Senior AI Compiler Engineer — Research Team

Grow with us

The Mission

Most AI compiler engineers optimize models for GPUs that already exist. You're going to optimize them for silicon that doesn't yet.

As our Senior AI Compiler Engineer, you're not porting a framework, tweaking a runtime, or wrapping CUDA libraries. You're doing something far rarer and far harder — building a complete MLIR-based compiler stack from the ground up, purpose-built to run massive AI models like Llama 3 on bare-metal 5G/6G telecommunications silicon, where there's no OS to bail you out and every byte of memory is accounted for.

The gap between a research model and hardware-optimized silicon execution is one of the most technically brutal problems in the industry right now. You'll be the engineer who closes it.

What You'll Actually Be Doing

MLIR Architecture — Own the Stack

• Design and implement custom MLIR dialects from scratch — TableGen definitions, transformation passes, and the dialect conversion infrastructure that bridges the world of high-level AI graphs and the cold, hard reality of custom silicon. This is greenfield compiler work at its most consequential.

Lowering & Legalization — Zero Tolerance for Approximation

• Take high-level computational graphs exported from JAX and StableHLO and lower them, step by step, into hardware-specific IR without losing a single bit of mathematical fidelity. Every op must legalize. Every semantic must survive the descent.

Concurrency & Memory Modeling — Orchestrate the Machine

• There's no virtual memory here. No garbage collector. No safety net. You'll build static scheduling and tiling passes that choreograph data movement between HBM and on-chip local memory with surgical precision — because on this hardware, getting it wrong isn't a performance regression, it's a failure.

Production C++ — Code That Ships to Silicon

• You'll maintain a high-performance, modular, LLVM-based compiler codebase where correctness and determinism aren't aspirational — they're required. This is production compiler engineering in the truest sense.

Compensation and Benefits at Ericsson

At Ericsson, we know that our people are the key to our success. We offer a competitive package to help with your individual needs and goals.

Your Pay

The salary range for this position is dependent on various factors including, but not limited to, location, and the candidate’s

• Short-Term Variable Compensation Plan (select STV or SIP): Your pay also includes the opportunity for an annual bonus. Actual bonus payouts are based on performance of the business against the unit’s objectives, individual performance, and the individual bonus target. Certain eligibility and pro-ration rules apply.

Your Health

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.

Your Financial Security

We invest in both your short and long-term financial wellbeing. 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.

Your Time

Your work-life balance is important to us. 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.

Additional Benefits

Ericsson offers many other company-paid benefits such as financial wellness programs, educational assistance, matching gifts, and recognition programs.
