Position Overview

GOVMINT serves collectors who place trust in every transaction. Behind that experience is an Adobe Commerce Cloud Pro (Magento) platform with established integrations across ERP, PIM, payments, and fraud. We seek a Senior Full Stack Engineer to collaboratively advance the platform's technical integrity and strategic development in partnership with our current engineering team.

This is a hands-on, code-forward role (approximately 70-80% development) working across the full Commerce stack: PHP back-end and module architecture, Magento-native front-end, integration design, and cloud operations. You will contribute to architectural decisions, collaborate closely with peers, and partner with Product, DevOps, and QA to deliver reliable, performant commerce experiences.

You are joining an active production platform with established integrations, first and third-party extensions, and ongoing modernization work. The strongest candidates for this role are pragmatic engineers who enjoy improving real systems, not just designing greenfield ones. You will have meaningful ownership and influence over the platform's direction.

This is a senior individual contributor role reporting to the Engineering Manager. You will work as a peer in the existing engineering team in a collaborative, low-hierarchy environment, with significant technical influence and the depth of work that comes from owning a complex platform end-to-end.
