Applied AI Engineer, Inference

What Youll Do

Description of the team:

The Inference team is responsible for delivering high-performance model serving capabilities that meet the needs of real production workloads. We work at the intersection of model behavior serving systems hardware and customer requirements to improve throughput latency reliability and quality across our inference stack.

About the role:

We are looking for an Applied AI Engineer to help us understand measure and improve the real-world performance of our inference the near term this role will focus on building and running rigorous benchmarks profiling model and system behavior identifying bottlenecks and driving targeted optimizations for both platform-wide and customer-specific workloads. This role is intentionally scoped around applied performance work in support of the Inference organization. Initial responsibilities center on benchmarking optimization and workload-driven research rather than broad ownership of frontier model research agendas. Over time the scope of the role is expected to broaden as the team and product mature.

• Build and maintain benchmarking workflows that measure latency throughput quality regressions and cost across priority models and serving configurations.
• Benchmark our inference stack against realistic customer workloads and external provider baselines to identify performance gaps and improvement opportunities.
• Profile model-serving behavior across frameworks runtimes and hardware configurations to find bottlenecks in prefill decode KV cache usage batching graph capture quantization and related systems.
• Drive targeted optimization efforts for specific customer and product workloads including tuning serving configurations evaluating runtime features and validating changes against representative traces and benchmarks.
• Design and run experiments on model-serving techniques such as quantization speculative decoding caching strategies routing and other inference optimizations with careful attention to quality and correctness tradeoffs.
• Partner closely with inference platform engineers to productionize improvements and establish repeatable workflows for performance testing and regression detection.
• Produce clear technical writeups and recommendations that help the team make better decisions about model configurations runtime choices hardware allocation and customer-specific deployment strategies.
• Contribute additional applied research over time as needed to support inference quality optimization and product performance goals.

Who You Are

• 4 years of experience in machine learning systems performance engineering or adjacent applied engineering work.
• Strong programming skills in Python and comfort working in production engineering environments.
• Experience running empirical evaluations benchmarks or experiments and translating results into concrete engineering decisions.
• Familiarity with LLM inference systems and tools such as vLLM SGLang TensorRT-LLM or similar model-serving stacks.
• Understanding of the practical tradeoffs involved in latency throughput batching GPU utilization quantization and quality regression analysis.
• Ability to work across model systems and product boundaries and stay focused on outcomes that matter for customers.
• Strong written communication and a bias toward making technical work legible and reproducible for others.

Preferred

• Experience optimizing inference workloads on modern GPU hardware.
• Experience with profiling tools such as Nsight Systems PyTorch profilers or custom telemetry pipelines.
• Familiarity with benchmark suites and evaluation frameworks for coding reasoning or agent workloads.
• Experience using real production traces or customer traffic patterns to guide optimization work.
• Experience balancing model quality and serving performance when evaluating quantization speculative decoding or other acceleration strategies.

Wondering If Youre A Good Fit

We believe in investing in our people and value candidates who can bring their own diversified experiences to our teams - even if you arent a 100% skill or experience match. Here are a few qualities weve found compatible with our team. If some of this describes you wed love to talk.

• You love turning ambiguous performance problems into concrete measurements and engineering plans.
• Youre curious about how model behavior systems architecture and hardware choices interact in production inference workloads.
• Youre an expert in running disciplined experiments and using data to drive practical performance improvements.
