What You’ll Do:

  • Set the technical vision and strategy for the next generation of traffic management, capacity planning, and load testing capabilities and practices at Affirm.
  • Safely build and expand our traffic management capabilities by applying a deep understanding of traffic management: gentle retries, circuit breakers, load shedding, and load prioritization.
  • Collaborate with the broader engineering organization to understand service load: from day to day operations to peak events. Then develop and rollout next generation capacity models and load testing frameworks.
  • Champion innovative, scalable, and delightful solutions across the engineering organization
  • Promote a strong culture of innovation, drive evaluation, development and roll out of new technologies/frameworks. Actively research, brainstorm, prototype, and present ideas.


This role requires an engineer who can work at multiple levels: effectively convey a clear vision, influence senior leadership to focus on strategic investments, and lead fellow engineers to achieve impactful results.


What We Look For:

  • Has been responsible for traffic management, load testing or capacity planning at an organization with hundreds of millions of users.
  • Extensive experience in designing and implementing traffic shaping, cluster management, and load shedding systems at scale
  • Successful track record leading and delivering multi-year, highly complex engineering infrastructure projects.
  • Demonstrated ability to successfully develop and partner with staff and senior staff software engineers.
  • Exceptional leader who can mentor high potential engineers earlier in their career. 
  • Detail oriented individual who has strong opinions on the technologies being developed by their team and is fully immersed in day to day execution and delivery.
  • Strong communicator who effectively lays out their technical vision to the broader engineering organization.
  • 15+ years software engineering experience.
  • This position requires either equivalent practical experience or a Bachelor’s degree in a related field
  • Experience with Fintech and Retail industries for both B2C and B2B (merchants/affiliates) is a plus.
  • Excited about both our mission to deliver honest financial products and to do it by building a meritocracy.
