Job duties include the design and implementation of embedded Linux platforms, multi-tier network architectures, and web-based management applications that together form the operational backbone of Q-Block Computing's hardware systems.Responsibilities
  • Design, build, and maintain embedded Linux system images for ARM-based compute modules using Yocto, Buildroot, or similar frameworks.
  • Architect and implement multi-tier LAN environments with isolated address spaces, managed Ethernet switching, VLANs, and QoS policies for reliable, low-latency delivery of control payloads.
  • Design and deploy network services such as DNS, DHCP, NFS, and time synchronization across tiered network topologies.
  • Design, develop, and maintain a web-based management application providing real-time device monitoring, topology visualization, and command distribution.
  • Develop Python, Bash, and Ansible automation for network provisioning, system deployment, and configuration management across growing device fleets.
  • Implement monitoring and observability tools to track network health, device status, and overall system performance.
  • Develop and execute quality assurance procedures for infrastructure systems; validate throughput, latency, and failover behaviour.
  • Write documentation for network topology, IP addressing schemes, switch configurations, and system build procedures.
  • Collaborate with cross-functional firmware, hardware, and systems teams.
  • Contribute to a culture of continuous learning and knowledge sharing within the team.
Qualification
  • Bachelor's degree in Computer Science, Computer Engineering, Information Technology, or a related field.
