Job Description

Position: Platform Engineer

Reports to: Cloud Platform Lead

Purpose

Harmoney runs a mature cloud platform on GCP that powers our consumer lending platform. We're now growing our Platform Engineering practice, and you'll be one of the people who shapes it. This is a broad, high-leverage role: you'll operate and evolve a substantial platform while laying the foundations that let the business innovate safely, especially as we adopt AI.

You'll work alongside our existing platform team engineers and the Cloud Platform Lead in a small, high-trust, SOC2-conscious team, owning meaningful problems end-to-end and helping define how the practice operates as it matures. [Platform Engineer JD | PDF]
