Senior Technical Lead – UK     At Horizontal Digital, we hold ourselves to one key belief: You’re only as good as your worst customer experience.

This means working across departments and engaging both our clients and our communities to deliver the greatest good.  Show hustle  We’re not ones to sit on our hands and wait.

This means understanding a variety of perspectives and holding ourselves to a higher standard of accountability.  Never settle   We motivate each other to push past the easy answers and collectively arrive at bigger, more inspiring ideas.       But enough about us. Let’s talk about you.      We are looking for an experienced Senior Tech Lead with deep expertise in Sitecore and a forward-thinking approach to AI-enabled delivery.
