Full-time | In-office with flexibility

Culture First

At MJM, we believe meaningful work starts with meaningful relationships. We serve ophthalmology practices, nonprofits, and purpose-driven organizations by helping them grow through strategy, creativity, and execution that matters.

We are looking for an experienced Web Developer who can confidently build, manage, troubleshoot, and improve websites while collaborating closely with our Creative, Account Services, and Strategy teams.

This role requires strong experience with WordPress development, front-end and backend troubleshooting, hosting and DNS management, and the ability to work cross-functionally with designers, strategists, and account managers to deliver excellent client outcomes.

This person should be proactive, detail-oriented, highly organized, and comfortable owning technical execution from start to finish.
