High Level Synthesis Compiler Engineer

Responsibilities

• Develop and optimize our compiler for the FPGA design flow: IR and lowering, analysis and transformation passes, correctness- and QoR-driven optimizations, and scalability (runtime and memory) on large designs
• Work closely with customers to enable what they want to do : understand target applications, workflows, and success criteria; advocate for the capabilities, quality-of-results, and turnaround time they need; and turn that into concrete compiler and flow improvements-not only reactive support.
• Mentor talented engineers through code reviews, design reviews, and technical coaching; help grow ownership, design judgment, and execution quality across the team.
• Document and explain behavior, limitations, and workarounds for internal and external audiences where appropriate.
• Stay current with EDA and compiler technology (including LLVM/MLIR ecosystems where applicable), FPGA design practices, and relevant standards.
• Estimated Salary Range: $124.1K - $179.7K CAD
• We use artificial intelligence to screen, assess, or select applicants for the position. This posting is for an existing vacancy. Canadian work experience is not required for this role.

Requirements

• Required Qualifications:
• Bachelor's or Master's Degree in Electrical Engineering, Computer Engineering, Computer Science or a close related field
• 8+ years of professional experience building compilers, LLVM/MLIR-based tools, or EDA/FPGA implementation software .
• Strong C++ for production systems (performance, multi-threading, large codebases).
• Hands-on experience with MLIR and/or LLVM (IR design, passes, backends, or integration with a larger compiler or EDA flow).
• Solid digital design and FPGA background : LUT/FF/BRAM/DSP primitives, clocks and timing, and how tool choices affect QoR.
• Familiarity with FPGA or ASIC implementation flows (synthesis, place-and-route, STA, constraints) and what can go wrong in real designs.
• Communication and collaboration : comfortable working with customers and translating their goals into actionable engineering work.
• Mentorship mindset : proven ability to develop other engineers through review, pairing, and clear technical guidance.
• PhD in Electrical Engineering, Computer Engineering, Computer Science or a close related field
• Exposure to simulation, formal, or debug environments, or to high-level design flows (e.g. HLS) and how they map to the backend.
• Experience shipping software used by external customers or large internal user bases.
• Job Type:
• Regular
• Shift:
• Shift 1 (Canada)
• Primary Location:
• Toronto, Ontario, Canada
• Additional Locations:
• Posting Statement:

Additional Information

Job Details: Job Description: As a High Level Synthesis Compiler Engineer at Altera, you will focus on our compiler and the software that turns RTL and constraints into realizable designs: lowering, optimization, and integration with the broader implementation, timing, and debug flow. You will build reliable and scalable tools; mentor talented engineers ; and stay close to customers so their hardest design goals stay technically possible and practical in our tools.
