Firmware Engineer

Job Title: Sr. Firmware Engineer II - FPGA/VHDL (Remote)

Job Description

This role focuses on designing, implementing, and validating advanced FPGA-based firmware for space domain awareness and electro-optical/infrared (EO/IR) systems. You will collaborate closely with hardware and software teams to develop high-performance, reliable firmware that operates in challenging environments, including space. The position offers the opportunity to work with cutting-edge FPGA technologies, contribute to mission-critical space and ISR programs, and be part of a highly skilled team that values continuous learning and collaboration.

Responsibilities

• Collaborate with the hardware design team to define, refine, and document firmware requirements for FPGA-based systems.

• Complete FPGA logic design, coding, simulation, and verification using VHDL, ensuring robust and maintainable implementations.

• Perform synthesis, implementation, and timing analysis to meet performance, area, and power constraints on targeted FPGA platforms.

• Support hardware and software development teams during system bring-up, integration, and testing of new products.

• Provide subject-matter expertise on FPGA design methodologies, automated test development procedures, and best practices to internal teams and production support.

• Conduct research and analysis of customer specifications, datasheets, and technical manuals to determine design approaches, assess feasibility, and identify risks.

• Execute debugging and validation of FPGA designs in the lab, including root-cause analysis and resolution of complex issues.

• Develop and refine firmware architectures that support high-speed interfaces such as DDR4, Aurora, and multi-gigabit transceivers.

• Contribute to the development and optimization of FPGA-based image processing algorithms and related signal processing pipelines.

• Implement and verify software interfaces to firmware, including interrupts, DMA, and AXI-based communication paths.

• Participate in design and code reviews, providing constructive feedback and ensuring adherence to quality and reliability standards.

• Collaborate with cross-functional teams to support systems operating in radiation environments, including implementing and validating SEU/SEL mitigation techniques.

• Assist with the creation and integration of custom IP cores from scratch to meet specific mission and system requirements.

• Support continuous improvement of development workflows, including the use of AI-assisted implementation tools and automation where appropriate.

• Engage in knowledge sharing and mentorship within the team, helping colleagues learn new technologies and techniques as projects evolve.

Essential Skills

• At least 8 years of professional, full-time firmware engineering experience.

• At least 8 years of experience in FPGA firmware design using VHDL.

• At least 3 years of professional experience in hand-coded FPGA implementation.

• Exposure to AI-assisted implementation workflows in VHDL-based FPGA development.

• Bachelor's degree in computer engineering, electrical engineering, or an equivalent discipline.

• Strong proficiency in FPGA logic design, coding, simulation, and testing using VHDL.

• Demonstrated experience with synthesis, implementation, and timing analysis for complex FPGA designs.

• Ability to interpret and analyze customer specifications, datasheets, and technical manuals to guide design decisions.

• Experience supporting hardware and software teams in system bring-up, integration, and test.

• Solid understanding of digital design fundamentals, including high-speed interfaces and memory subsystems.

• Proficiency in debugging FPGA designs in a lab environment using appropriate tools and methodologies.

Additional Skills & Qualifications

• Experience working in Yocto-based environments.

• Familiarity with communication interfaces such as RS-422/RS-485, I²C, SPI, Ethernet/GigE, TCP/IP, UDP, and CAN.

• Experience with high-speed interfaces, including DDR or multi-gigabit transceivers.

• Experience with Xilinx/AMD Versal architecture and related toolchains.

• Experience with FPGAs and embedded systems operating in radiation environments, including understanding SEU/SEL impacts and mitigation techniques.

• Experience implementing FPGA-based image processing algorithms.

• Experience creating custom IP cores from scratch for FPGA implementations.

• Familiarity with C, C++, Python, or MATLAB and experience translating algorithms from scripted languages into HDL.

• Experience with software interfaces to FPGA logic, including interrupts and DMA.

• Experience with DDR4, Aurora, and high-speed transceiver design and verification.

• Familiarity with AXI Stream and AXI Memory Mapped interfaces.

• Experience with PCB design, schematic capture, and layout using tools such as Altium Designer.

• Interest in space systems, space domain awareness, and working on payloads deployed in orbit.

• Strong communication skills and the ability to work effectively within a multidisciplinary engineering team.
