About the Role

The Sr. Software Engineer is a critical role responsible for designing solutions and delivering complex features across our product platforms. You will leverage AI tools and co-worker agents such as Claude Code to specify, implement, validate, deploy, and support features end-to-end, focusing your expertise on architectural judgment, code quality, and mentorship.

As a senior member of a domain-aligned cohort, this position contributes deep expertise to the cohort’s product domain and interfaces with the Engineering Manager, Product Manager, and fellow cohort members to deliver scalable SaaS products with high velocity. You’ll drive the evolution of AI-assisted development practices, mentor engineers within the cohort on effective AI tool usage, and share knowledge across cohorts.
