Full Job Description
About the Team

The Infrastructure team builds and operates the foundations that power Decagon: networking, data, ML serving, developer platform, and real-time voice. We partner closely with product, data, and ML to deliver high-scale, low-latency systems with clear SLOs and great developer ergonomics.

About the Role

We're looking for a Senior Software Engineer to help build and evolve our internal developer platform-everything from CI/CD and release automation to observability standards, platform tooling, and developer workflows that remove friction.

This role is for someone who loves making other engineers faster: reducing build times, eliminating flaky tests, creating paved roads for service creation/deployment, and raising the bar on operability by default. Roles like this often combine "builder" energy with strong empathy for how engineers actually work.

What you'll do
  • Developer productivity & platform tooling
    • Identify workflow bottlenecks (build/test/release/local dev) and build tools that measurably reduce toil.
    • Create and maintain "golden paths" like service templates, CLIs, libraries, and automation that teams rely on.
  • CI/CD & release engineering
    • Design reusable CI pipelines and deployment workflows that are fast, safe, and easy to adopt across teams.
    • Improve reliability of builds and tests (flake reduction, hermeticity, caching) and drive down cycle time.
    • Support progressive delivery patterns (canary / blue-green) and safe rollback mechanisms.
  • Observability & operational excellence
    • Establish shared observability primitives (metrics/logs/traces), standards, and libraries so services are production-ready by default.
    • Partner with product engineers to improve operability: SLOs, alerting hygiene, dashboards, incident learnings.
  • Infrastructure foundations
    • Build and improve core platform capabilities that make it easy to run and scale services.
  • Ownership & reliability
    • Own the systems you build end-to-end and help keep them healthy in production, improving reliability over time.


Your background looks something like this
  • 4+ years building production software, with meaningful experience in platform / devtools / infrastructure (or adjacent SRE/release engineering).
  • Strong coding ability in at least one systems/productivity language (e.g., Python, TypeScript/JS), and comfort building developer-facing tooling (CLIs, libraries, automation).
  • Hands-on experience with CI/CD systems and designing pipelines that are scalable and reusable across many repos/services.
  • Practical experience with observability in production systems (instrumentation, alerting, dashboards, incident response).
  • Comfort with containers and modern cloud infrastructure (e.g., Docker/Kubernetes and related tooling).
  • 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.


Even better if you have
  • Experience with monorepos and build systems and/or large-scale CI performance work.
  • Experience building internal platforms: service templates, paved-road deployment, self-serve environments, developer portals.
  • 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.

  • Medical, Dental, and Vision benefits for you and your family
  • Life Insurance and Disability Benefits
  • Retirement Plan (e.g., 401K, pension)
  • Parental Leave
  • Fertility and family building benefits through Carrot
  • Daily lunches and snacks in the office to keep you at your best
