This work will be done at a facility located in Cedar Park, TX. This role emphasizes designing, implementing, optimizing, and verifying FPGA firmware for Microchip PolarFire SoCs, which combine RISC-V processors with low-power FPGA fabric for high-reliability applications. As the counterpart to our Linux software engineering team, you will collaborate closely on integrating FPGA logic with custom Linux distributions, ensuring seamless performance on custom hardware. You will work in a fast-paced, collaborative environment to deliver robust firmware for mission-critical space applications in industries such as aerospace, defense, and industrial automation. Through this partnership, Cimarron supplies skilled technical talent in support of our customer's advanced launch and space systems. This customer designs and builds small- to medium-lift launch vehicles, lunar landers, and orbital vehicles for government and commercial missions from low Earth orbit to the Moon and beyond. Together, our teams leverage advanced carbon composite structures, patented propulsion technologies, and common components across platforms to move fast, improve reliability, and deliver payloads at a lower cost. Key Duties: * Design, develop, and verify FPGA logic using VHDL/Verilog/SystemVerilog for Microchip PolarFire SoCs, including programmable logic, DSP blocks, and high-speed interfaces (e.g., PCIe, Ethernet, SERDES). * Create and optimize IP cores and custom peripherals/accelerators tailored to PolarFire's architecture. * Integrate FPGA firmware with embedded processors (e.g., RISC-V cores) and collaborate with software teams to support Board Support Packages (BSPs) and Linux kernel drivers. * Build RTL verification environments with testbenches using UVM methodologies for design correctness and coverage. * Perform functional verification, simulation, regression testing, and coverage analysis (e.g., functional, code, assertion). * Conduct synthesis, place-and-route, timing analysis, and debugging using tools like Libero SoC, logic analyzers, and oscilloscopes. * Implement radiation-tolerant and fault-tolerant designs for space-grade applications. * Develop automated test benches and CI pipelines for verification, including hardware-in-the-loop testing. * Contribute to system architecture, security, and real-time processing requirements. * Participate in code reviews, documentation, and stay updated on FPGA technologies and open-source contributions. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Unleashing the Full Potential of the Arm Architecture – Write Once, Deploy Anywhere](https://www.wearedevelopers.com/videos/940-unleashing-the-full-potential-of-the-arm-architecture-write-once-deploy-anywhere) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
