Senior Backend Developer

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 app 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#, ASP.NET Core, and TypeScript.
• 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 APIs and services that support the growth of the Mimo platform.
• 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 three (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 have a bias for action. You have a strong sense of urgency; when you see a problem, you solve it. You don't have time to waste on analysis paralysis and prefer to learn from your mistakes as you go.
• 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 pay excellent attention to detail. When reasoning trade-offs, you’ll put the user first and care deeply about the details.
• You ooze the values of the DevOps mindset. You’re intensely curious and passionate about running software in DevOps environments and eager to explore DevOps and SRE more.
• You know a thing or two about architecture, containerization, and orchestration. You’re keen to learn/or use container systems like Docker, Kubernetes, 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 €69k, automatically increasing 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 challenge to 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 is the technical interview to show your skills to the hiring manager.
• Lastly, you’ll meet your potential future peers for a laid-back conversation.
• If everything goes smoothly, you’ll receive an offer from us shortly after. Fingers crossed!
