Senior Sytem Engineer - Systems

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 the NAS appliance platform- the Linux-based system that runs in customer environments across physical hardware, virtualised infrastructure, and cloud platforms.
Responsibilities:
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.
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.
You operate with high autonomy within your domain and are accountable for production-grade outcomes.
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.
Requirements:
7-10 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.
