About the role
We are expanding our Platform Engineering team with a Senior Software Engineer who thrives in deep systems work. This role sits at the core of Nasuni's NAS appliance platform—the Linux-based system that runs in customer environments across physical hardware, virtualised infrastructure, and cloud platforms. This is a role for engineers who: Build and debug operating-system-level software. Understand storage and filesystem internals. Write production-grade Python as a primary development language. Enjoy diagnosing complex Linux and I/O issues in real-world deployments. This role is not for application-only developers or infrastructure operators. It is for engineers who build and evolve system platforms.
Responsibilities:
- Design, develop, and maintain Linux systems software for the NAS appliance platform.
- Write production-quality Python code for system orchestration, automation, upgrade workflows, and platform services.
- Develop and maintain shell-based automation (Bash and similar scripting) for system provisioning, packaging, and operational tooling.
- Contribute to low-level integrations where C/C++ is required (preferred capability).
- Work with Linux internals, including systemd, memory management, storage stack, networking, and security configurations.
- Optimise filesystem and I/O performance (XFS, ext4). Develop packaging and release mechanisms (rpm/yum or equivalent).
- Write and maintain automated tests using pytest and CI pipelines.
- Debug multithreaded and I/O-intensive production issues.
- Collaborate with Support on high-severity escalations.
- Use AI-assisted development tools responsibly to improve debugging efficiency, log analysis, and workflow automation while validating outputs rigorously.
- Own design and implementation of subsystems within the NAS appliance platform.
- Design and develop Linux systems software in Python.
- Contribute to storage, upgrade, deployment, packaging, and lifecycle management components.
- Debug complex customer-reported issues across OS, storage, and virtualisation layers.
- Influence architecture decisions within the platform domain.
- Collaborate with QA, Support, and Cloud teams to deliver appliance-grade reliability.
Requirements:
- 8-14 years of experience building Linux-based systems or appliance-grade software.
- Strong production-level Python development experience (primary language).
- Strong understanding of Linux internals: systemd, memory, storage, networking, security.
- Experience working with filesystems such as XFS or ext4.
- Experience debugging multithreaded and I/O-intensive systems.
- Hands-on experience packaging, deploying, or maintaining system-level software.
- Experience writing and maintaining shell scripts (Bash or equivalent) for system automation.
- Experience designing and executing automated tests using pytest or similar frameworks.
- Experience working in virtualised environments (ESX, KVM, Hyper-V, or similar).
- Experience using AI-assisted development tools in debugging or automation workflows with demonstrated ability to validate and verify outputs.
Preferred Qualifications:
- Experience with C or C++ in systems-level development.
- Experience integrating Linux systems with AWS, Azure, or GCP.
- Familiarity with Jenkins, GitHub Actions, or CI/CD pipelines.
- Knowledge of networking protocols (TCP, UDP, HTTP).
- PostgreSQL experience in production systems.
- Experience contributing to open-source systems projects.
Ideal Qualifications:
- Experience building storage platforms, File systems, or unstructured data systems.
- Experience developing appliance software deployed in customer-managed environments.
- Experience optimising system performance at the OS or storage layer.
- Experience designing upgrade and lifecycle management mechanisms for distributed systems.
Experience Guidelines:
- 7-10 years total industry experience in systems or platform engineering.
- At least 5+ years working deeply in Linux systems development.
- At least 4+ years of production Python development in system-level contexts.
