Back End Developer

Posh AI
Boston, MA Full Time
POSTED ON 2/10/2025
AVAILABLE BEFORE 5/10/2025

Financial institutions - banks and credit unions - have begun a seismic shift in how they operate and serve their customers. History is being written right now. By joining Posh, you have an opportunity to help write the story.

Since 2018, we’ve been harnessing bleeding-edge technology to empower FIs to work smarter, and serve better. This isn’t hype - our products are powering millions of interactions every month for over a hundred unique financial institutions - and growing.

As AI & NLP advance at an unprecedented and aggressive pace, our promise is to stay two steps ahead. To both innovate ourselves - and embrace innovation from the collective industry - so that we bring the best solutions into production, now. We are building AI assistants for end-user customers and internal-user employees - all within a common ecosystem that share our most coveted moats - knowledge, aka what an assistant knows, and integration, what an assistant can do.

Many industry sectors each come with their own complexities - regulation, jargon, idiosyncrasies, etc.. Our customers want the best - and by definition, our vertical focus means that we can provide more nuanced and valuable solutions than horizontal ones that try to be everything for everyone. We believe verticalized AI will win, and the Financial Services sector is our sole focus.

If you’re eager to join a company that’s actively drafting the history books on the most seismic shift of FI strategy, we’d love to hear from you!
