About the role

Senior software engineer role focused on building Decagon’s AI-native developer platform, spanning distributed systems, developer tooling, and applied AI to enable engineers and agents to plan, write, test, review, and ship production software.

Responsibilities

  • Design, build, and operate the core platform behind agent-driven software development at Decagon.
  • Lead ambitious platform projects from an ambiguous problem through technical design, implementation, rollout, and long-term evolution.
  • Turn successful experiments into secure, reusable abstractions that engineering teams can adopt without becoming experts in the underlying infrastructure.
  • Partner closely with engineers across the company to understand bottlenecks, prototype solutions, and drive adoption.
  • Improve the speed and quality of software development through better agent tooling, testing, review, and automation.
  • Own the reliability, observability, security, performance, and cost of the systems you build.
  • Help define how Decagon engineers—and increasingly autonomous agents—build and operate production software.

Qualifications

  • 4+ years of experience building production software, particularly in backend, infrastructure, platform, or developer tooling.
  • Strong programmer in Python, TypeScript, or another systems-oriented language.
  • Designed and operated APIs, services, or platforms that other engineers depend on.
  • Understanding of distributed systems, cloud infrastructure, containers, and production reliability.
  • Experience taking technically complex projects from ambiguous problem statements to widely adopted production systems.
  • Care deeply about developer experience and turning complicated infrastructure into simple abstractions.
  • Ability to move quickly while maintaining a high bar for correctness, security, and operational quality.
  • Clear communication and enjoyment of working directly with engineers who use the built tools.
