Lead Software Engineer

Alternative Payments is building the financial operating system for SMBs, consolidating the disconnected tech stack that holds service-based businesses back. Starting with MSPs, we’ve spent five years perfecting accounts receivable, and we’re now expanding into accounts payable, AI-powered analytics, and beyond. We’re at an inflection point: closing the loop on money movement and laying the foundation for a platform that will reshape how service businesses operate financially.

We’re growing fast, thinking big, and building a global team that wants to be part of something that lasts. We believe the best solutions come from diverse perspectives, deep collaboration, and a shared obsession with customer impact. If you’re energized by real problems, real customers, and real impact, we want to hear from you!

What We’re Looking For

We’re looking for a Lead Software Engineer to help set the technical direction of Alti, our AI agent product. Alti launched in July 2026 and has moved past MVP. The next step is scaling it into a core product of our platform: more agents, more automated routines, and our own machine learning models alongside LLMs.

You’re a product engineer who has built AI features in production and can raise the bar for the whole squad. You’ll own technical decisions across Alti,
