About OnePay

OnePay is the consumer fintech trusted by millions of Americans to make money better.

Our financial system is broken. High fees, low rates, and too few ways to actually grow your money. We’re fixing it. And we’re moving fast.

We’re an all-in-one financial services platform that brings together banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto in one place. We also partner with employers, HCM providers, gig platforms, and others to deliver embedded financial services to millions of employees and frontline workers.

We’re backed by Walmart, the world’s largest retailer, and Ribbit Capital, one of fintech’s most respected investors, giving us rare scale, distribution, and the opportunity to build something truly category-defining.

But what really sets OnePay apart is how we move. Our customers don’t have time to wait… and neither do we. This place moves fast, and we’re looking for people who are:

• Ready to run

• Hungry and driven by urgency

• Exceptional at what they do, with low ego

• Comfortable operating in motion

The Role

As a Corporate Security Engineer at OnePay, you will lead the design, implementation, automation, and optimization of our corporate security infrastructure. You will enhance security controls, align goals with business objectives, and drive automation and self-service capabilities to maintain a strong security posture in a rapidly scaling environment.

• Work with IaC tools like Terraform to ensure enterprise configurations are steady, change-managed and machine-readable.

• Design and deploy endpoint security measures aligned with industry standards, including vulnerability management.

• Ensure a strong security posture for corporate SaaS applications by configuring vendor capabilities or building automations to meet OnePay standards.

• Mature and manage data protection controls, including Data Loss Prevention (DLP) tools and secure data handling processes.

• Build secure methods for sharing data with internal teams and external partners.

• Collaborate with IT, Infrastructure, and Security teams to implement security measures, maintain critical corporate systems (ensuring availability and compliance), and drive process improvement through automation.

• Develop and run incident response and disaster recovery plans, including tabletop exercises.

You bring

• 5+ years of IT experience, including 3+ years in enterprise security within cloud environments.

• Skilled at simplifying technical concepts for non-technical audiences and influencing decisions.

• Experience with workflow automation tools like n8n is a plus.
