Job Summary

As a Senior Cloud Support Engineer at Platform9, you provide concentrated, account-focused technical support to our most critical enterprise customers as part of Business Critical Services. Acting as the dedicated support engineer for a set of premium accounts, you bring deep, multi-domain troubleshooting expertise to the issues that matter most: driving fast, durable resolution of complex L2/L3 cases, leading high-severity incident response, and supporting VM migration and workload-mobility efforts across OpenStack and Kubernetes environments.

This is the senior individual-contributor level in support. You own the hardest problems on our highest-stakes accounts, set the standard for root cause analysis, and mentor the broader support team, while partnering closely with Enterprise Technical Advisors (ETAs), Engineering, and Product. It is also a strong platform for engineers who want to grow toward Enterprise Technical Advisor or Solutions Architect roles over time.

Essential Functions

Senior Cloud Support Engineers work with Platform9 customers and internal teams by providing expertise in the following areas:

• Serve as the designated support engineer for a set of Business Critical (premium) accounts, owning the technical support experience and outcomes for those customers.
• Own and drive resolution of complex L2/L3 technical issues to fast, durable closure against premium SLAs, with strong case hygiene (repro steps, logs, timelines, customer impact, workaround status).
• Lead Sev1/Sev2 incident response, gathering diagnostics, scoping customer impact, coordinating cross-team resolution, and driving root cause analysis to completion.
• Troubleshoot VM migration and workload-mobility issues, including live-migration failures, volume detach/attach inconsistencies, and VMware-to-PCD (vJailbreak) edge cases; distinguish control-plane vs. data-plane behavior and API latency vs. backend execution.
• Execute the technical work of account "get-well" plans on at-risk accounts, driving open issues to closure against defined exit criteria.
• Support self-hosted upgrade and maintenance windows, including readiness checks and collaborative troubleshooting through the change window.
• Perform environment health checks and maintain account runbooks, RCAs, and knowledge base content.
• Surface recurring defects and workaround patterns into structured product feedback for Engineering and Product.
• Partner with Enterprise Technical Advisors on account context and priority, and co-deliver customer-facing technical reviews as needed.
• Mentor and uplevel L1-L3 Cloud Support Engineers, and set the standard for diagnostics and RCA quality across the team.
• Compile and deliver root cause analyses (symptoms, contributing factors, corrective actions, prevention), coordinating internally for completeness and clarity.

• VM migration and workload mobility (live migration, storage detach/attach, state reconciliation; VMware-to-PCD / vJailbreak experience is a plus).
• Networking (TCP/IP, routing/switching fundamentals, VLANs, MTU/jumbo frames, LACP/bonding, DNS/DHCP; familiarity with overlays like VXLAN/EVPN is a plus).
• Storage/infrastructure integrations (Ceph concepts, iSCSI/NFS fundamentals, CSI drivers, storage performance and latency troubleshooting).
• Automation/Infrastructure as Code (Terraform/Ansible, Git-based workflows, scripting with Bash/Python).
