[Nyx Earth] Propulsion Design Office Principal

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

Team Leadership & Engineering Management

Lead, mentor, and grow a team of engineers spanning thermal, structural/mechanical, CFD and CAD/design functions, fostering a culture of technical excellence and accountability.

Define individual scopes of work, set priorities, and manage workload across concurrent design activities to keep the team aligned with program milestones.

Conduct regular design reviews and one-on-ones, providing clear technical direction and supporting career development within the office.

Propulsion System Design & Technical Ownership

Making or approving key design decisions on feed or pressure systems, and associated structures.

Drive design-to-requirements traceability, ensuring system satisfy mass, thermal, and safety margins up to qualification.

Coordinate with Systems Engineering and Vehicle Design to manage interfaces between the propulsion system and adjacent vehicle subsystems.

Thermal Analysis & Management

Oversee steady-state and transient thermal analyses of propulsion components, ensuring compliance with temperature limits across all mission phases (ground operations, in-orbit, re-entry).

Review and approve thermal models, ensuring analytical rigor and correlation with test data.

Guide the team in identifying test platforms and defining test objectives.

Structural & Mechanical Design

Direct the mechanical design of propulsion structures, and brackets, ensuring adequate strength, stiffness, and fatigue life under load cases.

Oversee FEA and hand-analysis efforts to verify structural margins, and lead disposition of any margin concerns or design anomalies.

Working closely with AIT team to define and validate integration sequences.

CAD, Documentation & Configuration Control

Define and enforce CAD standards, model maturity gates, and drawing release processes within the design office, ensuring consistency and traceability across the propulsion product tree.

Oversee the maintenance of the engineering master model and associated bill of materials (BOM), coordinating with PDM/PLM administrators to keep configuration control current.

Ensure design documentation - including ICDs, engineering drawings, design notes, and specification trees - is complete, reviewed, and baselined on schedule.

Key Responsibilities

Location

You will perform your duties principally at the Company's premises in Bordeaux and may be required to travel from time to time to our company’s premises in Munich in the course of your duties.

What we would love to see from you

5+ years of hands-on experience in propulsion system design for launch vehicles, spacecraft, or space capsules, with direct exposure to liquid propulsion architectures.

Demonstrated ability to work across thermal, structural, and mechanical domains - you don't need to be the deepest expert in every field, but you can lead and critically review work across all three.

A track record of managing small-to-mid-size engineering teams in a fast-paced, hardware-delivery environment, with the ability to develop junior engineers while maintaining technical standards.

Prior experience running or closely supervising thermal (e.g. Thermal Desktop, ANSYS or equivalent) and structural analyses (e.g. NASTRAN or equivalent), and strong familiarity with CAD environments (CATIA, NX, or equivalent).

Experience managing complex system-level trades and interfaces and formal design review processes
