Systems Engineers

Ocean Infinity; Southampton; On-site; GBP 65,000 - 90,000; Full time

Job summary

Ocean Infinity is seeking Systems Engineers to design, integrate, and deliver marine robotic platforms across the full lifecycle. You will work with mechanical, electrical, software and operations teams to turn ideas into field-proven capabilities, supporting deployments and sea trials in demanding ocean environments.

You will own system architecture, maintain documentation, and lead trades and design evaluations while collaborating across disciplines to ensure reliable, integrated solutions.

Qualifications

• Experience across the full lifecycle of systems engineering.
• Ability to interpret and refine system-level designs, interfaces and behaviours.
• Hands-on testing, integration, and field deployments in real-world environments.
• Clear communication across mechanical, electrical, software and operations teams.
• Structured, methodical work with emphasis on reliability and traceability.

Responsibilities

• Own system architecture and manage system-level requirements and interfaces across platforms.
• Maintain and control requirements sets, ICDs, and system design descriptions reflecting real-world needs.
• Lead system-level trade studies, decompositions, and design evaluations balancing feasibility and risk.
• Support full lifecycle delivery from concept through deployment including configuration control.
• Drive hands-on hardware/software integration and sea-trial support with cross-functional teams.

Job description

We are seeking Systems Engineers to help design, integrate, and deliver the next generation of marine robotic platforms, working across the full lifecycle from concept and requirements capture through to integration, verification, and deployment. You’ll combine systems thinking with hands‑on engineering, collaborating closely with mechanical, electrical, software, and operations teams to turn ideas into field‑proven capability. You’ll be embedded in the engineering team, contributing directly to builds, integration, troubleshooting, and sea trials to ensure complex, multi‑disciplinary systems operate reliably in demanding real‑world environments.

These roles combine:

• Systems architecture & requirements ownership — shaping interfaces, behaviours, and system‑level design decisions
• Cross‑disciplinary engineering — working with hardware, software, and operations to deliver cohesive, integrated systems
• Operationally grounded delivery — ensuring designs are validated through real‑world testing, trials, and iterative improvement

You will help maintain a coherent system vision while supporting rapid development cycles, prototype evolution, and continuous field deployment. The role suits someone who thrives at the intersection of engineering design, practical integration, and operational delivery — someone who communicates clearly, builds technical credibility, and enjoys seeing their work operate in the ocean, not just on paper.

What you will be doing

• Own system architecture — define and manage system‑level requirements, interfaces, and architecture across USV and AUV platforms, ensuring clarity and alignment across engineering teams
• Maintain system documentation — develop and control requirements sets, ICDs, and system design descriptions that accurately reflect real‑world behaviour and operational needs
• Lead system‑level decisions — run trade studies, requirement decompositions, and design evaluations, balancing feasibility, risk, and operational constraints
• Support full lifecycle delivery — contribute from concept through deployment, including integration, verification, validation, configuration control, and change management
• Drive hands‑on integration and trials — participate in hardware/software integration, testing, troubleshooting, and support sea trials and deployments, working closely with cross‑functional teams and customers

Who you are

• Experienced in systems engineering across the full lifecycle, with clear ownership of requirements, architecture, integration, and verification activities
• Technically strong, with the ability to interpret, challenge, and refine system‑level designs, interfaces, and behaviours across mechanical, electrical, and software domains
• Hands‑on, comfortable working with hardware, debugging integration issues, and supporting real‑world testing and trials
• A clear communicator who can align diverse engineering teams, operational users, and external stakeholders around system‑level priorities and decisions
• Structured and methodical, with a strong focus on reliability, traceability, and delivering systems that work in high‑consequence environments

Desirable

• Understanding of navigation, control systems, and sensor fusion, particularly in autonomous or robotic platforms
• Experience with communication and networking systems such as acoustic modems, RF, or satellite communications
• Background working with USVs, AUVs, or other marine or autonomous systems
• Knowledge of model‑based systems engineering approaches and tools such as SysML

Given the nature of the work, this role requires you to obtain and maintain the appropriate level of UK national security clearance. You must be willing and able to undergo the necessary security vetting process, and continued employment in the role may be subject to maintaining the required clearance. Security vetting will be conducted in accordance with the requirements and standards set by United Kingdom Security Vetting (UKSV). Further information on UK security clearance levels, eligibility, and the vetting process can be found on the UK Government website: United Kingdom Security Vetting: Applicant
