Founding Solutions Engineer – Denver

As the Founding Solutions Engineer
, you will be the technical linchpin connecting our fintech platform to our clients’ needs. In this early hire role, you’ll combine engineering know-how with customer-facing skills to ensure businesses smoothly implement our account-to-account payment API and tools. You will work directly with our customers’ development teams to integrate features like bank account linking, payment initiation, and identity verification into their products.

This is a unique opportunity to build the Solutions Engineering function from the ground up
, crafting best practices for future team members while having a direct impact on customer success and product adoption.

In a typical week, you might guide a client through integrating our RESTful API into their mobile app, assist in embedding our web-based bank connection widget, or troubleshoot implementation issues in a customer’s sandbox environment. You’ll act as both an educator and problem-solver—conducting technical workshops, creating sample code and demos, and advising on how to optimize use of our platform (for example, how to best leverage our real-time fraud detection or balance check features).

Internally, you’ll collaborate with product and engineering teams, relaying customer feedback and helping shape the product roadmap based on real-world use cases.

Thriving in this role requires a startup mentality
. You should be ready to tackle a wide range of technical challenges in a fast-paced, resource-constrained environment. As the first Solutions Engineer, you’ll also lay the groundwork for a growing team—documenting integration processes, building a knowledge base, and defining how we engage with clients technically. This full-time role is based in Denver, CO (with hybrid/remote work options) and offers a competitive base salary plus equity.

It’s ideal for someone who wants to have broad impact, influence product direction, and grow into a leadership position as the company scales.
