Founded in 2015 with offices in London - UK, London - Ontario, Atlanta and Singapore, we have many thousands of users of our B2B platform across the globe. Brands using Tyk range from Lotte, Bell, T Mobile, to RBS, Capital One and Vinci. We have a varied user base hailing from every continent – even Antarctica.

Here’s why you should join us:

• Employee share scheme

We all share the same vision - we value authenticity, respect, responsibility, independence, honesty, diversity and inclusion and most importantly treating others how you wish to be treated. We look for like-minded people who bring their personalities to work everyday, strive to achieve their personal goals and who are willing to challenge the way we do things, why? - to make what we do even better!

Our values tell the story of Tyk - here’s how:

• It’s ok to screw up!

We’ve found that it’s often the ‘stupid’ or unexpected ideas that turn out to be the successful ones - so try it, at least we can say we have!

• The only stupid idea, is the untested one!

It’s in our DNA - starting a business with founders 12 hours apart, giving our gateway away for free - sure, we did that, and we’d do it again!

• Trust starts with you - make it count!

Trust is a two-way street - instil it from day one!

• Assume best intent!

We have each other’s back - we’re all on the same team. Think before you speak or act.

• Make things better!

Always try to leave things better than when you found them - change is constant, inevitable and embraced! Be that change we want to see.
