About The Happiness Index

At The Happiness Index, we believe everybody has the right to be happy at work. People have a right to be human, not a number. To be listened to, not ignored. To be true to their values, and not to compromise.

We help companies provide these fundamental rights by providing them with technology that listens to their people. Our track record demonstrates it boosts company productivity, culture and financial performance. Our 20 people based in London inspire our customers who receive responses from 73 countries and 19 different languages to deliver on the right for people to be happy at work. We only employ people with the potential to positively transform our business and those around them as we have grand ambitions to revolutionise the way businesses interact with people.

The Role
We’re looking for somebody who is a natural problem solver, passionate about the work they do. Ideally, someone who knows PHP inside out and is familiar with both backend and frontend work. We’ve got some great aspirations for our platform so your role will be working with us to define and develop the future.
You’ll be responsible for helping to build a development team, reporting into our Head of Robots and looking after other developers, freelancers and working closely with our Growth and Brand Teams. You’ll be working with the team to help build and support all things tech, diagnose, troubleshoot and resolve problems if they arise. We’re keen to get the right person so are happy to discuss whether this means being a code wrangler, or someone who is involved with inspiring clients in pitches.
