Project: C4DASI – Foundational C4 Design Support

Work Package: WP89 – Routing and Bearers

RFQ: 109100

Location: Canberra ACT, with occasional interstate travel for stakeholder engagement

Salary: AUD $190,000–$220,000 per annum

Security Clearance: NV2 minimum; PV preferred

Position Description A suitably experienced C4 Communications Engineer is required to support Joint Force Command, Control, Communications and Computers (C4) Foundation Design activities, addressing Defence’s information exchange needs across the Integrated Force and with coalition partners.

The role will develop logical, functional and physical designs to deliver C4 architectures that enable technical interoperability across the Joint Force for the 2029–2033 period.

Working within the Foundational Design team, the successful candidate will support the development of the Joint Force C4 system of systems, including wide area network and communications system requirements. The role will also develop system visualisations using digital modelling tools to support the foundational requirements of mission designs.

The work focuses on two layers of the C4 Representative Architecture:

- Routing: Network and transport development, security, protocols and standards.
- Bearers: Satellite communications and radio frequency technologies used in a military environment.

The work is classified Secret, with some technical design aspects requiring a Top Secret clearance.

Responsibilities

- Develop innovative Foundational C4 Design guidance to improve information exchange and technical integration across the Integrated Force.
- Support Joint mission designs and mission threads, including Electromagnetic Manoeuvre Warfare, Multi Domain Strike, Undersea Warfare, and Integrated Air and Missile Defence.
- Apply expert routing and bearer knowledge, together with an understanding of ADF Integrated Force operations up to Top Secret, to develop practical design guidance through structured logical processes.




- Lead the review and update of Foundational C4 Design guidance.
- Apply systems engineering processes and a mission engineering thread methodology to C4 design.
- Collaborate with Defence Group and Service stakeholders to develop force integration design artefacts.
- Support the preparation of Foundation Design submissions and briefs for senior committees, including the C4 Design Working Group and Information Setting Control Board, capability gate reviews and capability investment boards.
- Recommend improvements to the methods, processes and repositories used to collate C4 Design guidance.
- Work with the standards team to formalise design guidance into standards profiles.
- Collaborate on architecture views and data visualisations to describe current “As Is” and future “To Be” architectures.
- Apply Model Based Systems Engineering (MBSE) up to Secret classification to formalise outcomes and establish a repeatable engineering process for C4 design.
- Support key programs and projects in developing and applying design guidance.

Essential Requirements

- Understanding of and experience with the Open Systems Interconnection (OSI) reference model, with particular expertise and demonstrable experience across the transport through to physical layers.
- Understanding of Wide Area Network (WAN) standards and protocols, satellite communications (SATCOM), and radio frequency (RF) systems technologies.
- Understanding of and experience with ICT architectural views, including the Unified Architecture Framework (UAF), enterprise architectures and solution architectures.
- Hold a minimum NV2 security clearance.

Highly Desirable
- Experience in Defence capability development and/or sustainment activities.
- A personable, collaborative and team-focused approach, supported by demonstrable stakeholder engagement skills.
- Experience in C4 Systems of Systems Engineering and/or Model Based Systems Engineering.
- PV security clearance preferred.

Desirable
- Familiarity with Defence writing standards.
