Fluid Systems Engineer

Fluid Systems Engineer

Location: France (Relocation Support Available)

Employment Type: Permanent

iO Associates are partnered with an innovative European space technology company developing next-generation launch systems. Due to continued growth, they are looking to add an experienced Fluid Systems Engineer to their engineering team. This is an opportunity to work on complex fluid and propulsion-related systems across both flight hardware and ground test infrastructure, contributing throughout the full engineering lifecycle from concept development through to testing, integration and launch operations.

The Opportunity

As a Fluid Systems Engineer, you will take ownership of critical fluid hardware and systems used across launch vehicle and ground\-support applications. Working within a multidisciplinary engineering environment, you will be involved in the design, analysis, integration and testing of fluid systems that support cutting-edge space missions.

This position offers a strong blend of design, analysis and hands-on engineering, making it particularly well suited to engineers who enjoy seeing their designs progress through to real-world testing and operation.

Key Responsibilities

• Design and develop fluid and mechanical systems for both flight and ground-support applications
• Take ownership of hardware throughout the full engineering lifecycle, from initial requirements through to testing and qualification
• Perform fluid, thermal and mechanical analyses to support system development
• Design piping layouts, fluid routing, mechanical assemblies and supporting hardware
• Select and specify valves, regulators, sensors, fittings and other fluid-system components
• Support modelling and simulation activities for fluid behaviour and system performance
• Define and support testing, commissioning and qualification activities
• Analyse test data, identify performance improvements and troubleshoot technical issues
• Support integration and operation of propulsion and fluid test facilities
• Work closely with manufacturing, suppliers, technicians and wider engineering teams
• Balance performance, reliability, manufacturability and programme requirements throughout development

About You

We are interested in speaking with engineers who have:

• A degree in Mechanical Engineering, Aerospace Engineering or a related discipline
• 5+ years of industry experience within space, aerospace, propulsion, automotive, energy or another highly regulated engineering environment
• Experience designing mechanical components and assemblies using CAD software
• A strong understanding of fluid mechanics and fluid-system design
• Knowledge of valves, regulators, pumps, sensors, fittings, pressure vessels and related fluid hardware
• Experience working across the full engineering design lifecycle
• Practical experience supporting the manufacture, assembly, integration and testing of engineered systems
• Strong problem-solving skills and a hands-on engineering mindset
• Excellent communication skills and the ability to work within multidisciplinary teams
• Experience with propulsion systems, cryogenic fluids, pressurised gas systems, test facilities or launch vehicle development would be highly advantageous

Please note: This role is not focused on CFD development. Candidates from Mechanical Design Engineering backgrounds with experience designing fluid systems and associated hardware are likely to be the strongest fit.

What's On Offer?

• Opportunity to work on genuinely cutting-edge spaceflight technology
• Significant technical ownership and responsibility
• Strong long-term career development opportunities
• Structured learning and development programmes
• Relocation support for candidates moving from elsewhere in Europe or internationally
• Collaborative and international engineering environment
• Competitive salary and benefits package

Relocation Support

For candidates relocating to France, dedicated relocation support is available through an external specialist partner.

Assistance can include:

• Accommodation search support
• Visa and residency guidance where required
• Administrative support during relocation
• Ongoing assistance throughout the onboarding process

If you're a Mechanical Design or Fluid Systems Engineer looking to work on some of Europe's most exciting space hardware programmes, I'd be keen to discuss the opportunity further.
