WFH Flexible Alexandria, VA

Mid-Level Developer

NJI is a wildly creative and strategically disciplined agency with offices in London, Washington, D.C., and Singapore. We work seamlessly across teams and time zones to align and deliver for our clients.

We seek an experienced and versatile web developer to join our office with at least 2+ years of experience who enjoys a broad range of both front-end and back-end development responsibilities. The ideal candidate is able to quickly, independently, and precisely build a custom WordPress website from design assets and functional documentation. Maintenance and updates to existing sites also factor heavily into the responsibilities of this position. PHP and Wordpress experience is a must – we frequently build on proven and popular content management systems like Drupal and Wordpress. 

We hope to find a developer that can build a site from Sketch/Figma into a custom WordPress theme.


Please examine the many skills we look for in a candidate. The right technical experience and skill will get you an interview, attitude and professionalism will get you the job.

  • Gulp/Grunt, Bower package manager.

Work Hard Where You Are.

Part of our secret sauce is facilitating great collaboration across our creative teams. From farmers to urban foragers, trapeze artists to Mario Kart fanatics, we have colleagues with diverse interests, and we’re at our best when we bring these perspectives together. This position will only be considered for someone local to the London office who can come join in our collaborative efforts. That being said, NJI maintains a hybrid/remote work policy for all offices and the team here regularly splits their time between the office and working from home. We are unable to offer work visa sponsorship at this time. 

Cover Letter.

We think of cover letters more in the old-fashioned pen pal sense. So, keep the job summary and skills list in your resume, and write something that personally expresses who you are and what draws you to NJI and this role. 

Diversity Commitment.

Authenticity is the foundation of boundless creativity. Rooted in diverse life experience, our team challenges the status quo through our work and culture every day. We are committed to sustaining and improving NJI's inclusive workplace by actively expanding the diversity of our team. We encourage people from underrepresented groups to apply.
