We are an engineering office for software. We develop web-based software and specialise in complex portals and platforms that are simple to use, easy to find and work perfectly on any device. Our focus thereby always lies on the quality and security. 100% line coverage is the norm for our unit tests. Thanks to our location in Wallisellen near Zurich, we maintain short communication channels to our customers.

We are young, highly educated and our know-how covers the newest web technologies and systems. In today's fast-paced digital world we consider staying up-to-date and continuously educating ourselves as crucial. We don't develop cookie-cutter solutions, but approach every project as its own individual thing. This is why our projects are as unique as our customers.

We are looking for you as a software engineer to support our team.

Your mission

As an Open Source Software Developer at Renuo, you'll work to build new product features and keep our apps fast, secure, and reliable. Depending on your interests and skills, you may do more frontend work, using HTML, CSS and JavaScript, or more backend work, where our primary technology is Ruby on Rails. We also use other technologies like Flutter or React Native for mobile development.

In particular, this means:


  • Software engineering using web technologies (Ruby on Rails / React / TypeScript / JavaScript / HTML5 / CSS3)

  • Requirements engineering, technical assistance and advisory of clients

  • Database design using SQL (Postgres, MySQL)

  • Participation in project management (Scrum)

We're not into heroics or all-nighters: this is a 40-hour per week job (or less, if you like to).

Our expectations

We're looking for candidates with (at least) a Bachelor Degree.
You should be experienced in the framework Ruby and with the staples of full-stack web development: HTTP, HTML, JavaScript, and CSS.
If you lack any of this, that’s no problem. We will teach you! We care about what you can do and how you do it, not about how you got here.

In particular, this means:


  • You've got an engineering degree (at least B.Sc.)

  • You have a lot of programming experience

  • You're at home in the web (HTML5, CSS3, JavaScript)

  • Nice to have: Ruby on Rails, Python, Elixir, Rust

We value people who can take a stand yet commit even when they disagree. We subject ideas to rigorous consideration and challenge each other, but all remember that we’re here for the same purpose: to do good work together. That comes with direct feedback, openness to each others’ experience, and willingness to show up for each other as well as for the technical work at hand.

This is not a remote job. You are required to be located somewhere in Switzerland and that you come to the office once or twice a week. All the other days are up to you: you’re free to work where you work best: our office, home office, co-working space, coffeeshops.

What we offer

Among our benefits there are:


  • 10% investment time: You can spend 10% of your working time on discovering new technologies and learning new things. This time is paid and is yours. The company might force you to use this time for some company events like a learning week or a learning day.

  • Learning days: At least once every quarter, we organise a shorter version of the learning week. A learning day focuses on one specific topic, and everyone is free to participate or not

  • Learning weeks: We spend one week every year learning and growing together. This week is meant to do team-building, know each other a bit better, and learn new fancy technologies. Do all these things that the day-to-day work doesn’t allow.

  • Free coffee, free snacks, free beer...something else?: Whatever makes you happy when you are at the office is free. You can just ask to get whatever you think will make your day better. Do you want a small snack? There’s always a wallet available in the office with some money in it. Just grab it and buy whatever you want!

  • 20% company profits distributed: We share 20% of company profits to all our employees every year. Another 10% goes to charity and open source projects.

  • Flexible working hours: For us, this does not only mean that you decide when you want to work, but also how much. How salary is based on the hours worked and you’ll get a flexible hours/week contract. You decide how much you want to work.

  • We lead our enterprise with heart

  • We gladly hand over responsibility and leave you with much autonomy

  • We have as little rules as necessary

Apply now

Please submit an application with a CV and a cover letter that tells us about yourself and about what you can bring to Renuo. Tell us about something you’ve done, something that’s relevant to the kind of work we do, something that excites you. Overall, be descriptive, but don’t write a novel — 500 words or so is plenty.

If you've participated in open source work of any kind, please include links to pull requests, bug reports, feature pitches, or any other public engagement. Open-source participation is by no means a requirement, but if it's something you've done, we'd like to look at it.

We will reply to all applications. If you pass the first screening, you’ll be asked to come to our office for a day to meet and get to know each other. You’ll also be asked to do one or more technical exercises. Please consider whether you’d be willing to dedicate that time before applying.

Samuel Steiner ([email protected]) is looking forward to hear from you!
