Who is Clément Goujon?
Clément Goujon is an independent systems engineering and MBSE consultant, founder of Goujon Systems, based in Cherbourg-en-Cotentin, France. INCOSE CSEP certified, he was system architect of a major European Space Agency programme at Thales Alenia Space (Argonaut) and contributed to the development of MBSE in the European space sector, through R&D studies with ESA, such as the ESA MBSE workshop papers on the System Factory for Space Systems (2021, 2022), and within Thales Alenia Space itself, where he led MBSE development for the Turin site. He teaches Space Systems Engineering and MBSE at Master’s level at Université Toulouse III, in the CSA (Computer Science for Aerospace) Master’s programme. Full background and sources on the About page.
What does Goujon Systems do, and for whom?
Three things: systems engineering consulting (requirements, architecture, trade-offs, system-level IVVQ, review preparation), MBSE deployment and governance (Capella/ARCADIA, Cameo/SysML, SysML v2) and proposal preparation (win themes, compliance, red-team review). Clients are space, aerospace and defence programs across Europe: primes and system integrators who need senior independent expertise for a critical phase or review, and space start-ups and scale-ups building their engineering foundations. Work is delivered to ISO/IEC/IEEE 15288 and ECSS.
Which space programmes has Clément Goujon worked on?
He was the architect of ESA’s Argonaut lunar lander at Thales Alenia Space, up to phase B2. He also led many phase 0/A/B studies: Moon Village (16 studies for the Italian Space Agency on a lunar-surface station), HEARTED (European Earth-reentry demonstration mission), LCNS (lunar communication and navigation constellation) and CLTV (cislunar logistics transfer vehicle), as well as telecom satellites and crewed habitats, among others. He has hands-on experience of applying systems engineering to complex systems, and his expertise is recognised across Europe in the field.
Is Goujon Systems a company or a one-person practice?
Goujon Systems is a French sole proprietorship (micro-entreprise), SIRET 798 831 541 00023, founded and run by Clément Goujon. Engagements are delivered personally: there is no bench, no junior substitution, and no account manager between you and the engineer doing the work. “Goujon Systems” is a trademark registered with the INPI.
What does INCOSE CSEP certification actually mean?
Certified Systems Engineering Professional is INCOSE’s mid-tier professional certification. It requires a knowledge examination based on the INCOSE Systems Engineering Handbook (5th edition, 2023), a minimum of five years of verified systems engineering experience, and professional references. It is a credential about demonstrated practice, not a training attendance certificate.
Which industries do you work in?
Primarily space, aerospace and defence: telecom satellites, lunar landers and transfer vehicles, crewed habitats, communication and navigation systems, and naval defence. The underlying methods transfer to any domain with long life cycles, safety or mission criticality, and a demanding institutional customer.
Do you take on training and lecturing engagements?
Yes. Clément teaches Space Systems Engineering and MBSE at Master’s level at Université Toulouse III - Paul Sabatier, and has delivered company-wide training and best-practice programmes inside a large space integrator.
Where are you based, and where do you work?
Based in Cherbourg-en-Cotentin, France. Work is delivered across Europe, remotely, on site for workshops when needed, in English, French and Italian.
How quickly do you reply?
Enquiries are answered personally, normally within one working day. There is no intake form, no qualification call with someone else, and no CRM sequence.
What should I include in a first message?
The program or product, the life-cycle phase you are in, the decision or review that is coming, and what is currently worrying you. That is enough to tell you whether the problem is one worth engaging outside help on.
Do you sign an NDA before we talk?
Yes, whenever the conversation needs it, routinely so for bid and proposal work. An NDA before a first call is entirely normal and never a problem.
Is there a telephone number?
No published one. Email (contact@goujon-systems.com) and the booking scheduler reach Clément directly and get a faster answer than a switchboard would. A number is exchanged once an engagement is under way, or on request in a first email.
Book a free intro call.
Thirty minutes, no commitment, in English, French or Italian. Tell me about the program and I will tell you honestly whether I am the right person for it.
