Who are Tyk, and what do we do? 

The Tyk API Management platform is helping to drive the connected world and power new products and services. We’re changing the way that organisations connect any number of their systems and services.

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.

  • Documentation: Create and contribute to policies and runbooks to ensure that operational processes are well-documented and consistently followed.
  • On-call Support: Provide on-call support, ensuring our Cloud services follow a 24/7 model by promptly responding to alerts, meeting SLAs, and automating root cause analysis.

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 – instill 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.
