Orbit Fab's mission is to create the foundational infrastructure that will fuel a bustling in-space economy, capable of sustaining permanent jobs in space. Today, satellites cannot be refueled, which severely constrains their mobility and inhibits the development of economic activities in space. 

Orbit Fab breaks the single-use paradigm, pioneering our Gas Stations in Space™ refueling infrastructure and RAFTI™ technology to deliver propellant in space, enabling lower-cost satellite construction, increased maneuverability, precise control, and extended lifespans. The possibilities are unprecedented, opening the doors to unimagined operational strategies and business models. 

Since our establishment in 2018, we have already achieved the successful launch of three tankers to space. With offices in both the US and UK, we are working in close collaboration with partners and customers across the space industry. Orbit Fab is rapidly ramping up capabilities and requires exceptional talent to tackle important challenges. Our roles offer wide ranging opportunities to have a demonstrable impact and enable a bustling space economy.

About the Internship

Orbit Fab is developing an active refuelling interface called GRASP which acts as the key mechanism for delivering fuel to clients on orbit. This component would enable UK built (and potentially UK launched) fuel shuttle vehicles to perform in-space refuelling thus fulfilling this critical piece of space infrastructure technology.

To test GRASP in a representative environment, OFL seeks to model and perform 3DOF testing to mimic the dynamics of a docking scenario between incident spacecraft. The project to be undertaken will involve supporting the development of GRASP through such tests through a combination of the following and/or other skills to be developed through the course of this internship:

• Computer modelling of spacecraft docking interactions
• Validation of simulation results using previously gathered test data
• Development of ‘digital twin’ in MuJoCo, Isaac Sim or Gazebo for space mechanisms
• Data analysis of satellite docking interactions
• Contributing to the design and improvement of space mechanism products 
• Skills in technical documentation and report writing 

A successful applicant

• You should have built something, either software or hardware. We'd love it if that something has flown in space or been used by a customer! 

• You are currently pursuing a Bachelors, Masters, or PhD in a technical discipline especially in the skillsets listed above. 

• You have a demonstrated passion and capacity for hardware or software development, working in fast-paced environments and hands-on design and development from any maturity. 
• You share our appreciation for a diversity of thoughts, backgrounds and experiences, helping us all learn from each other and make smarter decisions. 
• You are a UK citizen or have the right to work in the UK. 

Minimum Requirements for the role

• Have experience with Python and/or C++
• Have experience with or ability to quickly learn one or more of the following software: Isaac Sim (preferred), MuJoCo,  Gazebo
• Available to be in person at Harwell, Oxfordshire, for a minimum of 3 days a week. 

• Ability to work well in an integrated collaborative team environment, including frequent interactions with external suppliers, other engineers, other interns, and managers. 

• Ability to work effectively in a dynamic professional setting with changing needs and requirements. 

Bonus Requirements:

• Have experience with git or other version control software’s such as SVN
• Have experience with docker or other containerization services
• Have experience with ROS2

The successful candidate will be paid the 2026 Real Living Wage, for a minimum 8 week placement with Orbit Fab

Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other marginalized people tend to only apply when they meet 100% of the qualifications. At Orbit Fab, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply if you feel you would succeed in the role above.

Location and Benefits

The UK Orbit Fab office is based at Harwell Campus, the UK’s preeminent gateway to the space industry, and only a short drive from Oxford with convenient access to London.

Eligibility

Candidate must have right to work in the UK.
