In this role, you will:

• Design, develop, test, and maintain batch and real‑time data pipelines, including complex or non‑routine software that meets design requirements.
• Build and operate highly available, distributed systems for data extraction, ingestion, processing, movement, storage, and access, internal and external to the business unit.
• Apply software design principles, object‑oriented design, data structures, algorithms, and distributed computing concepts, leveraging software frameworks to write simpler code.
• Work with large‑scale datasets and complex data access patterns.
• Develop software using languages such as Java, Python, Scala, and Spark.
• Apply data modeling, schema design, data validation, testing, monitoring, alerting, and performance‑tuning practices.
• Apply EG reference patterns and technology choices, and recommend alternative architectures, technologies, and programming languages where they fit better.
• Design software that is modular, maintainable, testable, observable, and cost‑efficient.
• Monitor, troubleshoot, debug, and resolve production issues within established service‑level agreements.
• Lead code reviews and help guide the evolution of technical solutions.
• Coordinate stakeholders with varied perspectives, contribute your own suggestions, and collaborate across the organization to understand dependencies and solve shared problems.
• Mentor junior engineers and participate in communities of practice.
• Identify opportunities to improve policies, processes, system efficiency, and operational practices across organizational boundaries.

Experience and Qualifications Required:

• 6+ years of relevant experience with a bachelor’s degree, 3+ years with a master’s degree, or equivalent related professional experience.
• Experience developing software in at least three programming languages.
• Experience building and maintaining more than one production data pipeline or data product (bug fixing, troubleshooting, monitoring).
• Proficiency in at least 3 data‑relevant programming languages (e.g., Java, Python, Scala, Spark), and the ability to identify their strengths and weaknesses for particular use cases.
• Hands‑on experience with large volumes of data: ingestion, batch and real‑time processing, movement, storage, and access.
• Hands‑on experience with at least one cloud technology and its data offerings.
• Understanding of databases, data structures, algorithms, object‑oriented design, data modeling, testing, monitoring, alerting, and debugging.
• Ability to design moderately complex systems, apply organizational reference patterns, and make independent technical decisions within project scope.
• Understanding of how team goals fit business needs, and ability to mentor junior engineers.
• Strong communication and collaboration skills.
