ROLE: SR. SPACE SYSTEMS STRUCTURAL ENGINEER
LOCATION: Bothell, WA

Portal Space Systems services a diverse range of customers and is looking for exemplary individuals capable of supporting our missions.

As a Senior Space Systems Structural Engineer, you will play a pivotal role in ensuring our spacecraft systems' structural integrity and performance. Working closely with cross-disciplinary teams, you will lead advanced structural analysis, design optimization, and testing initiatives to meet mission-specific requirements. This role demands technical expertise, collaboration, and a proactive approach to delivering innovative and reliable solutions for space missions.

RESPONSIBILITIES

• Perform advanced structural analysis for spacecraft, including modeling, simulations, and verification of components under various loading conditions such as transportation, ground testing, launch, in-orbit, and re-entry scenarios.
• Conduct Finite Element Analysis (FEA) simulations using industry-standard software (e.g., ANSYS, NASTRAN, Abaqus) to evaluate stress, strain, thermal response, vibration modes, and structural fatigue of spacecraft, subsystems and components.
• Collaborate with design engineers to optimize structural components for weight, strength, and cost. Provide feedback on material selection, design iterations, manufacturability and testing.
• Assess the structural integrity of spacecraft, identifying potential failure modes, and conducting risk assessments. Ensure compliance with spaceflight standards and mission requirements.
• Analyze spacecraft performance during various mission phases and propose structural solutions to meet mission-specific requirements (e.g., high G-force during launch, microgravity conditions in orbit, and exposure to thermal extremes).
• Support the design and execution of structural testing programs, including static load testing, vibration and acoustic testing, and thermal and thermal-vacuum cycling. Interpret test data, correlate and update models as necessary.
• Prepare detailed analysis reports, including simulation results, methodologies, and recommendations. Communicate technical findings to cross-functional teams and external stakeholders.
• Work closely with other engineering disciplines, such as systems engineering, propulsion, thermal, avionics, and materials engineering, to ensure integrated and optimized spacecraft designs.
• Guide junior engineers and interns in best practices for structural analysis, providing mentorship and technical expertise to the team.

BASIC QUALIFICATIONS

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or related field with a focus on structural mechanics.
• 5-10 Years of experience in structural analysis and modeling, specifically in the space industry.
• Proficiency in FEA tools such as ANSYS, NASTRAN, or Abaqus.
• Extensive experience with spacecraft structural design and analysis, including materials used in space applications (e.g., composites, titanium, aluminum alloys).
• Strong understanding of structural dynamics, stress analysis, and fatigue techniques.
• Knowledge of spacecraft structural design requirements and environmental conditions (thermal, vibration, acoustic loads).
• Successful demonstration of spacecraft designs that have met mission objectives.
• Ability to interpret and apply aerospace industry standards (e.g., NASA, ESA, MIL-STD).
• Excellent written and verbal communication skills.

PREFERRED SKILLS AND EXPERIENCE

• Advanced degree (Master’s or PhD) in a relevant engineering discipline.
  
• Hands-on experience with the design, analysis, and testing of spacecraft or satellite systems.
  
• Proficiency with CAD tools (e.g., NX, CATIA, SolidWorks) is a plus.
  
• Familiarity with regulatory guidelines and industry standards (e.g., NASA, SMC, MIL-STD).
  
• Experience in vibration analysis, thermal analysis, and fracture mechanics.
  
• Proven ability to thrive in collaborative, multi-disciplinary teams.
  
• Adaptability to fast-paced environments with shifting priorities and deadlines.
  
• Passion for advancing the commercial space industry.
