Filigran builds cybersecurity software and open-source security tools, with products spanning threat intelligence and adversarial validation. The company operates across EMEA, North America, and APJ, with its software currently protecting thousands of organizations worldwide. Alongside its commercial offerings, Filigran publishes free, community-driven tools as a core part of its identity and participation in the open-source movement.
Engineering at Filigran is organized into small, high-impact teams where advanced technical skills are expected. The company places deliberate emphasis on code quality, thoughtful review practices, and minimizing technical debt - prioritizing craftsmanship over rapid expansion. Diverse perspectives are considered a direct input into product decisions, and engineers carry meaningful ownership over what they build.
Filigran operates as a remote-first, async-first organization. Clear written communication and ownership take precedence over face time or micromanagement. The company describes its culture as one where serious professional craft and genuine enjoyment of work coexist - oriented around doing meaningful work rather than performing busyness.
