Affirm Innovation & Technology Culture

Affirm’s technology culture is built around solving complex financial infrastructure problems with ownership, experimentation and a strong connection to customer impact. Engineers and technical teams are expected to build reliable products at scale, challenge ideas openly and use emerging tools thoughtfully to improve how work gets done.

• Mission-driven technical work: Affirm’s technology teams build products tied to its mission of delivering honest financial products that improve lives, including underwriting, payments, commerce infrastructure, machine learning and consumer experiences. The company reported about 23 million active consumers, 377,000 active merchants, more than 134 million FY’25 transactions and $36.7 billion in FY’25 gross merchandise volume, giving technical teams large-scale systems to support and improve.
• High standards for reliability and craft: Affirm’s technology culture emphasizes quality, ownership and accountability because its products move money and support consumer financial decisions. A senior vice president of engineering said employees “take pride in the craft of writing, testing and deploying high-quality software,” while Affirm’s security program includes encryption, application security, threat monitoring, PCI DSS Level 1 Service Provider status and SOC 1 and SOC 2 Type 2 reports.
• Experimentation and innovation: Affirm gives technical teams space to test ideas through hackathons, fast iteration and cross-functional problem-solving. Its hackathon program is designed to surface creative ideas that may influence the product roadmap, and the founder and CEO said, “Every year something becomes a thing that we hadn’t anticipated,” only to be elevated because it is “cool and interesting and makes a difference.”
• AI-enabled engineering culture: Affirm has also pushed its engineering organization toward agentic software development, with more than 800 engineers participating in a 2026 retooling week focused on using AI from ideation through implementation, testing and code review. The company reported that more than 60% of pull requests were agent-assisted during that effort and that “culture sets the ceiling,” including leadership conviction, psychological safety to experiment and clear accountability.
• External signals:
  • Technical challenge and talent: Employees on external review sites highlight Affirm’s smart colleagues, challenging technical work, cutting-edge technology, strong data infrastructure and access to AI resources as workplace strengths. Reviewers also describe the work as interesting and the teams as collaborative. (Glassdoor; Indeed)
  • Innovation and learning: External reviews point to learning opportunities, complex projects, strong engineering peers and a culture where employees can challenge themselves while working on meaningful products. (Glassdoor; Indeed; Comparably)
  • Employer recognition: Affirm’s technology and workplace reputation is supported by employer recognition, including Great Place to Work Certification, Fortune workplace recognition and recognition as a leading fintech company. 

Bottom line: Affirm’s technology culture combines mission-driven product work, high engineering standards, AI-enabled experimentation, collaborative problem-solving and large-scale technical challenges that give employees room to build, learn and innovate.
