Space Flight Dynamics Engineer

Website germany_cs DER/PLC/20/31

Deadline to apply: 1st October 2020

How to apply: or here

The key person will join our on-site Flight Dynamics team supporting on a daily basis our customer ESA/ESOC.

The ESOC Flight Dynamics division provides mission analysis and flight dynamics operations support to ESA and third party missions during all mission phases. Flight Dynamics cooperates with different elements of the ground segment, such as the flight control teams, ground operations teams, science teams, the projects teams and the spacecraft manufacturers.

More specifically, the selected key person will primarily support the “EXOMARS RSP-JUICE EUCLID” program. This support may also included activities related to GAIA, Bepi Colombo, Mars Express, ExoMars TGO, Hera.

Tasks & Responsabilities

The key person will join a team responsible of the following tasks (not limited to):

  • Interplanetary command generation
  • Test & Validation Attitude for interplanetary missions.
  • AOCS command generation
  • AOCS and optical sensors calibration
  • Attitude determination and on-board systems monitoring and verification
  • Studies and mission analysis


  • Pre-launch development and testing
  • Support during critical mission phases (e.g. LEOP)
  • Product generation during routine mission phases
  • Maintenance and evolution of the flight dynamics system.


Mandatory skills:

  • University degree in a relevant engineering field, astronomy, mathematics or physics
  • Very good skills in linear algebra, in particular for problem solving related to geometry in the Euclidean 3–dimensional space.
  • Being familiar with different representations of rotation in 3D, thus including the representation of S/C attitude (cosine direction matrix, Euler symmetric parameters/ quaternions, Euler-angles …) is an asset.
  • Very good skills in calculus in one or several variables.
  • Skills in numerical methods for:
    • equations solving,
    • integration of differential equations,
    • function approximation and interpolation,
    • optimisation,
    • linear algebra problems.
  • Very good skills in classical mechanics, including:
    • kinematics and dynamics of point masses,
    • dynamics of rigid bodies,
    • dynamics expressed in non-inertial reference frames, e.g. including dynamics in rotating frames, rotation dynamics expressed in body fixed frame,
    • conservation laws in mechanics,
    • gravitational forces and field,
    • orbit dynamics, keplerian orbits and Kepler laws.
  • Ability to solve mechanics problems via analytical mechanics methods (e.g. lagrangian formulation) is a valuable asset.
  • Skills to apply their knowledge to develop solutions to technical (mathematical and dynamical) problems in cooperation with customers and other experts
  • Ability to define, implement, validate and operate software which applies the above solutions (using e.g. Unix and/or Linux scripting languages, Fortran 77 and/or 95, C++)
  • Will to take operational responsibility in multi-discipline teams
  • Fluency in English, both in speech and writing
  • Coordinate and interact with other service providers in operations and other fields.
  • Ability to work independently

Additional skills (which will be considered as an advantage):

  • Familiarity with the ESOC environment
  • Familiarity/experience with Flight Dynamics operations engineering tasks
  • Experience dealing with external interfaces
  • Experience with Linux, network services and protocols, and system administration
  • The ability to multi-task efficiently; working on multiple activities, multiple subsystems and if applicable multiple missions simultaneously.
