About The Position

AACI Group, Inc. is dedicated to making insurance more accessible and affordable in catastrophe-prone regions. Climate change is increasing the frequency and severity of wildfires and other natural disasters, while carriers are retreating from high-risk markets. Homeowners are being left with fewer and more expensive options. We are addressing this challenge by building AI-native insurance agencies and digital services that combine risk data, loss prevention, and innovative product delivery. We are hiring a Senior Software Architect / Lead Engineer to set the technical direction for AACI Group's platform and ship the code that brings it to life. This is a hands-on, coding-first role, not a "meetings and diagrams" architect seat. You will design the systems across our business lines, and you will write production code alongside the team that builds them. You are the ideal candidate if you... Still write code daily and lead by doing Have worked across enough stacks to make sharp tradeoffs without belaboring them Treat AI tooling as a force multiplier in both how you work and what you build Take ownership of outcomes, not just architecture diagrams Move quickly without sacrificing reliability or maintainability We are building the ship as we are flying it, and we need a technical leader who can keep the platform stable today while compounding leverage for what we are building tomorrow.
