- Code Quality and Release Discipline: Write production-grade code with appropriate test coverage. Follow established CI/CD standards, security practices, and release processes across every commit and deployment.
- Operational Ownership: Own the operational health of shipped features, including monitoring, incident response, and post-deployment fixes. Surface blockers, dependencies, and risk early in the daily product sync.

- 3+ years of experience in full-stack software development with production deployments
- Proficiency in modern frontend frameworks (React or equivalent) and backend API development
- Experience building and integrating with APIs, webhooks, and third-party platforms
- Solid understanding of CI/CD pipelines, version control (Git), and release management practices

WHAT SUCCESS LOOKS LIKE
- In your first 30 days — you are fully onboarded, environment is set up, you understand the Companion suite architecture, and you have shipped your first production contribution.
- In your first 90 days — you are operating independently against the roadmap, your code is consistently passing review and reaching production, and you have delivered at least one complete Companion module feature.
- By the end of your first year — you are a go-to engineer on the Companion suite, actively contributing to architecture decisions, and your work is measurably reducing manual operations across the business.
