Sr. Platform Software Engineer – AI and Innovation

We are seeking a Senior AI Software Engineer to join our growing team. In this role, you will architect and ship AI agents, agentic systems, and GenAI-powered tooling that transform how we develop software, serve customers, and scale operations. You'll own mission-critical distributed systems supporting payments and financial pipelines — and apply AI to make them smarter and more resilient. The ideal candidate combines deep software engineering experience (TypeScript, Node.js, PostgreSQL, GCP) with hands-on Generative AI implementation and brings excellent communication skills to translate business requirements into scalable, AI-driven solutions. Success in this role requires tight collaboration with product, design, and engineering leadership to identify high-impact AI opportunities and bring them from experiment to production. 

At First Dollar, we believe in empowering engineers to build a smarter health benefits platform - one where human expertise is amplified, not replaced, by AI tools. We seek engineers who have demonstrated experience using AI responsibly to accelerate their development workflow, improve code quality, and solve complex problems more efficiently. 

Our engineering team is built on the principles of humans over code. We are a tight-knit group of lifelong learners in a constant quest to be a team that is greater than the sum of its parts. Come join us!
