Senior Multi-Platform Engineer (C#/Swift/Python)

Who we are
Memtime is one of the most successful early-stage startups in B2B SaaS, with thousands of customers in over 86 countries. We just got our Series A funding and are now scaling the company. Our mission is to become the new standard for tracking time — integrated with every project software worldwide.

How we work
We are an international team with a hybrid remote work culture and a headquarters office in Munich. At Memtime, we deal with time, which means we respect yours: Instead of endless meetings and compulsory attendance, we believe in well-designed collaboration that gives us a sense of self-efficacy and allows us to see the impact of our daily work through results.

Our Product
With our software for automatic activity tracking, we are the technology leader in our segment:

• Our software automatically records what you're working on (e.g. emails, 

  documents, websites, etc.) — so you can easily remember which customers/projects you spent your time on
• What makes our software especially employee-friendly: it stores all data exclusively on the user's device. No monitoring or surveillance features. Full privacy for the user
• We seamlessly integrate with any kind of project software, ERP system, or billing solution

About the team
Our Application Team is growing. We’re looking for a versatile, capable, and product-focused developer to help us evolve the core of our application across platforms.

This role focuses on the native development of the Memtime App for Windows (C#), macOS (Swift), and Linux (Python). Since the behavior of certain system-level functions varies across platforms, our core application is developed natively to ensure the best performance and user experience on each OS.

You’ll play a key role in building and improving the technology that powers our automatic time tracking.

What we are looking for in you

• Strong experience with either C# (Windows) or Swift (macOS) — one is required, and you're open to learning the other
• Willingness to work cross-platform and develop natively for Windows, macOS, and Linux

• Experience with or interest in Python for Linux development

• Solid understanding of SQL, especially with SQLite, which is used in the core application

• At least 5 years of professional software development experience

• Customer-oriented mindset and a pragmatic, solution-driven approach

• Team player who enjoys working across disciplines

• Fluent in English

Even better, but not required, if you

• Have experience developing native applications for more than one OS

• Are familiar with system-level integrations or OS-specific APIs

• Have worked with Python in Linux environments

• Have a basic understanding of cross-platform build tools or DevOps related to desktop app development

You will be

• Developing and maintaining the tracking functionality natively for:

  • Windows using C#

  • macOS using Swift

  • Linux using Python

• Working on platform-specific functionality that enables precise and efficient activity tracking
• Improving existing features and helping shape new ones at the system level
• Collaborating with engineers from other teams (front-end, cloud, infrastructure)
• Defining and refining architectural decisions for long-term maintainability

You will be working with

• C# (.NET) on Windows

• Swift on macOS

• Python on Linux

• SQLite as our embedded database

• Native APIs and OS-level integrations on each platform

Job details

• Fully remote

• Full-time, 40h / week

• Your choice of hardware

Interview process

• Please upload your CV (PDF file) in the application form (Cover letter optional)
• If your submission meets our expectations, we invite you to a first meeting to get to know each other (company, position, etc.)

• Next step is a short questionnaire

• If that goes well, you’ll be invited to a single 1.5-hour interview split into 2 parts:

  • Technical interview

  • Your questions

• If you pass the interview, we’ll make you an offer

Why you should apply
