Data Engineer

In short

Senior Data Engineer role leading design and implementation of an on-premises, self-service data orchestration platform, with strong focus on data quality, governance, and CI/CD for data pipelines. Involves close collaboration with ML/AI teams on batch and real-time feature engineering pipelines, plus mentoring junior engineers. Requires 5+ years of data engineering experience (2+ on enterprise-scale platforms), SQL and Python proficiency, stream processing and containerization experience, and a Bachelor's degree in a related technical field.

About the Role
We're seeking a talented Senior Data Engineer to join our team in a cross-cutting role that will help define and implement our next-generation data platform. In this pivotal position, you'll lead the design and implementation of scalable, self-service data pipelines with a strong emphasis on data quality and governance. This is an opportunity to shape our data engineering practice from the ground up, working directly with key stakeholders to build mission-critical ML and AI data workflows.
Key Responsibilities
•Design, build, and maintain our on-premises data orchestration platform using the best-in-breed open-source tools
•Create self-service capabilities that empower teams across the organization to build and deploy data pipelines without extensive engineering support
•Implement robust data quality testing frameworks that ensure data integrity throughout the entire data lifecycle
•Establish data engineering best practices, including version control, CI/CD for data pipelines, and automated testing
•Collaborate with ML/AI teams to build scalable feature engineering pipelines that support both batch and real-time data processing
•Develop reusable patterns for common data integration scenarios that can be leveraged across the organization
•Work closely with infrastructure teams to optimize our Kubernetes-based data platform for performance and reliability
•Mentor junior engineers and advocate for engineering excellence in data practices
Qualifications
•At least a Bachelor's degree in Computer Science, Computer Engineering, Data Science, Mathematics, Engineering, or related disciplines
•5+ years of professional experience in data engineering, with at least 2 years working on enterprise-scale data platforms
•Deep expertise with orchestrating workflows, performance optimization, and operational management
•Strong understanding of data transformation techniques, including experience with testing frameworks and deployment strategies
•Experience with stream processing frameworks and technologies
•Proficiency with SQL and Python for data transformation and pipeline development
•Familiarity with containerized application deployment
•Experience implementing data quality frameworks and automated testing for data pipelines
•Ability to work cross-functionally with data scientists, ML engineers, and business stakeholders
Preferred Qualifications
•Experience with self-hosted data orchestration platforms (rather than managed services)
•Background in implementing data contracts or schema governance
•Knowledge of ML/AI data pipeline requirements and feature engineering
•Experience with real-time data processing and streaming architectures
•Familiarity with data modeling and warehouse design principles
•Prior experience in a technical leadership role
We emphasize building systems that are maintainable, scalable, and focused on enabling self-service data access while maintaining high standards for data quality and governance.
About You
The ideal candidate is a problem-solver who enjoys working on complex data systems and is passionate about data quality. You thrive in collaborative environments but can also work independently to deliver solutions. You're comfortable working directly with technical and non-technical stakeholders and can communicate complex technical concepts clearly. Most importantly, you're excited about creating systems that empower others to work with data efficiently and confidently.
