Senior Software Engineer - Fullstack

Hi, we're Brigit! A holistic financial health company helping everyday Americans build a brighter financial future. With a business model that is aligned with our customers, we create transparent, fair, and simple financial products that put money back in the hands of our members, help them spend wisely, avoid unfair fees and build their credit quickly. If autonomy, ownership, and having meaningful input at the company you work for is important to you, come join our growing team!

Brigit is doing innovative and exciting work, but don’t just take our word for it, our work is being recognized by others:

• Built In's 2026 Best Midsize Companies to Work For in New York City

• Built In's 2025 Best Places to Work For In New York City

• Built In’s 2024 & 2025 Best Startups to Work For In the U.S.

Brigit is looking for senior fullstack engineers to help us scale our next-generation consumer finance platform to millions of users in the next year. We’ve found tremendous traction helping low income Americans make ends meet; now is the time to scale. We’ve built a mobile/web app on React and React Native with Typescript, and a backend of Java services in Google Cloud. It’s served us well so far, but we need help making it even better.

1) Feature development supporting numerous external and internal applications. The next generation of our product may look nothing like it does today - and we welcome that! The degree to which we implement new user flows, compute our proprietary algorithms, integrate with 3rd party APIs, store data, and serve traffic will make or break our success.

2) Scalability of our customer-facing applications. Growing from 100k to 10 million users presents unique technical challenges. The efficiency and reliability of both our customer-facing and internal tools needs to improve. We have fun Data Engineering tasks, automation procedures, and availability/monitoring problems to tackle. We also have many user-facing projects, including the creation and upkeep of components and libraries, GraphQL API design, testing and QA processes, and CI/CD enhancements.

Our team is small and nimble; you'll be given an extraordinary amount of autonomy and ownership. More importantly, you have a large say in the direction of the company -- both in terms of our technology and our product.

• Building a Payments API platform that moves millions of dollars on a daily basis

• Implementing the advanced mathematical processes behind our proprietary risk algorithm

• Normalizing relational database schema to optimize for performance for over 1 million users

• End to end User notification (via SMS, Email, Push) capabilities

• Building internal tools that enable our Customer Support Specialists to help our customers ASAP

One of our greatest strengths is the speed at which we move. If you want to propose a new way of doing things, we are all ears. If you have an idea for a new feature, we'll be open to it. A new design paradigm? Bring it on.

At Brigit you can enjoy a mature CI/CD platform with automated deployment processes, an easy-to-use local/staging/production development environment, and teammates willing to fill in the gaps. We automate manual things so we can focus on thinking and building something that helps people.

As a fullstack engineer we’re looking for someone with experience owning a feature from start to finish on both the frontend and backend. We don’t expect everyone to know everything in our stack, but having one side of overlap (frontend/backend) that you feel very comfortable with will set you up for success here.
