Collaborate cross-functionally: Partner with Product Owners, Business Analysts, Finance, CRM, Revenue Operations, and Support teams to translate business needs into technical solutions.
Drive continuous improvement: Proactively challenge the status quo to elevate code quality, modernize legacy codebase components, and explore new engineering tools and frameworks.
Maintain system health & observability: Debug and troubleshoot issues in production environments, managing relational database schemas (SQL) and Git/CI/CD workflows.
