Software Engineer

About Luthor

Luthor builds AI-powered governance for enterprise communications.

We help financial and legal institutions review, approve, and monitor marketing and communications workflows at the speed of modern content production.

Over the past year, we’ve onboarded some of the world’s largest financial institutions, surpassed $850B+ AUM on platform, and expanded across banks, lenders, asset managers, and law firms.

We’re now hiring a Staff / Senior Software Engineer to help build the core systems powering the platform across applied AI, workflow orchestration, retrieval, policy enforcement, auditability, and multimodal review.

You’ll work directly with the founding team in San Francisco and deploy AI systems into real production environments where accuracy, reliability, and trust actually matter.

About the Role

As our second full-time engineering hire, you’ll work directly with the CEO and CTO (both engineers) to design and build the backbone of our platform.

You'll interface directly with our customers and prospects to gather feedback to develop novel solutions to the unique problems they face around marketing compliance.

This is startup life in its truest form: fast-paced, challenging, and immensely rewarding. You’ll take ownership of your work, see the immediate impact on customers, and help define the engineering culture for years to come.
