Backend Developer, Research Group (B2B contract)

Location: Warsaw, EMEA

Description

About the Position

Ox Security is the pioneer of Active ASPM, purpose-built to secure the modern software supply chain in the age of AI. While traditional tools overwhelm teams with endless alerts, Ox cuts through the noise to identify the critical 5% of risks – those that are truly reachable and exploitable. From GenAI-generated code to cloud runtime, we provide developers and security teams with the visibility and automation needed to ship secure software, faster.

We’re looking for a strong Backend Engineer to join our Security Research group and build the systems that power our open source intelligence and research efforts.

This is a high-impact individual contributor role where you’ll work closely with researchers, turning prototypes, scrapers, and data pipelines into scalable, production-grade systems. You’ll own projects end-to-end –  from design through deployment – with a high level of autonomy.

Requirements:

What You’ll Be Doing

  • Design, build, and maintain systems that collect open source intelligence at scale
  • Build and own APIs that enable other teams to consume and leverage this data
  • Take research prototypes and turn them into robust, observable production services
  • Define and evolve architecture and data pipelines for large-scale data processing
  • Work closely with researchers to translate ideas into scalable engineering solutions
  • Own projects end-to-end, from scoping and design to deployment and monitoring
