  • • Join OneApp Technologies Inc., a rapidly growing consumer fintech company backed by Walmart and Ribbit Capital, as a Software Engineer on our critical Risk team. We are on a mission to revolutionize the financial system by making money better for millions of Americans. Our all-in-one financial services platform integrates banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto, while also partnering with employers and gig platforms to embed financial services for frontline workers. We operate at an unprecedented pace, and we are seeking highly driven, exceptional individuals who are ready to run and operate comfortably in motion.
  • • As a Software Engineer on the Risk team, you will play a pivotal role in safeguarding our customers and the company by developing and maintaining the robust backend systems that underpin our fraud detection, identity verification, and transaction monitoring capabilities. Your work will directly contribute to the integrity and security of our financial platform, ensuring a trustworthy experience for our millions of users.
  • • You will be responsible for building resilient, scalable, and high-performance backend services and APIs. These services are the backbone of our real-time risk and fraud prevention mechanisms, requiring meticulous development, rigorous testing, and ongoing maintenance to ensure their reliability and effectiveness.
  • • Collaboration is key to our success. You will partner closely with product managers, fellow engineers, and other stakeholders to design, implement, and deploy sophisticated systems. These systems are designed to protect customer accounts and transactions from fraudulent activities, requiring a deep understanding of potential threats and robust mitigation strategies.
  • • A significant aspect of your role will involve integrating with various third-party risk and compliance platforms. This requires ensuring seamless, secure, and efficient data flows between our internal systems and external partners, adhering to strict security protocols and regulatory requirements.
  • • You will have a direct impact on architectural decisions, contributing to the design of systems that must balance the critical needs of scale, security, and reliability. This is particularly important given the sensitive nature of the financial data and transactions we handle.
  • • We value transparency and operational excellence. Therefore, you will be expected to build and maintain clear, comprehensive documentation for the systems you develop. This documentation will support effective collaboration among team members, facilitate knowledge sharing, and ensure smooth operational handoffs.
  • • The Risk team operates at the forefront of fintech security, tackling complex challenges in a fast-paced environment. You will be instrumental in developing innovative solutions that not only prevent current threats but also anticipate future risks, ensuring OnePay remains a leader in financial security.
  • • This role offers a unique opportunity to work with cutting-edge technologies and contribute to a product that is fundamentally changing how people manage their finances. You will be part of a team that is passionate about building secure, reliable, and user-friendly financial products.
  • • We encourage a proactive and builder-oriented mindset. You will have the autonomy to identify areas for improvement, propose solutions, and drive their implementation, making a tangible impact on our platform's security posture and our users' trust.
  • • Your contributions will be essential in maintaining the trust and confidence of our millions of users, ensuring that OnePay continues to be the go-to platform for secure and accessible financial services.
  • • We are building a category-defining company, and the Risk team is at the heart of ensuring its stability and trustworthiness. This is a chance to be part of something truly significant in the fintech landscape.
  • • You will be working within a modern microservice-oriented architecture, leveraging technologies like Node.js, TypeScript, NestJS, Kubernetes, and AWS. While specific experience with our exact stack is not mandatory, a strong foundation in modern software engineering practices will enable you to quickly become productive.
  • • The role demands a proactive approach to problem-solving, a commitment to writing clean and maintainable code, and a dedication to delivering high-quality software that meets stringent security and performance standards.
  • • You will be an integral part of a high-growth, mission-driven, and inclusive culture where your work has real impact and is recognized. This is an opportunity to grow your career alongside a company that is making a significant difference in the financial lives of Americans.
