## Job description

## ABOUT CODE METAL

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.

## SENIOR HLS ENGINEER ROLE

Code Metal is in the business of transpiling between different languages. This includes the transpilation tools enabled by AI and modern verification techniques — bridging the gap between algorithm development and deployment to embedded systems.

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.

## 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

## REQUIRED QUALIFICATIONS

- 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

## PREFERRED QUALIFICATIONS

- 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

## NICE TO HAVE:

- Bonus: Interest in or familiarity with LLM-assisted code transformation and readability tooling
- Experience with Git-based development workflows and CI/CD environments

## 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
- Paid Time Off (uncapped vacation, plus sick and public holidays)
- Flexible hybrid or remote work arrangement
- Relocation assistance for qualifying employees

Wage Transparency - The salary range for this role is not a guarantee of compensation or salary, as the final offer amount may vary based on factors including, but not limited to, individual proficiency, skills, experience, and location.

We are an equal opportunity employer. US Citizenship may be required for certain project assignments involving security clearance.

Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.

## About Code Metal

## Company Overview
- **One-liner**: Code Metal provides an AI-powered platform for verifiable code translation, enabling mission-critical industries to safely move software to different hardware architectures and languages with formal verification.
- **Entity Type**: Private (Series B)
- **Headquarters**: Boston, Massachusetts, United States
- **Founded**: 2023
- **Founders**: Not publicly disclosed

## Core Business
- **Primary industry/industries**: Software development tools; defense, automotive, aerospace, robotics, logistics
- **Target customers**: B2B enterprise – engineering teams in safety-critical sectors (defense, automotive, aerospace, medical devices)
- **Mission or purpose statement**: "Make AI trustworthy by safely delivering the last mile for mission critical industries" ([codemetal.ai](https://codemetal.ai/))

## Products & Services
- **Verifiable Code Translation Platform**: An AI-driven tool that automatically translates source code to a target architecture/language while generating a full test suite (functional and MCDC coverage) and formally verifying functional equivalence. Designed for safety-critical and compliance-heavy environments.

## Market Standing
- **Valuation**: Not disclosed directly; latest round implies a post-money valuation in the hundreds of millions (conflicting reports).
- **Key Metric – Total Funding**: Conflicting data – $178.45M or $184.45M (see sources). Latest round was a $125M Series B in February 2026, led by **Salesforce Ventures**. ([cbinsights.com](https://www.cbinsights.com/company/code-metal) and [pitchbook.com](https://pitchbook.com/profiles/company/548367-58))
- **Notable Investors/Partners**: J2 Ventures, Shield Capital, Overmatch Ventures, Smith Point Capital, RTX Ventures, Salesforce Ventures (lead Series B), and 20+ others.
- **Growth Signals**: 
  - Headcount of 63 (as of mid-2026), growing 182.8% YoY.
  - Active job postings: 57, up 714% YoY. 
  - Customers include a top‑5 global automotive OEM, a top aerospace company, and L3Harris.
  - Patents filed for code translation and program synthesis using LLMs.

## Competitive Advantages
- **Formal verification + AI**: Unlike typical AI code assistants, Code Metal guarantees functional equivalence through automated testing and compliance checks, making it suitable for systems where failure is not an option.
- **Chip portability**: Allows customers to avoid vendor lock-in by maintaining a single source-of-truth codebase deployable to any chip (ARM, RISC‑V, GPUs, etc.).
- **Track record in defense/aerospace**: Already deployed with L3Harris and major aerospace/automotive firms, providing a strong reference base.

## Strategic Focus
- **Go‑to‑market**: Deepening relationships with defense primes and automotive OEMs while expanding into robotics, telecommunications, and medical devices.
- **Product development**: Investing in compiler and AI tooling, modeling & simulation, formal methods, and GPU/accelerator support (evident from open positions).
- **Scaling team**: Aggressively hiring across engineering, research, and go‑to‑market roles (Boston, San Francisco, remote).

## Why Work Here
- **Culture & impact**: "Building a global team of exceptional builders" – focus on solving hard problems at the intersection of AI, compilers, and safety-critical systems.
- **Work policy**: Offers roles in Boston, San Francisco, and fully remote (US). Many engineering/research positions list "Boston, Remote, San Francisco".
- **Notable perks/engineering culture**: Exposure to cutting-edge AI and formal methods; opportunity to work with top defense contractors; high autonomy and a flat structure (only 63 employees).
