Now, we’ve talked a lot about ourselves – but we’d love to hear more about you.

You will be:

• developing system-level Go code focused on storage drivers and virtualization technologies,

• writing and maintaining custom storage drivers for a cloud-native platform using LXD and LXC,

• collaborating within an agile team to design and implement a scalable cloud solution,

• Working close to the operating system, dealing directly with filesystems, kernels, and container runtimes.

• Building and fine-tuning containerized environments, with an emphasis on performance and resource management.

• Contributing to and working with open-source technologies and tools.

Requirements

Your profile:

• at least 4 years of experience in Go, with a strong grasp of Go’s concurrency model,

• 7+ years of software development experience in total,

• expert-level knowledge of Ubuntu/Linux system administration,

• 5+ years of experience in system-level programming,

• solid hands-on experience with LXD and LXC containers (not just Docker),

• deep understanding of container-host interactions, including CPU, memory, and disk I/O management,

• practical ability to configure networking, storage devices, and mounts in LXD environments,

• familiarity with version control systems (e.g., Git),

• version control systems, understanding of how Kubernetes manages memory and storage resources in clusters,

• confident working in and contributing to open-source environments,

• English level: B2–C1.

Nice to have:

• experience setting up or maintaining Kubernetes clusters,

• previous DevOps exposure or mindset,

• you’ve personally run your own K8s cluster or built infrastructure from the ground up,

• experience in C programming.

You’re a great fit if:

• you're not just a developer — you're a systems thinker who understands what’s happening under the hood,

• you’re comfortable working close to the metal, directly with low-level components and runtime environments,

• you thrive in environments where performance, scalability, and system integrity matter most.
