Job description

Kaisa.io is on a mission to transform life’s most important purchases – like buying a car or a home – into exceptional customer experiences. They believe the future of customer engagement will be driven by AI, and that AI is only as powerful as the data it learns from. That’s why they’re building an intelligent voice and engagement platform that empowers marketplaces and their dealers to deliver radically more efficient and responsive buying journeys. Their systems capture millions of critical interactions across calls, forms, and messages, and they’re seeking a Senior Data Engineer to lead the charge in architecting the scalable, high-velocity data platform that turns this unique data into fuel for their next generation of AI agents and conversational intelligence products.

About the Role

As a Senior Data Engineer you’ll take ownership of their data platform, lead the design of scalable data pipelines, and drive the evolution of their data architecture. You’ll collaborate closely with Product, Engineering, and Business teams to transform raw data into actionable insights that power their products and operations.

This is a pivotal role – their data infrastructure isn’t just powering dashboards and reports; it’s foundational to the next generation of AI-driven capabilities we’re building. With intelligent agents and automation on the horizon, high-quality, well-structured data is central to our product strategy and customer experience.

You’ll also play a key role in shaping Kaisa’s overall data strategy, ensuring their platform not only meets today’s needs but also scales with future demands. From architecting robust pipelines to mentoring team members, this is a high-impact position with significant room for influence.

Who You Are

You’re a curious, hands-on data engineer with strong technical chops and a natural drive to lead. You enjoy solving messy problems with clean systems, and you care deeply about data quality, clarity, and performance. You’re confident in technical conversations, open to feedback, and motivated by working with smart, kind teammates.

To succeed in this role, you should have:

• Solid experience designing and building scalable ETL/ELT pipelines using Python and AWS services
• Hands-on experience with some or all of: Spark, AWS EMR, Redshift, Glue, MySQL
• Deep understanding of data modeling, data warehousing, and governance
• Experience leading data architecture work and evolving infrastructure based on business needs and have the ability to translate business strategy into technical roadmaps
• Strong understanding of data security, privacy regulations (e.g., GDPR), and compliance best practices to safeguard sensitive information
• Ability to define and drive data quality frameworks, including automated testing and validation processes
• Experience with real-time or streaming data processing technologies (Kafka, Kinesis, or similar)

Personal attributes that will make you thrive in this role:

• Strong collaboration skills – working closely with cross-functional teams to gather requirements and deliver solutions
• Experience mentoring other engineers and driving team best practices
• Excellent communication skills – able to share context clearly across tech and non-tech audiences

Bonus if you also bring:

• Experience contributing to data strategy and roadmap development
• Experience with infrastructure as code, containerized environments (e.g., Terraform, Kubernetes)
• A background in data-driven product development, experimentation, or analytics
