Own reliability at scale with us!

We are looking for a Senior SRE Engineer to join our infrastructure team and take technical leadership over production resilience. This role sits at the Senior level on our Cloud/Platform/SRE career path — reliability engineering with a heavy focus on metrics and production systems. You'll define SLIs and SLOs, lead incident response as commander, drive observability strategy end to end, and mentor cloud/platform engineers as you go.

You'll work closely with Product and Engineering, balancing speed, quality, and long-term reliability, while making the architectural calls that keep our systems resilient under load.

Responsibilities

Reliability & Incident Management

Lead incidents as commander: set and revise severity, and know when to mitigate first and diagnose later

Own the incident record and timeline standard, including the link between deployments and incidents

Communicate with stakeholders while an incident is active

Conduct blameless postmortems and drive toil identification and elimination as measured work

Observability

Implement the three pillars of observability (logs, metrics, traces) end to end

Design metrics and query strategy — recording rules, dashboard design that separates on-call needs from analyst needs

Define SLIs and SLOs for critical services, choosing the indicator that reflects user experience over the one that's easiest to measure

Design alerting systems — routing, escalation, deduplication, and alert fatigue reduction (multi-window burn-rate alerts)

Platform & Production Systems





Design workload health signals — liveness, readiness, and startup probes — and reason about workload lifecycle (SIGTERM handling, termination grace periods, connection draining)

Build runbook automation and self-healing systems to reduce operational toil

Contribute to CI/CD framework improvements and cost optimization initiatives

Technical Leadership

Make architectural decisions for reliability-critical systems

Mentor cloud/platform engineers

Influence technical direction on infrastructure and platform decisions

Requirements

5+ years of experience in SRE, Cloud, or Platform engineering roles

Profound knowledge of SRE principles and incident response practices

Profound knowledge of the observability stack: log aggregation and query design, metrics/dashboard design, and distributed tracing

Profound knowledge of Kubernetes cluster operations and workload objects (Deployments, StatefulSets, Jobs, DaemonSets) and their failure modes

Solid to profound knowledge of networking fundamentals: DNS as infrastructure, TLS certificate lifecycle, load balancing and reverse proxies

Hands-on experience with Infrastructure as Code (Terraform or equivalent)

Profound knowledge of process and OS-level architecture trade-offs as they apply to containers (immutable infrastructure, image strategy)

Scripting proficiency (Bash or Python)



for tooling and automation

Strong Git and collaborative workflow experience

Nice to Have

Experience with chaos engineering or failure injection programs

Exposure to multi-region or multi-cloud design trade-offs

Familiarity with service mesh implementations

Prior mentoring or technical leadership experience

Certifications such as Site Reliability Engineering (SRE) Foundation or Observability Foundation

Contributions to open-source observability or Kubernetes tooling
