Staff Full-Stack Software Engineer

About Treasury Prime

Treasury Prime builds APIs that give developers a direct connection to the banking system, making it easy to embed a full range of banking services, from bank accounts to custom debit cards, payments, and more, into their applications.

We're replacing the decades-old mainframe software that has hamstrung banks, making it difficult or impossible for fintech developers to build great products. Treasury Prime is the best way for banks to modernize their software stack and for fintech developers to find the best bank partner and get to market fast. Currently, we are using Clojure, React/Remix on the front end, Postgres database, and hosted on AWS & Vercel. We understand that many technologies are translatable; more importantly, we want passionate developers with a zest for knowledge and innovation!

Position Overview

We're looking for a Staff-Level Full Stack Software Engineer who can play a key technical leadership role in developing the UX our bank and fintech customers use daily. This is a frontend-heavy role (React-first), where you’ll help shape architecture, mentor engineers, and set technical direction for scalable, performant web applications. Your work will be the first thing new users see, and the essential tool bankers and developers rely on daily to know exactly what's happening with their money and customers.

You will:

• Lead the design, development, and maintenance of our web user interfaces, ensuring high performance and scalability 
• Shape and drive high-leverage frontend engineering projects, from technical vision and architecture guidance through execution
• Collaborate closely with product, design, and backend teams to launch features that directly impact our customers
• Mentor and coach other engineers, raising the bar for technical quality and helping them grow in their careers

You may be a good fit for this role if you:

• Have 10+ years of professional software engineering experience, with at least 2+ years operating at staff-level or above
• Deep expertise in React (and ideally modern frameworks such as Next.js or Remix)
• Have solid experience collaborating on UX and design to deliver highly usable products
• Set exceptionally high technical standards, ensuring performance, maintainability, and scalability in your code
• Have a passion for emerging technologies such as generative AI and blockchain
• Can communicate complex technical concepts clearly to engineers, designers, and non-technical stakeholders
• Thrive in a fast-paced start-up environment and are excited to create new things
• Bring broad backend exposure (SQL, APIs, distributed systems, Docker, databases) to complement your frontend expertise

While these are not hard requirements for the job, the best candidates will meet many of these criteria.

We look forward to hearing from you!
