Our industry-leading portfolio unlocks human and machine potential to drive business growth, innovation, and sustainable success. BMC does this in a simple and optimized way by connecting people, systems, and data that power the world’s largest organizations so they can seize a competitive advantage.

We're looking for a Senior Data Scientistto join our AMI group. This hands-on role combines Machine Learning, statistical modeling, Generative AI, RAG, model evaluation, and fine-tuning for enterprise AI applications. AMI supports commercial AI providers and on-premises models, with agents, MCP tools, and A2A interoperability delivered in partnership with AI Engineering.

About the Role:

You will independently design, develop, evaluate, and operationalize complex AI/ML solutions. You will contribute hands-on technical expertise, apply rigorous experimentation and MLOps/LLMOps practices, improve modeling and evaluation approaches within assigned initiatives, and mentor other Data Scientists.

You will be a part of the AI Migration team, responsible for building tools that help customers transition from competitor products to BMC solutions. You'll work at the intersection of software engineering and AI, combining code-based conversion with AI-assisted processing to tackle migration challenges. Your work will help reduce manual effort and enable services to deliver accurate, timely customer migrations

Key Responsibilities:

Machine Learning & Applied Data Science

• Apply classification, regression, ranking, forecasting, clustering, and anomaly detection to enterprise AI and agentic use cases.
• Develop and evaluate intent classification, semantic matching, agent/skill/tool ranking, and model-routing techniques; compare learned approaches with rules, embeddings, and LLM-based baselines.
• Use statistical modeling to estimate execution latency, token demand, inference costs, workload trends, and resource requirements.

Foundation Models, Prompting & Context Engineering

• Evaluate commercial API and self-hosted open-weight models for accuracy, reasoning, instruction adherence, structured outputs, latency, throughput, and total cost.

• Curate instruction datasets and holdout evaluations; apply SFT, LoRA, QLoRA, or comparable methods.
• Measure gains over base-model and prompting/RAG baselines, including generalization, regressions, data leakage, and operating costs.
• Collaborate on the packaging and validation of fine-tuned model artifacts and adapters.

Agentic AI, MCP & A2A

• Apply modeling and evaluation expertise to intent routing, agent/skill discovery, MCP tool selection, workflow selection, and planning effectiveness.
• Evaluate task completion, tool-call correctness, argument extraction, delegation quality, and recovery from failures.
• Work with AI Engineering on agentic frameworks and understand MCP tool schemas and A2A Agent Cards, skills, and task delegation.
• Contribute decision models and quality signals without owning agent runtime, MCP server, or A2A protocol implementation.

AI Evaluation & Experimentation

• Design golden datasets, holdout sets, human review protocols, LLM-as-judge calibration, and statistical comparison methods.
• Automate evaluations and regression checks for prompts, foundation models, RAG, fine-tuned models, routing, and agents.
• Define measurable quality thresholds for accuracy, relevance, groundedness, instruction following, task completion, and cost/performance.
• Investigate regressions and use evidence to guide model, prompt, retrieval, and routing decisions.
• Implement and maintain reproducible experimentation, model evaluation, and lifecycle workflows for assigned AI/ML initiatives, including automated validation and production readiness checks.

MLOps, LLMOps & Model Lifecycle

• Apply reproducible experiment tracking across datasets, code, model versions, hyperparameters, prompts, retrieval configurations, metrics, and artifacts.
• Develop and maintain automated training, fine-tuning, benchmarking, and evaluation pipelines, with model registry and artifact traceability.
• Define and integrate quality gates, regression tests, and model/prompt/RAG release-readiness criteria with engineering teams.
• Analyze production quality and drift signals, agent routing accuracy, latency, throughput, and token usage; recommend remediation.
• Collaborate with engineering on packaging, deployment handoffs, observability, rollback criteria, and ongoing model lifecycle management.

Technical Leadership & Collaboration

• Independently lead complex Data Science initiatives from problem formulation through model development, evaluation, and production handoff.
• Make technical decisions within assigned initiatives, balancing model quality, performance, cost, and delivery requirements.
• Improve reusable modeling, benchmarking, experimentation, and MLOps/LLMOps practices within assigned initiatives.
• Collaborate with AI Engineering, AI Quality, Platform Engineering, Product Management, and domain experts.
• Translate business requirements into measurable AI and ML objectives.
• Mentor junior and mid-level Data Scientists and contribute to technical reviews.
• Communicate complex AI and ML concepts clearly to technical and non-technical stakeholders.
