Senior High-Level Synthesis (HLS) Engineer

Code Metal • Boston, MA

4d • Hybrid

About The Position

Code Metal is redefining code translation for mission-critical industries, helping defense partners move more quickly and reliably from algorithm to silicon. Our platform accelerates deployment of DSP, RF, communications, and embedded signal processing algorithms onto heterogeneous compute targets, including GPUs, FPGAs, ASICs, and edge SoCs. We also support automotive, aerospace, and semiconductor partners deploying complex algorithms onto constrained hardware with speed and rigor.

We are currently looking for a senior high-level synthesis engineer interested in architecting and expanding our capabilities towards creating production-ready RTL from high-level algorithm descriptions. This role focuses on HLS integration, architectural transformation, and vendor-agnostic RTL generation. You will be joining a team that values technical rigor, ownership, and collaboration across disciplines.

Requirements

• 5+ years of hands-on experience with High-Level Synthesis, including at least one commercial HLS tool (Catapult, Vitis HLS, Stratus, or equivalent)
• Solid HLS modeling background regarding fixed-point arithmetic, bit-accurate types, synthesis pragmas and modeling trade-offs
• Scripting experience in Python for development, toolchain automation and testing
• Strong debugging and problem-solving skills
• Experience with simulation and functional verification flows

Nice To Haves

• Experience using Linux-based development environments
• Solid understanding of RTL / VHDL
• Understanding of FPGA architectural capabilities and constraints
• Knowledge of verification methodologies and testbench development
• Experience with DSP algorithms and applications using Python/MATLAB
• Bonus: Interest in or familiarity with LLM-assisted code transformation and readability tooling
• Experience with Git-based development workflows and CI/CD environments

Responsibilities

• Build a vendor-agnostic HLS integration layer supporting multiple backends
• Develop post-HLS readability and optimization passes to produce human-auditable RTL
• Leveraging Agentic AI and verification capability within Code Metal
• Contribute to CI/CD qualification including automated RTL simulation, functional verification, and regression testing
• Evaluate HLS tool output quality, track vendor licensing requirements, and inform toolchain strategy

Benefits

• Pay depends on experience, but we strive to be at the upper end of the salary range
• Health care plan with 100% premium coverage, including medical, dental, and vision
• 401k with 5% matching
