Infrastructure Software Engineer

Join our mission We're proud to work with many incredible companies, accelerating their ability to build their products. We've spent years watching talented engineering teams lose momentum to the same frustrating bottleneck: waiting. Waiting for CI to finish. Waiting for builds to complete. Waiting for tests to run. After experiencing this pain firsthand at companies of every size, we set out to build the developer infrastructure platform we'd always wanted to use. Something that would seamlessly integrate with our workflows and the tools teams already love—but make everything dramatically faster and more cost-effective. Today, we're already accelerating hundreds of companies around the world, helping them ship features instead of waiting for infrastructure. We've built something that feels almost magical in its simplicity: change your runs-on line, mount your toolchain cache directory and suddenly your builds are 5x faster. About the role Namespace's approach is low-friction, designed for immediate integration into existing developer toolchains, empowering teams to experience tangible results within just five minutes. With an end-to-end stack optimized for high performance—including compute, memory, storage, and networking—Namespace delivers capabilities and efficiencies unmatched by traditional cloud providers. Own the software that drives our hardware. You'll write the control planes, automation, and observability that keep our global fleet fast, efficient, and reliable, while charting a path to scale that continues to increase the number of "machines under management" per engineer. Our culture We're looking for people with grit—people who push through ambiguity, take ownership, and keep going when things get hard. You're deeply curious, driven to understand how things work and how they can be improved. Most importantly, you have a strong bias to execution: you don't wait for perfect conditions, you ship, learn, and iterate quickly. If you care about building, moving fast, and making real impact, you'll fit right in. What you'll do Manage and automate the fleet – build services for provisioning, health checks, upgrades, and incident remediation Uphold reliability – embed observability, graceful degradation, and rollback paths into every layer you touch Architect the network – design and evolve a high-throughput, low-latency fabric tailored to our high performance use-cases Ship software, not scripts – develop clean, testable code (mostly Go) that treats our fleet like a first-class API Drive efficiency – improve utilization and power-to-performance ratios so capacity grows slower than usage Partner across the stack – work with product, infra, and platform teams to scope and deliver features like storage-aware scheduling, cache volumes, and other developer-facing features What we're looking for Proven experience engineering large-scale infrastructure - writing the software that runs fleets, not just operating existing hyperscalers Depth in network architecture, data-center design, and performance tuning Hands-on time deploying and managing compute hardware at scale (servers, switches, etc) Fluency with modern orchestration and automation tooling (Kubernetes, Terraform, Ansible - plus the judgment to know when to build vs. buy) A track record of delivering reliable systems and measurable efficiency gains You can expect: Competitive salary and stock options Flexible working hours Market-leading parental leave Life at Namespace Labs: We pride ourselves in being a small team of experts that can achieve a lot. We balance our long-term vision with short-term pragmatism. We believe in being fully transparent internally on how decisions are made, on how the company is doing, and we use that information to drive our decisions.
