Responsibilities
- Lead or co-lead technically complex ML engineering projects from initial customer discussions through implementation and delivery
- Design, build, and improve LLM training and post-training pipelines, including data ingestion, preprocessing, fine-tuning, evaluation, and experiment tracking
- Implement and optimize evaluation systems for LLMs and multimodal models, including offline benchmarks and task-specific test harnesses
- Integrate human-in-the-loop and AI-augmented evaluation signals into model development workflows
- Build robust infrastructure and tooling for reproducible experimentation, metrics logging, and regression monitoring
- Diagnose model behavior and pipeline failures, including data issues, training instability, metric inconsistencies, and evaluation drift
- Collaborate with Language Data Scientists and Applied Research Scientists to translate evaluation frameworks into executable systems
- Work closely with customer technical stakeholders to understand goals, constraints, and success criteria; propose and implement technically sound solutions
- Contribute to internal research and platform development, including benchmark frameworks, evaluation tooling, and post-training workflow improvements
- Contribute to best practices and standards for LLM training, evaluation, and quality assurance across projects
- Mentor junior engineers and contribute to technical design reviews, documentation, and engineering rigor across the team
Skills
- BS/MS/PhD in Computer Science, Machine Learning, AI, Applied Mathematics, or a related quantitative technical field
- 2-3 years of relevant industry or research engineering experience in ML/AI systems
- Hands-on experience with LLM training / fine-tuning / post-training, including at least one of: supervised fine-tuning (SFT), preference optimization (e.g., DPO or related methods), RLHF / RLAIF-style workflows, task- or domain-adaptation of foundation models
- Strong programming skills in Python and experience building production-quality ML code
- Experience with modern ML frameworks (e.g., PyTorch, JAX, TensorFlow) and model libraries/tooling (e.g., Hugging Face ecosystem, vLLM, distributed training stacks)
- Experience designing and implementing evaluation pipelines for LLM/ML systems, including metrics computation, dataset handling, and experiment comparisons
- Strong understanding of data pipelines and ML systems engineering, including reproducibility, observability, and debugging
- Experience with large-scale distributed ML systems and performance optimization for training/evaluation workloads (GPU/accelerator environments preferred)
- Experience with large-scale data processing and workflow orchestration in support of model training/evaluation
- Ability to collaborate directly with technical stakeholders including research scientists, ML engineers, data engineers, and customer technical leads
- Strong written and verbal communication skills, including the ability to explain complex technical tradeoffs to both technical and non-technical audiences
- Experience training, fine-tuning, and evaluating transformer-based models
- Understanding of post-training workflows and model iteration loops
- Familiarity with inference-time considerations (latency, throughput, memory/performance tradeoffs) where relevant to evaluation or deployment
- Experience implementing automated evaluation pipelines and test harnesses
- Experience with experiment tracking, versioning, and reproducibility practices
- Ability to assess metric quality and ensure consistency across model comparisons
- Proficiency in Python and strong software engineering fundamentals
- Experience with data processing pipelines, storage formats, and scalable dataset workflows
- Familiarity with CI/CD, testing, and engineering quality practices for ML systems
- MS/PhD preferred
