Cookpad is a tech company building a community platform that enables people to share recipe ideas and cooking tips. It’s a global platform used by on average around 100 million people every month across the world. Over 4 million recipes have been created by people in more than 70 countries. How we got started.

Our mission is to make everyday cooking fun. We believe we can build a better world through encouraging even more people to cook. Everyday, home cooking has a profound impact on ourselves and the world around us: it makes us healthier and connects us with our friends and family. Through solving the problems related to everyday cooking, we help people live happier and healthier lives in an environment that is more sustainable. That’s how we want to impact the world.

Cookpad is one of Japan's best known tech companies, listed on the Tokyo Stock Exchange, and was already highly successful before launching globally in 2013. With strong backing we have spent the last few years building the global platform and we are now in our commercialisation phase of the business.

Our goal is to be the number one recipe sharing platform in 100 countries by 2021. It’s an ambitious target which means we need to constantly adapt and enhance our service in response to feedback from our users.

Why join Cookpad?

People join Cookpad to be part of something bigger - to make a difference.

We offer competitive salaries and all the benefits you’d expect, including a generous 7% employer pension contribution, private medical insurance + cycle to work,, and workplace nursery schemes.

We started working from home in the very early stage of the pandemic to keep our members safe. Along with relaxed restrictions, our office is operated with limited capacity at the moment but expecting to recover. Before the pandemic, we did a few things you might not expect. From breakfast to team lunches, from pilates to cooking lessons, from time off for voluntary work to company socials.

We believe that the space we work in is important. We’ve created beautiful, innovative workspaces that reflect our culture and values, and are confident that we will once again have a very vibrant work environment when we return to some level of normality.

What happens next?

We’re building a global product with a global team that’s full of world-class talent. Our hiring process is designed to let your talent shine and for us to get to know each other so we know we’re the right fit.

  1. When we receive your application, it’s reviewed by one of your peers to see if your experience and skills are a match for what we’re looking for in the role. If they are, one of our Talent team will get in touch for a chat. If you’re a developer, it’s great to see some of your sample code via a Github, Stackoverflow, or BitBucket profile.
  2. For most roles we’ll then ask you to complete a tech assignment or task; or maybe to provide some sample code.
  3. The final step is to meet the team: mainly your team but also people from other teams, including the leadership team. We respect your time so this can happen all in one day or over a couple of visits.
