[Remote] FPGA Design Engineer, Senior

Note: The job is a remote job and is open to candidates in USA. Positron AI is building AI inference accelerators for low-latency, high-throughput large language model inference. The Senior FPGA Design Engineer owns FPGA designs from microarchitecture through lab-based silicon validation, develops networking and digital logic functions for FPGA and ASIC technologies, and brings up integrated FPGA, firmware, and software systems.

Responsibilities

• Create and release FPGAs through every development phase: microarchitecture, RTL design, physical implementation, timing closure, simulation validation, and lab-based silicon validation
• Define, design, implement, test, release, and support networking functions for FPGA and ASIC targets in partnership with inference system architects
• Partner with software, verification, and inference system architects and design engineers to implement digital logic functions in FPGA and ASIC technologies
• Build FPGA prototypes that validate architecture and design alternatives and inform trade-off decisions before committing to silicon
• Bring up and test systems that combine FPGA, firmware, and software functions alongside systems architects, hardware engineering, and software teams
• Drive trade-off analysis that improves customer experience and optimizes target technology resources for cost, size, power, performance, and features

Skills

• A Bachelor's degree in Electrical Engineering, a related discipline, or equivalent practical experience
• 5+ years of experience in FPGA and/or ASIC design and implementation
• Hands-on proficiency in SystemVerilog RTL coding
• A proven record of designing, testing, delivering, and supporting multiple FPGAs or ASICs that have shipped to customers
• Direct experience working with high-end Intel and Xilinx (AMD) FPGAs
• Strong working knowledge of modern ASIC and FPGA design and verification tools
• Deep practical experience across microarchitecture, RTL coding, FPGA optimization for timing and power, simulation, and validation
• This position is open to candidates currently authorized to work in the U.S. We cannot provide new visa sponsorship for this role but are open to facilitating H-1B visa transfers for eligible candidates
• Experience with artificial intelligence workloads, particularly large language model inference
• Familiarity with cocotb or other Python-based logic verification frameworks
• A track record of successfully fielding and supporting FPGA and ASIC products in production environments
• Strong analytical and problem-solving ability, paired with clear communication skills
• A collaborative mindset and the ability to work effectively within a cross-functional technical team

Benefits

• Fully company-paid medical, dental, and vision insurance for you and your dependents
• Company-paid life and disability coverage, with voluntary options to add more
• Supplemental hospital, critical illness, and accident coverage available
• Unlimited paid time off; we encourage everyone to truly unplug and recharge
• 13 paid company holidays
• Remote-first culture with a company-provided computer and home office setup
• Equity
• 401(k) with company matching, eligible from day one
