Who we are

Founded in 2017, Creative CX is a specialist Experimentation Consultancy.

We help businesses to optimise, personalise and innovate across the entire customer experience, to drive measurable growth.

And we help them establish and scale experimentation programmes so that every team can experiment everywhere.

What is the job?

We’re lucky to work with fantastic clients such as the BBC, M&S, easyJet, AJ Bell, Hastings Direct, RSA, IHG, Primark, Premier Inn and YOOX Net-A-Porter Group.  Helping them to innovate and continuously improve through research and experimentation, and helping them to mature and scale their experimentation programmes.

However, Creative CX is growing because we’ve been winning additional clients and doing more great work for our existing clients. This is very exciting as it means it’s time to find a new talented individual to join our wonderful CCX team!

We’re looking for a Senior Technical Consultant with 5+ years of experience in Full Stack Development/Engineering with experience in building A/B testing & implementing experimentation services or Product Experimentation.

At Creative CX we believe that continually improving the customer experience through research, innovation and experimentation is critical for our clients to remain relevant and competitive. We strive to make a real difference to our clients’ businesses and their customers’ lives through the work that we do.

But to do this we need talented and smart people who can turn customer problems and insights from user behaviour into powerful ideas for optimisation and innovation.

As a Senior Full Stack Engineer specialising in experimentation, you will guide the implementation and build of client-side and server-side experiments.

• Deep understanding of experimentation methodologies and statistical principles.
• Proven experience in consulting or client-facing roles, with strong interpersonal and communication skills.
