About the role

Keypup helps engineering organizations gain clearer visibility and be better organized at all levels, from the developer to the CTO. We believe that development teams deserve a better recognition and acknowledgement, and that more often than not, stakeholders are prevented from having a clear understanding of the development effort by and large.

Why do we want you?

Keypup is a fast-growing, vibrant company using state of the art technologies.

We are looking for passionate engineers to work on expanding our data processing flows, reporting algorithms and API capabilities. If working on core processing logic and microservice architectures gets you excited, this is the right opportunity.

What will you do?

Build great experiences

Work closely with marketing and product to build visually stunning experiences for developers.

Take ownership

Drive your projects from A to Z with a high degree of autonomy. We don't micromanage.

Bring your own ideas

We encourage feedback and creative solutions. Keypup is made for you, so your voice matters.

Improve standards

We hate manual processes. If you love building automations to improve dev-flow, you'll love it here.

Help the community

Share knowledge on Reddit, Indie Hackers, and publish technical articles to help the dev world.

Why join us?

Developer-First

It's a product for developers made by developers. We - engineers - are the first customers of Keypup.

Early Stage Impact

Most of the work lies ahead of us, and you have the opportunity to shape the future of Keypup with us.

Absolute Autonomy

If you work with us it means we trust you, and therefore we do not need to look over your shoulder.

Passion for Dev

We are passionate about what we do and strive to help the development community as a whole.

Total Flexibility

Remote work, office work or your preferred mix. We are a flexible engineering org.

The skills you need

As an engineer you must:

  • Have 4+ years of experience in React (or Angular...in case you wish to switch back to the light side :p)
  • Have experience with databases, relational or NoSQL
  • Have experience designing and implementing APIs (REST, GraphQL, ...)
  • Have experience with microservice and event-messaging architectures

As an individual you must be:

  • Proficient in english. We work, develop and joke in english!
  • Nice, open-minded and inclusive
  • Willing to learn: we embrace mistakes as a good way to learn (keyword here is learn :p)
  • Product oriented: you are the first customer. You do this product for yourself. If you think something in the UI is ugly then it certainly is for everyone. Good news! You can do something about it.
  • Autonomous: the knowledge we retain is the one we search for.
  • A thinker: there is no point in rushing into code. It takes some thinking to design the best implementations.
  • Test-driven: good tests are essential to keep the codebase maintainable
  • Enjoying open source: we use, contribute and create open source projects. We hope that's a passion you share as well.
