## About the role

As a senior engineer on the team, you will help set its roadmap, decide which standards matter most, and build a repeatable way to take each standard from research to enforcement across the fleet. Base pay is part of a total compensation package that may include equity rewards, monthly stipends for health, wellness and tech spending, and benefits (including 100% subsidized medical coverage, dental and vision for you and your dependents.) Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Define and evolve workload safety standards for Affirm's EKS fleet, such as CPU and memory settings, workload isolation and placement, tolerance for disruption, graceful termination to name a few
- Lead cross-team initiatives from design through fleet-wide rollout, mentor other engineers, and set a high bar for design, code review, and operational readiness
- Isolate workloads by criticality and resource profile so one misbehaving workload cannot degrade critical paths such as checkout
- Analyze workload resource profiles across the fleet (CPU, memory, disk, network) to guide EC2 instance type strategy, and automate that analysis as workloads change
- Measure each standard's impact on availability, latency, risk, and cost, and use the results to prioritize the roadmap
- Participate in on-call for Kubernetes runtime issues across the fleet, and turn recurring failure patterns into roadmap items
