Position Summary As a Senior Data Engineer, you will design, build, and continuously improve critical data processing and analytics pipelines. You will solve complex technical problems to enhance platform reliability, resiliency, and scalability, and you will deliver dashboards and reporting solutions that enable stakeholders to analyze performance and make data-informed decisions.

About the Role We are seeking a self-directed engineer who thrives with autonomy and can drive long-term projects to completion. You are detail- and quality-oriented, and motivated by the opportunity to deliver measurable business impact through data.

Key Responsibilities Translate business requirements into scalable data and analytics architectures with a product-focused mindset.

Partner with data engineers, data scientists, product managers, and other stakeholders to understand needs and promote best practices. Identify business challenges and improvement opportunities; apply data analysis and data mining to develop strategic and tactical recommendations. Support analytics by delivering insights on product usage, campaign performance, funnel metrics, segmentation, conversion, and revenue growth. Produce ad-hoc analyses, long-term projects, reports, and dashboards to uncover insights and measure progress against key initiatives. Work closely with business stakeholders to define, track, and maintain focus on critical metrics and KPIs. Collaborate cross-functionally to gather requirements and align on delivery. Deliver presentations that distill complex problems into clear insights for technical and non-technical audiences. Create dashboards that enable stakeholders to interact with data and perform self-serve analysis.
