USARemoteci/cdmonorepodeveloper tooling

Engineer focusing on developer experience, build systems, CI/CD, monorepo, and tooling for AI platform at Brainco.

Conditions

  • Competitive salary plus equity
  • Medical, Dental, and Vision coverage
  • 401(k)
  • Unlimited PTO
  • Daily lunches
  • Commuter benefits

Other

  • Brain Co. is an applied AI startup co-founded by Jared Kushner and Elad Gil, and backed by leading Silicon Valley builders including Patrick Collison and Andrej Karpathy.
  • We are building AI applications for the world's most important institutions, delivering impact on real-world problems across governments, healthcare systems, and critical industries.
  • Our progress so far:
  • Automated construction permitting for a sovereign government → 80% faster, unlocking $375M+ in value
  • Optimized supply chains for a leading global energy company → 30% lower cost, 99% reliability, preventing $100M+ in losses
  • Streamlined hospital patient care across national health systems → 40% better outcomes, 80% less admin work
  • Company momentum:
  • Raised a $55M Series A from leading investors
  • Built a team of 70+ AI experts from Tesla, Google DeepMind, NVIDIA, and Databricks
  • At Brain Co., we focus on applying frontier AI to real institutional challenges, working alongside governments, healthcare systems, and critical industries to modernize how essential services operate.
  • We are looking for leaders who want to help bring new technology into institutions that impact millions of people.
  • You'll join the DevX pod — the team that owns the build system, CI/CD, monorepo, and developer tooling that set the ceiling on how fast every other engineer at BrainCo can ship.
  • This is a force-multiplier role : your work compounds as we add teams, services, and customers. BrainCo's monorepo spans Python, TypeScript, and Go, runs on Nx, and ships to production environments that include regulated and air-gapped customer deployments. As we grow from a handful of teams to dozens, the leverage of this role compounds.
  • Your job is to discover, measure, and remove developer friction. You should be comfortable going from "this workflow is slow or confusing" to instrumented evidence, a shipped improvement, and clear before / after impact.
  • Own the architecture and ongoing health of our Nx-based monorepo: project graph, dependency boundaries, language toolchains (pnpm, uv, Go), and code generation patterns.
  • Make builds and tests fast, reliable, and incremental at scale.
  • Build CI/CD systems with strong guarantees around correctness, reproducibility, and speed.
  • Own pipeline architecture, caching, parallelism, secret flow, and release engineering for environments that include regulated and air-gapped customer deployments.
  • Design internal CLIs, scaffolding, local dev stacks (Tilt, Docker, Kubernetes), and code-quality infrastructure (lint, typecheck, format, pre-commit).
  • Own the developer-facing experience for deployment and environment workflows, while partnering with Infrastructure on the underlying cloud, Kubernetes, networking, and runtime substrate.
  • Create paved paths the team actually wants to use — not guardrails that get bypassed.
  • Run the build, CI, and dev infra with real SLOs, observability, and on-call rigor. Internal downtime is downtime.
  • Identify what's slowing engineers down, instrument it, and fix it from first principles.
  • Move from "X is slow" to a measured, deployed improvement with clear before/after numbers.
  • End-to-end ownership: architecture, implementation, rollout, observability, on-call, and iteration based on internal user feedback.
  • Partner closely with every engineering team. Drive adoption through quality, not mandates.
  • We're looking for engineers who treat developer experience as a product — engineers who reach for users, not just specs.
  • Have 5+ years building developer-facing infrastructure: monorepo platforms, build systems, CI/CD, or internal tooling.
  • Have hands-on depth with at least one modern monorepo tool (Nx, Bazel, Pants, Buck, Turborepo) and the willingness to go deeper.
  • Have strong fluency with CI/CD systems at scale (GitHub Actions, Buildkite, CircleCI, or similar): matrix design, caching strategies, secret flow, parallelism.
  • Are fluent in at least two of: Go, Python, TypeScript, Rust, Bash.
  • Have shipped developer platforms that real engineers adopted.
  • Have measured developer friction and shown clear before / after impact from tooling, CI, build, release, or workflow improvements.
  • Have strong intuition for developer experience, paved paths, and long-term maintainability.
  • Are comfortable owning the full lifecycle: design doc, MVP, hardening, adoption.
  • Have owned developer-facing systems with real uptime and operational responsibility.
  • Are familiar with observability tooling and incident response.
  • Built or significantly contributed to a remote build cache, custom build system, or hermetic build pipeline (Bazel, Nix, etc.).
  • Led a polyrepo → monorepo (or reverse) migration at scale.
  • Experience applying DORA / SPACE or other DX metrics in practice.
  • Background in release engineering, supply-chain security (SLSA, Sigstore), or artifact management.
  • Built internal PaaS, dev environments, or scaffolding generators.
  • Experience building or maintaining a frontend platform or design system — shared component library, design tokens, Storybook / visual-regression infra, a11y or perf budgets across apps.
  • Open-source contributions to Nx plugins, GitHub Actions, or related developer tooling.
  • Exposure to multi-tenant, regulated, or air-gapped deployment environments.
  • You'll set the ceiling on how fast every other engineer at BrainCo can ship. As we grow from a handful of teams to dozens — building AI systems for governments and regulated industries — the platform that lets us move quickly without breaking what matters becomes one of the highest-leverage systems in the company.
