SLS Orion Trajectory Analyst, Entry Level; ES2

Overview

The Mission Analysis and Trajectory Design Engineer supports the development, integration, and testing of flight mechanics simulations for NASA’s SLS/ARTEMIS program, NASA’s HLS program, and other NASA projects. This role requires a well‑rounded background in flight dynamics modelling, programming, and high‑fidelity analyses to optimize and integrate inputs for the flight dynamics of the Artemis mission.

• Analyze launch vehicle and spacecraft dynamics, equations of motion, and trajectories to assess performance and support mission analysis.
• Model ascent and in‑space environments, errors, disturbances, GN&C algorithms, sensors, actuators, and mechanisms.
• Simulate and analyze nominal, contingency, and failure scenarios during ascent and in‑space flight.
• Develop algorithms and tools to analyze 3 DOF trajectories using Monte Carlo techniques.
• Perform studies and insight analysis for NASA’s Human Landing System (HLS) program.
• Execute or modify existing software/scripts in C, Python, and C++.

• A degree in Aerospace Engineering, Mechanical Engineering, Physics or related field from an ABET‑accredited institution is required.
• Typical experience:
  Master’s degree with at least 3 years of experience, or Bachelor’s degree with 0–5 years of experience.
• U.S. citizenship is required and candidates must have a STAR .
• Detail-oriented, able to work independently and collaboratively, with strong communication and interpersonal skills.
• Technical skills: MATLAB, Fortran, C++, 3 and 6 DOF dynamic modeling;
  Linux, Bash; experience with computational clusters/servers.
• Familiarity with GN&C product design, integration, and analysis; ability to configure and run 6‑DOF Monte Carlo simulations; familiarity with convex optimization.
• Required experience in Trajectory Design and/or mission analysis;
  Python programming;
  Copernicus experience; software and simulation integration or modeling & simulation experience.

• Dynamic modeling of 3 and 6 DOF single‑body systems; mission design and trajectory design analysis.
• Creating, editing, and debugging software written in C, Python, MATLAB, Fortran, and C++.
• Optimization and improvement of analysis tools and GN&C models.
• Collaborating with GN&C leads and other engineering disciplines.
• Supporting verification and validation of technical products; preparing technical reports and briefings.

• Office environment with the ability to communicate clearly and professionally (written and verbal).
• Ability to travel domestically within the USA (approximately 5%).
• Ability to work at a computer for long periods; sitting at a desk for extended periods (as needed).
• Access to NASA facilities and interaction with clients; use of stairs or elevators as required.
• Equipment: operate a personal computer, telephone, and standard office equipment.
• Normal work hours with potential minimal overtime to meet schedule milestones.
• Ability to work independently with minimal supervision; good judgment and decision‑making skills.
• Grooming and dress appropriate for the position and safety considerations.

• Compensation range or hourly rate provided as a good‑faith estimate; actual compensation may vary by factors including responsibilities, education, experience, and applicable agreements.
• Benefits include health, dental, and vision insurance; paid time off and holidays; retirement benefits (401(k) with matching); educational reimbursement; parental leave; employee stock purchase plan; tax‑saving options; disability and life insurance; pet insurance.
• Note:
