About The Position

Principal AI Model Architect, Austin, Texas This is not a remote work opportunity The Rarest Role in 5G Silicon. Built for the Rarest Kind of Engineer. The Mission Most AI runs on someone else's hardware. You're going to design the hardware around the AI. As the Principal AI Model Architect, you sit at the most critical intersection in our entire silicon program — the place where bleeding-edge AI research collides with custom ASIC reality. You are the "Voice of the Model" — the person who takes ambitious algorithms born in a research lab and answers the hardest question in the building: "How do we actually run this on silicon we haven't built yet — and make it faster than anyone else on the planet?" You won't just map models to hardware. You'll shatter them — strategically, surgically — across a heterogeneous ASIC architecture purpose-built for the demands of next-generation 5G AI. Your decisions will be etched into silicon. Your projections will determine tape-out confidence. Your golden models will be the source of truth that an entire SDK team builds against. This is not a support role. This is the role that makes the chip worth building. What You'll Own The Hardware-Software Bridge You are the translator between two worlds that rarely speak the same language. You'll take complex AI and RAN algorithms — Transformers, Grouped Query Attention, Positional Embeddings — and forge them into concrete hardware specifications for the ASIC team and precise lowering requirements for the SDK team. When there's ambiguity between what research wants and what silicon can deliver, you resolve it. Model Partitioning & Tiling Strategy Massive parameter models don't fit neatly onto a chip. You'll define exactly how they do — determining the partitioning, tiling, and memory staging strategies that make heterogeneous execution not just possible, but optimal. This is where deep theoretical knowledge meets brutal real-world constraint, and where the best architects separate themselves from everyone else. Golden Model Ownership You maintain the Source of Truth — reference implementations in JAX/PyTorch that capture the researcher's intent with zero ambiguity. You'll work shoulder-to-shoulder with the SDK team to ensure that what comes out of the MLIR compiler is exactly what went into the model. 100% fidelity. No exceptions. Cycle-Accurate Performance Projection Before a single gate is synthesized, you'll use your architectural intuition and simulation expertise to project exactly how next-generation silicon targets will perform. Your numbers will drive investment decisions, microarchitecture tradeoffs, and tape-out timelines. You're not guessing — you're proving it before it exists. Join our Team Why This Role. Why Now. Ericsson Silicon is building custom ASICs at the most advanced technology nodes available — purpose-engineered to run AI at the edge of a global 5G network. The scale is real. The stakes are real. The team is world-class. This is the kind of role that defines a career — the rare opportunity to have your architectural decisions running inside infrastructure that connects billions of people. If this is the role you've been waiting for, we want to hear from you.

Requirements

Model Architecture Mastery
Hardware-Aware ML — For Real
Framework Mastery at the Metal
Performance Modeling Depth

Nice To Haves

Telecom DNA: You've applied AI to real RAN workloads — beamforming, channel estimation, L1/L2/L3 signal processing. You understand that 5G AI is not the same as data center AI.
Compiler Fluency: You don't need to write MLIR passes from scratch — but you absolutely know the difference between a high-level computation graph and a linearized execution schedule, and you can have an intelligent conversation about what happens in between.
Numeric Instinct: You've worked with complex-number representations in AI models and understand how they map to specialized DSP and matrix hardware. You know why this matters and where it breaks.

Benefits

Ericsson offers excellent health benefits including the choice of three medical plan options and a dental plan option that allow an employee to select the level of coverage that suits their needs. Employees will receive company credits in an amount equal to the cost that Ericsson pays toward the cost of their medical and dental premiums for themselves and eligible covered dependents.
The Ericsson US 401(k) Plan offers an automatic 3% company contribution and Ericsson match $1 for every $1 you put into the 401(k) Plan on the first 3% of your eligible pay, plus 50 cents on every $1 on the next 2% of eligible pay. When you contribute at least 5% of eligible pay, you are receiving Ericsson’s full matching contributions of 4%. Matching and company automatic contributions stop when your total eligible pay for the year reaches the IRS limits. Employees will also receive company credits in an amount equal to the cost of basic life insurance and basic accidental death and dismemberment coverage, as well as short-term and long-term disability coverage. Employees also have the option to participate in Ericsson’s Stock Purchase Plan.
New employees are provided a minimum of 15 days of accrued vacation, up to 3 personal days per year, 11 annual holidays, 8 hours of volunteer time, and 80 hours of sick time annually. Please note paid time off is pro-rated based on the employee’s start date. Furthermore, Ericsson provides up to 16 weeks of paid maternity leave and 6 weeks of parental or adoption leave at 100% of pay.
Ericsson offers many other company-paid benefits such as financial wellness programs, educational assistance, matching gifts, and recognition programs.
