Software Engineer Jobs

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 1000+ colleagues in 70+ 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.

HPC is an important and technically challenging compute domain, with specialised tooling and a very high expectation of precision, efficiency and automation. This role is for a software engineer to join our HPC team to deliver an outstanding HPC experience – from bare metal to public cloud – as part of the broader Ubuntu platform. We are looking for a range of skills and experience, and will work on everything from the kernel to Debian packaging, but the heart of our effort will be Python software development for automation of key software in the HPC sphere. Our focus is on delivering a world class experience for the operation of the HPC cluster itself. You will be part of the team that delivers charms that deploy and manage the HPC cluster and provide HPC software packages.

To succeed in this application you must be outstanding at maths and sciences, have built high quality software, have learned about open source ideally by working on it directly, and be looking for an engineering role with a company that makes mission‑critical products for the global market. You should also be familiar with the open source environment, and want to build products in partnership with a community. Ideally, you should have some experience of high performance computing environments and a desire to unlock HPC for the world.

For this role you must have experience with Python. Experience in HPC environments is a strong advantage. Familiarity with HPC hardware and software is also a strong advantage – delivering great experiences with Infiniband, RDMA, CUDA, MPI, Slurm, Lustre, Singularity and related technologies will be central to this team’s work. It will also be advantageous to have experience with Docker image design and operations, and public cloud image design and operations.
