Job Category: Subject Matter Expertise

Evaluate the quality, correctness, and completeness of GPU/accelerator kernel development tasks used to train and evaluate a frontier AI lab’s models. You’ll assess numerical correctness, performance-benchmarking fairness, task scoping, and compilation/runtime validity across diverse kernel task types — and provide clear, rubric-based written feedback. Basic Qualifications • 3+ years of hands-on experience developing, optimizing, or verifying GPU/accelerator kernels in at least two of: CUDA, Triton, NKI, or Pallas (JAX) • Strong understanding of numerical-correctness criteria for kernels (abso

Support a high-priority technical-expert panel for a frontier AI lab as an Expert Interviewer. We’re seeking an experienced interviewer to help vet shortlisted engineers across GPU kernel development, security & vulnerability research, and ML-compiler / accelerator domains for an AI model training-and-evaluation engagement. You’ll run short, structured interviews and give our team a clear, evidence-based read on each expert’s fit.

Evaluate the quality, correctness, and hardware-appropriateness of Neuron Kernel Interface (NKI) development tasks used to train and evaluate a frontier AI lab’s models. You’ll assess CUDA→NKI migration fidelity, Trainium-specific performance-optimization quality, and cross-platform numerical-correctness standards — and provide clear, rubric-based written feedback. Basic Qualifications • 2+ years of hands-on experience developing or optimizing kernels using the Neuron Kernel Interface (NKI) targeting AWS Trainium/Inferentia2 hardware • Strong understanding of NKI-specific development patterns:

Mercor is partnering with a leading language-learning platform to recruit experienced Spanish tutors for a short-term project involving recorded, one-on-one tutoring sessions. Tutors will conduct genuine Spanish lessons with native English-speaking learners at different proficiency levels. The goal is to produce natural, high-quality conversations that reflect authentic language-learning experiences.

Evaluate the quality, correctness, and cloud-architecture soundness of AWS serverless and infrastructure-as-code tasks used to train and evaluate a frontier AI lab’s models. You’ll assess multi-service serverless designs, IaC fidelity, and cross-service integration correctness — and provide clear, rubric-based written feedback. Basic Qualifications • 3+ years hands-on experience building multi-service AWS serverless applications (Lambda, API Gateway, DynamoDB/Streams, S3, EventBridge, SNS/SQS, Step Functions) • Strong experience with infrastructure-as-code (AWS CDK, CloudFormation, or SAM) • D

Evaluate the quality, correctness, and production-readiness of Kubernetes tasks used to train and evaluate a frontier AI lab’s models. You’ll assess cluster-operations scenarios, manifest correctness, and failure-mode troubleshooting — and provide clear, rubric-based written feedback. Basic Qualifications • 3+ years hands-on production Kubernetes experience (EKS/GKE/AKS or self-managed) • Deep understanding of cluster internals: CNI/DNS/ingress, PV/PVC storage, RBAC, and failure modes (CrashLoopBackOff, OOMKilled, scheduling/eviction) • Experience authoring and reviewing manifests / Helm chart

Evaluate the quality, correctness, and methodological rigor of applied machine-learning tasks used to train and evaluate a frontier AI lab’s models. You’ll assess experiment design, model-selection reasoning, and evaluation methodology — and provide clear, rubric-based written feedback. Basic Qualifications • 3+ years hands-on applied/experimental ML (experiment design, model selection, hyperparameter tuning, evaluation methodology) • Strong grasp of data-quality rigor: leakage detection, metric gaming, and train/test/CV hygiene • Proficiency with standard ML frameworks (PyTorch, TensorFlow, s

Evaluate the quality, correctness, and reproducibility of software-engineering benchmark tasks used to train and evaluate a frontier AI lab’s models. You’ll assess repository-level tasks, reference patches, test harnesses, and grading integrity — and provide clear, rubric-based written feedback. Basic Qualifications • 3+ years professional software engineering • Real open-source contribution or maintainer experience (merged PRs, committer / maintainer roles) • Strong ability to audit reference patches, test runners, and Docker isolation, and to detect answer leakage / reward hacking • Fluency
