Job description

Beam is an ultrafast AI inference platform. We built a serverless runtime that launches GPU‑backed containers in less than 1 second and quickly scales out to thousands of GPUs. Developers use our platform to serve apps to millions of users around the globe. We're backed by Y Combinator, Tiger Global, and prominent developer‑tool founders, including the founder of Snyk and former CTO of GitHub.

About The Role

We're building out our own GPU capacity across new data center sites, and we need someone to stand up that infrastructure and drive deployments to completion.

• Deploy and validate data center network infrastructure (front‑end, back‑end, BMS, management): configure switches, install and validate optics, coordinate cabling, and drive deployments to completion.
• Ensure physical connectivity meets production standards: coordinate fiber remediation, validate insertion loss and OTDR traces, troubleshoot optical‑layer issues, and document as‑builts.
• Manage hardware logistics: device staging, rack/stack coordination, RMA, DCIM updates, inventory, and vendor shipments so devices are ready when deployments need them.
• Partner with DC Operations, ICT, Hardware, and Network Engineering to identify blockers early, elevate decisively, and keep multi‑team efforts on track.
• Maintain cutsheets, as‑builts, validation results, and lessons learned, and contribute to the deployment playbook that lets the team scale.
• Provide operational support during and after deployments: incident response, troubleshooting, and break‑fix.

Skills & Experience

• Hands‑on data center network engineering and understanding of modern fabrics (EVPN/VXLAN, BGP, CLOS), having configured production infrastructure.
• You thrive in the field, equally comfortable pulling cable, configuring switches, and troubleshooting the optical layer, and you execute with whatever tooling is available.
• You troubleshoot methodically across physical and logical layers: OTDR traces, insertion loss, BGP sessions, and connectivity through complex topologies.
• You communicate clearly across technical and non‑technical teams, document well, and follow through.
• You learn fast and take ownership of ramping on new technology, and you'll travel 50 to 60% to onsite deployments.
• Bonus: AI fabric turn‑up experience. Configuration management and automation tooling. Vendor certifications.

Benefits

• Competitive salary and meaningful equity
• Join a fast‑growing pre‑series A company at the ground floor
• Health, dental, and vision benefits with 90% coverage for you and 50% for dependents
• Opportunities to participate in events across the cloud native community
• Fitness stipend, learning budget, and much, much more
