Job Description


The Role


As a Principal Engineer, you'll be leading the technical direction of a core pillar in our Engineering department: APIs.

You'll set the architectural vision, make high-impact technical decisions, and guide multiple squads towards building scalable, well-engineered software within our API ecosystem. This is a hands-on role, where you'll be designing, coding and solving the toughest technical challenges.

With a modern cloud-native stack and the freedom to approach problems with fresh thinking, you'll be working at the cutting edge, embedding AI, automation and best-in-class engineering practices into everything we build.

Our platform is primarily event-driven, so Kafka knowledge is critical, and we heavily leverage Salesforce as a key service, so enterprise knowledge of Salesforce or other CRMs is a big plus. Finally, our APIs are both synchronous and asynchronous, using both REST and GraphQL.
