Ally and Your Career

Ally Financial only succeeds when its people do - and that’s more than some cliché people put on job postings. We live this stuff! We see our people as, well, people - with interests, families, friends, dreams, and causes that are all important to them. Our focus is on the health and safety of our teammates as well as work‑life balance and diversity and inclusion.

From generous benefits to a variety of employee resource groups, we strive to build paths that encourage employees to stretch themselves professionally. We want to help you grow, develop, and learn new things. You’re constantly evolving, so shouldn’t your opportunities be, too?

Ally designates roles as (1) fully on‑site, (2) hybrid, or (3) fully remote. Hybrid roles are generally expected to be in the office a certain number of days per week as indicated by your manager. Your hiring manager will discuss this role’s specific work requirements with you during the hiring process. All work requirements are subject to change at any time based on leader discretion and/or business need.

At Ally, you get a startup feel, but experience the benefits of a company that has worked out the kinks and is fulfilling its purpose. We are always evolving and see that as a good thing. From owning our work to seeing its impact in the real world, our team is relentless in finding new ways technology can help make experiences better and help people.

Join Ally’s Identity Shield and Consumer Fraud team to build authentication and identity infrastructure that protects our digital banking customers and enables intelligent fraud prevention. You’ll develop systems that implement fine‑grained access control, manage authentication and authorization flows across Ally’s digital banking ecosystem, and generate the behavioral and contextual signals that power adaptive fraud detection.

At this time, Ally will not sponsor a new applicant for employment authorization for this position.

As a backend engineer on this team, you’ll tackle fascinating challenges implementing identity protocols at scale—building OAuth 2.0 and OpenID Connect flows, developing authorization engines that evaluate complex policies with millisecond latency, and serving authentication decisions that directly impact our ability to keep customers safe and prevent fraud. You’ll work with modern cloud technologies to build resilient, scalable platforms where performance and reliability are non‑negotiable.

This is your opportunity to shape Ally’s next‑generation identity and authentication infrastructure, mastering security‑first design principles, distributed systems, serverless architectures, and AI‑assisted development workflows.

This role offers the rare combination of high‑impact work, cutting‑edge technology, and meaningful outcomes. You’ll collaborate across engineering, product, security, and data science teams to solve complex problems that matter. Whether you’re developing authentication services that adapt to risk signals, implementing passwordless flows using passkeys and biometrics, building integrations with enterprise identity providers, or designing event streams that carry authentication signals to fraud detection systems, your work will be visible and valued.

On this team, we believe in relentless progress balanced with sustainable pace. We support each other, celebrate wins, learn from setbacks, and foster an environment where everyone can do their best work. Our #1 goal is team success, and our people are above all else.
