Senior Data Engineer
Senior Data Engineer
Prolific is not just another player in the AI space – we are the architects of the human data infrastructure that's reshaping the landscape of AI development. In a world where foundational AI technologies are increasingly commoditized, it's the quality and diversity of human-generated data that truly differentiates products and models.
The Role
We're looking for a Senior Data Engineer to help build scalable data solutions that serve teams across the business – from data scientists and analysts to AI engineers and product teams. You’ll contribute to both the underlying platform and the way data is used in our products, working in a modern, cloud-native environment where privacy, security, and good data practices are core to how we build.
What You’ll Bring
Technical Expertise
- 3+ years’ experience building and shipping production-grade data systems
- Strong SQL skills and proficiency in Python (or another object-oriented language, such as Java, Scala, etc.)
- Familiarity with cloud-native infrastructure, including exposure to:
- Terraform
- Kubernetes, or similar Infrastructure-as-Code (IaC) and container orchestration tools
- Experience designing data APIs or services that expose data to applications, or a keen interest in bridging analytical and operational systems
- A thoughtful approach to data quality, privacy, and security – you understand that how data is used is as important as how it’s moved
Soft Skills & Mindset
- Strong collaboration skills and ability to work across teams with differing priorities (e.g., engineers, data scientists, AI engineers, product teams)
- Pragmatic, curious mindset: comfortable keeping up with industry trends and deciding when to adopt new tools and when to stick with proven solutions
- Pipeline Management: Hands-on experience with tools like Airflow, dbt, and the ability to optimize pipelines for performance and reliability
- Quality Focus: Deep commitment to improving product quality, security, and performance through rigorous testing and code reviews
- Documentation: Meticulous attention to creating and maintaining architecture and systems documentation
- Problem-Solving: Exceptional analytical skills for troubleshooting complex data challenges
- Independence: Ability to ship medium-sized features independently, while contributing to the team’s broader objectives

- Infrastructure-as-Code (Terraform)
- Kubernetes-based deployments (e.g., Argo) to improve scalability, reliability, and self-service capabilities
- Design and implement scalable data architecture to accommodate growing data volume and complexity
- Develop data services and APIs that provide trusted data to product applications, effectively bridging analytical and operational systems
- Take ownership of data quality and observability:
- Implement monitoring, testing, and alerting to ensure data integrity
- Enable early issue detection and maintain trust in data
- Collaborate with AI engineers, data scientists, analysts, and product teams to identify data needs and design optimal solutions – prioritizing effectiveness over speed
- Enforce strong data privacy, security, and compliance practices, especially around product-facing data contexts
- Create and maintain comprehensive technical documentation (e.g., data flows, models, and systems) for knowledge sharing
