Lead LargeScale Data Systems :

• Design, build, and evolve highthroughput batch and streaming data pipelines that process billions of records.
• Own core datasets that power product features, analytics, and ML systems.
• Build systems that handle enrichment, deduplication, identity resolution, and confidence scoring at scale.

Drive Architecture & Technical Direction :

• Define longterm architecture for foundational data platforms.
• Lead complex, multiquarter initiatives such as platform migrations, major refactors, and new data foundations.
• Balance data correctness, freshness, cost, and performance in realworld production systems.

Ensure Reliability & Data Quality :

• Own SLAs/SLOs for data freshness, accuracy, and completeness.
• Design data quality frameworks, reconciliation mechanisms, and observability for critical pipelines.
• Lead rootcause analysis and long term fixes for production issues.

Collaborate Across the Company :

• Partner with Product, Analytics, Data Science, Platform, and GTM teams to translate business needs into scalable data solutions.
• Act as a technical point of contact for third party data integrations and vendors.

Raise the Engineering Bar :

• Mentor senior engineers and influence technical standards across the org.
• Lead by example in design reviews, operational ownership, and incident response.
• Help shape engineering best practices around scalability, reliability, and maintainability.
• Leverage generative AI and AI coding tools to accelerate developer productivity, engineering workflows, and automation of repetitive tasks

What We're Looking For :

Experience :

• 10+ years of experience building backend or data intensive systems.
• Proven ownership of mission critical data platforms in production.
• Experience operating at Senior or Staff engineer scope.
• Understanding of AI-native software development practices, including automated code generation, AI-driven testing, and human-in-the-loop review systems
• Proven ability to adopt and drive modern engineering paradigms, particularly integrating AI into development workflows to improve productivity, quality, and delivery speed

Technical Skills :

• Strong programming skills in Python and SQL.
• Deep experience with bigdata and streaming systems such as Spark, Kafka, Flink, Hive, Trino/Presto.
• Solid understanding of distributed systems, data consistency, and fault tolerance.
• Handson experience with AWS based data infrastructure.

Engineering Mindset :

• Comfortable working in ambiguity and making high impact technical decisions.
• Strong intuition for data modeling, system design, and long term maintainability.
• Ability to influence teams without formal authority.

AIEnabled Development :

• Experience using AI tools (e.g., Copilot, ChatGPT, Cursor) to improve productivity in design, coding, and debugging.
• Strong judgment on validating correctness and performance.

Nice to Have :

• Experience with company or people data, identity graphs, or enrichment pipelines.
• Exposure to data privacy, compliance, or governance at scale.
• Experience supporting AI/ML driven product features.

Why This Role Matters :

The systems you build will directly impact:

• Product accuracy and customer trust
• GTM targeting and revenue outcomes
• The scalability of 6sense's AIdriven platform

You won't just ship features, you'll shape the foundation.

OneLine Summary :

• Own and evolve large scale, business critical data platforms that power 6sense's AIdriven products.
