[Hiring] Senior Full-Stack Software Engineer @Paytient

Role Description

We're actively recruiting for a Senior Full-Stack Engineer who is motivated by solving big challenges and passionate about working closely with product managers, designers, and other engineers to build elegant software. If you're excited about working at a high-growth, venture-backed company and want to make an impact by building products that help people, we'd love to hear from you!

In this role, you'll work primarily on the backend while contributing across the full stack, including frontend (React/React Native) and backend (Java/Spring Boot + Kotlin) applications. Deep backend expertise is essential, while frontend experience is a plus - we'll look to you to own complex server-side systems and collaborate on frontend as needed. This position is on our Growth & Core Ops Product Engineering team, where we build the foundational systems that power our business. As an Engineer on this team, you'll solve complex, high-stakes backend challenges, from automating intricate payroll deductions and ensuring the integrity of member census data, to transforming manual processes into elegant, automated workflows for invoicing, subscription management, and financial reporting.

Our "remote with roots" model allows us to work where we thrive and gather as needed, often in our home office in Columbia, Missouri. This role can be performed from anywhere in the continental U.S., with the exception of Montana.

• Experience with or interest in React for occasional fullstack contributions is a plus.
• An AI-forward mindset, with experience using AI assisted development tools (like GitHub Copilot, Claude Code, or OpenCode).
• Comfort working in a cross-functional environment, collaborating closely with Product, Design, Compliance, Support, and Operations.
• A history of building features for complex, high-scale backend systems, with exposure to user-facing web or mobile applications.
• Strong communication skills and the ability to work effectively in a remote or hybrid setting.
• Preferred: Experience in Fintech, Healthcare, HRIS, or Benefits Administration (specifically dealing with payroll, census data, or tax logic).
• Bonus: Experience working in regulated industries within security and compliance frameworks like SOC 2 and HITRUST.

Requirements

• Collaborate with product managers, designers, and engineers to build scalable, reliable backend systems.
