How We Work We move quickly, collaborate across disciplines, and expect leaders to take ownership of both technical outcomes and team development. Our Team Leads remain close to the architecture and the work while creating the clarity, standards, and environment their teams need to succeed. We care about reliability and engineering excellence, but we also expect infrastructure decisions to support measurable product impact, operational efficiency, and sustainable scale. This is a hybrid role based in our Modi’in office, with three days a week in the office. If you’re looking for a leadership role where you can shape both a critical data platform and the team building it, we’d love to hear from you.
