## About the role

As the Senior GTM Partner Systems Architect, you are the domain expert for our partnerships business systems. You own the Salesforce-to-partner-portal ecosystem, including all integrations with partner management and payment data.

## What they're looking for

- Stay hands-on: build proof-of-concepts and ship Apex, LWC, Flow, and complex integrations yourself. Track your work in GitHub to ensure it remains a reusable asset for the wider team
- Set and uphold engineering standards through architecture reviews, GitHub-based pull request reviews, and pairing that other developers build against
- Lead story and backlog refinement with the Product Owner, surfacing technical constraints and tradeoffs early, and looking around the corner to shape the roadmap before problems become urgent
- Mentor developers on system design, code quality, and tradeoff thinking, building the muscle for others to make good architectural calls without you in the room
