Job description

Job Description

Microchip’s FPGA software engineering team is at the forefront of developing advanced Electronic Design Automation (EDA) software, empowering customers to program and optimize Microchip FPGAs. Our comprehensive software suite supports the entire FPGA design flow—from initial design entry and synthesis, through place-and-route, timing analysis, power optimization, and simulation—enabling users to achieve high-performance, reliable solutions.

Within this team, the High-Level Synthesis (HLS) group is driving innovation in system‑level FPGA design. Our SmartHLS® tool enables customers to describe hardware accelerators in C/C++, which are then compiled into efficient FPGA implementations using state‑of‑the‑art LLVM/MLIR compiler infrastructure. The PolarFire® System Designer further expands design possibilities, providing a robust platform for building complete SoC solutions that seamlessly integrate RISC‑V processors with FPGA‑based hardware accelerators, while supporting comprehensive system‑level verification.

As a Software Engineer on our team, you will play a pivotal role in shaping the future of FPGA design tools. Your primary focus will be on compiler development (LLVM/MLIR‑based), with opportunities to contribute to broader SoC design and verification workflows. You will collaborate closely with talented engineers in an agile, supportive environment, tackling complex technical challenges that directly impact customer productivity and accelerate time‑to‑market. This position offers significant opportunities for professional growth, innovation, and making a tangible difference in the EDA industry.

The software engineering team is based in Toronto. The Microchip office is located in the downtown financial core at 67 Yonge Street.

Responsibilities

• Develop, verify, and maintain advanced analysis and transformation passes for our state‑of‑the‑art high‑level synthesis (HLS) compiler, enabling the generation of high‑performance FPGA designs.
• Optimize HLS‑generated hardware architectures to enhance power efficiency, performance, and area utilization of the resulting hardware circuits.
• Analyze complex, real‑world customer applications created with high‑level synthesis to identify opportunities for performance and area improvements.

and implement new HLS features as needed.
