We are HF.  We are a pioneering global creative technology and content studio that has a proven track record of working with the biggest brands to develop groundbreaking solutions, while picking up a slew of awards along the way.  Clients and partners such Nike, Microsoft, TikTok, Vodafone and Saatchi work with us to develop bespoke, cross platforms solutions, both for their consumers and their internal teams & processes. 

We don’t see mixed reality as an emerging technology as we’ve been there from the start.  Exploring possibilities.  Crafting content.  Pushing the boundaries of what’s possible.  We straddle the line between dreams and reality, our technological process bridging that gap.

We’ve always stood on the precipice of the future and now it’s truly here.  We’re looking for the best to take these steps with us.  We need a Developer (Mid level) for our London operations in Old Street.  You will be joining a world-class team that strives to create the unimagined with every project.  It’s an exciting time for us with new offices in Milan and Verona, augmenting our London and Portland based operations.  We’re looking for truly ambitious, imaginative and world class talent to take this journey with us.


Harness our creativity, reputation and partnerships to continue to create world leading content while expanding our profile and global standing on the way.  We’ll go from leading the curve to owning the curve.


You are part of a team of passionate creatives, developers and producers who create world-class visualisation and immersive technology solutions that help transform customer experience, collaboration, and communication. 

You play a central part in building highly innovative commercial solutions for our B2B and B2C clients across a range of the most tactile and immersive mediums. 

You are a maker, someone that wants to get things done, you love to prototype with the most recent devices and software technologies on the market; looking for the latest betas to test, with the desire to push the boundaries of what is possible with technology. 


At HF, we thrive on problem solving, we are solution focussed, and we value freedom and responsibility as two sides of the same coin.
