Frontend Engineer

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 600+ fast-growing startups like Ashby, Slope, AtoB, Pylon, Superblocks, 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 our seed round from a Tier 1 VC firm.

• We're growing extremely fast and have more than 6x'ed our revenue in the last 4 months with a team of just 4.
