Software Engineer

MX is a fintech company on a mission to empower the world to be financially strong. We build technology that helps banks, credit unions, and fintechs deliver smarter, more intuitive financial experiences to millions of people.

Like many startups, we’ve navigated real growth challenges — and we’ve come out stronger on the other side. Today, MX is in a phase of renewed momentum and scale, with a solid foundation and a clear vision for what’s next. This is a place where thoughtful execution matters, innovation is encouraged, and individuals have real ownership over their work.

Our culture values curiosity, accountability, and impact. We give people the space to question assumptions, design better solutions, and help shape how the company grows. If you’re looking to do meaningful work, influence outcomes, and grow alongside a company that’s ready to move fast, you’ll feel at home at MX.

Our software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with their finances. Our products need to handle data at a massive scale. You'll work alongside the best and the brightest engineering talent in the industry. As a core participant of your team, you'll estimate engineering efforts, design your changes, implement and test your changes, push to live, and triage production issues. You need to be dynamic, collaborative, and curious as we build new experiences, improve existing products, and develop distributed systems powering the world to be financially strong.

This role is on the Experiences team, which builds MX's personal financial management (PFM) products: a money management dashboard, embeddable budgeting, spending, and cash flow widgets, and a personalized insights feed that financial institutions embed in their digital banking apps.

We're looking for a full-stack engineer, equally at home in React/TypeScript and the backend services behind it, who is well versed in applied AI. You'll ship LLM-powered features that make financial data easier to understand, safely and with sensitive data in mind, and help raise how the team uses AI tools to build and operate software.

We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.

With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions.
