Controls Engineer

Summary: The APL Space Exploration Sector (SES) is developing complex avionics systems for a number of unmanned planetary, heliophysics and national security missions that include feedback controllers. Control systems under development support spacecraft navigation, thermal management and power conversion. APL/SES is seeking a Controls Engineer to lead development of analog and digital controllers with pump, motor or power conversion plants. The candidate will work closely with spacecraft systems engineers to integrate feedback controllers into spacecraft electrical systems. The candidate will be a member of a dynamic integrated product team and support all phases of product development, from early architecture through detailed implementation to integration and test (I&T) and flight support.

•Lead the design, modeling and analysis of controller circuits for avionics applications, including spacecraft navigation, thermal management and power conversion.
•Establish, allocate, and budget gain/phase margins for performance stability.
•Support the design of electrical interfaces between avionics and payloads.
•Coordinate activities with avionics hardware development team including electronic design engineers, software, packaging, test engineers, and manufacturing personnel.
•Generate avionics subsystem documentation, including requirements, interface control documents and test procedures.
•Present at program level design reviews. Participate in proposal activities. Mentor staff to expand the group competence in controls.
•Participate in internal professional service (e.g. committees) and external professional service (e.g. technical conferences).

Required Qualifications:

  • M.S. in Electrical Engineering, Aerospace Engineering, or related discipline.
