Quick facts about Spaceium: Spaceium(YC S24) ) is building space stations to refuel and repair other spacecraft • YC S24, one of the largest seed round of the cohort • Demo space mission flying soon • Millions of dollars in contract • People talk about thinking outside of the box… there is no box at Spaceium. We are working on things that haven’t been done before. • Founders have known each other for 6 years

Note: we're in hustle mode. working late, building something huge. this isn't a place to cruise 9-5. we're looking for people who want to build something generational.

If you are crazy enough that you think you could change the world, this is the place for you.

At Spaceium, we’re redefining space exploration by developing cutting-edge systems that power our stations. As a Mechanical Engineer – Fluid Storage and Transfer Systems, you’ll be at the forefront of designing and optimizing fluid systems for space applications. Your role will focus on sourcing critical components and designing custom parts to enable reliable storage and transfer of fluids in challenging space environments. Collaboration with multidisciplinary teams will be vital, and a solid understanding of fluid dynamics, thermodynamics, and mechanical design is essential.

Responsibilities

• Design and develop systems for fluid storage and transfer in space, ensuring high performance and reliability.
• Design, source, and evaluate components such as tanks, valves, regulators, pumps, and tubing for fluid systems.
• Design custom mechanical components to meet the unique requirements of space-based fluid operations.
• Conduct flow, pressure, and thermal analyses to optimize system functionality in microgravity and vacuum conditions.
• Collaborate with structural, avionics, and systems engineers to integrate fluid systems seamlessly into spacecraft designs.
• Perform rigorous testing and validation of fluid systems to ensure they meet mission-critical standards.
• Maintain comprehensive documentation, including design specifications, test plans, and operational protocols.
• Adhere to aerospace industry standards and implement best practices for high-reliability fluid systems.

Basic Qualifications

• Bachelor’s degree in Mechanical Engineering or a related field.
• 2+ years of experience designing fluid systems or similar mechanical systems.
• Strong understanding of fluid mechanics, thermodynamics, and system design principles.
• Experience sourcing components and working with vendors to meet engineering specifications.
• Proficiency with CAD tools such as SolidWorks, CATIA, or AutoCAD for component and system design.

We’re working on innovative technologies that have never been developed before, so direct experience isn’t always necessary. If you’re eager to learn, ready to take on ambitious challenges, and passionate about space exploration, we encourage you to apply. Whether you’re new to the field or have extensive expertise, we value your creativity and dedication to solving tough problems.

Preferred Skills and Experience

• Passion for spaceflight and high-reliability electronic systems with familiarity in aerospace design practices.
• Self-starter with experience delivering hardware under demanding time and resource constraints.
• Creative problem solver with strong first-principle fundamentals, capable of assessing risk and making design decisions with limited data.
• Experience in a nimble, technical engineering role, with a scrappy, entrepreneurial approach to meeting tight time or budget constraints.
• Hands-on experience with testing and troubleshooting fluid storage and transfer systems under demanding conditions.
• Familiarity with aerospace standards, materials, and operational constraints in space.
• Proficiency in simulation and analysis tools such as ANSYS, MATLAB, or similar.
• Self-starter with strong first-principles thinking and a scrappy, entrepreneurial mindset.
• Excellent communication skills, with attention to detail and a commitment to quality.

Additional Requirement

• Extended hours and weekend work may be required to support critical project and mission milestones.

Compensation:

• Pay range: $90k-$110k USD per year
• Equity range: 0.1% - 1%
