Senior Platform / Build Engineer, NIX

About the role

This position is based in either Marina Del Rey (LA) or San Francisco onsite. We are open to connecting with local candidates and those open to relocation.

Responsibilities

• Design, build, and maintain Nix-Native CI and deployment pipelines that take code from commit to production with zero-downtime deploys
• Maintain and improve our internal package set in order to enable software distribution across the company and to our customers and drive adoption of NixOS across our infrastructure
• Own and optimize our CI compute pool — improve pipeline throughput, identify and resolve bottlenecks, and manage resource allocation across a growing, compute-intensive test and verification workload
• Partner with engineering leadership on hardware capacity planning and infrastructure procurement as compute needs scale
• Improve developer ergonomics around Nix — tooling, documentation, standards, and workflows that keep engineers productive
• Define and evolve our deployment strategy, including how software is delivered to customers across multiple regions/markets
• Operate and support high-consequence, customer-facing production systems with rigor and care
• Mentor and provide Nix expertise to the broader engineering org as the platform team grows

Requirements

• 5+ years building internal developer platforms, build systems, or CI/CD infrastructure
• Hands-on experience with a Nix-based build system or comparable for a real product with real customers
• Proven experience delivering software reliably for a live system with a large user base, including zero-downtime deployment practices
• Experience managing high-consequence systems where reliability and correctness directly impact customers
• Experience owning and optimizing a large CI system and compute pool — resource management, pipeline performance, and bottleneck analysis
• Deep understanding of how build systems and packaging ecosystems work (Nix, Nixpkgs, NixOS, or comparable systems such as Bazel)
• Experience with infrastructure-as-code and configuration management tooling (e.g., Terraform, Ansible, Chef, Salt)
• Experience managing and owning cloud infrastructure (AWS, Google Cloud, or Microsoft Azure) or on-premise hardware systems
• Experience with globally distributed deployment and the operational challenges that come with it
• Experience scaling platform infrastructure at a fast-growing startup
• Experience with FedRAMP, ITAR, SOX, or other relevant security/compliance frameworks
• Knowledge of the Nix packaging ecosystem and/or the NixOS module system
• Familiarity with the build tooling behind one of Revel's core language stacks — e.g., CMake/pkg-config (C++), Cargo/Rustc (Rust), Go, Vite (TypeScript), or setuptools/uv/hatchling (Python)
• Linux fundamentals: kernel and kernel modules, Kconfig, systemd, Secure Boot, and system hardening
• Experience with Linux on embedded targets

Qualifications

Must Have:

• Experience with NixOS in production (not just Nix for builds/packaging)
• Experience with Bazel or other large-scale build systems
• Experience with globally distributed deployment and the operational challenges that come with it
• Experience with hardware/compute procurement and capacity planning
• Experience scaling platform infrastructure at a fast-growing startup
• Experience with FedRAMP, ITAR, SOX, or other relevant security/compliance frameworks
• Knowledge of the Nix packaging ecosystem and/or the NixOS module system
• Familiarity with the build tooling behind one of Revel's core language stacks — e.g., CMake/pkg-config (C++), Cargo/Rustc (Rust), Go, Vite (TypeScript), or setuptools/uv/hatchling (Python)
• Linux fundamentals: kernel and kernel modules, Kconfig, systemd, Secure Boot, and system hardening
