Data Infra Tech Lead

At Lusha, we're building for Builders, we build fast & AI-first --- so we look for Builders!

By a builder, we mean someone who turns “maybe” into “done”.

The Data Group builds and maintains the core data assets that power our products, from our Company and Contact databases to our Connect and Recommendation systems. The Data Tech Lead sits at the forefront of that mission, leading engineering innovation that directly shapes the experience of our growing user base and drives the evolution of Lusha’s intelligent data services.

This role is based in Tel Aviv. We work in a hybrid model, with 3 days a week in the office.

Your impact and responsibilities:

• Leading the design and development of scalable, high-performance data workflows, including both batch pipelines and real-time data products.
• Defining, implementing, and enforcing engineering best practices related to code quality, testing, CI/CD pipelines, observability, and documentation.
• Mentoring, supporting, and growing a team of data engineers, fostering a collaborative and high-performance engineering culture.
• Identifying opportunities to create new data assets and features that expand Lusha’s product capabilities and value proposition.
• Driving architectural decision-making in areas of data modeling, storage solutions, and compute resources within cloud environments such as Databricks and Snowflake.
• Collaborating closely with cross-functional stakeholders- including Product, DevOps, and R&D - to ensure effective delivery and platform stability.
• Promoting and championing a data-driven mindset across the organization, balancing technical rigor with business context and strategic goals.
