to join their growing team within the space sector.

Location:

Madrid, Spain

Salary:

€30,000 - €40,000 per annum

Working pattern:

Full-time

Working environment:

Hybrid

Working Language:

This organisation is developing

advanced propulsion systems

for space applications and is looking for a

hands-on engineer

to take ownership of a

critical fluidics subsystem.

This role focuses on precision engineering in challenging environments, working with liquid propellants and vacuum systems to support real spaceflight applications.

The role will involve:

Owning the development of a propellant management subsystem,

driving it from design refinement through to production readiness

Leading mechanical and functional improvements,

with a focus on

reliability and scalability

Designing and qualifying in-vacuum propellant filling processes,

including

contamination control

and

calibration procedures

Characterising system performance,

including flow delivery, pressure stability, gas behaviour and fill accuracy

Creating and maintaining detailed

test procedures, assembly documentation and qualification reports

Collaborating closely with propulsion, electronics and testing teams

during integration and validation campaigns

Supporting supplier engagement

and contributing to make-vs-buy decisions





Contributing to vacuum chamber redesign

and

development activities

Key requirements:

Background in

vacuum systems, precision fluidics, analytical instrumentation, or a related engineering discipline

(industry or research)2-4 years hands-on engineering experience,

ideally in a lab, R&D; or production environment

Experience working with

sensitive or reactive liquids (e.G. hygroscopic, conductive, or corrosive fluids) Familiarity with

vacuum systems,

including pumping equipment, low-pressure measurement, leak detection and outgassing behaviour

Experience

designing or assembling sealed mechanical systems

(e.G. fittings, seals, polymer-to-metal interfaces) Broad engineering fundamentals with a

solid understanding of physics principles

Comfortable working in a small, fast-moving team with evolving responsibilities

Experience with

mechanical CAD tools (e.G. Fusion 360, SolidWorks or similar) Exposure to areas such as

ionic liquids, electrochemical systems, or space environmental standards

(e.G. thermal vacuum, outgassing) is desirable

Familiarity with

pressure systems, pneumatic testing, microfluidics, MEMS, or similar technologies

This is a

highly practical, hands-on role

offering the opportunity to take real ownership of a critical subsystem and directly influence the development of

next-generation propulsion technology.
