Tooling Engineer

Help build the DX for the cloud rebuilt from scratch — CLIs, SDKs, and integrations that make millions-of-users-on-a-few-servers feel effortless.

We usually respond within a day.

The cloud is broken: it’s wasteful, slow, awfully expensive, and burdened with legacy tech that wasn’t built for today’s workloads. At Unikraft we’re building a generational, truly millisecond-native, extremely scalable cloud platform that provides exponentially higher efficiency. Are you bored with your current job? Want to push the boundaries of what’s possible in the cloud to the absolute limit?

Our team consists of some of the best systems, performance, and security geeks out there, and is backed by top investors with category leaders as our customers. We believe a focused team of exceptional people, moving fast with conviction, can rebuild the cloud from first principles and make extreme efficiency (e.g., millions of users on a few servers) available to everyone.

What you’ll do and why it’s career defining

This is a rare opportunity to design the developer experience for a generational cloud platform — the CLIs, SDKs, integrations, and dashboards that every user will touch the moment they meet Unikraft. As a Tooling Engineer, you won’t be bolted on to the side of the platform. You’ll be building the surface through which developers actually use it, and the glue that connects it to the ecosystems they already live in: Terraform, Kubernetes, Docker, GitHub Actions, and beyond.

You’ll work closely with world-class systems engineers, with direct ownership over the tools, integrations, and self-serve experiences that turn raw platform capability into something developers love. If you care deeply about craft in developer tooling, enjoy moving fluently between Go, systems-level code, and product surfaces, and want your work to have a measurable impact on a fast-growing platform, this is your role.

What You’ll Own

• Developer Tooling & SDKs
  • Build and maintain developer tooling across the platform, including CLIs, TUIs, and SDKs.
  • Develop and improve integrations such as Terraform, Kubernetes, Docker, and GitHub Actions.
  • Work with APIs and integration points to make the platform feel native inside existing developer workflows.
• Dashboard & Self-Serve Experience
  • Contribute to the frontend and backend systems powering the dashboard and overall self-serve experience.
  • Help deploy and monitor all our external-facing services — from our website, to our dashboard, to our packaging and installation infrastructure.
• Platform & Prototyping
  • Work on lower systems-level components that directly interface with our low-level platform.
  • Prototype new platform capabilities such as sandboxed environments and remote builds.

What We’re Looking For

• Solid engineering fundamentals and the ability to contribute across backend and tooling, specifically in Go.
• Interest or experience in building developer tools, CLIs, or system utilities.
• Experience working with APIs and integrations.
• Ability to manage complexity and adapt to a fast-moving platform.
• (BONUS) Experience contributing to open source projects.
• (BONUS) Experience with C or systems programming.
• (BONUS) Familiarity with cloud-native tooling such as Kubernetes, Terraform, and CI/CD systems.

Why you will love this team

• Elite founders, real access: Work directly with globally recognized deep tech founders who’ve spent careers at the frontier of systems and cloud research. You’ll learn more here in a year than most people do in five.
• World-class product: A category-defining technology that sparks genuine excitement with developers.
• Zero bureaucracy: Founder-led, product-obsessed, and deeply technical.
• Fully Remote, Fully Flexible: Work from your favorite place, at your most productive times.
• Retreats, Game Nights and More: Fun-focused team retreats and other events to recharge and build great relationships.
• The Standard Stuff: Competitive salary, 6 weeks of vacation, development opportunities.
