Infrastructure Engineer

About Fab2: The fab2 team designs all the hardware and software needed to manufacture chips and builds the fabs, tools, and components in-house. Founded by Sam Zeloof (known for making chips in his garage) and Jim Keller (a 40-year semiconductor industry leader), fab2 pushes the limits of what’s possible in semiconductor fabrication.

About The Team

The Infrastructure team is the backbone of fab2, building internal tools, databases, deployments, and networking infrastructure that empower software engineers. The team’s goal is complete command and control of everything in the fab, ensuring systems remain reliable, scalable, and secure as the company grows.

About The Role

As an Infrastructure & Site Reliability Engineer, you will design, build, deploy, and manage the on-prem backend infrastructure powering our semiconductor fab. This hands-on role involves owning all aspects of backend services from the ground up. Our infrastructure philosophy prioritizes minimalism, understandability, and proximity to hardware—expect to work primarily with bare-metal Linux, systemd, and single-file binaries in Rust, Go, and Python. We welcome exceptional early-career engineers to staff-level builders, valuing real-world experience, a love for low-level systems, and enthusiasm for performance engineering. Success means building a high-performance, rock-solid infrastructure that enables rapid, reliable fab operations without unnecessary abstraction. A portfolio or GitHub demonstrating your engineering excellence (e.g., backend services, homelab setups) is required to apply.

Responsibilities

• Design and implement lightweight, performant, and reliable software infrastructure for a semiconductor fab.
• Procure, deploy, and manage on-prem servers, virtual machines, and single-board computers running on semiconductor fabrication equipment.
• Deploy and manage backend services (e.g., Consul, Vault, Grafana, VictoriaMetrics, Alertmanager, Redpanda, Vector, Gitea, PostgreSQL).
• Design and set up low-level networking components (e.g., service discovery, DNS, reverse proxies, TLS, S3-compatible storage, VPNs).
• Scale the observability platform to ingest and display system metrics and high-frequency telemetry from fabrication equipment.
• Design and implement cross-site networking, replication, and backups.
• Automate OS image creation, deployment, and software build/deployment systems.
• Develop best practices and tools for security, authentication, authorization, and secrets management.
• Contribute to our in-house infrastructure-as-code tool.

Requirements

• BS in Computer Science, Computer Engineering, or equivalent demonstrated exceptional skill in software engineering.
• Hands-on experience in backend infrastructure or Site Reliability Engineering, successfully taking complex systems from concept to production.
• Deep proficiency in at least one statically-typed, compiled language, with strong systems fundamentals.

Nice-to-haves

• Hands-on programming experience in Rust or Go.
• Direct experience designing and managing on-premise, bare-metal infrastructure without heavy cloud abstractions.

Benefits

• Medical, Dental, and Vision insurance.
• Generous Paid Time Off (including holidays and sick time).
• Visa sponsorship.
• Life and Disability Insurance.
• Paid Parental Leave.
• 401(k) retirement plan.
• Weekly Learning & Development opportunities.
• Commuter benefits (parking, late-night Uber rides from the office).
• Daily lunches, dinners 3x per week, and a stocked office kitchen with snacks and beverages.

Pay

Annual salary range: $125,000 – $195,000, determined by qualifications and experience. Total compensation includes generous equity in fab2.
