FreeWheel, a Comcast company, is looking to improve the quality of service (QoS) in its software engineering department. The goal is to ensure a resilient, reliable, and learning-focused culture by resolving incidents quickly, implementing long-term improvements, and maintaining consistent high-quality service across global operations and diverse customer needs.

Requirements

  • 6+ years of technical experience in software engineering, site reliability, or production operations.
  • Proven track record of managing the full software development lifecycle (SDLC), from requirements gathering to production release.
  • Hands on understanding of full stack components: Frontend/UI frameworks and client experience
  • Hands on understanding of full stack components: APIs & service layers
  • Hands on understanding of full stack components: Database layer (SQL/NoSQL, data modeling, performance tuning)
  • Hands on understanding of full stack components: Backend servers and distributed systems
  • Hands on understanding of full stack components: Big data & ETL pipelines (batch and streaming)
  • Strong knowledge of incident management (PagerDuty, Jira, Datadog, Splunk, ServiceNow).

Responsibilities

  • Own the Escalations lifecycle within Engineering, from the beginning through resolution.
  • Lead root cause analysis (RCA) sessions that dig deeper than symptoms and deliver long-lasting fixes.
  • Facilitate retrospectives and follow-ups, turning lessons learned into clear improvement plans.
  • Define and track metrics (incident frequency, resolution times, client impact), and make them visible through dashboards and reports.
  • Partner with teams to strengthen systems through tooling, automation, and platform hardening.
  • Keep a cross-platform perspective (TV, Data, Beeswax, Strata) to spot patterns and systemic issues.
  • Collaborate with Engineering (Tier 2/3) to resolve incidents quickly and share learnings across teams.

Other

  • Combine deep technical expertise with strong collaboration and communication skills.
  • Split your time between technical ownership and cross-functional collaboration.
  • Act as the single voice for Engineering in incident management, making sure communication is consistent and clear at all levels.
  • Partner with Operations (Tier 1) to fine-tune escalation paths and help reduce unnecessary hand-offs.
  • Work closely with the COO team to analyze client impact and provide crisp, timely updates during incidents.
  • Confidence to dive deep with engineers while also translating technical details into clear business context for executives and clients.
  • Experience operating in global, multi-time-zone environments with diverse customer and platform needs.
