Data Engineering Lead - Data Quality Systems

Accountabilities

• Architect and build continuous data-quality systems, including verification, sampling, scoring, and reconciliation pipelines operating across billions of company and people records.
• Design reusable frameworks, abstractions, and technical specifications that allow engineers to create quality checks efficiently, reliably, and consistently.
• Build evaluation harnesses for LLM-powered validation and extraction, including labeled evaluation sets, precision/recall measurement, judge calibration, prompt versioning, and model-drift detection.
• Establish pre- and post-production release gates that identify and prevent poor-quality data from reaching customers, supported by effective failure analysis and triage tooling.
• Investigate large-scale data-quality incidents, identify root causes, implement corrective solutions, and convert recurring failures into permanent automated checks.
• Lead a team of 3–5 Applied AI Engineers through technical direction, code reviews, pairing, mentoring, and development of end-to-end ownership.
• Set and maintain a high technical standard while remaining approximately 80% hands-on in engineering and architecture.
• Apply sound judgment when choosing between deterministic rules and LLM-based validation, using structured rules where appropriate and semantic models where they add value.
• Operate LLM-based quality systems as production infrastructure, with appropriate evaluation, traceability, prompt and model versioning, cost controls, and performance monitoring.
• Contribute to an AI-native engineering culture based on agentic development, automated evaluation, logged traces, AI-assisted review, and reusable workflow specifications.
• Establish scalable engineering practices in a lean environment characterized by high ownership, minimal process overhead, and frequent production releases.

Requirements

• 7+ years of experience building production-grade data systems in business-critical environments, including systems that operate reliably at significant scale.
• Demonstrated experience working with billions of data rows and designing quality controls that remain performant and dependable at large scale.
• Proven track record of building data-quality systems and frameworks, such as validation engines, anomaly detection, scoring systems, sampling strategies, or reconciliation mechanisms against trusted data.
• Experience designing evaluation or test harnesses that are used by other engineers and can support systematic measurement of quality.
• Previous experience providing technical leadership to engineers, including code reviews, technical direction, pairing, mentoring, and hands-on delivery.
• Strong Python development skills and advanced SQL expertise, with an understanding of performance optimization, concurrency, and large-scale data transformations.
• Practical experience operating LLMs as production systems, including evaluation sets, versioned prompts, trace logging, cost controls, and debugging model judges against precision and recall.
• Proven experience using agentic development environments such as Claude Code, Cursor, or equivalent tools to build and ship production software.
• Strong technical judgment regarding when to use deterministic rules versus LLM-based semantic evaluation, with the ability to clearly justify architectural decisions.
• Experience with B2B data, including firmographics, people data, entity resolution, or registry matching across multiple markets, is highly valued.
• Familiarity with cloud data platforms such as Snowflake, Databricks, or Redshift, together with AWS-based pipeline deployment, is advantageous.
• Production-scale experience with Airflow or an equivalent orchestration platform is a plus.
• Knowledge of vector databases, embeddings, retrieval patterns, matching, or deduplication is desirable.
• Startup or scaleup experience, particularly in environments where engineering standards and frameworks had to be established from the ground up, is highly valued.
• Strong ownership, judgment, adaptability, and communication skills suited to a fast-moving, autonomous, and highly collaborative engineering environment.

Benefits

• Fully remote position based in India.
• Competitive base salary aligned with the seniority and technical scope of the role.
• Meaningful equity participation and the opportunity to share in the organization's long-term growth.
• Significant technical ownership over a critical data-quality and trust layer.
• Greenfield engineering opportunities to define frameworks, standards, validators, evaluation systems, and release gates.
• Exposure to frontier engineering challenges involving LLM evaluation, model drift, agentic development, anomaly detection, and large-scale data quality.
• Opportunity to lead a small, senior engineering team while remaining deeply hands-on technically.
• Lean, high-autonomy environment with minimal management layers and strong end-to-end ownership.
• AI-native engineering practices, with agentic development, evaluations, traces, and AI-powered review integrated into everyday workflows.
• Fast release cycles and the opportunity to make visible contributions across multiple international markets.
• Equal-opportunity environment that values diverse perspectives and inclusive collaboration.
