Backend Engineer

Salary Competitive

Instead of treating security as a necessary burden for users, we set out to create a seamless and convenient experience. Help us on our mission to build the smartest security system existing to date and join the Kisi Krew in Stockholm!


Access every thing. As one of the pioneers in the Security Internet of Things sector, Kisi's mission is to build cloud based security systems to allow business to manage access to their offices and everything within from the cloud. Being both a hardware and a software startup means we work on every layer of the stack: from low-level Bluetooth and NFC protocols all the way to our security OS in the cloud. Sounds like something you want to be a part of? 

We're looking for someone who's genuinely interested in becoming part of our mission to disrupt a century old industry!

Your tasks as a backend developer of Kisi will be a lot of things, but never dull.


  • Build highly robust and scalable cloud endpoints used by hundreds of thousands of users from all over the world
  • Build data pipelines to evaluate and analyze data streams and detect anomalous patterns and security concerns
  • Improve the toolkit around releasing new versions incl. automatic status updates, release notes and regression testing
  • Measure endpoint performance metrics and improve degradations to alert ahead of failure

What we're looking for is a team player that excels at their job.

- A humble team player
- Who's very proficient with Golang, Ruby, Scala or Java
- And knows how to write good code: clean, modular, tested, scalable
- Well versed in the field: cutting edge tech and the right tools for the job
- And who communicates with meaning

We're a small, yet very diverse and motivated team working from Sweden and the US.

- We love our product, and we’d love to have more people share our passion for taking access control to the 21st century
- We’re fun to work with and geeky at heart
- We’ll challenge you, as you’ll be working together with both web and embedded developers! We’ll make sure you feel that you learn something every single day.
- Change is part of our culture, as we always try to improve whatever it is we're doing

Looking forward hearing from you!

Working at
Kisi

Kisi makes keys easy. We build mobile access systems that let businesses enter, share and monitor their physical spaces. We envision a world in which access is fully digitized, easy to manage, and not constrained by mechanical objects – keys are so 1989! We are a seed-funded and have offices on both sides of the phone. Our headquarter is in Brooklyn, NY (USA) and our product team is based out of Stockholm, Sweden – Europe’s premiere startup hub. We are a multinational, driven team working from NYC and Stockholm. We do primarily tech in our Stockholm-office and sales/marketing/admin in the NYC-office. It is a hard industry to become a player in, and selling hardware is always difficult. We really like to get our hands dirty, after all, we are software people working with hardware.   Although we all work in different offices and with different projects, we share what we are currently working on to ensure that everyone knows what they’re doing, why they’re doing it and what deadlines need to be met. We tend to work at the office all day, to make sure we get stuff done. Other than a little bit of structure, we keep an informal tone within the team, and we value open communication. At Kisi, we are long-term focused: we’re building long-term relationships with our customers. Plus, we want people to think no longer of keys. That obviously requires time.
