The Role

We’re looking for a Senior Technical Support Engineer who’s equal parts problem-solver, translator, and customer hero. You’ll be the go-to person when customers hit snags with Chainguard Images, digging into technical mysteries, keeping folks informed, and partnering with Engineering to squash bugs before they cause chaos.

This isn’t just "reset the password and move on" support: you’ll work on real, complex issues with modern tools (Docker, Kubernetes, GitHub, Helm charts, Terraform, etc.), make customers feel like superheroes themselves, and help shape how Chainguard delivers world-class support.

What You’ll Do

• Be the frontline agent: Triage, investigate, manage, and annihilate complex customer issues involving Chainguard Images.
• Escalate wisely: Engage the Engineering team when things get spicy.
• Communicate like a pro: Keep customers (and your SLAs) happy, informed, and impressed.
• Bridge the tech lingo divide: Explain things clearly to both code whisperers and non-tech humans.
• Document like a librarian: Create detailed write-ups of new issues and throw helpful Knowledge Base nuggets into the mix.
• Channel your inner detective: Prioritize your own queue, drive clarity in communication, and proactively guide issues to resolution.
• Speak up smartly: Push bugs, feature requests, and hidden gremlins up to Engineering and GTM teams.
• Learn, teach, repeat: Seek new challenges, share wisdom, and maybe teach someone your favorite GitHub ninja trick.
• Be there when it counts: Participate in an on-call rotation for after-hours, weekend, and holiday support.

What We're Looking For

• 5+ years supporting enterprise customers with a confident, calm approach.
• 3+ years under your belt with Linux, Docker, and Kubernetes (you dream in containers).
• Ability to deliver top-tier customer experiences with stellar written and verbal communication.
• Experience as a cross-functional harmony maker supporting teams across Engineering, Customer Success, and more.
• Comfortable in the DevOps warzone: CI/CD, Linux, GitHub, Helm Charts, Terraform, Open Source, and related tooling.
• Experience with AWS, Azure, or GCP; AWS EKS experience is a plus.
• Extra kudos if you’ve flirted with security frameworks, software supply chain security, or vulnerability scanning.
• Extra kudos if you bring CKA, CKAD, CKS, or KCSA certs and aspire to be a future Kubestronaut.
• Startup experience is a major plus.
• A curious soul who learns fast.
• Bachelor’s degree (STEM preferred) or equivalent real-world experience.

Benefits & Perks

• Flexible & Remote-First Culture: Work remotely with team meetup opportunities, bi-annual destination summits, and a monthly stipend for coworking spaces, phone, and internet costs.
• Equity: Receive stock options upon hire and promotion, with participation in secondary offerings and 10 years to exercise your options.
• 100% Covered Health Insurance: 100% coverage of health, vision, and dental insurance premiums for you and your dependents.
• Flexible Time Off: Take the time you need to recharge and reset.
• Paid Parental Leave: 18 weeks for birthing parents and 12 weeks for non-birthing parents, usable all at once or throughout your child's first year.
