Job Description

Location: El Segundo California Security Clearance: TS/SCI - Current Job Description:

The Responsive Space Systems Department is seeking cleared (in scope SSBI preferred) Space Mission Systems Engineers who bring space mission system leadership, engineering, capture, and/or proposal experience to a growth oriented organization. Prior experience in satellite operations and/or orbital analysis is desired, yet not required. This role will leverage your knowledge of all elements of the space mission design process including initial concept development, system-level trades, requirements definition, mission geometry, orbit selection, mission timeline, performance assessment, mission utility, and mission level cost optimization. The job responsibilities may include constellation and sensor MBSE. Knowledge of Space, Ground, Programmatics, and Launch segment inter-relationships to support the optimization of a mission baseline is desired.

The candidate must have the ability to manage and evaluate technical solutions for the development of complex space missions based on customer requirements. The work performed will help inform the design and development of EO/IR payloads for sensing missions in the military, civil, and commercial domains. One aspect of the position will be astrodynamics assessments of the mission of interest to include coordinate systems definition, orbital maneuvers/transfers, orbit determination, Kalman filtering, perturbation techniques, atmospheric models, and analysis of specialized orbits. Other potential responsibilities include supporting the design and assessment of individual elements of a space mission, including spacecraft bus subsystem design, launch system selection, ground segment, user segment, mission operations, and cost modeling.

The candidate should be capable of leading efforts that use tools such as STK, HPOP, Matlab, C++, or similar that create analytical products and perform model generation for data analysis and performance prediction. Possible tasks include defining day in the life (DITL) CONOPS for space mission systems. This position will interface with (or serve in the role of) Capture Manager, Proposal Manager, Lead Systems Engineer and other stake holders to ensure program objectives are achieved. Successful candidates should expect to be immersed in a fast-paced, team-based, and challenging technical environment where an individual with talent and initiative can stand out and thrive.

Required Skills:
  • Minimum 10 years engineering experience with at least 4 years working space systems engineering
  • Evidence of problem solving and time management skills
  • Experience working with multi-disciplined teams
  • Excellent presentation skills and negotiation skills; VP or G.O. level briefing experience preferred
  • Experience writing proposals to government or commercial entities
  • Experience defining the elements of a space mission, performing preliminary mission design, and developing operational concepts
  • Experience generating systems engineering products to architect a conceptual mission architecture
  • Experience with orbit selection, design, and ability to conduct orbit tradeoffs
  • Experience quantifying mission utility and analyzing figures of merit
  • Experience with mission geometry, relative satellite motion, and analyzing viewing and lighting conditions
  • Experience with targeting, ground station pass analysis, constellation design, stationkeeping analysis, or collision avoidance
  • U.S. Citizenship
  • Ability to access to US only data systems
  • U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.
  • In scope SSBI with recent TS/SCI work experience
Desired Skills:
  • Ability to establish and maintain strong working relationships with all levels of the organization
  • Ability to work independently, determine and develop approach to solutions
  • Government or military program office or laboratory experience
  • Leadership skills to develop proposals for Government, commercial, and international customers
  • Experience in Model Based system Engineering tools (such as IBM Rational or Vitec CORE) for developing architectures and functional analysis.
  • Familiarity with SEIT tools such as STK-HPOP, MATLAB, C++, Python, and Pivot Tables
  • Familiarity with Earth, target, and regional coverage; producing access reports and performing Monte Carlo analysis of constellations with sensor physics in the loop
  • Experience modeling different types of spacecraft propulsion (e.g., chemical or electric/low thrust)
  • Experience defining technical budgets (Delta V budget, Link budget, Mass budget, Power budget, Propellant budget, Payload budget) and Orbit Cost Function
  • Experience with spacecraft bus design and ability to carry out first order design of spacecraft subsystems
  • Experience with small satellite design
  • Familiarity with the Responsive Space concept and methods for reducing space mission cost, and familiarity with space mission cost models including USCM8, SSCM, NICM, and COCOMO 81
  • Experience with mission operations and CONOPS
  • Experience designing interplanetary trajectories (2-body and n-body problems)
  • Knowledge of spherical trigonometry
  • Knowledge of space radiation environment and orbital debris environment
  • Knowledge of end-of-life and disposal approaches
  • Experience with EO/IR payload design
  • Ability to perform launch system selection and identification of launch opportunities
  • Knowledge of ground segment, antenna services, and data distribution
  • Knowledge of US Export/Import law in regards to space technologies

Required Education: Bachelor’s of Science (B.S.) degree in Engineering, Physics, Math, Aerospace, Computer Science or related discipline.

Desired Education: Advanced degree in Engineering, Physics, Math, Aerospace, Computer Science, or related discipline.

This position requires a U.S. person or the ability to obtain an Export Authorization from the appropriate government agency for non-U.S. persons

U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.
