About the Role : 

This is a senior individual contributor role for engineers who enjoy owning complex systems end‑to‑end, influencing technical direction across teams, and solving problems where correctness, scale, and reliability really matter. You’ll work on problems that don’t have obvious answers and your decisions will shape how data flows through 6sense for years to come.

What will you own: :

Lead Large‑Scale Data Systems :

  • Design, build, and evolve high‑throughput 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 long‑term architecture for foundational data platforms.
  • Lead complex, multi‑quarter initiatives such as platform migrations, major refactors, and new data foundations.
  • Balance data correctness, freshness, cost, and performance in real‑world 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 root‑cause 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 big‑data and streaming systems such as Spark, Kafka, Flink, Hive, Trino/Presto.
  • Solid understanding of distributed systems, data consistency, and fault tolerance.
  • Hands‑on 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.

AI‑Enabled 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 AI‑driven platform

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

One‑Line Summary :

  • Own and evolve large scale, business critical data platforms that power 6sense’s AI‑driven products.

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.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
