Senior Software Developer, Platform Engineering

Rocket Mortgage•Seattle, WA

About The Position

As a Senior Software Engineer for a team in the Platform Engineering organization, you'll shape how Redfin's frontend engineers build, test, and ship software. This specific team owns the frontend platform infrastructure that powers ~30 React applications — the build tooling, testing frameworks, CI/CD pipelines, and developer experience integrations that let teams focus on delivering customer value instead of fighting their tools. You won't just be writing code; you'll be multiplying the productivity of the entire frontend engineering organization. This role leads the integration of generative AI into our platform tooling, creating intelligent systems to eliminate toil and automate repetitive tasks. Join us if you're energized by high-leverage problems that directly improve the daily experience and confidence of hundreds of engineers.

Requirements

5+ years of experience in frontend or full-stack development, specializing in developer tooling, platform engineering, or infrastructure, with deep expertise in JavaScript/TypeScript and React.
Familiarity with leveraging and optimizing testing frameworks including: Jest, Vitest, Playwright, visual regression testing.
Familiarity with building/maintaining scalable CI/CD pipelines using GitHub Actions or similar.
Experience integrating Rust-based tools into existing JS frameworks.
Implemented team-wide AI tools to speed up development, debug processes, and improve scalability for front end development.
Familiarity with containerized workflows (Docker), observability/monitoring tools (Datadog or similar), and AI code generation tools (e.g., Claude Code).
Proven ability to navigate ambiguity, communicate clearly with diverse stakeholders, drive technical consensus across teams, and manage priorities within large, complex codebases.

Responsibilities

Drive significant improvements to and ensure the reliability of core frontend infrastructure: build tooling, testing, and CI/CD pipelines.
Design and build generative AI tooling to accelerate frontend code creation, testing, and deployment.
Support engineering productivity by reducing toil, eliminating friction, and establishing scalable best practices across multiple frontend teams.
Research and champion forward-thinking solutions for frontend developer experience, leveraging or introducing new technologies as needed.
Support the implementation roadmap for core platform infrastructure, working with stakeholders to resolve technical debt and propose scalable solutions.
