Sonar Systems Engineer

A leading defence prime is seeking a talented Senior Systems Engineer to support the development of advanced sonar solutions for critical defence and maritime applications. You will play a key role in translating operational needs into system architectures, requirements, and validated technical solutions, working closely with multidisciplinary engineering teams throughout the system lifecycle.

Key Responsibilities

Systems Engineering & Architecture

• Perform functional analysis and decompose operational needs into sonar functional chains supporting incremental development and validation.
• Define and refine system architectures in collaboration with technical experts.
• Apply Model-Based Systems Engineering (MBSE) techniques to model system functions, behaviours, and interfaces.
• Maintain traceability between operational needs, architecture, requirements, and verification activities.

Requirements Management

• Develop, analyse, and decompose system requirements into subsystem-level specifications.
• Define functional, technical, performance, and interface requirements.
• Ensure requirements consistency, completeness, and traceability throughout the project lifecycle.

Cross-Functional Collaboration

• Lead technical workshops and co-engineering activities across software, hardware, algorithms, systems performance, networks, safety, cybersecurity, and operations teams.
• Support engineering trade-offs and technical decision-making across the solution.

Verification & Validation

• Define validation scenarios with Operations and IV&V teams.
• Ensure solutions are feasible, operable, and verifiable against customer and operational requirements.
• Contribute to system integration, testing, and engineering reviews.

Engineering Deliverables

• Produce key engineering artefacts including System Specifications (SSS), System Design Descriptions (SSDD), and Verification Compliance & Requirements Matrices (VCRM).
• Work within engineering data models using tools such as Capella, Polarion, and Jira.

Required Qualifications

• Engineering degree or equivalent Master’s/Bac+5 qualification, ideally in Systems Engineering, Electronics, Computer Engineering, Naval Engineering, or a related discipline.
• Experience delivering complex systems within an industrial environment.
• Strong background in:
• Functional Analysis
• Requirements Management
• Verification & Validation
• Proven ability to work effectively within multidisciplinary engineering teams.
• Strong analytical, stakeholder engagement, and problem-solving skills.
• Experience within defence, maritime, sonar, sensor, radar, or mission-critical systems.
• Knowledge of MBSE and the Arcadia methodology.
• Experience with the Orchestra suite, particularly Capella.
• Familiarity with Polarion, Jira, and requirements management tools.
• Understanding of safety, cybersecurity, and networked systems.
