Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Perform preliminary design and comparative analysis of turbomachine power cycles and architectures for rocket engines. Collaborate with multidisciplinary teams to define performance budgets, manage technical risks, and validate models using test data.
Requires a Master's degree in aerospace or equivalent with at least two years of experience in turbomachinery design. Proficiency in 0D/1D flow analysis, rotor dynamics, and professional English is essential.
By joining Alpha Impulsion as a Turbomachinery system engineer in the Toulouse office, you will play a key role in the development of propellant feed systems for multiple iterations of our autophage rocket engines.
Reporting to the Technical Lead, you will be responsible for performing preliminary design of turbomachine power cycles for AMBER (current demonstrator) and GARNET (full-scale cryogenic launcher). This includes architecture trade studies of power generation for autophage fuselage insertion and oxidiser pressurisation, comparing designs of gas turbines and electromechanical solutions. You will then contribute to demonstrating the high performance of autophage propulsion, especially through testing.
Alpha Impulsion is finalising the development of a small-scale engine for AMBER as part of a major French national contract. Its goal is to derisk at small scale technologies to be used in systems for defence and in-space applications.You will embark on a young project, with the opportunity to build it from start to qualification and exploitation.
As part of your missions, you will be entrusted with the following responsibilities:
Perform comparative analysis of turbine and power transmission architectures, performance management by the definition of a multiphysics and empirical performance model, spanning a range of sizes, propellants and materials depending on the application and size of your autophage engines.
Collaborate with the system engineering team, integrating your work within a model-based system engineering logic with other engineering teams (systems, materials, mechanics, propulsion) in both offices (FR and IT).
Define and manage performance budgets and perform mass impact studies in collaboration with other teams.
Analyse technical risks: thermal and corrosive environments, destructive transients, gyroscopic interactions, lubrication difficulties, flight loads, etc. Take part in the development plan and testing methods.
Anchor the performance model using test data from the current prototype and validate turbine preliminary sizing.
Expand your work to turbines, pumps, gas generators, diffusers, injection, propellant management, and contribute in building the full engine cycle.
Master's degree in aerospace or equivalent.
Two years of experiences on turbomachinery design or similar project. Professional culture of turbomachinery for aerospace, design and manufacturing methods.
Systems engineering methods, familiarity with MBSE appreciated.
Applied knowledge of 0D / 1D flow line analyses and performance analyses, including bladed rotors. Ability to estimate the dynamic response of flow components and evaluate off-design performance.
Proficiency with EcoSimPro ESPSS or equivalent appreciated.
Applied knowledge of rotor dynamics and dynamic sealing methods.
Knowledge of turbomachinery testing methods.
Ability to report in traceable technical documentation.
Affinity with project management and Agile frameworks.
Professional English required. Italian/French appreciated.
Base salary negotiable based on experience. Additionally, competitive compensation package including meal vouchers, holidays vouchers, 75% public transport reimbursement (versus the usual 50%), sustainable mobility package “Forfait Mobilité Durable”, IT material compensation, team performance bonus. Flexible remote work organisation.
If you thrive on challenge, take on a new one and join the crew.
Alpha Impulsion is pioneering the autophage rocket engine to propel the next generation of light launchers. By using the fuel as the rocket’s structure, we eliminate the need for fuel tanks, multiple stages, and other heavy components that don’t contribute to propulsion. Based in France and Italy, we aim at building the most cost-efficient European launcher for small satellites by 2028 🚀 We are proud to be trusted by numerous European partners, including CNES, ESA BIC Sud France & Turin, the Takeoff accelerator & Bpifrance.
