  • Enhance platform functionality for satellite scheduling, data delivery, and visualisation applications.
  • Maintain and improve software interfaces to phased-array antennas and traditional dish-based ground stations.
  • Implement incremental feature updates in collaboration with the Digital, DSP, and Systems Engineering teams.
  • Maintain and extend infrastructure automation, deployment pipelines, and monitoring tools.
  • Deploy and manage systems across Azure Cloud and on-premise hardware.
  • Contribute to system security, performance testing, and documentation for production environments.

Required Qualifications & Experience:

  • Bachelor's degree in Computer Science, Software Engineering, or related field.
  • 4+ years of experience in software engineering or systems operations for complex distributed systems.
  • Proficiency in Python and C++, with ability to debug, maintain, and refactor production code.
  • Hands-on experience with Kubernetes, Docker, and CI/CD tools such as Azure DevOps or GitHub Actions.
  • Strong knowledge of Linux environments, networking fundamentals, and virtual infrastructure.
  • Experience maintaining monitoring and logging systems (Grafana, Prometheus, Airflow, etc).
  • Familiarity with data pipelines, APIs, and integration workflows using Kafka, PostgreSQL, and Clickhouse.
  • Understanding of DevOps and platform operations best practices.

Desirable Skills & Attributes:

  • Exposure to satellite ground systems, RF communications, or space mission operations.
  • Experience in hybrid deployments (cloud + bare metal) and high-availability system operations.
  • Understanding of signal processing or telemetry workflows.
  • Interest in space technology, electronics, or radio astronomy that complements software expertise.
  • Ability to work independently, troubleshoot effectively, and deliver incremental improvements to live systems.

Why join QSAT?

  • Maintain and enhance systems at the cutting edge of satellite communications and RF sensing.
  • Collaborate with world-class engineers in Australia's leading space technology ecosystem.
  • Enjoy a flexible, impact-driven work culture with autonomy and technical ownership.
