Kisi is a security platform with offices in Brooklyn and Stockholm and a global remote team spanning from America, Europe, Africa and Asia. We create hardware and software that helps businesses connect and control their spaces through the cloud.

About the role:

Your tasks as a backend developer of Kisi will be a lot of things, but never dull. In helping us build a highly robust and scalable public API (used by hundreds of thousands of users from all over the world!), you will:

  • Implement new features and help define and tackle projects big and small
  • Collaborate with our web, mobile and hardware teams
  • Design and maintain internal frameworks and standards
  • Work on improving security and performance of endpoints and background jobs
  • Work on internal tooling for logging, error reporting, releasing, testing etc.

We move fast, plan frequently, release to production daily and keep our meetings short. Our API is currently a Rails monolith running on Heroku & GCP, and we’re documenting it with OpenAPI 3. Familiarity with this stack is a big plus!


  • Solid experience with Ruby and Ruby on Rails (or a similar language/framework)
  • You’ve mastered the latest technologies and you’re experienced with modern tools and workflows
  • You are well versed in writing good code: clean, modular, tested, scalable
  • You love cutting edge tech and you’re passionate about working on a product that is solving real world problems
  • High level of communication and teamwork skills

Why Kisi?

  • Real impact: your contributions matter, and your code will reach customers within a few weeks of onboarding. We have quick turnaround times and enjoy working under reasonable pressure.
  • You’re in for the full picture, from understanding and enhancing product requirements to building and verifying the hardware and software product that corresponds to them.
  • Work hard, play hard. Competitive salary, wellness program, insurances, yearly company bootcamps, but also a lot of heavy lifting and crunching. We want to go above and beyond.
  • Anything but ordinary. We’re a fun and international crew with offices in Brooklyn and Sdermalm, and an office atmosphere that’s often described as too much.
