Full Stack Engineer

Cerbo•OptiMantra

Remote (US) · $100,000–$180,000 DOE

Cerbo•OptiMantra builds the EHR and practice management software behind functional, integrative, direct primary care, concierge, med spa, and behavioral health practices. Cerbo goes deep on clinical configuration and protocol-specific workflows. OptiMantra is built for practices that need to scale. Two platforms, one job: give practitioners technology that keeps pace with how they actually work.

This is a back-end heavy full-stack role in PHP and Laravel, deploying to the cloud (AWS, Azure, or GCP) with Git, Docker, and Kubernetes. You'll ship features alongside senior engineers and across product, design, and engineering.

The role asks for something specific: real fluency with AI coding assistants. The team wants engineers who read AI output critically, catch the subtle bug or security gap, recognize an outdated pattern, and know where a model is strong and where it hallucinates. They want engineers who use AI with judgment.

Builders use AI to take ideas all the way to shipped product. They move across the work of product managers, designers, and engineers. You build things on a weekend just to see if they work. You don't define yourself by the framework you use. You define yourself by what you put into production. If this sounds like you, this role is worth a look.
