Senior Go Engineer, Full Stack

This is a role for a generalist who enjoys the variety of switching between building sleek interfaces and robust server-side logic. You’ll thrive here if you can:

• Own the Full Lifecycle: Build, scale, and maintain modern web applications where the logic is split evenly between TypeScript frontend and our Go (Golang) backend.

• Bridge the Gap: Design and implement clean APIs in Go while ensuring they are seamlessly integrated into a performant, accessible React frontend.

• Architect for Scale: Maintain high standards for code quality and performance across the entire stack, from frontend component libraries to backend microservices.

• Collaborate Broadly: Work closely with Product and Design to turn ambiguous requirements into polished features.

• Master the Ecosystem: Help evolve our infrastructure and lean into AI tools, understanding their strengths and limitations to accelerate our workflow.

• Experience: at least 6+ years of professional software engineering experience in a production environment.

• The Backend: Proven experience architecting and maintaining high-scale web APIs. Golang is our primary language. You don't need to be a Go veteran on day one—as long as you have rock-solid backend fundamentals and are willing to master Golang.

• The Frontend: Fluency in React and TypeScript. You move comfortably through modern tooling (e.g., Redux Toolkit, Styled Components, Storybook) and you care deeply about quality, ensuring your features are backed by solid testing frameworks (Jest, Cypress, or Playwright).

• System Ownership: A "DevOps" mindset, comfortable with CI/CD, automated testing, and version control.

• Communication: Fluent English and the ability to explain complex technical trade-offs to non-technical stakeholders.
