Senior/Staff Formal Verification Engineer

We’re looking for best-in-class engineers to join our existing top-notch team. When you join Untether AI, you will be part of the team that creates innovative hardware and delivers industry-leading AI performance and efficiency. Utilizing non Von Neumann techniques, you will help propel sustainable AI inference.

As part of this talented team of engineers, you are able to - and are excited to - architect, implement, verify and productize custom hardware designs. Being on our team means collaborating with an extremely bright group of people while tackling tough and interesting problems at the intersection of AI and hardware.

This position is for a Senior/Staff Formal Verification Engineer The successful candidate will use formal verification technologies to perform functional verification of design blocks inside Custom Al IPs. Formal technologies include Formal Property Verification, Sequential Equivalence Checking and Data path Validation.

Key Responsibilities

• Drive formal verification efforts to ensure the correctness and performance of Custom-AI hardware designs at both IP and Sub-system level.
• Develop and execute verification plans: from creating formal property test plans to executing them and providing final sign-off based on thorough verification
• Collaborate with hardware designers and architects to define the properties and requirements that need to be verified, ensuring alignment with system-level goals and performance expectations.
• Analyze and debug formal verification results, provide actionable feedback to design teams, and assist in improving design decisions to enhance verification outcomes
• Contribute to the continuous improvement of verification methodologies, tools, and internal processes, ensuring our verification practices remain at the forefront of industry standards.
• Stay up-to-date with the latest advancements in formal methods and AI hardware verification, applying new techniques to improve our verification strategies

Minimum Requirements

• Bachelor's or Master's degree in Electrical Engineering or Computer Engineering.
• 3+ years of proven experience in formal verification, especially Formal Property Verification.
• Hands-on experience with formal verification tools such as Cadence JasperGold, Synopsys VC Formal, or equivalent tools.
• Expertise in SystemVerilog Assertions (SVAs), with the ability to define, implement, and verify complex design properties is a must.
• Solid experience with RTL design (e.g., Verilog, VHDL) and understanding of digital design principles.
• A decent understanding of compute architecture, including CPU, GPU, or specialized AI hardware accelerators, and how to verify performance, timing, and functional properties within these architectures.
• Proficiency in scripting languages such as Python for automation and tool integration.

Preferred Skills & Experience

• In-depth understanding of complexity issues in formal property verification, including techniques to manage state space explosion, abstraction methods, and scalable verification strategies for large designs.
• Strong knowledge of AMBA protocols such as AXI, AHB, and APB, with the ability to verify the correctness of communication and data transfer between components using these protocols.
• Familiarity with the RISC-V Instruction Set Architecture (ISA) and its implementation in hardware, including the challenges of verifying custom RISC-V processors and accelerators.
