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 resolve complex customer issues involving Chainguard Images.
• Escalate wisely: Engage the Engineering team when technical issues require deeper investigation.
• Communicate effectively: Keep customers informed and impressed while maintaining SLA commitments.
• Bridge the technical divide: Explain technical details clearly to both software engineers and non-technical stakeholders.
• Document knowledge: Create detailed write-ups of new issues and publish Knowledge Base articles.
• Drive resolution: Prioritize your own queue, maintain clear communication, and proactively guide issues to resolution.
• Advocate for improvements: Escalate bugs, feature requests, and edge cases to Engineering and Go-To-Market teams.
• Continuous learning & sharing: Seek new challenges, share technical knowledge, and mentor team members.
• On-call support: Participate in an on-call rotation for after-hours, weekend, and holiday support.

What We're Looking For

• 3+ years of experience supporting enterprise customers with a confident, calm approach.
• 2+ years of hands-on experience with Linux, Docker, and Kubernetes.
• Excellent written and verbal communication skills.
• Experience working cross-functionally across Engineering, Customer Success, and product teams.
• Strong familiarity with DevOps environments: CI/CD, Linux, GitHub, Helm Charts, Terraform, and open source ecosystems.
• Experience with public cloud providers (AWS, Azure, GCP); AWS EKS experience is a plus.
• Bachelor’s degree in a STEM field or equivalent real-world technical experience.

Bonus Points

• Familiarity with security frameworks, software supply chain security, or vulnerability scanning.
• Kubernetes certifications (CKA, CKAD, CKS, KCSA).
• Prior experience working in high-growth startup environments.

Benefits

• 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 a 10-year exercise window and opportunities to participate in secondary offerings.
• 100% Covered Health Insurance: 100% company-paid health, vision, and dental insurance premiums for you and your dependents.
• Flexible Time Off: Unlimited PTO policy to recharge and reset.
• Paid Parental Leave: 18 weeks for birthing parents and 12 weeks for non-birthing parents.
