Do you want to help evolve a mature SaaS platform by building reliable, scalable back-end services in PHP? Do you enjoy working with frameworks, ORMs, automated testing, and pragmatic architecture that supports real customer-facing features?

Don’t look any further — Foleon is expanding the team and looking for a back-end developer who can strengthen our core platform while contributing to future-facing technology choices.

Foleon is a content experience platform for creating immersive, measurable digital publications. We’re growing our product and platform capabilities and need engineers who can build robust APIs, maintainable services, and well-tested back-end features that help our customers create better digital content.

Your Mission

As part of a cross-functional product team, you’ll design, build, test, and maintain back-end functionality across our platform. You’ll work primarily with PHP and Node-based systems, collaborate closely with front-end and product colleagues, and help modernize our architecture while keeping quality, reliability, and maintainability at the center of your work.

Design, build, and maintain back-end services, APIs, and platform features using PHP.
Work with relational data models, Doctrine, database migrations, and performance-conscious queries.

Analytical & Creative: You see the 'big picture' and can break down complex problems into manageable milestones.
Feedback Pro: You thrive in a culture of radical candor, where giving and receiving constructive feedback is seen as the ultimate tool for growth.

Hands-on experience designing and operating event-driven architectures using asynchronous messaging, pub/sub patterns, queues, and resilient integration flows.
Experience using AI-assisted development tools such as Claude Code, including effective prompting to improve productivity, code quality, and technical exploration.
