At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most.

As a Manager of Sales Engineering, you’ll combine your People Come First leadership, technical depth, and communication skills to help enterprise merchant partners evaluate and integrate Affirm. You will lead and develop a team of Sales Engineers while actively participating in deals, guiding integration decisions, and building relationships with merchants’ technical and business leaders.

You’ll develop a deep working knowledge of Affirm’s products and integration solutions, participate in and lead technical sales calls, and provide hands-on support when the team needs coverage or additional technical leadership. You’ll also strengthen the team’s ability to build, test, and troubleshoot integrations in sandbox environments, grounding merchant recommendations in practical experience.

Sales Engineers are part of the Partner Engineering team and work closely with Affirm’s Revenue, Engineering, and Product teams. Together, you’ll solve merchant integration challenges, identify product enhancements, and build internal processes that scale.
