Senior Forward Deployed Engineer, Synthetic Data

Snorkel AI, Inc.; New York, Northern (NY, KY); Hybrid; USD 180,000 - 320,000; Full time

Job summary

Snorkel AI, Inc. is hiring a Senior/Staff Forward Deployed Engineer focused on Synthetic Data Generation.

You will lead technical execution of customer engagements, designing scalable data pipelines, evaluating datasets, and delivering production-grade data assets for model training and evaluation. You will translate complex challenges into concrete data strategies, prototype solutions, and scalable workflows.

Qualifications

• 5+ years of experience in machine learning engineering, data science, applied AI, forward deployed engineering, or a similar technical role
• Strong Python skills and experience building reliable production data or ML systems, including containerizing with Docker and deploying on cloud platforms (e.g., AWS, GCP, or Azure)
• Hands-on experience with LLMs—building model-based applications and data workflows with the modern GenAI/LLM stack, and integrating systems, models, and data sources through APIs
• Strong understanding of ML experimentation and evaluation, including defining metrics and using empirical results to guide technical decisions
• Experience building synthetic data, data augmentation, or model-generated training and evaluation datasets
• Experience with LLM evaluation techniques, including LLM-as-a-judge, model-based evaluation, rubric-based evaluation, or custom evaluators
• Demonstrated ability to take ambiguous technical problems from problem definition through delivery, with strong technical communication and experience working directly with customers and cross-functional stakeholders
• Experience serving as a technical lead—setting technical direction, driving architecture and key decisions, mentoring engineers, and creating reusable approaches that influence broader engineering or product outcomes
• Experience developing datasets for fine-tuning, preference optimization, or benchmarking, including human-in-the-loop generation and review workflows
• Experience building agentic environments and tasks—repo-scale coding tasks, tool-agent-user interaction design, and agent tool protocols and interoperability
• Experience with reinforcement learning for LLMs, including reward and verifier design and RL with verifiable rewards (RLVR)
• Experience working in fast-paced, customer-facing environments where requirements and technical approaches evolve quickly

Responsibilities

• Design and build scalable synthetic data generation, transformation, filtering, and evaluation pipelines for complex AI use cases
• Translate model objectives, failure modes, and data gaps into synthetic data strategies, experiments, and technical specifications
• Develop LLM-and ML-assisted workflows to generate high-quality training and evaluation datasets across targeted behaviors, domains, and edge cases
• Build automated evaluators, quality checks, and measurement frameworks to assess correctness, relevance, diversity, coverage, and adherence to customer requirements
• Design and run experiments to measure the impact of synthetic data on downstream model performance and iteratively improve generation approaches
• Package and deliver production-grade datasets with standardized formats, quality assurance, and clear documentation
• Lead technical workstreams from initial solution design through production delivery, navigating ambiguity and making sound technical decisions
• Build, refine, and iterate on solutions that address customer needs, incorporating feedback to ensure the delivered work provides tangible value
• Rapidly prototype and productionize solutions across models, data pipelines, APIs, and custom applications
• Communicate technical tradeoffs, experimental results, and recommendations clearly to technical and cross-functional stakeholders
• Serve as a trusted technical partner to customers and internal delivery teams, resolving complex blockers and driving alignment
• Identify recurring patterns across customer engagements and turn successful solutions into reusable pipelines, evaluators, tooling, and best practices
• Define and improve technical standards for synthetic data generation, experimentation, evaluation, and delivery
• Partner with DaaS Engineering and Product teams to influence platform and product capabilities based on real-world customer needs
• Lead technical design reviews, share expertise, and provide guidance to other engineers
• Stay current with emerging synthetic data, LLM evaluation, and data curation techniques and assess their applicability to customer problems
