What You'll Do

• Production Operations & Incident Response

• Own platform reliability across global UC infrastructure, driving incident response and the overall reliability strategy for your subsystem rather than resolving issues in isolation.

• Triage and resolve the hardest issues — service restarts, hung processes, infrastructure failures — and act as the senior escalation point for the NOC and for other engineers when frontline teams hit their limit.

• Execute and improve the unglamorous but essential work: scheduled maintenance, certificate renewals, log rotation — and redesign these processes so failure is prevented systemically, not handled case by case.

• Lead blameless post-mortems that produce real follow-through, and sign off on the corrective actions that come out of them.

• Cross-Team Collaboration

• Work directly with Support, Sales, Sales Engineering, NOC, Professional Services, and Engineering teams across 8x8 — this team sits at the operational center of the company.

• Translate production events into clear, business-readable communication under pressure; stakeholders across the org depend on your judgment during incidents.

• Feed operational insight back into engineering — turning recurring failures and patterns into actionable bug reports, platform improvements, and influence over the architectural roadmap.

• Work closely with technical leads to align reliability and automation work with broader engineering goals, and help focus discussion on what matters most.

• Reliability Engineering & Automation

• Identify recurring manual work and build automation to eliminate it — we treat toil as a bug, not a requirement.

• Drive design for the tooling and automation in your domain; anticipate how a change in one component impacts others and account for adjacent domains in your designs.

• Understand the limits of our existing tools — and recognize when a problem exceeds those limits and deserves the effort of building a new one.

• Take on large-scale technical debt and refactoring across the subsystem, and contribute to the team's coding methodologies and best practices.

• Participate in 2-week sprint cycles to deliver automation, tooling improvements, runbook development, and infrastructure initiatives from a structured backlog. Own the functional specifications for large features and sign off on test plans.

• Address security issues as they arise — CVEs, misconfigurations, access control gaps — treated as first-class work alongside incident response.

• Define and track SLIs, SLOs, and SLAs to drive honest, data-driven conversations about where reliability investment is needed.

• Build and maintain dashboards (Grafana, OCI Log Analytics) that give the team genuine signal; tune alerting to eliminate noise — a high-noise on-call is itself a reliability failure.

• Leverage AI-powered tooling to accelerate diagnostics and reduce cognitive load at scale.

• Technical Leadership & Mentorship

• Provide technical leadership for projects involving 1–2 other engineers.

• Consistently mentor more junior engineers; be the person other developers seek out for constructive, insightful feedback.

• Frequently and actively share knowledge — of your own work, of areas you've worked in, and of obscure corners outside your immediate context — and encourage others to do the same.

• Run workshops, contribute to how-to guides, present at demos, and contribute to the team's presentation portfolio.

• On-Call & Coverage

• Shared on-call rotation, approximately 1 week per month — same expectation for every engineer on the team.

• Escalation is always an option and is encouraged; you are expected to drive the response, set the pace for others, and know when to pull people in — not to hero it alone.

• Tooling: PagerDuty for alerting, Jira for tracking, OCI Log Analytics and Grafana for diagnostics.

• What We're Looking For

• Required

• 6+ years in a site reliability, platform operations, or infrastructure engineering role — you have run production systems at scale and have a track record of driving, not just maintaining.

• Mastery of Linux systems administration: multi-service distributed systems, log reading, systemctl, network diagnostics, no GUI required.

• Deep hands-on experience with at least one major cloud provider (OCI, AWS, GCP, or Azure) — compute, storage, IAM, networking fundamentals.

• Strong on-call experience: calm under pressure, fast triage, clear communication during an incident, and the judgment to lead a multi-party response.

• Scripting in Python or Bash — enough to automate a task, parse logs, hit an API, and refactor someone else's tooling without breaking it.

• Strong incident response discipline: structured thinking, stakeholder communication, post-mortems that actually say something and drive follow-through.

• Solid command of SRE concepts: SLIs, SLOs, error budgets, toil measurement — and the ability to use them to steer investment decisions.

• Demonstrated technical leadership: driving designs, owning large features end to end, and mentoring other engineers.

• AI-forward mindset — you use AI tools as a core part of how you work, not as a novelty.

• Preferred

• Experience with Oracle Cloud Infrastructure (OCI) — compute, networking, Log Analytics, Object Storage.

• Familiarity with VoIP and SIP infrastructure — registration, trunking, call signaling; this is a UC platform and that knowledge matters.

• Knowledge of observability tooling: Prometheus, Grafana, PagerDuty, OCI Log Analytics.

• Experience with Ansible for configuration management and deployment automation.

• Exposure to infrastructure migrations at scale in multi-tenant SaaS environments.

• 8x8 is proud to provide equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability or genetics.
