The Principal Software Engineer for Copilot Evals joins the Customer and Analytics Driven Evals Team to architect and build a production system for a customer-grounded quality loop. This role involves designing scalable services and pipelines to capture customer evidence, prioritize triage, and automate evaluation assets for Copilot. You will connect heterogeneous data sources, AI agents, evaluation infrastructure, RLE platforms, model telemetry, and human review into a reliable end-to-end system. Key responsibilities include establishing data contracts, developing quality-attribution workflows, and creating observability benchmarks for pipeline health. The position requires proficiency in C, C++, C#, Java, JavaScript, or Python. You will solve the technical challenge of shifting from manual signals to an automated, agentic system that identifies customer scenarios and turns failures into reusable product and model improvements.
What does a Software Engineer earn?
Median $197400 from 2576 postings across 150 companies.
Architect and own the end-to-end technical execution for the customer-signal and evaluation system.
Create scalable services and pipelines for automated grounding-data generation, intent classification, and loss-pattern detection.
Automate recurring evaluation execution and quality gates, including scheduling, versioning, and result publication.
Establish data contracts and extensible schemas for customer signals, workflows, rubrics, and regression assets.
Develop quality-attribution workflows that combine automated diagnosis with human review to route losses to owners.
Create observability and benchmarks for pipeline health, agent behavior, data quality, and operational reliability.
Design safe human-in-the-loop gates for ambiguous data, sensitive evidence, and consequential quality decisions.
Mentor engineers and raise engineering quality through clear interfaces, testing, security, and technical documentation.
What we're looking for
Bachelor's Degree in Computer Science or related technical field and 6+ years of technical engineering experience with coding in languages like C, C++, C#, Java, JavaScript, or Python (or equivalent experience).
Extensive experience designing and delivering large-scale distributed systems, data platforms, developer platforms, or AI infrastructure in production (preferred).
Practical exposure to large language model technologies, agent systems, or AI/ML platforms (preferred).
Demonstrated principal-level technical leadership across teams and organizational boundaries (preferred).
Solid understanding of security, privacy, data governance, and responsible engineering for sensitive data (preferred).
Experience building AI/ML platforms, LLM or agent systems, evaluation infrastructure, experimentation systems, or model pipelines (preferred).
Experience with retrieval, tool-using agents, prompt and rubric management, human-in-the-loop systems, or automated diagnosis (preferred).
Experience building data and workflow platforms that combine batch, streaming, unstructured, and human-generated inputs (preferred).
