Get to Know Us

Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and fix and verify exploitable attack vectors before criminals exploit them.

Design and evolve warehouse schemas and data models. Build observability into pipelines and platform components. Drive work across producer and consumer teams, communicate clearly, and own outcomes end to end.

What You’ll Bring

Strong software engineering craft: clean, correct, maintainable code with solid data-structure and problem-solving fundamentals. Deep understanding of distributed systems and data architecture: pipeline and platform design, batch vs. streaming, CDC, event contracts, multi-tenant and multi-region trade-offs, reprocessing, and observability.
