Job description

Job Details

New ideas are all around us, but only a few will change the world. That's our focus at JPL. We ask the biggest questions, then search the universe for answers-literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission-your opportunity-is to seek out the answers that bring us one step closer. If you're driven to discover, create, and inspire something that lasts a lifetime and beyond, you're ready for JPL.

Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence.

Responsibilities

The Cybersecurity Engineer position is within the Systems Security Engineering and Research team (6230) within the Office of the Chief Information Security Officer (6200).

We invite you to join our team as a Cybersecurity Engineer, contributing to the development of advanced security capabilities within missioncritical embedded platforms.

In this role, you will design and implement novel security mechanisms that safeguard network data flows within embedded systems supporting authentication and encryption applications. You will also assess how these mechanisms interact with and strengthen antitamper technologies.

This position requires conducting foundational research in embeddedsystem security, with focus areas that include authentication, encryption, system monitoring, and antitamper protection. Key responsibilities include:

  • Developing and integrating unique security mechanisms for embedded network data flows
  • Analyzing interactions among authentication, encryption, and antitamper technologies
  • Performing fundamental research in embeddedsystem security architectures and methods

Required qualifications:

  • Typically requires a bachelor's degree in Cybersecurity, Electrical Engineering, Computer Engineering, Computer Science, Applied Physics, or a related technical discipline with a minimum of 9 years of directly relevant cybersecurity engineering experience in mission-critical, embedded, aerospace, or high-performance computing environments; master's degree with 7 years of related experience or a PhD with 5 years of related experience.
  • Demonstrated expertise in cybersecurity engineering for complex hardware and software systems, including FPGA-based architectures, embedded systems, and high-performance data processing environments.
  • FPGA architecture development and low-level FPGA implementation techniques, including manual placement and routing, timing closure, floor planning, resource optimization, and hardware performance analysis.
  • High-speed networking and transport architectures for FPGA and accelerator-based systems, including low-latency and high-bandwidth interfaces, distributed compute fabrics, and deterministic networking.
  • Data science methodologies, large-scale telemetry and sensor data analysis, statistical analysis, and algorithm development for mission, scientific, or cybersecurity applications.
  • Embedded system security, hardware security, anti-tamper technologies, hardware assurance, or applied vulnerability research.
  • This position requires the candidate to be eligible for a Top-Secret clearance.

Preferredqualifications:

  • Experience with advanced FPGA platforms and heterogeneous compute architectures, including AMD/Xilinx, Intel/Altera, Microchip, Lattice, or radiation-tolerant FPGA technologies.
  • Experience with custom hardware development, embedded Linux environments, accelerator-based computing, real-time distributed systems, or high-reliability embedded architectures.
  • Significant experience handling, processing, and analyzing large volumes of mission, sensor, telemetry, or cybersecurity-relevant data within distributed, accelerated, or heterogeneous computing environments.
  • High-performance computing (HPC) architectures and clustered compute systems for large-scale data processing, telemetry processing, and accelerated analytics workloads.
  • Strong understanding of networking concepts and architectures supporting high-performance FPGA systems, including high-speed serial interfaces, secure data transport, distributed processing systems, and low-latency communications.
  • Experience translating cybersecurity, mission assurance, and operational requirements into technical architectures spanning hardware, firmware, software, networking, and distributed compute systems.
