Job Description

At Mimo, we believe that coding can open doors to careers and opportunities like few other skills. That’s why we’ve rallied around the common goal of making coding universally accessible.

We’re looking for a backend developer to join our cross-functional web team. You’ll build the business logic and protocols that deliver flexible flows, scale highly distributed systems, and continuously improve our infrastructure to help us provide the most accessible and enjoyable way to learn to code to our users.

What you’ll be doing

  • You’ll design, build, and ship major user-facing engagement features in collaboration with product managers, designers, and developers, using C# and ASP.NET Core with some TypeScript sprinkled on top for some microservices. 
  • You’ll develop backend components in conjunction with SQL Server, the underlying database on top of Entity Framework Core as ORM.
  • You’ll design scalable REST APIs and background jobs that support the growth of the Mimo App and Web version.
  • You’ll build and operate infrastructure, toolset, and deployment pipelines, taking operational ownership of the services.


You’ll thrive in this role if

  • You’re a seasoned developer. You have five (or more) years of experience as a backend developer shipping features for large-scale and real-time applications using C# and ASP.NET Core, building consumer-facing products.
  • You’ve built and maintained APIs. You hold yourself and others to a high bar when working with production systems, bringing a sound understanding of API design and best practices.
  • You care about code quality. You follow engineering best practices like code reviews to ensure and maintain excellent application performance and code quality.
  • You take the lead to ensure reliability. Practical experience securing, monitoring, log analysis, and conducting investigations in cloud-based environments (we use GCP).
  • You bring excellent attention to detail. You’ll put the user first when reasoning trade-offs while caring deeply about close attention to detail.
  • You ooze the values of the DevOps mindset.You’re intensely curious and passionate about running software in DevOps environments and eager to explore more about DevOps and SRE.
  • You know a thing or two about architecture, containerization, and orchestration. You’re keen to learn/or use container systems like Docker and/or Platform as a Service.
  • You have a sense of ownership. You believe in solving a problem entirely rather than simply shipping a solution. You operate autonomously and follow through on your commitments.

How we work

  • For this role, we ask you to be located adjacent to Eastern European Time (UTC ±0 to UTC +2).
  • If you’re located outside this time zone range and want to move to the company’s official headquarters in Austria, we’ll handle the work permit process and cover travel expenses.
  • If you prefer to work outside your home, we offer a physical location in Vienna and co-working stipends in other cities.
  • We love working async. You can set your own pace and schedule.

Our global perks and benefits

  • We have a remote-first mentality and give everyone a home-office budget.
  • 25 days of paid vacation in addition to your local public holidays and paid sick leave.
  • We sponsor team retreats throughout Europe and remote-friendly activities, like hack weeks and coffee breaks.
  • To further develop yourself, use our €1k growth budget for books, online courses, conferences, or anything else that supports your development.
  • To give our menstruating team members the time off to cater to their health when needed during their menstrual cycle, we offer up to 2 days of paid menstrual leave per month.
  • Your annual gross salary will be €66k gross annually, which will automatically increase by 5% yearly. No questions asked.
  • The chance to build a world-class product, positively impact millions of aspiring developers, and be a virtual owner of the company with equity (phantom stock).

Our 4-step hiring process, in a nutshell

  • You’ll first have a video-call with a member of the People team for a quick get-to-know chat.
  • Then, you’ll be given a take-home challengeto work on. Don’t worry; we know you have many things on your plate and good things take time. You won’t be given a deadline.
  • Next up is the technical interview to show off your skills to the hiring manager.
  • Lastly, you’ll meet your potential future peersfor a laid-back conversation.
  • If everything goes silky smooth, you’d be receiving an offer from us shortly after. Fingers crossed!
