Complex Systems Engineer information

What does a complex systems engineer do?

A Complex Systems Engineer designs, analyzes, and manages intricate systems that involve many interdependent components, such as in aerospace, transportation, or large-scale software systems. They use systems thinking and modeling techniques to ensure all parts of a project work together efficiently and reliably. Their work often involves collaborating with experts from multiple disciplines to address technical challenges and optimize overall system performance. Complex Systems Engineers play a vital role in projects where integration, scalability, and adaptability are crucial for success.

What are the key skills and qualifications needed to thrive as a complex systems engineer?

To thrive as a Complex Systems Engineer, you need a strong foundation in systems engineering principles, modeling and simulation, and a relevant engineering degree. Familiarity with tools such as MATLAB, SysML, Model-Based Systems Engineering (MBSE) platforms, and industry certifications like INCOSE CSEP are typically required. Exceptional problem-solving, collaboration, and communication skills set standout professionals apart in this field. These abilities are crucial for designing, integrating, and managing intricate systems to ensure functionality, reliability, and successful project outcomes.

How does a complex systems engineer typically collaborate with multidisciplinary teams during a project?

Complex Systems Engineers often work closely with professionals from various disciplines, including software developers, hardware engineers, project managers, and domain specialists. Their role is to ensure that all components of a system integrate seamlessly, which requires frequent communication, joint problem-solving sessions, and coordinating design reviews. Effective collaboration is crucial for identifying potential integration issues early and ensuring that the overall system meets both technical and user requirements. This multidisciplinary teamwork not only enhances project outcomes but also provides opportunities for skill development and broader industry knowledge.

What is the difference between Complex Systems Engineer vs Systems Engineer?

AspectComplex Systems EngineerSystems Engineer
Required CredentialsBachelor's or higher in engineering, systems science, or related fields; certifications like INCOSE CSEPBachelor's degree in engineering, computer science, or related fields; certifications like Cisco CCNA or CompTIA
Work EnvironmentDesigning, analyzing, and integrating complex systems across industries like aerospace, defense, and technologyDeveloping, testing, and maintaining systems in IT, software, or hardware sectors
Employer & Industry UsageUsed by organizations managing large-scale, interdisciplinary projects requiring system integrationCommon in IT, software development, and hardware manufacturing companies

While both roles involve system design and analysis, Complex Systems Engineers focus on large, interdisciplinary systems with high complexity, whereas Systems Engineers typically work on specific subsystems or software/hardware components. The roles often overlap but differ mainly in scope and complexity.

About the Role

We are seeking a Senior FDIR-FSW Systems Engineer to support the design, analysis, and verification of Fault Detection, Isolation, and Recovery (FDIR) systems for advanced LEO and MEO satellite programs. In this role, you will work closely with multidisciplinary engineering teams to develop robust fault management strategies, analyze satellite systems and subsystems, and ensure flight software reliability through verification, validation, and testing. The ideal candidate has extensive experience with satellite flight software, systems engineering, and FDIR methodologies within mission-critical aerospace environments.

Key Responsibilities
  • Design and analyze Fault Detection, Isolation, and Recovery (FDIR) strategies for satellite systems.
  • Perform systems engineering analysis for satellite platforms and subsystems.
  • Conduct failure analysis using FMECA and Fault Tree Analysis (FTA) methodologies.
  • Evaluate how failures propagate across system and subsystem levels.
  • Develop fault management strategies by tracing failures from system-level to unit-level components.
  • Support the design, verification, validation, and testing of satellite flight software (FSW) for FDIR.
  • Collaborate with cross-functional engineering teams to ensure system reliability and mission success.
  • Contribute to system integration, testing, and operational readiness activities.
  • Apply industry standards and best practices for FDIR development and verification.
Required Qualifications
  • Bachelor's degree in Electrical Engineering, Computer Science, or a related engineering discipline.
  • 10+ years of relevant engineering experience (advanced degrees may be considered in lieu of some experience).
  • Experience supporting LEO and/or MEO satellite systems.
  • Strong cross-functional collaboration and systems engineering experience.
  • Experience analyzing satellite systems and subsystems.
  • Familiarity with Failure Modes, Effects, and Criticality Analysis (FMECA) and/or Fault Tree Analysis (FTA).
  • Strong understanding of failure propagation across complex systems.
  • Ability to decompose system-level failures to the unit level and evaluate their overall system impact.
  • Knowledge of satellite Flight Software (FSW) and FDIR monitoring concepts.
  • Experience testing hardware and software components supporting FDIR functionality.
Preferred Qualifications
  • Experience with ECSS-E-ST-70-41C standards.
  • Experience with PUS-based FDIR verification, validation, and testing.
  • Experience supporting satellite flight software development and mission assurance.
  • Familiarity with ESA standards and aerospace systems engineering best practices.
