About the role

Pylon is an agentic support platform for B2B companies. This role focuses on building and maintaining scalable, reliable infrastructure, with emphasis on AI-first workflows, monitoring, CI/CD tooling, and performance optimization.

Responsibilities

  • 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.

Qualifications

  • 3+ years in backend or infrastructure engineering and strong hands-on experience with cloud infrastructure.
  • Highly leverage AI for software development and can juggle multiple workstreams at the same time.
  • Experience at startups and navigating ambiguous environments.
  • Genuine interest in building scalable and reliable systems.
  • Growth mindset, openness to feedback, and desire to continuously improve.
