• You'll partner with stakeholders to understand data requirements, develop domain expertise, and translate business needs into effective data models and solutions.
• You'll establish and improve data quality standards, validation rules, documentation, and governance practices.
• You'll implement monitoring and observability practices to identify bottlenecks, improve performance, and strengthen platform reliability.
• You'll provide technical leadership on architecture, scalability, reliability, monitoring, integration, and extensibility.
• You'll lead and contribute to code reviews, helping maintain high standards for code quality, performance, and maintainability.
• You'll mentor junior engineers and support a culture of continuous learning and technical excellence.
• You'll take ownership of production issues, including troubleshooting, root-cause analysis, escalation, and long-term resolution.
• You'll independently lead multiple features and projects, coordinate work across engineers, and keep stakeholders informed of progress, risks, and dependencies.
• You'll help evolve engineering tools, platforms, and practices and encourage adoption of better ways of working.
• You'll look for practical ways to use AI tools to improve engineering productivity, analysis, documentation, and problem-solving.

The right fit looks like this

You're a hands-on data engineer who enjoys solving complex technical problems and building systems that others depend on. You combine strong technical depth with a practical understanding of business needs and know how to turn ambiguous requirements into scalable solutions.

Our AI Mindset

We build with AI. We lead with judgment.

AI isn't a feature here. It's how we work.

We're excited about what AI makes possible, and we're looking for people who share that curiosity. You don't need to be an expert. You need to be open to experimenting, willing to learn, and able to apply new tools in ways that actually move the needle.
