About the role
- Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest.
- We're the team that tells the business what it's spending, why it's changing, and what to do about it - from AWS resource waste and tagging strategy to the newer frontier of AI/LLM spend across the company's growing set of AI tools.
- We're a small, high-leverage team - you'll have outsized influence on how Affirm thinks about cost.
Responsibilities
- You will collaborate across teams in the product development lifecycle by collaborating with product management, design & analytics to ensure technical sustainability, risks and trade-offs are well understood and managed.
- You will foster a culture of quality and ownership on your team by setting code review and design standards for your team, and advocating for them beyond your team through your writing and tech talks.
- You will help develop talent on your team by providing feedback and guidance, and leading by example.
- Track record of building automation or tooling (Python, Terraform, or similar) that turns a manual cost-review process into a scalable, self-service system - not just one-off analysis.
Requirements
- You have 8+ years of experience designing, developing and launching backend systems at scale using languages like Python or Kotlin.
- Experience with a FinOps or cost-visibility platform (e.g., FinOut, CloudHealth, Kubecost, or an internal equivalent) - building dashboards, anomaly detection, or savings/waste reporting rather than just consuming them.
- You have experience delivering major features, system components or deprecating existing functionality in a system through the definition of a technical and execution plan.
- Your growth and impact trajectory demonstrates that you have mastered gathering and iterating on feedback from your engineering and cross-functional peers.
Skills
- We treat cost anomalies with the same rigor as production incidents:
Compensation
