Job Description:

Our client is looking for a Senior Full Stack Software Engineer with 4–12 years of experience to join a small, high-impact engineering team building AI-powered financial infrastructure for senior care. You'll take ownership of product initiatives end-to-end, breaking down ambiguity into shippable work and driving features into production independently. This AI-native fintech company processes $1B+ in payments annually, and this is a ground-floor opportunity to work directly with the CTO and shape both the product and engineering culture. Ideal candidates come from fintech or health tech backgrounds and thrive in fast-moving, early-stage environments where data integrity and speed both matter.

What will you be doing?

  • Own product initiatives end-to-end, scoping ambiguous problems, breaking them into deliverable chunks, and shipping to production
  • Make architectural and engineering design decisions that shape the platform's direction
  • Build full-stack features across React and Node.js powering payments, claims, and revenue automation for senior living operators
  • Collaborate cross-functionally with product and non-technical stakeholders to translate complex business processes into software
  • Leverage AI tooling and automation to build an AI-native product experience

Tech Stack: 

React, Node.js, JavaScript, TypeScript, PostgreSQL, Full-Stack Web Development, AI/ML
