Job description

All Orbits, All Planets - Join us on our journey

Gilmour Space is the leading Australian rocket company, pioneering next-generation hybrid propulsion technologies for small satellite launch vehicles.

Are you a creative and experiencedSenior GNC Engineer looking for a dynamic role where your skills will make a real impact? Have you ever dreamt of building rockets right here in Australia? Well now’s your chance! The Senior GNC Engineer is responsible for designing algorithms and implementing flight-critical software for rocket systems that will deliver satellites to orbit! You will work with a talented team of engineers to develop, analyse, test and operate launch vehicles, and its subsystems, with the aim of ensuring highly reliable flight. So, what are you waiting for? Join us and be a part of a forward-thinking team dedicated to pushing the boundaries of space exploration and let’s send Australia to Space together!

How you will contribute to our mission in getting Australia to space:

The below is designed to give you an idea of the role you will play. There will be many more exciting and innovative things to do:

Leadership:

• Serve as a Responsible Engineer for GNC products, conducting technical assessments such as concept studies, trade studies, and COTS solution analyses.
• Follow and participate in product development processes, including requirements definition, design, verification, and validation.
• Represent the GNC discipline in program reviews, technical exchanges, and stakeholder briefings.
• Establish best practices for GNC verification and validation (V&V), including hardware-in-the-loop testing, Monte Carlo simulations, and operational rehearsals.
• Integrate GNC subsystems with avionics, software, mechanical, propulsion, and mission operations teams to ensure system-level performance and reliability.
• Build, lead, and mentor a high-performing GNC team.
• Ensure that all engineering activities adhere to company policies, plans, and procedures and fulfill other duties as requested by management.

Technical:

• Developing linear and non-linear models of control system plant dynamics and effectors for launch vehicles.
• Iterating and improving upon the existing flight algorithm stack for navigation, guidance and control.
• Drive continuous improvement of tools, automation, and analytical pipelines supporting design, analysis, and operations.
• Analysing performance, stability and robustness of flight algorithms.
• Mission design and optimisation of launch vehicle trajectories.
• Designing and implementing simulation and visualisation tools
• Using numerical methods to propagate complex uncertainty models (e.g. Monte Carlo methods).
• Conducting analyses and design studies for future vehicles in a multi-disciplinary team.
• Characterising the natural environments for launch vehicles including wind and space radiation.
• Applying data analysis techniques to validate models from test data.

Mandatory Qualifications, Skills and Experience:

• Minimum of a Bachelor’s (B.S.) degree in Physics or Aerospace / Aeronautical / Mechanical / Electrical Engineering or relevant STEM degree.
• 4+ years of experience in professional GNC, Flight Software or robotics design engineering settings (excluding internships).
• Proven ability to lead and collaborate effectively in a fast-paced, team-oriented environment, demonstrating resilience in high-stress situations and a supportive approach with team members.
• Demonstrated experience with programming in Python, MATLAB, or other high-level languages.
• Demonstrated experience with low-level development language (e.g. C++, C).
• Experience with git workflowsor equivalent version control system.
• Experience with software verification and validation, as well as working in a continuous integration environment.
• Experience working within a Systems Engineering framework.
• Ability to obtain NV1 Security Clearance.

Desired Qualifications, Skills and Experience:

We recognise you may not meet all of the below, but don’t let that deter you. We are always looking for hard workers to join our team, so what are you waiting for? Let’s send Australia to space:

• Strong command of control theory and proven experience in control systems design.
• Experience in launch vehicle, missile, UAV or satellite programs.
• Familiarity with Linux-based environments, scripting, and containerised toolchains.
• Understanding of sensor and actuator hardware (IMU, GNSS, EMA).

How to Apply:

Applicants must be an Australian Citizen/Permanent Resident or have an appropriate Australian work visa or work entitlements.
