Senior Software Engineer - IAM

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 building the next generation of Identity and Access Management at Affirm. This is a software engineering role focused on evolving and extending our enterprise identity platform.

SailPoint & Auth0 are core systems in our environment. You will work directly within it, but your responsibility goes beyond configuration. You will design and build automation, integrations, and intelligent workflows that reduce manual operations and move us toward a highly scalable, AI-assisted identity platform.

If you are excited about combining backend engineering, cloud-native systems, CI/CD discipline, and AI-driven automation within the identity domain, this role is for you.

What You’ll Do

Own and evolve our SailPoint & Auth0 based identity platforms, including workflows, integrations, and governance controls

Design and build backend services and automation frameworks that extend SailPoint & Auth0 capabilities

Develop AI-assisted workflows that interpret structured and unstructured inputs such as Jira tickets and generate safe, reviewable IAM changes

Build human-in-the-loop automation systems for provisioning, role modeling, and privileged access management

Design, implement, and maintain CI/CD pipelines using GitHub and Buildkite to ensure safe, reliable deployments

Improve test coverage, code quality, and release automation across the Identity platform

Integrate with AWS services and other enterprise systems using secure, scalable APIs

Use modern AI development tooling such as cloud-based AI services, Cursor, and model context protocols to accelerate secure automation development

Partner with Security, IT, and Engineering to define the long-term architecture of identity at Affirm

Example problems you may work on:

Building a platform that reads Jira tickets, uses AI to determine required IAM changes, proposes those changes for human approval, and safely executes them in production

Designing event-driven identity lifecycle automation across HR, access governance, and privileged systems

Creating reusable frameworks for secure, AI-powered access management workflows

Establishing automated testing and deployment standards for identity infrastructure

What We’re Looking For

Must have

5+ years of professional backend software engineering experience

Strong production experience in Python or a similar backend language

Experience designing APIs, automation frameworks, and distributed systems

Hands-on experience building and maintaining CI/CD pipelines

Ability to pass a backend software engineering interview and contribute production-quality code regularly

Nice to have

Experience with cloud-native development, preferably AWS

Experience working with IAM or IGA platforms such as SailPoint, or CIAM Platforms such as Auth0

Familiarity with tools such as Cursor and other AI-augmented development environments

Experience with infrastructure as code such as Terraform

Familiarity with compliance frameworks such as SOC 2, SOX, ISO, or PCI
