Senior Data Engineer

• Design, build, optimize, and maintain data pipelines that ingest structured and semi-structured data, in real time and batch, into Wawa's Raw, Refined, and Data Product layers, ensuring they are scalable, repeatable, secure, and serve users across the company.

• Solve moderately complex data problems, translate business needs into technical requirements and designs, and contribute to end-to-end solution designs for complex work.

• Apply data modeling standards across business intelligence tools, design data structures for moderately complex solutions, and assess the suitability and quality of candidate data sets.

• Build and deliver data products that meet their documented quality SLAs, lineage, and ownership requirements.

• Build and maintain Snowflake-native transformation pipelines (SQL, stored procedures, tasks, streams, dynamic tables) with version control, testing, and CI/CD-gated deployment.

• Optimize warehouse cost and performance through query tuning, warehouse sizing, and consumption monitoring.

• Partner with Data Governance on certification reviews, quality remediation, and policy adherence for production datasets.

• Validate data received from upstream systems against defined quality rules, and produce a preliminary root-cause summary when it fails.

• Collaborate with the Analytics and Data Science teams to build tested, reliable data services that enable self-service and keep solutions consistent.

• Follow security standards for all data and tools introduced to the team.

• Contribute to technical direction by participating in design reviews, mentoring junior engineers, and suggesting improvements to development and system standards. Support the investigation and resolution of production data issues.

• Work with the Lead Data Engineer to balance business requirements with technical feasibility on new projects.

• Use Wawa's AI coding harness and its curated skills as the default way of working: direct agents to draft pipelines, stored procedures, data models, and tests, rather than hand-writing every artifact from scratch.

• Review, correct, and own agent-produced code and designs to the same standard as own work.

• Write precise specifications, prompts, and acceptance criteria that let an agent produce correct, standards-compliant work, and judge when a task is better done by hand.

• Verify agent output against Wawa's data architecture standards, conformance rules, and review gates before it advances to production.

• Surface recurring engineering patterns to the platform team so they can be codified into reusable agent skills.

• Handle multiple priorities simultaneously.

• Work collaboratively with cross-functional teams and build strong, trusting relationships with business partners.

• Excellent communication skills.

• Passion for innovation and a “can do” attitude in a fast-paced, team environment.

• Read code critically and specify work precisely enough to direct both people and AI coding agents.

• Help maintain data strategy standards across the data team's work.

• Bachelor's degree in Computer Science/Engineering preferred.

• 5+ years of database and data integration experience.

• 3+ years implementing data models (logical, physical, and dimensional), including entity relationship modeling and exposure to data warehouse design.

• 3+ years developing Enterprise Data & Analytics solutions on a modern cloud data platform, Snowflake required.

• Strong knowledge of Python and SQL; experience implementing data solutions with open-source technologies.

• Hands-on experience building Snowflake-native transformation pipelines using SQL, stored procedures, tasks, streams, and dynamic tables, in an AWS-hosted cloud environment.

• Experience operating Snowflake at scale: warehouse sizing, cost monitoring, query optimization, and access control.

• Experience implementing a range of data pipeline patterns and strategies.

• Strong knowledge of data security principles.

• Proven track record working with interrelated systems and bringing that data together on enterprise platforms.

• Familiarity with data observability and quality tooling (e.g., Monte Carlo, Great Expectations, Snowflake data quality monitors) and applying it to certification SLAs.

• Demonstrated ability to review code critically, catching defects, applying standards, and giving actionable feedback. This judgment is central to the role.

• Experience working in an AI-augmented or agent-assisted development environment, or clear aptitude for one. Comfort directing AI coding agents, reviewing their output critically, and remaining accountable for what ships.
