London, England, United Kingdom · Development expand job description ↓


We're looking for a developer experienced with Rails and JavaScript and interested in expanding into new technologies to join our team in London. You’ll work with our clients to build great products that delight users while using weekly investment time to contribute to our community and embetter thoughtbot.

As a member of the thoughtbot London team, you will also become a member of our global thoughtbot community. We are almost 100 designers and developers in six offices around the world (Boston, San Francisco, New York, Raleigh, Austin, and London).

About thoughtbot

thoughtbot works with companies in every step of the process to help identify and solve problems. We lead and participate in product design sprints, build high-quality apps, and then deploy them. We use emerging and effective technologies and methods on both internal and client projects. We believe there is always a better way to do our work, and we want to find it and share it with as many people as possible.

Additionally, we maintain an inclusive work environment where everyone can thrive professionally, as well as have full lives outside of work. thoughtbot does not discriminate on the basis of race, sex, color, religion, age, national origin, marital status, disability, veteran status, genetic information, sexual orientation, gender identity, or any other reason prohibited by law in provision of employment opportunities and benefits.

thoughtbot web developers are able to rapidly build high-quality, test-driven, Ruby on Rails applications. Well-qualified candidates will have an excellent knowledge of HTML, CSS, JavaScript, debugging, refactoring, design patterns, and other programming practices.

While Rails experience is a must, we are also rapidly expanding our work into other languages and frameworks such as Go, Swift, Elixir, Python, React, Ember, and Node.js. Experience or interest in these technologies is a big plus.

Very well-qualified candidates will also have experience with consulting, and have a proven track record of attracting potential customers.


In addition to a competitive salary, you will receive company-matched pension contributions and private health insurance. For new parents we offer additional paid leave on top of your statutory rights.

Our team works in a relaxed and educational environment to develop excellent products for our clients. We work a sustainable pace of 40 hours/week, consulting for clients four days/week. We also like to learn. Everything we do is predicated on having a great team and a culture of growing. We use the latest technologies and are always down to try new methods on both internal and client projects.

We like to keep ourselves happy while we work. Our offices are fully stocked with everything from tasty snacks to neat little notebooks, and we organise quarterly social activities.


On Fridays, we have "investment time" to learn new tools and techniques, work on open source, create new products, write blog posts, and try to make ourselves, each other, and the community better. We top this off with a double hack day at the end of the year.
