About Positron AI

Positron AI is building next-generation AI inference accelerators designed from the ground up for low-latency, high-throughput large language model inference. Our first-generation ASIC, Asimov, is a cutting-edge accelerator targeting frontier AI workloads, with additional generations already underway.

Role Overview

We're looking for an exceptional Principal ASIC Architect to help define the future of AI inference hardware. You will collaborate across architecture, software, machine learning, systems, and silicon implementation to design next-generation AI accelerators capable of serving rapidly evolving frontier models. This role requires exceptional technical breadth, balancing mathematical understanding, ML trends, systems architecture, and practical silicon implementation. This may be the single most important technical hire after the Chief Architect.

Key Responsibilities

Architectural Exploration

Own architectural exploration across the evolving landscape of transformer models, MoE, sparse models, and long-context inference.
Evaluate emerging techniques including speculative decoding, continuous batching, KV-cache evolution, sub-quadratic and linear attention, and state-space models.
Assess memory architectures, communication architectures, and interconnects for next-generation accelerators.

Performance Modeling

Develop analytical models and build simulation frameworks to evaluate architectural tradeoffs.
Estimate latency, throughput, bandwidth, memory and compute utilization, scaling efficiency, power, area, and cost.

Hardware/Software Co-Design

Partner closely with compiler, runtime, system software, firmware, ASIC engineering, and ML research teams to align hardware direction with real workload needs.

ASIC Specification & Roadmap

Develop architecture documents and define subsystem interfaces.
Evaluate tradeoffs across competing architectural directions and guide the future product roadmap.

Industry Awareness

Track new LLMs, reasoning models, research papers, hardware competitors, academic research, and emerging algorithms to keep Positron's architecture ahead of the field.

AI-Enabled Engineering

Use AI to accelerate research, performance analysis, architecture exploration, simulation generation, and documentation.

Required Qualifications

15+ years of experience in ASIC architecture.
Deep expertise in AI accelerator design and high-performance SoCs.
Hands-on experience building performance models for memory systems and interconnects.
Strong hardware/software co-design ability.
Excellent written and verbal communication skills.

Preferred Qualifications

Experience with GPU architecture.
A solid grasp of ML systems, distributed inference, and large-scale serving.
Deep knowledge of transformer internals.
Compiler experience.
A track record of research publications.

Leveling & Scope

While this role is currently posted at a specific level, we are a growth-oriented organization and are open to hiring at a more senior level for the right candidate. Please note that this job description serves as a focused but generalized overview of the role; specific responsibilities and impact expectations will be tailored to the experience and seniority of the final hire.

What Success Looks Like

Success in this role looks like helping define future Positron architectures and creating a scalable architectural direction that bridges software and hardware, influencing products that remain competitive for years despite rapidly evolving AI models.

Why Join Us?

Shape the core architecture of Positron's AI inference accelerators at a foundational level, with outsized influence over the company's technical direction for years to come.
Work at the intersection of frontier AI research and silicon implementation, tackling problems few architects in the industry get to own end to end.

Compensation & Benefits

The base salary range for this role is $200,000 – $300,000.

Please note that the figures provided represent the base salary range only and do not include other elements of our total compensation package, equity, or comprehensive benefits.

At Positron AI, we value the unique expertise each candidate brings. While the range above reflects our typical expectation for
