Software Engineer (AI Infra)

Pylon
San Francisco, CA

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 YCombinator, General Catalyst, and a16z. Pylon is a tool that thousands of users spend most of their day in.

Currently, 500+ companies including Linear, Cognition (makers of Devin), Modal Labs, and Incident.io use us everyday to run their support and customer success workflows. Also, we recently made this year's Enterprise Tech 30 List .

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.

Compensation and benefits

  • Medical, Vision, Dental insurance

  • 401K

  • Unlimited PTO

  • Food in the office

  • Fun team offsites and events - we're going to Hawaii this year!
