Role overview

We’re looking for a Senior Software Engineer to join our Hosted team - the group responsible for enabling enterprise customers to run our platform inside their own infrastructure, often in regulated or air-gapped environments.

This role is hands-on and cross-functional. You’ll spend your time building tooling and automation to simplify deployment and upgrades, writing and maintaining infrastructure code, and working directly with customer engineering teams during onboarding and troubleshooting. A significant part of your work will involve automating tests and building a robust, secure release pipeline to ensure the reliability of every deployment.

You’ll also collaborate internally to ensure the platform is modular, testable, and resilient in diverse operating environments.

This is a great fit for someone who enjoys digging into systems, solving infrastructure challenges, and helping customers succeed with robust, secure deployments.

Requirements

Technical Skills

• Cloud proficiency: Strong familiarity with at least one major cloud platform (AWS, GCP, or Azure) — ideally, you’re confident navigating infrastructure across all three.
• Infrastructure as Code: Hands-on experience with Terraform is essential. You should be comfortable modeling and managing complex infrastructure in code.
• Programming expertise: Proficiency in Golang — this is our primary language for backend and tooling.
• CI/CD and release engineering: Familiarity with modern release workflows and tooling, including GitLab and GitHub. Experience designing or maintaining secure, reliable pipelines is a plus.
• Distributed systems troubleshooting: Solid diagnostic skills across OS, networking, containers, and transport layers. You should enjoy root-causing subtle issues in complex systems.
• Cloud-native deployment: Prior experience deploying and operating systems in secure or air-gapped environments is a strong advantage.

Soft Skills

• Clear and proactive communicator: You’ll regularly work across engineering teams and directly with enterprise customers — strong written and spoken communication is critical.
• Startup mindset: You thrive in ambiguity, adapt quickly, and prefer action over waiting for perfect certainty.
• Collaborative problem-solver: You bring a constructive, “how can we make this work?” attitude to technical and interpersonal challenges.
• Customer empathy: You understand the pressures our customers face, and aim to make their experience as smooth and successful as possible.

What's init for you?

• Join a fast-growing, cutting-edge company that’s redefining cloud-native automation and optimization.
• Work with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology.
• Enjoy a flexible, remote-first work environment with opportunities to travel and engage with customers worldwide.
• Competitive compensation package, equity options, and extensive benefits.
• Short feedback loop. We have an obsession with customer satisfaction. The ship features fast and gets instant feedback. Feature projects tend to be completed in 1 to 4 weeks, depending on the scope.
• 10% time to focus on self-improvement or personal projects.
• Monthly salary from 6000-9000 (gross) depending on the level of experience.
