Performance Engineer

Performance Engineer

Location: Southampton – hybrid, 3 days per week on-site

Salary: £45-65K plus excellent benefits package

About the Opportunity

Our client is a fast-growing maritime technology business developingwind-assisted propulsion systems that help reducefuel consumption andemissions across global shipping.

They are now looking to appoint aPerformance Engineer to join their growing team. This is a rare opportunity for someone with strong experience working withreal-world engineering data,telemetry, or industrial systems to help shape how performance is measured, understood, and improved across a growing fleet of commercial vessels.

Working acrossengineering,software, and commercial teams, you will own the end-to-enddata and insight pipeline, designing how operational data flows from onboard systems through to internal engineering tools and customer-facing reporting. You will play a central role in ensuring performance is captured accurately and translated into meaningful insight that supports engineering improvement, reliability decisions, and validated fuel-saving claims.

Key Requirements

You will be an analytically strongPerformance Engineer, Data Engineer,Marine Performance Analyst,Industrial Data Engineer,Fleet Performance Engineer, or similar, with experience working withreal-world engineering or industrial data and turning complex information into clear, actionable insight. You should bring:

• Degree qualification inEngineering, Naval Architecture,Data Science,Physics, or a related technical discipline
• Solid experience working withreal-world engineering or industrial data
• Experience building and maintainingdata pipelines and processing workflows
• Strong analytical capability, with the ability to interpret complex datasets and translate them into clear insight
• Experience developingdashboards orreporting tools for both technical and non-technical users
• Exposure to data fromphysical systems such assensors,telemetry, orindustrial equipment
• Strong communication skills, with the ability to present data in a commercially meaningful way
• A proactive and structured approach, with the confidence to work in a fast-moving environment

Desirable experience includes:

• Experience withinmarine,energy, or other industrial environments
• Exposure toreliability analysis orperformance modelling
• Familiarity withscalable orcloud-based data systems
• Experience supporting customer-facing reporting or performance validation
• Understanding of how data can support product development and commercial decision-making

Role & Responsibilities

AsPerformance Engineer, you will own the flow of operational data from onboard systems through to engineering insight and customer reporting, helping to close the loop betweenreal-world operation andproduct development. Responsibilities will include:

• Owning the end-to-enddata andinsight pipeline across operational performance reporting
• Designing how data flows fromonboard systems into internal engineering tools and customer-facing outputs
• Building and maintainingdata pipelines, workflows, and reporting processes
• Developingdashboards and reporting tools to support internal teams and external stakeholders
• Translating complex operational datasets into clear conclusions and actionable recommendations
• Supporting engineering improvements,reliability decisions, and validatedfuel-saving claims
• Working closely withengineering,software, andcommercial teams to improve how data is structured, automated, and applied
• Continuously improving reporting accuracy, usability, and scalability as the fleet grows
• Helping to define how product performance is measured, understood, and communicated across the business

Why Join?

This is a rare opportunity to join a business developingreal-world clean technology for the global shipping market. You will benefit from:

• Working onreal climate-impact hardware
• High levels ofownership in a growing and ambitious business
• The opportunity to shape theproduct performance feedback loop at a defining stage of growth
• Broad exposure acrossengineering,data, software, andcommercial teams
