About the role

Original posting from Pylon Labs via Ashby

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 1500 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.

WHAT YOU'LL DO

  • Design and maintain the core infrastructure across our cloud environments — own it end to end, not just keep the lights on.
  • Prevent incidents before they happen. Build the monitoring, alerting, and observability that catches problems while they're still small.
  • Make our systems scale. Find the limits before our growth does and engineer past them.
  • Own developer velocity. Build the CI/CD pipelines and internal tooling that let every engineer here ship faster.
  • Hunt down performance bottlenecks and speed them up.
  • Build for an AI-first workflow — lean on agents and automation to do more with a small team.

WHAT WE'RE LOOKING FOR

  • You have 3+ years in backend or infrastructure engineering and strong hands-on experience with cloud infrastructure.
  • You highly leverage AI for software development and can juggle multiple workstreams at the same time.
  • You’ve worked at startups previously and navigated ambiguous environments.
  • You genuinely enjoy building scalable and reliable systems
  • You have a growth mindset, want to constantly improve, and want to receive feedback.
  • 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
  • (Bonus) You have experience with our tech stack (React, Golang, GraphQL, and AWS).
  • (Bonus) You have experience with building agentic products in production.
