Systems 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 hit $1M ARR with less than 9 months in the market, and have continued our rapid growth from there.

You are a good fit if you

• Have developed and scaled distributed systems and enjoy digging into performance and reliability issues across the filesystem, network, and storage stack.

• Are comfortable writing and debugging in C, C++, Go, Rust, or Zig, and care deeply about efficiency, correctness, and safety at the systems level.

• Are excited by the idea of self-hosting and managing infrastructure with build automation and configuration management tools (e.g., Ansible, Puppet, Chef).

• Have familiarity with distributed storage systems like Ceph or MinIO, or are eager to get hands-on with them.

• Have 2+ years of software development experience, ideally in performance-critical or distributed environments.

• Enjoy working in person 5 days a week in NYC with a small, tight-knit team.

• Thrive in the ambiguity of an early-stage startup and are energized by building from first principles.
