The listing, marked up

Nothing in the wording of this listing tripped a check. The scores above still judge how complete and coherent it is.

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1200+ colleagues in more than 80 countries and very few office based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution.

The company is founder led, profitable and growing.

We are hiring a software architect for Canonical LXD and MicroCloud.

Our goal is to make clusters of compute, with system containers or virtual machines, "just work". It should be trivial to stand up a small cloud using one, two or twenty servers. This is a challenging exercise in distributed systems, virtualisation, container technology, networking and storage. As with the Ubuntu desktop, our goal is to make it easy and to make it reliable for people to focus on the things that really matter to them rather than the OS and infrastructure.

LXD is a modern Golang system container and virtual machine orchestrator widely used on Ubuntu, ChromeOS and other Linux platforms. LXD engineering spans the entire software stack from low-level kernel work on namespaces, confinement, security, filesystems, VMMs and networking, to the high level management REST API and CLI. As a software architect, you will drive the architecture, design and evolution of LXD, and also Canonical MicroCloud which combines LXD with Ceph and OVN to make a lean, easy to use and resilient cluster-scale cloud infrastructure.

We are looking for an outstanding software architect and engineer with experience in Golang and C, with the leadership qualities needed to rally a team to ship outstanding products. Knowledge of modern cloud infrastructure offerings, their APIs and their underlying technologies is a must.

This is an opportunity for someone who wants to have a meaningful impact on modern cloud computing technologies. Canonical offers a fun, fast-paced team environment and a career full of learning and development.

Location: This is a home-based position available in EMEA and the Americas.

The role entails

• Leadership of the LXD and MicroCloud architecture

• Mentor, develop and advise colleagues in their career progression

• Develop in Golang and C

• Review code produced by other engineers

• Ensure the product is secure and performant

• Display technical leadership in Canonical and our communities

What we are looking for in you

• An exceptional academic track record from both high school and university

• Well-organized, self-starting and able to deliver to schedule

• Professional manner in interacting with colleagues, partners, and community

• Experience with Go and C

• Experience with storage, networking and virtualization

• Experience with container technologies

• Experience with concurrent, distributed systems

• Conscientiousness and detail orientation, with a focus on performance

• Professional written and spoken English

• Experience with Linux (Debian or Ubuntu preferred)

• Excellent interpersonal skills, curiosity, flexibility, and accountability

How this was produced

Highlights are found by rule, not by a model: each one is a phrase matched at a known position, and every note is a template we wrote. The two scores come from a typed-decision model (Jev) that reads the listing against the official role definition and real listings for the same role, and returns probabilities rather than prose — it never writes any of the words on this page, and never chooses what to highlight.

Deterministic penalty applied to the HR score: 16 points (from 55 before penalties). Reviewed 21 Sep 2026.
