Responsibilities
- Define and evolve workload safety standards for Affirm’s Amazon EKS fleet, including resource settings, workload isolation, placement, disruption tolerance, and graceful termination.
- Own standards end to end through research, prototyping, early-adopter onboarding, self-service guidance, automation, and policy guardrails.
- Lead cross-team initiatives from design through fleet-wide rollout, mentor engineers, and maintain high standards for design, code review, and operational readiness.
- Troubleshoot workload and node lifecycle issues, including termination handling, pod disruption budgets, Karpenter timeouts, bin packing, and excess-capacity removal.
- Determine safe cluster operating limits and develop control-plane scaling patterns for bursty workloads.
- Analyze workload CPU, memory, disk, and network profiles to guide EC2 instance strategy and automate the analysis.
- Measure the effects of standards on availability, latency, risk, and cost to prioritize the roadmap.
- Participate in on-call for Kubernetes runtime issues and convert recurring failure patterns into systemic fixes.
- Collaborate with service, batch, ML workload, deployment, capacity, and SRE teams and keep current with Kubernetes best practices.
Requirements
- 5+ years of experience running Kubernetes in production at scale, ideally Amazon EKS across many clusters.
- Deep understanding of Kubernetes resource management and scheduling, including requests and limits, OOM behavior, CPU throttling, affinity and anti-affinity, taints and tolerations, and topology spread constraints.
- Strong knowledge of pod lifecycle and disruption management, including graceful termination, pod disruption budgets, and node draining.
- Experience enforcing configuration standards through admission control and policy-as-code, such as OPA Gatekeeper or Kyverno.
- Proficiency in Go or Python and experience building production infrastructure software such as Kubernetes controllers, operators, or admission webhooks.
- Strong production debugging skills and the ability to turn recurring incidents into systemic fixes.
- Experience leading technical initiatives across multiple teams, driving adoption of shared standards, and mentoring engineers.
- Experience quantifying infrastructure changes’ impact on availability, latency, and cost.
- Strong written communication skills for producing standards and guidance that teams can adopt independently.
Benefits
- Remote-first role open to candidates residing in specified Canadian provinces.
- All new hires are invited to an in-person onboarding experience, with occasional office work possible depending on the position.
- 100% subsidized medical coverage for employees and dependents, plus dental and vision coverage.
- Monthly technology, health, and wellness spending stipends.
- Flexible time off and generous holiday calendars.
- Employee stock purchase plan with a discounted opportunity to buy Affirm stock.
