About this role.
Tailscale is hiring a Customer Reliability Engineer to own high-severity post-sales technical escalations through resolution or a complete engineering handoff. The role combines enterprise technical support, networking troubleshooting, customer communication, incident investigation, and code-level debugging. The engineer will gather logs, reproduce difficult defects, identify systemic patterns, and create evidence-backed bug reports and runbooks. Candidates need at least four years of relevant SaaS or infrastructure escalation experience plus strong knowledge of VPNs, overlay networking, systems administration, cloud infrastructure, and Go or Python scripting.

Sample interview questions
I would first establish impact, scope, timeline, and immediate mitigations while keeping the customer informed. I would collect relevant logs, timestamps, versions, network topology, and reproduction details, then test leading hypotheses systematically. If engineering involvement is required, I would deliver a concise handoff containing a reproducible case, evidence, ruled-out causes, impact assessment, and recommended owning team.
I would verify node status, client versions, DERP relay usage, UDP reachability, firewall rules, NAT behavior, DNS resolution, and relevant routing configuration. I would inspect logs and packet-level evidence to determine whether direct UDP hole punching is failing and whether traffic is correctly falling back to relays. I would then isolate whether the issue is endpoint, local network, firewall, or service related and document the findings clearly.
An actionable report includes the customer impact, exact environment and version matrix, timestamps, identifiers, logs, reliable reproduction steps, expected versus actual behavior, and investigation findings. It should distinguish facts from hypotheses and identify what has already been tested or ruled out. The goal is to let an engineer begin debugging without repeating discovery work.
I acknowledge the impact, set clear expectations, and explain the investigation plan in plain language. I avoid speculation, provide regular updates even when there is no final answer, and summarize confirmed findings and next steps after the call. This builds trust while allowing the technical investigation to proceed with discipline.
I would begin by reproducing the behavior where possible and collecting relevant runtime data, including CPU and heap profiles with pprof. I would inspect goroutine states, contention, allocation patterns, and blocking operations to identify likely bottlenecks or leaks. I would correlate those findings with logs, request patterns, and network behavior, then provide engineering with the profiles, analysis, and a minimal reproduction.

About the Role
If you’re passionate about solving complex technical problems and helping build trust between customers and engineering, this is the role for you. We’re seeking a motivated Customer Reliability Engineer to join our team. You’ll take ownership of our most complex, ambiguous customer escalations, solving issues where the root cause is not always obvious. You will work these issues to resolution or alternatively a fully-documented handoff that engineering can act on without delay.
As a Customer Reliability Engineer, you’ll partner closely with the Customer Success Team, Support Team, and Product/Engineering to close the gap between “customer has described a problem” and “engineering has what it needs to fix it.” This role reports directly to the Customer Reliability Engineer Team Lead.
Key Responsibilities
- Own high-severity, post-sales technical escalations from intake through resolution or engineering handoff. This includes deep-dive investigations and reproduction of difficult-to-isolate bugs.
- Get on calls with customers, pull logs, and communicate with the customer about leading theories.
- Build engineering handoff packages that require minimal follow-up questions: reproducible case, log evidence (timestamps, node IDs), version matrix, impact scope, what’s already been ruled out, and a proposed engineering team to own the fix.
- File and track issues for confirmed bugs, keeping the ticket/issue link intact so engineering retains full customer context.
- Monitor for patterns across escalations to catch recurring or systemic issues early; translate what you learn into product improvements, tooling, and runbooks that raise the technical bar for the whole Support org.
- Partner with Support, CSE, and Product/Eng, while staying within this team’s scope.
What We Are Looking For
- 4+ years in a technical support or escalation role at a SaaS or infrastructure company, with demonstrated ownership of escalated/enterprise-tier accounts.
- A genuine problem-solver who gets energy from untangling hard, ambiguous technical issues
- Comfortable owning a live, high-stakes customer call: staying calm, building trust, and communicating clearly with a frustrated or technical customer under pressure.
- Hands-on networking experience in production or homelab environments: TCP/IP, routing, DNS, firewalls, NAT, VPNs, load balancers.
- Deep familiarity with overlay networking concepts — WireGuard, UDP hole punching, STUN — and comparable VPN/networking products.
- Code-level debugging capability: can read Go source, reason about goroutines/locks/channels, read pprof CPU/heap profiles, and understand network interface semantics.
- Comfortable with infrastructure concepts: cloud IaaS, CI/CD pipelines, containerized applications, and Kubernetes debugging.
- Strong systems administration skills as well as troubleshooting across Linux, macOS, and Windows.
- Track record of independently building reproducible test cases and clear, evidence-backed bug reports engineering can act on directly.
- Strong technical storytelling: able to distill highly technical, ambiguous issues into clear narratives for both engineers and non-technical stakeholders.
- Investigative mindset; curious to analyze root cause, and evaluate all options to get customers to the best solution
- Proficiency with programming/scripting in Go, Python, JSON
- Experience with packet-level analysis
