Software Engineer, Infrastructure

About the role

PYLON — THE AGENTIC SUPPORT PLATFORM PURPOSE-BUILT FOR B2B.

Pylon is the only agentic support platform, purpose-built for B2B companies. For leaders scaling AI-native support teams, Pylon lets humans and agents collaborate on customer work – investigating, resolving, and acting on every signal across every channel that matters.

Unlike platforms built before the AI era, Pylon enriches every interaction with deep account-level context, automates the low impact customer work, and surfaces answers before your team even has to ask. The result: faster responses, happier customers, and a system that continuously improves itself.

We're backed by a16z, BCV, General Catalyst, and Y Combinator. More than 1,500 companies including Linear, Cognition (makers of Devin), Modal Labs, and Incident.io http://Incident.io run their support and customer success workflows on Pylon. We're also featured on the Enterprise Tech 30 List https://www.enterprisetech30.com/.

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.
