At Affim, 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.

We are looking for a Staff Engineer to lead projects and initiatives on the Fraud Decisioning team.

• Effectively incorporate needs and opinions from stakeholders, advocate for ideas and initiatives, and create a common understanding where all voices are heard.
• Conduct technical and soft skill evaluations to inform and influence the hiring decisions. Develop and review the technical content and requirements of the interview process.

What We Look For

• 6-10+ years of experience as a software engineer with leadership responsibilities and experience mentoring junior engineers.
• Prior experience architecting, building, launching, coding and maintaining complex systems.
• Passion for working with cross-functional teams including Product, ML,Analytics and Business teams.
• A technical leader and team builder who can mentor the team in software development best practices.
• Expert at synthesizing complex business, product, and technical requirements to consistently produce high quality system designs and software.
• A system architect who can see the big picture and envision how business and product requirements can be broken up into system modules or components.
• This position requires either equivalent practical experience or a Bachelor’s degree in a related field.
