About The Position

BMC empowers nearly 80% of the Forbes Global 100 to accelerate business value, faster than humanly possible. 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.
The IZOT product line includes BMC’s Intelligent Z Optimization & Transformation products, which help the world’s largest companies to monitor and manage their mainframe systems. The modernization of mainframe is the beating heart of our product line, and we achieve this goal by developing products that improve the developer experience, the mainframe integration, the speed of application development, the quality of the code and the applications’ security, while reducing operational costs and risks. We acquired several companies along the way, and we continue to grow, innovate, and perfect our solutions on an ongoing basis.
About the Role
You build the systems that tell us whether our agentic AI is good enough to ship: evaluation frameworks, golden datasets, and rubrics; automated eval harnesses in CI; and drive down failure modes such as hallucination, drift, and unsafe or non-repeatable output. You are the reason customers can trust what our agents produce.
At this level you independently own well-scoped work from definition through delivery.
Scope at this level: Independently owns well-scoped eval work for a feature/team from definition through delivery.
Organizational impact expected: Improves outcomes for one team or project.

Requirements

• Bachelor's or master's in computer science, AI, or related field (or equivalent experience).
• Experience with Generative AI / LLM applications or AI/ML systems and quality/evaluation frameworks (depth scales with level).
• Understanding of LLM/RAG/agentic failure modes; vector DBs and embedding retrieval as level requires.
• Python; building eval sets, rubrics, automated scoring; CI/CD integration.
• LLM observability/tracing (e.g. Langfuse, OTel) and analytics (OpenSearch or similar) as level requires.
• Rigorous, data-driven mindset; collaboration across DS, engineering, and product.
• Evidence of owning an eval suite that influenced a release decision.
• Builds consistent rubrics/datasets — not one-off manual spot checks only.
• Works independently on scoped quality problems.
• Past experience: Owned a defined evaluation suite or quality workflow for an AI feature and partnered with stakeholders on “good enough.”
• Delivery evidence: Decision-ready quality report; evals integrated into a release or CI path for one product/team.
• Shared expectation: Independently owns well-scoped work from definition through delivery.

Nice To Haves

• Ragas, DeepEval, promptfoo, or similar eval frameworks.
• AI safety/governance; enterprise/regulated environments.
• OpenShift/AWS; performance/load/reliability testing of AI apps.
• MLOps; open-weight models/local serving; MCP; Agile/Atlassian

Responsibilities

• Define and implement evaluation strategies and frameworks for Generative AI, RAG, and agentic AI applications.
• Create golden datasets, rubrics, and scoring methods (including LLM-as-a-judge) so quality is measured consistently.
• Apply statistical sampling, repeated trials, judge calibration, dataset versioning, and anti-contamination practices.
• Stand up automated evaluation harnesses in CI so model/prompt/agent changes are re-scored before ship.
• Define quality metrics and release gates for customer-ready vs prototype.
• Design testing strategies for multi-agent workflows and AI systems using tools, APIs, MCP, and enterprise apps; Playwright where relevant.
• Evaluate end-to-end agent behaviour (planning, tool use, response generation, task completion).
• Identify failure modes using observability/tracing; recommend reliability improvements.
• Close the loop from evaluation results into model/prompt improvements with DS and AI Engineering.
• Champion Responsible-AI and human-in-the-loop principles; contribute to governance and model validation.

Benefits

• The annual base salary range represents the low and high end of the BMC salary range for this position. Actual salaries depend on a wide range of factors that are considered in making compensation decisions, including but not limited to skill sets; experience and training, licensure, and certifications; and other business and organizational needs.
• The range listed is just one component of BMC's employee compensation package. Other rewards may include a variable plan and country specific benefits.
