We are seeking an Associate API Engineer to join a high-impact Payments Platform team supporting critical, customer-facing banking services such as Zelle, ACH, Wire Transfers, and High-Volume Transfer Systems. This team owns some of the most mission-critical infrastructure at the bank and is in the middle of a large-scale modernization effort, reimagining both the API layer and UI experience to build a best-in-class platform. This is a strong opportunity for early-career engineers to grow quickly while working on modern cloud-based systems at enterprise scale. You will be aligned to a specific product team (Zelle, ACH/Electronic Transfers, or Wire Transfers) and contribute to rebuilding and modernizing core banking rails using modern backend technologies.
What You’ll Be Working On
- Building, enhancing, and maintaining RESTful APIs supporting high-volume payment and transfer systems
- Contributing to a large platform modernization effort (Zelle & ACH)
- Developing new API services from the ground up and maintaining existing services
- Supporting both current platforms and next-generation modernized platforms
- Working within highly visible, customer-facing systems that are critical to daily banking operations
- Collaborating with engineers modernizing the service layer, including vendor-integrated solutions and cloud-native architectures
Tech Stack & Environment

- Strong fundamentals in Java and Spring Boot
- Comfort working in cloud-based environments (AWS or other major cloud platforms)
- Ability to clearly explain technical decisions, tradeoffs, and past work
- Interest in platform modernization, learning, and long-term growth
Note: Strong communication is important. We’re looking for engineers who can articulate what they’ve built and how they’ve contributed—depth matters more than raw years of experience.
