About the Job:

As a Software Engineer focussed on internal developer enablement, you will optimize and expand our internal shared development and deployment tooling so our nearly one hundred developers can achieve peak productivity. Your responsibilities would include helping manage and improve our continuous integration and deployment infrastructure, extending our tooling to eliminate toilsome developer tasks, and maintaining and improving code libraries shared by our software team. We're looking for someone who cares deeply about streamlining the developer experience. We believe in the power of Feature Management, so you can also plan on helping to develop best practices for use of our own Feature Flag system, as well as any future products.

Our platform serves over twenty trillion feature flags daily. The core technologies we use include Golang, NodeJS, CircleCI, Okteto, Spinnaker, Rust, AWS, Terraform, MongoDB, ElasticSearch, Redis, CockroachDB, and NATS. As part of our you-build-it-you-run-it culture, all developers may be responsible for supporting applications in production, including on-call. Off-hours on-call is optional and compensated in addition.

What You'll Get to Do

  • Improve engineering standards, tooling, and processes.

  • Maintain and improve shared libraries across our codebase.

  • Monitor and improve our DORA metrics, notably lead time and deployment frequency, for multiple services.

  • Build and maintain infrastructure hosted in the cloud.

  • Actively participate in code reviews.

  • Write and review technical proposals.

  • Ensure newly hired engineers ramp up quickly.

  • Collaborate daily with developers from across the engineering organization.

  • Participate in engineering-wide tech-debt focus weeks and hack-a-thons.

On day one, you should have:

  • Experience with server-side web development (e.g. in Java / Scala, Ruby, Python, Golang, Node.js).

  • A commitment to working in a communicative and collaborative environment.

  • An unshakeable need to eliminate toil.

  • Empathy for the customers of the tooling you will build and maintain.

Bonus Points

  • You’ve written your own open-source developer tools.

  • React tooling’s your thing.
