Position Summary & Responsibilities

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 run their support and customer success workflows on Pylon. We're also featured on the Enterprise Tech 30 List.

What you'll do

Own application and product security across what we've shipped and what's still to come, including threat modeling, secure design reviews, and code review on the areas that matter most like auth and access control.
Build tooling that scales security past one person: supply chain security, vulnerability management, secure-by-default libraries, and developer-friendly guardrails.
Run the vulnerability lifecycle end to end (triage, validation, prioritization, remediation) and help mature our bug bounty and disclosure programs.
Build AI-assisted security workflows, like agents that scan code, propose fixes, and surface real risk, along with the controls that let the rest of the team use coding agents safely.
Work hands-on with engineers to ship fixes and help them build securely by default, telling the difference between theoretical risk and risk that actually matters so we spend effort where it counts.
Take projects from customer request through design to ship, and own them the whole way through.
