UX Developer (W2 Only - Onsite)

TEKsystems•Charlotte, NC

3d•$75 - $95•Onsite

About The Position

You will build the primary user interface for a SaaS security platform—the layer that application teams, security architects, and business stakeholders interact with daily. This is not a pure UX design role or a generic frontend position. You are a hands-on engineer who can move quickly, integrate directly with FastAPI services, and apply practical UX thinking (≈25%) to make complex security data intuitive and actionable. If users don’t trust or actively use the UI, the platform cannot scale—your work is critical to adoption.

Requirements

7+ years of experience with React and TypeScript
Data visualization experience (tool flexible; preference to avoid Power BI)
Experience with GraphQL
Experience building analytical drill-down dashboards or large-scale tools
Strong experience developing high-performance web applications handling large datasets
6+ years building production web applications
Strong expertise in React (or similar frameworks), TypeScript / JavaScript, and State management for data-intensive applications
Comfortable working in fast-paced environments with iterative development
Hands-on experience with FastAPI
Experience working with Async APIs and JSON schema-based services
Ability to independently troubleshoot frontend-backend integration issues
Proven ability to simplify complex technical data
Experience building internal platforms or enterprise tools
Strong collaboration with engineers, security teams, and stakeholders

Responsibilities

Design and build the core application UI used by SaaS application owners, Security architects, and Risk and oversight teams.
Develop features such as SaaS application inventory views, Control adherence status (PASS / FAIL / INSUFFICIENT EVIDENCE), Drill-down flows from findings to supporting evidence, and Change or drift tracking ("what changed since last run").
Build clean, scalable, and maintainable UI components that can evolve into a full product experience.
Work closely with FastAPI-based backend services.
Define and consume REST and async APIs, and Graph-based or aggregated endpoints.
Partner with integration engineers to shape UI-friendly data contracts.
Occasionally build lightweight FastAPI endpoints to support UI functionality.
Apply practical UX principles to reduce cognitive load for complex, security-heavy data and make control failures understandable without deep security expertise.
Collaborate with security and engineering teams to clearly communicate findings, avoid ambiguous or overly alarmist messaging, and design simple, effective workflows that answer: What failed? Why did it fail? What happens next?
