About The Position

Castelion is seeking a Senior FPGA Engineer with strong experience in Vitis HLS and High-Level Synthesis workflows to support the development of high-performance digital systems for mission-critical hardware. This is a high-impact, full-time role focused on accelerating FPGA development by translating algorithmic and system-level requirements into efficient FPGA implementations using C/C++-based design flows.
You will work closely with our hardware, software, and systems engineering teams to implement and optimize FPGA-based processing capabilities. This role is ideal for an engineer who can ramp quickly, contribute immediately, and deliver optimized hardware implementations in a fast-moving development environment.

Requirements

• Bachelor's degree in Electrical Engineering, Computer Engineering, or related technical field
• Demonstrated experience using Vitis HLS or similar High-Level Synthesis tools
• Strong C/C++ programming experience for hardware-oriented development
• Experience generating VHDL or Verilog from HLS workflows
• Familiarity with FPGA development flows including simulation, synthesis, and timing closure
• Experience with Xilinx/AMD FPGA platforms and toolchains

Nice To Haves

• Experience with high-throughput signal processing, sensor processing, or real-time embedded systems
• Experience optimizing HLS pipelines for latency, parallelism, and memory bandwidth
• Familiarity with AXI interfaces, DMA, and FPGA-based accelerators
• Experience with Vivado and Vitis development environments
• Background in aerospace, defense, robotics, or other high-performance embedded systems

Responsibilities

• Develop FPGA-based implementations using Vitis HLS to generate VHDL/Verilog from C/C++ code
• Translate algorithms and system requirements into efficient hardware architectures optimized for performance and latency
• Develop and optimize high-level synthesis pipelines and dataflow architectures
• Collaborate with software, avionics, and systems engineers to integrate FPGA functionality into embedded platforms
• Perform FPGA simulation, synthesis, timing analysis, and hardware validation
• Optimize designs for throughput, determinism, and resource utilization
• Support hardware integration, board bring-up, and debugging as needed
• Contribute to verification and testing of FPGA functionality

Benefits

• All employees are granted long-term stock incentives as part of their employment as Castelion.
• All employees receive access to comprehensive medical, vision, and dental insurance, and the company offers three weeks of paid time off per year.
