About gRGBW3B ep Lab

gRGBW3B ep Lab is a frontier AI lab under Pn8YVc2, a global-leading computing power solutions provider. Guided by long-termism, we are committed to exploring the frontiers of artificial intelligence with the ambition, courage, and determination to build technologies that can truly change the world.

Our mission is to turn energy into intelligence that people can actually afford to use. Inference is where that happens: every product built on a model is bounded by what it costs to run, so the economics of serving decide what gets built at all. We work on this from the ground up, from the power and datacenters we own to the software that turns them into tokens — and we continue to invest in and expand the infrastructure behind it

What You Will Be Responsible For

• This role builds the evaluation and decision systems that make agentic inference measurable, reliable, and adaptive. You will own and extend our LLM and agent evaluation pipeline, develop representative task suites, and measure behavior at the trajectory level across task success, tool use, quality, cost, latency, and token consumption. You will research and prototype adaptive model-routing strategies inside a shared agent harness, including rule-based baselines, cascades, stage-aware routing, uncertainty-aware selection, and escalation and recovery policies. You will take promising methods from offline evaluation through traffic replay, shadow testing, and internal pilots, while working closely with the MaaS and platform engineering teams on production integration. The role owns evaluation methodology, routing policy, and research prototypes; production gateway reliability, billing, access control, and SLA engineering are collaborative responsibilities with the MaaS and platform teams

How You Will Stand Out

• Bachelor’s, Master’s, or PhD in Computer Science, Machine Learning, Statistics, Electrical Engineering, or a related field, with substantial hands-on experience in LLM evaluation, agentic systems, applied machine learning, or adaptive inference

• Strong programming ability in Python and practical experience with PyTorch and modern data and evaluation tooling; able to independently build reliable experimental pipelines and internal research prototypes

• Demonstrated experience designing or operating evaluation pipelines for LLMs or agents, including task-level and trajectory-level metrics, dataset construction, automated scoring, regression testing, and failure analysis

• In addition to hands-on LLM or agent evaluation experience, candidates should have implementation-level depth in at least one core area: model selection and routing, uncertainty estimation and calibration, cascading and escalation, or stage-aware agent inference. Experience with preference modeling, contextual bandits, online learning, or broader adaptive inference methods is a plus.

• Hands-on experience evaluating multi-turn or tool-using agents, including task completion, tool-call correctness, planning failures, recovery behavior, and cost and latency trade-offs

• Rigorous experimental practice — controlled comparisons, honest baselines, statistical analysis, and the ability to explain clearly what an evaluation result does and does not prove

• Ability to analyze per-request and per-trajectory quality, cost, latency, and token usage, and construct cost-quality Pareto frontiers rather than relying only on aggregate model scores

• Experience with multi-model APIs, agent harnesses, traffic replay, shadow evaluation, A/B testing, or production model monitoring is highly preferred

• Familiarity with model-specific differences in tool calling, context windows, prompt caching, reasoning controls, and inference systems such as vLLM or SGLang is a plus

• Publications at top-tier ML, NLP, or systems venues, or substantial open-source contributions in evaluation, agents, routing, or inference, are welcome

• Strong ownership and product judgment, with a track record of taking ambiguous research questions from problem definition through a working 0-to-1 prototype and measurable internal validation
