DESCRIPTION
As a Principal Engineer / Domain Architect in the Engage domain, you will help evolve multiple successful teams into a cohesive, scalable platform that powers customer conversations. This is a hands-on individual contributor role where your impact comes from working closely with engineers, contributing to code, and enabling better technical decisions across teams.
You will operate across Inbox, Contacts, Mobile, and Conversation Starters, shaping architecture, reducing friction,
and raising engineering maturity, not through top-down ownership, but through influence, clarity, and practical solutions.
Key responsibilities include:
- Enable teams by providing practical patterns, guardrails, and decision frameworks that are adopted because they are effective
- Contribute directly to production code (Java and TypeScript) and prototype solutions to validate architectural decisions
- Define and maintain a clear architecture direction (current state, target state, and evolution path) for the Engage domain
- Drive operational excellence, including observability standards, reliability practices, and infrastructure discipline (e.g. Terraform-first approach)
- Define frontend architecture standards, including micro-frontend boundaries, contracts, and independent deployment models
- Coach engineers and teams to build architectural thinking and decision-making capability
