What’s next? Backed by our $108M Series C, we’re doubling down on making APA the new standard for DevOps and MLOps, and everything in between.

Core values that hold us all together:

PRACTICE CUSTOMER OBSESSION. Focus on the customer journey and work backwards. Strive to deliver customer value and continuously solve customer problems. Listen to customer feedback, act, and iterate to improve customer experience.

LEAD. Take ownership and lead through action. Think and act on behalf of the entire company to build long-term value across team boundaries.

DEVELOP AND HIRE THE BEST. Strive to raise the performance bar by continuously investing in yourself, the team and by hiring the best possible candidates for every position. Drive towards personal development and professional growth, and mentor others to raise the collective bar.

EXPECT AND ADVOCATE CHANGE. Strive to innovate and accept the inevitable change that comes with innovation. Constantly welcome new ideas and opinions. Share insights responsibly with unwavering openness, honesty, and respect. Once a path is chosen, be ready to disagree and commit to a direction.

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.
• Release engineering: Extensive experience in automating releases, version control, and quality assurance.
• 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.
• Strong English fluency, both verbal and written.
• 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 in it 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.
