Career ladder

From Junior to Principal

A typical UK progression for propulsion engineers. Years are guidance — strong people move faster, and many senior folks sidestep into research, product or management.

  1. Level 1

    Junior Propulsion Engineer

    0–2 yrs

    Assists in the design and testing of propulsion systems under the guidance of senior engineers.

  2. Level 2

    Propulsion Engineer

    2–5 yrs

    Takes ownership of specific propulsion system components and leads small-scale testing and analysis.

  3. Level 3

    Senior Propulsion Engineer

    5–10 yrs

    Leads the design and development of complex propulsion systems, manages project teams, and ensures compliance with industry standards.

  4. Level 4

    Principal Propulsion Engineer

    10+ yrs

    Oversees the entire propulsion system development process, provides strategic direction, and mentors junior engineers.
