Decagon - Senior Software Engineer, AI Developer Experience
Requirements
• 4+ years building production software, with meaningful experience in platform / devtools / infrastructure (or adjacent SRE/release engineering). • 4+ years • platform / devtools / infrastructure • Strong coding ability in at least one systems/productivity language (e.g., Python, TypeScript/JS), and comfort building developer-facing tooling (CLIs, libraries, automation). • Python, TypeScript/JS • Hands-on experience with CI/CD systems and designing pipelines that are scalable and reusable across many repos/services. • CI/CD systems • Practical experience with observability in production systems (instrumentation, alerting, dashboards, incident response). • observability • Comfort with containers and modern cloud infrastructure (e.g., Docker/Kubernetes and related tooling). • Docker/Kubernetes • A track record of improving developer experience through measurable outcomes (faster builds, fewer flakes, safer deploys, fewer incidents). • Strong cross-team collaboration and communication—especially writing clear docs and driving adoption. • Experience with monorepos and build systems and/or large-scale CI performance work. • monorepos • Experience building internal platforms: service templates, paved-road deployment, self-serve environments, developer portals. • internal platforms • Infrastructure-as-code experience (e.g., Terraform) and a security-minded approach to supply chain (provenance, secrets, least privilege). • Experience applying AI-assisted tooling to make engineers dramatically more effective.
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. • You might be a great fit if you • Have 4+ years of experience building production software, particularly in backend, infrastructure, platform, or developer tooling. • Are a strong programmer in Python, TypeScript, or another systems-oriented language. • Have designed and operated APIs, services, or platforms that other engineers depend on. • Understand distributed systems, cloud infrastructure, containers, and production reliability. • Have taken technically complex projects from ambiguous problem statements to widely adopted production systems. • Care deeply about developer experience and know how to turn complicated infrastructure into simple, useful abstractions. • Move quickly while maintaining a high bar for correctness, security, and operational quality. • Communicate clearly and enjoy working directly with the engineers who use what you build. • In addition to base salary, we offer competitive equity. Final compensation may vary based on location within the United States.
