Job Description:

The Multipass team is hiring a Software Engineer to join our distributed team. We greatly value quality in our code, and great user experience.

Multipass is published for macOS, Windows, and also Linux. Think of it as a workstation mini-cloud. At its simplest you can simply saymultipass launch and you will get a new VM on your workstation. You can feed that VM data, just as you would on a public cloud like AWS, Azure or GCP.

The goal is not to be a full cloud of course. The goal is to give developers a local cloud on their workstation, which they can use to run builds in the background, or to try cloud appliances, or to test their own cloud deployments and cloud-init scripts, free of charge. People sometimes use it as a build farm on a shared server, for example.

As a Software Engineer you are expected to play a leadership role designing, mentoring, reviewing and of course coding.

Location: This is a remote position available in the EMEA region only.

• Foster the open source community and support customers when needed
• Travel internationally for up to two weeks, twice a year, for company events

What we are looking for in you

• Cross-platform development experience on macOS and/or Windows
• Expertise in modern C++ development
• Experience with software testing and test-driven development
• Extremely high personal standards for code quality, testing and design
• Knowledge of hypervisor technologies such as Hyper-V, VirtualBox, KVM, and QEMU
• Open source experience and involvement
• Knowledge of CI systems a plus
• Capacity to learn quickly about new systems and techniques
• Excellent communication skills in English - both verbal and written
• Bachelor’s or equivalent in Computer Science, STEM or similar degree

What we offer you

We revisit compensation annually (and more often for graduates and associates) to ensure we recognise outstanding performance. In addition to base pay, we offer a performance-driven annual bonus. We provide all team members with additional benefits, which reflect our values and ideals. We balance our programs to meet local needs and ensure fairness globally.
