Job description

Software Engineer II - CIAM

Portland

Mid-Level

Engineering

At affirm, we’re using today’s technology to bring significant disruptive innovation to the financial industry. We focus on improving the lives of consumers by delivering simple, honest and transparent financial products.

We have roles across a variety of teams, including engineering, product, finance, operations, revenue, marketing, people and more.

A note to applicants: Fake job and recruiting scams are on the rise. affirm will never ask you to pay any upfront fees or send you any checks to purchase equipment during any part of the recruiting process. affirm only uses legitimate company email address domains (either “@affirm.com” or "@us.greenhouse-mail.io") to communicate with candidates via email.

Affirm is also proud to be a remote‑first company! Attracting great people starts by finding talent in different places. That's why we built remote work into the DNA of how we do business— but if an office space is more your style, we have offices in Chicago, New York City, Pittsburgh, San Francisco, Seattle, Toronto, Warsaw, Madrid and London.

Not to mention we have comprehensive and award-winning benefits that were made for you.

Job Description

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.

Affirm is building the next generation of customer identity and authentication. This role is a hands‑on, mid‑engineering position inside Information Security, contributing to core CIAM capabilities that protect customers and support growth.

You will help build and maintain backend services that power registration, login, authorization, and account lifecycle flows across B2C and B2B experiences. You will work with experienced engineers and partner teams to deliver scoped identity features with strong security fundamentals, reliability, and operational rigor.

What you’ll do

• Build and ship customer‑facing authentication features—from smoother login experiences to MFA, step‑up authentication, and device binding—with mentorship from experienced engineers.
• Develop backend services and APIs in Python or Kotlin, turning product requirements into working software that helps customers access their accounts securely.
• Work with modern identity technologies such as Okta, Auth0, and ForgeRock, writing custom code and integrations that connect identity capabilities to web, mobile, and partner applications.
• Take scoped features through the software development lifecycle: contribute to design, write readable code and automated tests, participate in code reviews, and deploy to production with support from the team.
• Solve real engineering problems by debugging services, improving reliability, and using logs and metrics to understand how your code behaves in production.
• Collaborate with engineering and product partners, learn secure development practices, and grow your software engineering skills while building expertise in authentication.

What we look for

• Demonstrated ability to write, test, and debug software in Python, Kotlin, or a similar language through coursework, internships, personal projects, open source, or professional work. No fixed minimum years of experience required.
• Foundational understanding of backend development, including APIs, data structures, databases, and version control.
• Genuine curiosity about how authentication works and motivation to build secure, reliable customer experiences. Prior experience with identity protocols or CIAM platforms is a plus, not a requirement.
• A practical problem‑solving approach, willingness to ask questions, and openness to learning through mentorship and code review.
• Clear communication and the ability to collaborate with engineering, product, and security teammates.
• This position requires either equivalent practical experience or a Bachelor’s degree in a related field.
