Satellite Propulsion Engineer

Take end-to-end ownership of a flight product and help bring water-based satellite propulsion technology from customer order to final delivery.

Ascend Beyond Space is a small, agile New Space startup located near the Annecy lake, in the heart of the French Alps. We develop state-of-the art subsystems for satellite missions and end-of-life disposal, with the ambition of making space more sustainable.

02 // ROLE

About the role

The Propulsion Department develops multiple types of satellite propulsion and atittude control devices and subsystems, including water resistojet-based propulsion system, cold-gas thrusters, propulsion control electronics and other critical components for satellites. As Satellite Propulsion Engineer, you will take end-to-end responsibility for some of Ascend Beyond Space's propulsion subsystems such as the Ascend propulsion system.

You will work closely with AIT engineers, suppliers, manufacturing partners and customers across original design, technical outreach, manufacturing coordination, assembly, testing, product documentation, final delivery and continuous improvement.

03 // RESPONSIBILITIES

What you’ll do

As Satellite Propulsion Engineer, you will become the owner of our Ascend propulsion system, a state-of-the-art high reliability resisto-jet propulsion and deorbiting system. You'll be the reference person for the product across its whole lifecycle: original design of new configurations, answering customers' technical questions, support built and testing of flight units, and delivering them. You'll run it day to day, make decisions about it, and keep improving it.In practice, you will:

Be the technical point of contact for customers and the sales team, from first enquiry to after-delivery support.

Plan and coordinate production with suppliers and manufacturing partners, so every order ships on time.

Support design, assembly and testing of flight units hands-on, including coordinating vibration, shock and radiation campaigns as well as documenting, reviewing or improving procedures and processes for it.

Guarantee quality and performance, working with our AIT engineers to meet space qualification standards.

Keep the Ascend propulsion system improving by feeding what you learn from customers, missions and testing back into the product, its processes and its documentation.

You'll work closely with AIT engineers, suppliers, manufacturing partners and customers, and you'll be the one who makes sure the Ascend propulsion system delivers on its promise.

Room to grow: once you've gotten hold of Ascend, the role can expand, depending on your interests. That could mean managing other Ascend Beyond Space products, or moving into detailed design and analysis of our next satellite subsystems.

• 01 — Provide technical support for sales activities and customers around Ascend and other propulsion products.
• 02 — Plan and coordinate the design, manufacturing and testing from customer order through qualification and delivery.
• 03 — Take an active, hands-on role in the design, manufacturing and assembly of Ascend units.
• 04 — Work with AIT engineers on quality standards, space qualification and test campaigns.
• 05 — Based on interest, design and develop the next Ascend Beyond Space satellite subsystems

04 // PROFILE

What we’re looking for

Previous hands-on experience with usage, testing, or qualification of propulsion systems.

Profficiency in mechanical CAD design and FEA.

Hands-on, proactive, and quality-focused mindset, with strong attention to detail.

Ability to take ownership of technical activities, plan and execute them independently, deliver on time and to a high standard of quality.

Comfortable collaborating with engineering, manufacturing, suppliers, and customers.

Adaptable and effective in a fast-paced technical, product development, or engineering environment.

Experience with resistojet technology

Knowledge in refractory materials and high temperature heaters

Experience with ECSS and/or NASA-STD/HDBK
