Job description

Senior Staff Software Engineer, Backend (Identity Engineering)

Remote US

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 are looking for a Senior Staff Software Engineer to take on a key role in Identity Engineering to define the technical direction and foster innovation across the engineering organization. You’ll work closely with engineering leaders, cross-functional teams, and stakeholders to create solutions that are scalable, reliable, and high-performing. You'll help shape best practices, guide architectural choices, and drive the successful delivery of critical initiatives. This role requires a high level of technical ability, leadership skills, strong cross-functional communication, and a creative mindset.

Identity Engineering owns the systems responsible for onboarding all consumers and managing their authentication and verification journeys across Affirm’s product surfaces. In this role, you will need to gain a deep understanding of the business, product and engineering context, and utilize that context to define the requirements, vision, and roadmap of the Identity area. You will lead the team to influence and align with business stakeholders and engineering partners, and deliver the vision over multiple years in incremental milestones.

What You'll Do

• Define the multi-year, multi-team technical strategy and deliver it through direct implementation and broad technical leadership.
• Architect and build the next-generation Identity services, ensuring high availability and low latency to support Affirm’s financial products.
• Influence and align with cross-functional leaders across the organization, guided by deep domain context and engineering expertise.
• Mentor engineers and advocate for engineering excellence, influencing best practices across teams.
• Navigate ambiguity, bringing clarity to complex engineering, product, and business discussions.

What We Look For

• Proven experience delivering multi-year, high-impact projects with broad cross-functional collaboration.
• Strong system design and software engineering skills, with the ability to synthesize complex technical and business requirements.
• A strong understanding of distributed systems and how architectural decisions affect performance and maintainability.
• Excellent written and verbal communication, especially in asynchronous formats (RFCs, design docs, project plans).
• Passion for working with cross-functional teams including Product, Analytics, and Business teams.
• Kotlin development experience is a plus.
• Excited about Affirm’s mission to deliver honest financial products.
• This position requires either equivalent practical experience or a Bachelor’s degree in a related field.
