At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Raytheon brings the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. We deliver solutions that help our nation and allies defend freedoms and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense.

The Effector Guidance Electronics (EGE) department develops electronics for weapon system products. We engage at the outset of the weapon system development and follow our designs through deployment. Our products are deployed all over the world, from the ground to exoatmospheric environments and into space. We are responsible for the architecture, design, and documentation of deliverable FPGA embedded processing at Raytheon.

In this role as a Senior Principal FPGA Engineer, you will lead development of FPGA designs for all major vendors and device families including AMD/Xilinx, Altera, and Microchip. Designs commonly support the following applications: gigabit serial interfaces, Radio Frequency (RF) and Electro-Optical (EO) DSP, controls, data links, embedded processing, and processor interfaces. Designers collaborate with circuit card designers and systems engineers to develop requirements, architecture, modeling of algorithms, partitioning, code development, simulation, and place and route. Designs are verified against requirements using both directed test and constrained random methodologies. Design support is expected from requirements definition through production release. Design documentation and configuration management are required.

What You Will Do

Design and deliver production quality FPGA releases from initial proof of concept up to production Work cooperatively with systems, hardware, software engineers, and program management to ensure product success Lead FPGA-based systems architecture, and designs to include determination of parts, interfaces Design and code in VHDL for reliability, maintainability, reviewability and reusability Verify designs utilizing self-checking techniques with directed and constrained random tests, while tracking functional and code coverage Solve problems that are numerous and typically undefined where information is difficult to obtain Establish processes and operational plans for projects Create complete documentation including requirements, verification plan, user's guides and configuration management. Design support from requirements definition through integration and test Translate system level requirements into FPGA requirements Perform and participate in internal and external technical reviews Independently drive projects and execute to program schedules and budget May lead large integrated or cross product teams on moderate to large multi-year programs

Qualification

Typically requires a Bachelor's Degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 10 years prior relevant experience Experience architecting FPGA-based systems to determine parts, interfaces Minimum of 10 years of experience in at least 7 of the following categories: Digital Design and HDL coding targeting configurable logic devices Experience in delivering FPGA solutions to system level applications Experience in one or more brands of (Altera, Lattice, Microchip, AMD) FPGA devices and associated tools Experience with integration and debug of electronics using oscilloscopes, logic analyzers, multimeters, etc. Experience with FPGA timing constraints and timing closure Experience with digital simulation such as Questa, RivieraPro or similar tools Experience with industry standard interfaces and protocols such as AXI, PCIe, SPI, I2C, etc. Experience with Python or C programming Experience working with Intellectual Property (IP) Cores Qualifications We Prefer Radar processing techniques Image processing techniques for visual and infrared sensors Gigabit serial interfaces and multi-gigabit transceivers (MGTs) Experience with embedded processor and System on a Chip development for FPGA devices Knowledge of embedded systems design using Microblaze, Nios or ARM processors a strong plus FPGA design experience using a Linux-based development environment highly desired Knowledge of git and GitHub Knowledge of encryption/decryption standards such as AES, RSA, ECC, etc. Embedded systems design using ARM processors Verification utilizing hardware platforms System level FPGA requirements specification and architecture development Ability to identify links and potential impact on projects, programs, or systems Cross-discipline knowledge such as software, systems, modeling, etc. Highly motivated, high performers with a strong desire to learn and contribute in a fast-paced team environment Self-directed – Able to complete tasks with minimum oversight Practical knowledge of project management Familiarity with the Linux environment and commands Experience in a leadership role such as team lead, technical lead, project lead, etc. Proposal experience to include basis of estimate generation, resource identification, and constraint-based program schedule planning MS or Ph.D. in Electrical or Computer Engineering
