SoC Hardware Architect

Ericsson • Austin, TX

31d • Onsite

About The Position

As Principal SoC Hardware Architect, you will own the most consequential technical contract in the company: the binding agreement between what AI workloads demand, what software systems can express, and what custom silicon can physically deliver. This is the highest-leverage engineering seat in the building — the person who looks at a next-generation LLM, a multimodal inference pipeline, or a signal processing workload and answers the question that determines whether a chip program succeeds or settles: "Here's exactly what this workload needs from silicon — and here's the proof it will work before we ever tape out." Your decisions won't live in documents. They'll be etched into hardware. Your performance models will guide compute investments. Your architectural direction will shape memory hierarchies. Your cross-team alignment will determine whether the company builds capable hardware — or hardware nobody else can touch.

Requirements

• 12+ years of industry experience across AI, systems, or silicon
• Proven experience at the intersection of hardware and intelligent compute systems
• Hardware/software co-design leadership across full product cycles
• Demonstrated performance modeling expertise — analytical, simulation, or cycle-approximate
• Track record of influencing architectural and product decisions across multiple technical organizations
• Exceptional written communication and technical specification ability
• Strong Python and C++ skills

Nice To Haves

• Experience with custom silicon, accelerators, or advanced hardware platforms
• Prior involvement in ISA definition, memory hierarchy design, or accelerator roadmap decisions

Responsibilities

• Analyze workload specific testcases tailored to real-world applications, using LLMs, multimodal systems, signal processing pipelines, inference engines - and translate them into the concrete hardware requirements that can be implemented.
• You are the bridge that doesn't bend. You connect model engineering, AI infrastructure, and silicon architecture teams so that every major hardware investment is both architecturally sound and software-accessible. When workload ambition outpaces hardware capability, you find the path forward. When silicon innovation creates a performance unlock, you make sure the software stack can actually reach it.
• Before a single gate is placed, your analytical, simulation, and cycle-approximate performance models are already shaping the architecture. You build and create the performance modeling environment that determine compute investments, memory hierarchy decisions, and feature prioritization — turning uncertainty into defensible, data-driven direction.
• You profile real workloads on real and future platforms. You find the bottlenecks — in memory, compute, scheduling, and architecture — and you feed those findings directly into the next hardware and software cycle. No guesswork. No assumptions. Just ground truth.
• You align people who think in different languages. Hardware architects, AI researchers, and infrastructure teams all operate with different mental models and different vocabularies. You translate across all of them — grounding every product decision in real workloads, measurable constraints, and practical execution paths.
