Job summary

WarpBuild is hiring a senior network engineer to design, deploy, and operate its datacenter network, from edge to spine, across colocated sites in India. You will own network design, deployment, automation, and operations, working directly with founders and platform engineers.

You will lead site turn-ups, manage config as code, and build monitoring and capacity planning while handling remote hands and vendors. A strong background in BGP, ECMP, and PoP growth is essential.

Qualifications

• 7+ years in network engineering, production datacenter/cloud/service provider networks.
• Experience building a datacenter or PoP network from ground up at least once.
• Strong knowledge of BGP, ECMP, leaf-spine fabrics, link aggregation and fast convergence.
• Experience running an internet edge: transit and peering turn-ups, IRR and RPKI, and traffic engineering.
• Production experience with major switching platforms (Arista/Juniper/Cisco or SONiC).
• Strong automation skills with Python and Ansible or similar; configs in Git.
• Good knowledge of optics, DAC/fiber cabling, structured cabling and cross-connects.
• Comfort with Linux CLI and Linux network stack.
• Clear written English; able to follow procedures from sites with no on-site staff.

Responsibilities

• Design, deploy and operate leaf-spine datacenter networks, edge and out-of-band.
• Run the internet edge: BGP with transit providers and peers, routing security, DDoS protection.
• Lead site turn-ups from planning to handover: cabling plans, device staging, validation and testing.
• Manage network configuration as code with a source of truth, templates, automated checks and zero-touch provisioning.
• Direct remote hands, cabling vendors, carriers and hardware vendors; sites with no on-site staff.
• Build monitoring and alerting for the network; use data for capacity planning.
• Work with platform engineers on Linux host networking for virtualization stack.
• Write designs, procedures and runbooks for the team; keep documentation updated.
• Participate in on-call rotation.

Job description

Remote (India) Full-time

Build WarpBuild's datacenter network from empty racks to production traffic. Run it and grow it to new sites.

WarpBuild runs fast CI runners for GitHub Actions. We are building our own bare-metal infrastructure in colocation datacenters. We are a small team, and every engineer owns a large part of the product.

You will be our first network engineer. This is a hands‑on role with full ownership of design, deployment, automation and operations. You will work directly with the founders and the platform engineering team.

What you'll do

• Design, deploy and operate leaf-spine datacenter networks, including the edge and the out-of-band network.
• Run the internet edge: BGP with transit providers and peers, routing security, and DDoS protection.
• Lead new site turn-ups from planning to handover: cabling plans, device staging, validation and acceptance testing.
• Manage network configuration as code, with a source of truth, templates, automated checks and zero‑touch provisioning.
• Direct remote hands, cabling vendors, carriers and hardware vendors. Our sites have no on‑site staff.
• Build monitoring and alerting for the network. Use the data for capacity planning.
• Work with platform engineers on Linux host networking for our virtualization stack.
• Write the designs, procedures and runbooks that the rest of the team relies on.
• Take part in the on‑call rotation.

What you’ll bring

• 7+ years in network engineering, mostly on production datacenter, cloud or service provider networks.
• Experience building a datacenter or PoP network from the ground up at least once.
• Strong knowledge of BGP, ECMP, leaf-spine fabrics, link aggregation and fast convergence.
• Experience running an internet edge: transit and peering turn‑ups, IRR and RPKI, and traffic engineering.
• Production experience with at least one major switching platform, such as Arista, Juniper, Cisco or SONiC.
• Strong automation skills with Python and Ansible or similar tools. Config lives in Git.
• Good knowledge of the physical layer: optics, DAC and fiber cabling, structured cabling and cross‑connects.
• Comfort on the Linux command line and a working understanding of the Linux network stack.
• Clear written English. A technician who has never seen the site can follow your procedure.

Nice to have

• Experience at a cloud provider, CDN, carrier or internet exchange.
• NetBox or another network source of truth.
• Streaming telemetry and flow monitoring, such as gNMI and sFlow.
• KVM and virtual machine networking, NAT at scale, nftables.
• IPv6 in production.
• Participation in SANOG, INNOG, APNIC or a similar operator community.

What we offer

• High equity and compensation.
• Full ownership of the network at an early stage of the company.
• Remote work from anywhere in India.
• Occasional international travel for site builds.

About the interview

Four rounds, each up to 60 minutes: 50 minutes technical, 10 minutes Q&A. Use your own computer and tools. AI tools are allowed. Each round is a screen share with video.

• Network design (60 min): Design a leaf‑spine fabric and internet edge for a real site. Focus on tradeoffs, failure domains and growth.
• Troubleshooting (60 min): Debug a broken network. Find the cause, fix it, and explain how to prevent it.
• Automation (60 min): Write working code for a network task: config generation from a source of truth, or a validation check.
• Team fit and aptitude (60 min): Past builds, work with vendors and remote hands, written communication, and working in a small team.

Each round is a knockout. An offer is rolled out in person over a final 30 minute conversation.
