AT PYLON, WE'RE BUILDING THE FUTURE OF B2B POST SALES.

We’re building the all-in-one B2B post-sales support platform powered by conversational data and layered with intelligence to help our customers run their operations in real-time.

We’re backed by a16z, BCV, General Catalyst, Y Combinator.

Currently more than 1300 companies including Linear, Cognition (makers of Devin), Modal Labs, and Incident.io http://Incident.io run their support and customer success workflows with Pylon. You'll also find us on the Enterprise Tech 30 List https://www.enterprisetech30.com/.

Our product has a very large problem space so there’s a ton of stuff to build and take ownership of - we’d be excited to get your help as we're hiring several extremely talented software engineers across the stack.

IN THIS ROLE, YOU WILL...

  • Build the platforms that power Pylon's AI features - prompt executions, search infra, and more!
  • Improve LLM observability - AI evals (online and offline), scorers, and set up Pylon's AI for the next wave of scaling
  • Improve the quality and performance of AI features

YOU MIGHT BE A FIT IF THE BELOW DESCRIBES YOU...

  • You dislike meetings and would much rather focus your time on building, being productive, and shipping code
  • You have strong engineering fundamentals, code efficiently, and you know what you're great at and what you're less great at
  • You thrive when you have autonomy, own as many of the details as possible, and project manage your own work
  • You're in SF or you're willing to relocate, you love working in-person, and you're serious about joining us to build a culture we'll all love
  • We work with React, Golang, GraphQL, and AWS
  • You'll join a strong technical team of senior engineers from places like Samsara, Affinity, and Airbnb.
