Software Engineer in Infrastructure

The Role

We’re looking for a Network Software Engineer (Net SWE) to build software that makes network operations safe, scalable, and boring — even as we launch new data centers and expand fast.

This is not a “write scripts for configs” role: you’ll build the tooling and services that sit between the network core (switches/ports/VLANs, traffic processors) and the cloud platform on top, using open source where it fits and building the missing pieces where it doesn’t.

Responsibilities

• Build and maintain services and tooling that automate the network lifecycle: day-0 provisioning, day-N changes, drift detection, and operational verification
• Make network changes safe and transparent: CI/CD workflows, diff/review tooling, staged rollouts/rollbacks, audit trails, and guardrails
• Develop observability systems that scale across many sites: telemetry pipelines, signal quality, and tooling that shortens incident investigations
• Close “last mile” gaps between the network and the platform: integrate source-of-truth data, expose APIs, and build reliable automation around it
• Collaborate closely with network engineers and SREs to turn real operational pain into product-quality tooling

Requirements

• 5+ years of professional software engineering experience (or equivalent practical background)
• Strong coding skills and ownership mindset: you can ship and operate reliable services
• Proficiency in Go or readiness to switch; Python is also welcome (other languages can be useful for OSS debugging/fixes)
• You don’t have to be Network expert but we expect you to have interest in infrastructure and/or network
• Bonus
• Background in networking (ex-network engineer, CCNP/education, DC networking exposure) or strong interest and proven ability to learn fast
• Experience building automation/infra tooling: CI/CD, Ia C, testing/staging environments, or “network-as-code” style workflows
• Low-level networking / datapath experience: e BPF/XDP, DPDK, kernel networking, traffic processing systems
• Experience designing high-load services and observability platforms (metrics/logs/traces, alerting, regression detection)
• Contributions to open source or experience extending/debugging OSS components in production environments
• Staff Engineer Expectations
• Manage large-scale projects involving multiple stakeholders
• Break down complex tasks and guide both their own work and that of more junior colleagues
• Be experts in specific technologies and write high-quality code that can serve as a reference
• Assess task priority and focus on high-impact work, avoiding low-value efforts
• Have strong architectural thinking and contribute to system design
• Be involved in hiring and actively contribute to interviews
• Be willing to share knowledge and mentor others
