Senior Platform Engineer

We're expanding our Platform Engineering team to build out observability and incident response from the ground up. We have a cloud architecture supporting hundreds of services, but our visibility into system health, performance, and failures is largely manual today. We need someone who can architect and implement a modern observability stack-not just monitor it.

This is a chance to make an immediate impact: you'll design logging, metrics, and tracing patterns that the entire engineering organization depends on. You'll reduce toil, surface actionable signals, and turn chaos into clarity.

You'll report to our Head of Platform Engineering as an individual contributor and will have the autonomy to move quickly, make opinionated decisions, and set standards for how we operate.

What Success Looks Like

• Phase 1: Audit & Plan - Map current gaps, propose tooling & rollout strategy, get buy-in.
• Phase 2: Foundation - Select tools, document decisions, pilot agents on 2-3 services.
• Phase 3: Standardize - Structured logging patterns, baseline dashboards, incident routing, alerting.
• Phase 4: Prove It - Demonstrate reduced MTTD and MTTR, fewer manual escalations, documented runbooks, team trained on tooling., Observability Architecture & Implementation
• Design and deploy a logging, metrics, and APM stack that scales with the organization
• Establish agent configuration best practices (New Relic, OpenTelemetry, or alternatives)
• Create structured logging patterns and cardinality management strategy
• Implement distributed tracing to understand latency and failure paths across services

Incident Management & Response

• Evaluate and select incident management platform (we're not locked into any vendor)
• Build alerting policies that surface real signals without drowning teams in noise
• Develop incident triage, escalation, and communication workflows
• Create runbooks and post-incident analysis templates

Automation & Toil Reduction

• Identify manual work in today's incident response and automate it away
• Build dashboards, alerts, and self-service tools so teams don't need platform team involvement for basic troubleshooting
• Codify monitoring and alerting as infrastructure (IaC), At WeightWatchers, we prioritize the security of our candidates. To ensure you are communicating with a legitimate representative of our team, please keep the following security standards in mind:
• Verified Email Domain: All official correspondence from our recruiting team will originate from an @ww.com email address.
• Live Engagement: Our hiring process requires live interaction. We do not conduct interviews or extend employment offers solely through text message, chat apps, or automated email-only exchanges.
• Financial Integrity: WeightWatchers will never ask for any form of payment from a candidate. We will never send you a check with instructions to purchase equipment or "start-up kits" on our behalf.
• Secure Data Collection: Sensitive personal information (such as banking or identity tax info) is only requested through our official, secure onboarding portal after a formal offer has been extended, never during the interview phase.

Required

• 5+ years in SRE, platform engineering, or similar infrastructure role
• Deep expertise in at least one observability domain (metrics, logging, tracing, or APM)
• Experience with agent configuration and instrumentation (New Relic, Datadog, OpenTelemetry, or equivalent)
• Track record of building (not just maintaining) monitoring/alerting systems
• Comfortable making opinionated architectural decisions with incomplete information
• Strong systems thinking-you understand tradeoffs between managed vs. open-source, complexity vs. coverage

Strongly Preferred

• AWS and containerized environments (EKS, Docker)
• Infrastructure-as-Code (Terraform, CloudFormation)
• Kafka or async message queues (understanding log/metric pipeline architecture)
• RDS experience (database monitoring, slow query logs)
• Open-source observability stack (Prometheus, ELK, Grafana, Jaeger)

Cultural Fit

• You move fast and are comfortable with ambiguity-greenfield projects are exciting, not daunting
• You're opinionated but pragmatic-you'll push back on bad ideas and compromise when needed
• You think like a builder, not a ticket-taker
• You communicate clearly: you can explain technical decisions to non-technical stakeholders
