About One

One’s mission is simple - to help customers achieve financial progress. We’re doing this by creating simple solutions to help our customers save, spend, borrow, and grow their money – all in one place.

The U.S. consumer today deserves better. Millions of Americans today can’t access credit, build savings or wealth, and are left to manage their financial lives through multiple disconnected apps. Almost a quarter of U.S. adults are unbanked or underbanked and roughly 80% of fintech users rely on multiple accounts to manage their finances.

What makes us unique? We are backed by a preeminent fintech investor (Ribbit) and the world’s largest retailer (Walmart), maintain the speed and independence of a startup, and employ a strong (and growing) collection of world-class talent.

There’s never been a better moment to build a business that helps people achieve financial progress. Come build with us!

• 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.

• Work closely with IT, Infrastructure, DevOps, and other Security teams to implement and refine technical security measures.

• Own and maintain critical corporate systems, ensuring reliability and smooth updates.

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

• Identify and implement automation solutions to simplify and improve security processes.

You bring

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

• Expertise in AWS IAM, managing roles, policies, and integrating third-party SaaS applications.

• Strong experience with macOS management tools (e.g., Jamf Pro), MDM solutions, and securing SaaS platforms like Google Workspace and Okta.

• Solid understanding of networking, authentication standards, and frameworks like MITRE ATT&CK, NIST CSF, and CIS benchmarks.

• Advanced skills with Infrastructure-as-Code tools like Terraform to configure and secure infrastructure and platforms.

• Skilled in scripting with Python and/or TypeScript.

• Hands-on experience with Zero Trust Network Access (ZTNA) and Data Loss Prevention (DLP) solutions like Netskope or Zscaler.

• Proven ability to lead large projects, automate processes, and achieve measurable security improvements.

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

Leveling Philosophy

In order to thoughtfully scale the company and avoid downstream inequities, we’ve adopted a flat titling structure at One. Though we may occasionally post a role externally with a prefix such as “Senior” to reflect the external level of the position, we do not use prefixes in titles like that internally unless in a position which manages a team. Internal titles typically include your specific functional responsibility, such as engineering, product management or sales, and often include additional descriptors to ensure clarity of role and placement within our organization (i.e. “Engineer, Platform”, “Sales, Business Development” or “Manager, Talent”). Employees are paid commensurate with their experience and the internal level within One.

Inclusion & Belonging

To build technology and products that are used and loved by people and solve real-world problems, we need to build a team with many different perspectives and experiences. We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. We encourage candidates from all backgrounds to apply. Applicants in need of special assistance or accommodation during the interview process or in accessing our website may contact us at talent@one.app.
