treat usability as an engineering requirement, not a nice-to-have.

Built for Everyone - Accessibility is part of the definition of done. You build to Section 508 and WCAG from the start and treat a portal that excludes users as unfinished.

WHAT YOU WILL DO

• Own the portal end-to-end - architect and build the React front end and the APIs and services behind it
• Set technical direction and architecture for the portal and make the patterns the team builds against
• Design and build APIs (API-first), service integrations, and the front-end components that consume them
• Drive the human-centered design process - frame user research with agency staff, shape design direction, own the design system - partnering with a supporting designer for execution
• Own accessibility: build to Section 508 / WCAG and validate compliance as part of delivery
• Own quality across the portal stack - automated testing, CI/CD, and performance
• Use AI tooling to move faster while remaining accountable for every line that ships; keep deterministic logic in testable code
• Partner with security, data, and platform teams to ship into a FedRAMP-authorized environment, and mentor engineers

WHAT WE'RE LOOKING FOR

• 8+ years building production web applications, with recent hands-on full-stack delivery and API design
• Strong React and modern JavaScript/TypeScript, plus solid back-end experience building services and RESTful APIs
• Demonstrated ownership of a user-facing product end-to-end - front end, APIs, and the experience tying them together
• Real HCD/UX fluency: you have run or closely driven user research, design direction, and a design system, even if a designer handled execution
• Working knowledge of accessibility standards (Section 508 / WCAG) and a habit of building to them
• Demonstrated technical leadership while staying hands-on
• A habit of keeping deterministic logic in testable code and using AI tooling as an accelerator, you remain accountable for

BONUS POINTS

• FedRAMP / NIST 800-53 environments and agency security baselines
• Design tooling (Figma) and building or owning a design system
• Integrating with data platforms or BI/reporting layers (e.g., QuickSight or embedded analytics)
• AWS and secure cloud architecture; AI-assisted features (e.g., Amazon Bedrock)
• Building accessible, data-rich portals for large user bases

WHY iADEPTIVE

iAdeptive Technologies is an 8(a) small business building modern data, cloud, and AI systems for federal mission programs. We are engineers first. You will work alongside architects and engineers who write the code they design, ship into FedRAMP-authorized environments, and treat governance and security as part of the build rather than paperwork bolted on at the end.
