Backend Full Stack Engineer Jobs in Coppell, TX (NOW HIRING)

Title: Senior Full Stack Engineer

Location: Dallas, TX

About the Role

Senior engineer owning the customer-facing experience of a metrics and reporting platform — a React application, module-federated into a wider micro-frontend shell, served by a FastAPI backend over a curated analytics data layer. Dashboards, tables, filters, charts, and saved views are yours: the layer where correct metrics become answers a customer can act on.

This is a full-stack position with a frontend centre of gravity. You will spend the majority of your time in TypeScript and React, and you are expected to be productive in the Python and FastAPI codebase as well — extending an endpoint, writing a migration, and reviewing backend pull requests.

This cross-capability is a requirement of the role, not a preference. The team is deliberately structured so that no layer has a single owner, with every engineer able to take a feature through end-to-end development and support it in production. If you would prefer to stay within a single layer, this is not the right role.

Key Responsibilities

• Own the customer-facing application — dashboards, data tables, filtering, charts, and saved views, built in React and TypeScript
• Integrate with the platform shell — ship the application as a module-federated remote that behaves as a first-class part of the host application
• Own server state — TanStack Query cache keys, invalidation, pagination, and optimistic updates against the metrics API
• Build data-dense interfaces — TanStack Table with sorting, filtering, and virtualization that stays responsive at scale
• Design the visualization layer — Recharts implementations chosen for the question the user is actually asking, not for decoration
• Enforce the API contract on the client — Zod schemas validating at the boundary, with inferred types flowing through the application
• Make state addressable — typed routing with TanStack Router, filters and saved views represented in the URL so any view can be shared
• Uphold the design system — Tailwind CSS with shadcn/ui, composing and extending components rather than forking them
• Build and review backend work — extend FastAPI endpoints, write database migrations, review backend pull requests, and take end-to-end ownership of a slice when the work calls for it
• Own quality and performance — Vitest coverage, render performance, bundle size, and accessibility as delivery standards rather than afterthoughts
• Support the application in production — triage and resolve customer-raised issues across the stack, from rendering defects through to the queries behind them

Qualifications

• 6+ years building production web applications; 4+ years with React at scale
• Working proficiency in Python (required) — able to extend a FastAPI endpoint, write a migration, and review backend code to the team standard.
• Strong TypeScript — generics, discriminated unions, and disciplined use of the type system rather than escape hatches
• Modern React: hooks, composition patterns, and hands-on render performance optimization
• Next.js and Vite build tooling
• TanStack Query in production — caching, invalidation, and pagination strategy
• TanStack Table for large, interactive datasets, including virtualization
• TanStack Router or comparable typed routing, with search-parameter state management
• Zustand or equivalent for genuine client state, and a clear sense of what does not belong there
• Zod for runtime schema validation at the API boundary
• Data visualization experience with Recharts, D3, or similar, and sound judgement about chart selection
• Tailwind CSS and component libraries such as shadcn/ui or Radix
• Vitest and React Testing Library
• Comfort with SQL: reading and writing queries against a relational database
• Micro-frontend or module federation experience is a strong plus
• Experience with analytics, reporting, or dashboard products is a strong plus
• Accessibility (WCAG) and design-system contribution experience is a plus
• Strong written communication and the ability to work within defined overlap hours across time zones
