Defence Systems Technologist
We're looking for an experienced Defence Systems Technologist who can turn complex operational problems into coherent, integrated and deliverable capability. You'll work with military users, programme teams, architects, engineers and senior stakeholders, connecting mission needs with the wider Defence technology ecosystem.
This is more than a conventional solution architecture role. You'll combine mission understanding, systems thinking and sound technology judgement to clarify options, expose dependencies and help people make better decisions. Your architecture will not exist simply to create diagrams; it will help turn strategic intent into practical delivery.
What you’ll do
- Work with military users and stakeholders to understand operational needs, constraints and measures of success.
- Apply systems thinking across people, processes, information, technology and organisations, decomposing complex requirements into capabilities, functions, services, systems and interfaces.
- Develop mission, system and solution architecture views that show how capabilities fit within the wider Defence ecosystem.
- Identify dependencies across networks, cloud, data, identity, security, gateways, infrastructure and related programmes, considering interoperability and information exchange from the outset.
- Develop and assess technical options, making risks, trade-offs, gaps and opportunities for reuse clear to decision-makers.
- Support governance, assurance, procurement and supplier discussions, while working with delivery teams to keep architectural intent achievable.
- Explain complex technical issues clearly to technical and non-technical audiences and challenge assumptions constructively.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.

Experience with Defence or NATO architecture frameworks, interoperability, coalition environments, secure information exchange, Cross-Domain Solutions, SysML, UML or ArchiMate would be useful, but it is not a checklist. We care most about how you think, how quickly you understand difficult problems and how effectively you connect operational needs with technical reality.
Requirements
We're interested in people who bring:
- Experience of military or defence systems gained through the Armed Forces, government, industry or a related environment.
- Experience in systems engineering, architecture, mission engineering, capability development or technical consultancy.
- Strong requirements capture, analysis and decomposition skills, with an understanding of system-of-systems environments.
- The ability to move confidently between strategic intent and technical detail, build trusted relationships and facilitate productive workshops.
- Strong technical judgement, intellectual curiosity and clear written and verbal communication.
- Eligibility to obtain and maintain Security Check (SC) clearance, with the potential to obtain Developed Vetting (DV).
