Senior Data Engineer

Senior Data Engineer

About the Role

We're looking for a Staff Data Engineer to shape the future of our data platform. You'll architect scalable systems, set technical direction, and build the frameworks that enable our data organization to operate at scale. This is a high-leverage role where your work multiplies the effectiveness of the entire team.

What You'll Do

Platform Architecture & Strategy

Own the technical roadmap for our data platform, making architectural decisions that balance scalability, cost, and maintainability

Evaluate and champion new technologies and tools, leading adoption across the organization

Design systems for terabyte-scale data processing with a focus on performance and cost optimization

Establish data engineering standards, patterns, and best practices that elevate team quality

Model infrastructure costs and drive efficiency initiatives across Snowflake and cloud platforms

Advanced Technical Work

Design and build scalable infrastructure for AI/ML workloads, including model training pipelines, feature engineering systems, and AI agent platforms

Build reusable frameworks and internal platforms that abstract complexity for other engineers

Design complex data models for critical business domains, balancing normalization, performance, and usability

Architect real-time/streaming data infrastructure for low-latency use cases

Engineer solutions for large-dataset performance challenges (Snowflake clustering, micro-partitioning, query optimization)

Create sophisticated data-contract validators and schema evolution frameworks

Develop profiling and drift detection systems that ensure data quality at scale

Technical Leadership

Conduct design reviews and provide architectural guidance for major initiatives

Lead incident response for critical data systems and drive blameless post-mortems

Define SLAs and reliability standards for data products

Mentor and upskill data engineers through pairing, code reviews, and technical discussions

Lead cross-functional projects with analytics, data science, and product teams

Operational Excellence

Build data observability platforms with intelligent alerting and monitoring

Perform capacity planning and scalability analysis for the entire data stack

Benchmark performance across infrastructure to identify optimization opportunities

Design self-service tools that enable analytics engineers and analysts to work independently

What You Bring

Technical Depth

Deep expertise with modern data warehouses (Snowflake strongly preferred) including advanced optimization techniques

Strong foundations in distributed systems, data structures, and algorithms

Production experience building high-volume data pipelines and ETL/ELT systems

Proficiency in Python/SQL and orchestration tools (Airflow, dbt, or similar)

Experience with cloud platforms (AWS/GCP) and infrastructure-as-code

Strategic Thinking

Track record of making architectural decisions with long-term impact

Ability to evaluate tradeoffs between competing approaches

Experience balancing technical excellence with business pragmatism

Proven ability to drive technical strategy across an organization

Leadership & Communication

History of mentoring engineers and raising team capabilities

Excellent written and verbal communication for technical and non-technical audiences

Ability to build consensus and influence without direct authority

Experience leading projects across multiple teams

Bonus Points

Experience with streaming systems (Kafka, Flink, etc.)

Data mesh or domain-oriented architecture implementation

Open source contributions or technical writing

Background in analytics engineering or data modeling

You'll Thrive Here If

You think in systems and frameworks, not just individual solutions

You're energized by making other engineers more effective

You balance perfectionism with pragmatic delivery

You're comfortable with ambiguity and defining your own projects

You care deeply about code quality, documentation, and operational excellence
