As a Frontend Engineer, you will focus on building high-performance UIs using React, work closely with design, and improve browser performance.
The summary above was generated by AI

Overview
At Blacksmith, we provide cloud infra to help companies run their CI (GitHub Actions) substantially faster and cheaper. Our mission is to build a CI cloud. Our bet is that CI, as a class of workloads, is ready to be unbundled from the hyperscaler clouds (AWS/GCP/Azure). This is a bold statement, and we have an ambitious roadmap ahead.


Some things we're proud of

  • We orchestrate millions of VMs for CI jobs each month over our own fleet of bare metal hardware.

  • We power CI for 900+ fast-growing startups like Supabase, UserTesting, Ashby, Slope, AtoB, Pylon, and Finch.

  • Founders: Aditya Maru and Aayush Shah were early systems engineers at Cockroach Labs. Aditya (JP) Jayaprakash worked on search infra and was later a founding member of the ads team at Faire.

  • We went through Y Combinator's W24 batch and raised $13.5M Series A from Google Ventures

You are a good fit if you

  • Have strong CS fundamentals and a deep understanding of React and modern frontend development.

  • Can work closely with design to build polished, high-performance UIs — and aren’t afraid to go deep on browser performance, rendering bottlenecks, or complex component architecture.

  • Have 3+ years of software development experience.

  • Enjoy working in person 5 days a week in NYC or SF.

  • Enjoy working at a very early-stage startup and are comfortable with ambiguity.

Bonus

  • You’ve dabbled in your own side hustles or start-up projects.

  • You’re comfortable creating new processes and iterating on them quickly.

Compensation and benefits

  • Compensation: We want to attract the best people to come work with us and offer competitive compensation packages

  • Benefits: We offer premium health, dental, and vision coverage and 16 weeks paid parental leave for new parents.

  • Time off: We offer unlimited PTO and encourage folks to take their birthday off!

  • Foodie Benefits: You and a +1 get a Michelin star dinner on us for your birthday

  • 401(k): Helps you save for retirement
