## Job description

Life at Plume

At Plume, we believe that technology isn't about moving faster, it's about making life’s moments better. Which is why we’ve built the world's first, and only, open and hardware-independent service delivery platform for smart homes, small businesses, enterprises, and beyond. Our SaaS platform uses WiFi, advanced AI, and machine learning to create the future of connected spaces—and human experiences—at massive scale.

We now deliver services to over 60 million locations globally and have managed over 3 billion devices on our platform. We’re expanding rapidly, pioneering a new category, and we achieved our Series F funding in just four years. Our customers include many of the world's largest Internet Service Providers (ISPs) who look to Plume to help them evolve their smart home offerings while gleaning insights from their own data.

With a bias for action and a love for being trailblazers, the team at Plume embodies a combination of relentless curiosity and imaginative innovation. We challenge ourselves to think in ways that other companies don't, work to do what should be done (rather than what can), and if we can’t do it exceptionally well, we don’t do it. It’s how we've assembled a team of world-class builders, thinkers, and doers. And it’s how we’re reinventing what’s possible every day.

Role Summary:

We're looking for an experienced Engineering Manager to lead our NOC L2 team. This role combines people leadership, operational ownership, and technical depth — you'll manage a team responsible for triaging, investigating, and resolving escalated network and platform incidents, while also driving process improvements that reduce incident volume and improve response times over time.

You'll be a key operational leader, responsible not just for keeping the team running day-to-day, but for building the systems, runbooks, and culture that make incident response faster, calmer, and more effective across the organization.

Responsibilities:

- Lead, mentor, and grow a team of NOC L2 engineers responsible for escalated incident triage and resolution
- Own on-call rotation structure, escalation policies, and incident response processes for the L2 team
- Drive root-cause analysis and post-incident reviews, ensuring learnings translate into concrete process or system improvements
- Partner with Engineering, Infrastructure, and Product teams to reduce recurring incident classes and improve platform reliability
- Establish and refine runbooks, playbooks, and operational documentation to speed up incident resolution and reduce reliance on tribal knowledge
- Monitor and report on key operational metrics (MTTD, MTTR, incident volume, escalation rates) to leadership
- Manage team schedules, coverage, and on-call rotations to ensure 24/7 operational readiness
- Hire, coach, and develop engineers on the team, conducting regular 1:1s, performance reviews, and career development planning
- Act as an escalation point for the most critical or ambiguous incidents, providing hands-on technical guidance when needed
- Collaborate with L1 NOC leadership to ensure smooth escalation handoffs and continuous improvement of triage criteria
- Drive a culture of blameless postmortems and continuous operational learning

Qualifications:

- 4+ years of experience in network operations, infrastructure, or site reliability roles, with at least 2+ years in a people management or team lead capacity
- Strong understanding of networking fundamentals (TCP/IP, DNS, routing, firewalls, VPNs) and troubleshooting methodology
- Proven experience owning incident response processes, including on-call rotation design and escalation management
- Experience with monitoring, alerting, and observability tools (e.g., Grafana, Prometheus, Datadog, PagerDuty, Splunk)
- Strong track record of driving operational improvements that measurably reduce incident volume or resolution time
- Excellent communication skills — able to translate technical incidents into clear updates for both technical and non-technical stakeholders
- Comfortable operating in a 24/7 operational environment, including managing coverage across shifts and time zones

Nice-to-Haves:

- Experience in telecom, ISP, networking hardware, or connected-device industries
- Familiarity with cloud infrastructure (AWS, GCP, or Azure) and container orchestration (Kubernetes, Docker)
- Experience with automation/scripting to reduce manual operational toil (Python, Bash, or similar)
- Prior experience scaling a NOC or SRE team through significant growth
- ITIL or similar operational framework certification/experience

## About Plume
