This role is with one of Dex's trusted partner companies.

The role

This company is building the future of data orchestration and observability.

They\'re bringing CI/CD-style rigor to data teams with an AI-native, declarative framework that lets engineers explicitly define pipeline behavior.

Backed by leading investors, they\'ve grown ARR 4x in the last year and are on track to do it again.

This is a senior frontend seat on a small engineering team of four.

You\'ll own the entire user-facing surface: how data engineers author pipelines, watch them run, and debug when things break.

This isn\'t just building screens; it\'s end-to-end system design, setting the technical bar, and driving the full development lifecycle.

You\'ll deploy to production multiple times a day, with real scope to influence product direction and contribute to new AI initiatives.

  • The work
  • Own the entire frontend surface, designing and implementing features that let data engineers declaratively define, run, and debug complex pipelines.
  • Drive end-to-end system design, from component architecture and state management to performance at scale, for a product that deploys multiple times daily.
  • Set the technical bar for frontend development, influencing best practices and code quality across a small, high-agency engineering team.
  • Contribute across the stack, including serverless Python/Express services, and explore new AI-native features as the product evolves.

What You Bring

  • 5+ years shipping production frontend products, with deep expertise in React and Type Script.
  • A concrete grasp of frontend system design: you can reason about state, component architecture, and performance at scale.
  • Experience owning systems end-to-end in a cloud environment, comfortable driving projects from design to deployment.
  • You\'re opinionated, resourceful, and want a hand in product direction, not just execution.
