Data Engineer

Sr. Software Engineer - Data

Our Mission:

6sense's mission is to multiply what matters: growth, retention, and efficiency.  We envision a future where companies, teams and people reach their full potential.

Our People:

People are the heart and soul of 6sense. We serve with passion and purpose. We live by our Being 6sense values of Win as One Team, Stay Curious, Do The Right Thing, Own the Outcome, and Create Belonging.  Every 6sensor plays a part in defining the future of our industry-leading technology.  6sense is a place where difference-makers roll up their sleeves, take risks, act with integrity, and measure success by the value we create for our customers.  We want 6sense to be the best chapter of your career. 

About the Role 

At 6sense, data powers our AI‑first products at massive scale. We’re looking for a Senior Software Engineer – Data who can design, own, and evolve large‑scale data systems end‑to‑end, while using AI tools (prompting + vibe coding) as a force multiplier.

This is not an ML research role. AI here means leveraging LLMs to accelerate engineering velocity and improve system quality. At this level, you are expected to drive architecture, lead complex problem solving, and influence technical direction across systems.

What You’ll Do 

End-to-End System Ownership

• Design, build, and operate large-scale batch and real-time data pipelines.
• Take ownership of entire data domains (not just pipelines) including ingestion → transformation → serving layers.
• Ensure high reliability, observability, and maintainability of data systems.

System Design & Architecture

• Architect scalable, fault-tolerant data platforms handling high-throughput workloads.
• Make critical decisions on data modeling, storage formats, and compute frameworks.
• Design systems with cost efficiency, performance, and data freshness trade-offs in mind.

Technical Leadership

• Lead design discussions and review complex system architectures.
• Mentor IC3 engineers; raise engineering bar across code quality, testing, and design.
• Proactively identify and drive platform-level improvements and simplifications.

Advanced Data Engineering

• Develop and optimize high-performance SQL and distributed computations at scale.
• Work deeply with Spark, Kafka, Hive, Presto, or equivalent ecosystems. 
• Solve data consistency, deduplication, and large-scale data quality challenges.

AI-Enabled Engineering (Required)

• Use AI tools (Copilot, ChatGPT, Cursor, etc.) for:
• Accelerating development, debugging, and refactoring 
• Generating and optimizing SQL and pipelines
• Understanding large codebases and diagnosing production issues
• Demonstrate advanced prompting strategies and ability to operationalize AI safely.
• Balance speed vs correctness—validate performance, security, and correctness rigorously. 

Cross-Team Impact

• Partner with Data Science, Platform, and Backend teams to build datasets powering products. 
• Influence roadmap decisions through technical insights and trade-offs.
• Contribute to data platform standards, reusable frameworks, and best practices.

What We’re Looking For :

Experience

• 6–10 years of experience in data engineering or distributed systems

Core Skills

• Strong coding expertise in Python and/or Java 
• Deep expertise in SQL optimization on large-scale datasets 
• Hands-on experience with big data technologies (Spark, Kafka, Hive, Presto)
• Experience building systems on AWS (S3, EMR, Redshift, EC2)

Advanced Capabilities

• Proven ability to design and scale distributed systems independently
• Strong understanding of:
• Data modeling and schema evolution
• Streaming vs batch trade-offs
• Data SLAs and cost optimization
• Experience handling production-grade failures and large-scale debugging

AI Productivity

• Practical, real-world use of AI tools to improve engineering velocity 
• Ability to use AI strategically, not just tactically

Nice to Have

• Experience with NoSQL / MPP systems 
• Exposure to Docker / Kubernetes
• Experience building or supporting AI/LLM-powered systems or data pipelines 

One-Line Summary on Skills

• Python + SQL + Distributed Systems (Spark/Kafka) + AWS + System Design + AI-enabled Development

Our Benefits: 

Full-time employees can take advantage of health coverage, paid parental leave, generous paid time-off and holidays, quarterly self-care days off, and stock options. We’ll make sure you have the equipment and support you need to work and connect with your teams, at home or in one of our offices. 

We have a growth mindset culture that is represented in all that we do, from onboarding through to numerous learning and development initiatives including access to our LinkedIn Learning platform. Employee well-being is also top of mind for us. We host quarterly wellness education sessions to encourage self care and personal growth. From wellness days to ERG-hosted events, we celebrate and energize all 6sense employees and their backgrounds.
