Note: The job is a remote job and is open to candidates in USA. Filigran is a global, fully remote company building open-source cybersecurity solutions, including OpenCTI, to help organizations anticipate and manage cyber threats. The Staff/Tech Lead Software Engineer will lead technical collaboration with a key external partner, contribute to the OpenCTI codebase, ensure the quality of partner contributions, and provide technical guidance and mentoring to internal and partner engineers.
Responsibilities
- Act as technical relay and enabler for the partnership — not just a solo contributor
- Contribute directly to key parts of the codebase, especially where partner and core work intersect
- Facilitate technical refinement sessions and design reviews with partner engineers
- Supervise, challenge, and elevate the technical quality of contributions coming from the partnership
- Promote OpenCTI's best practices, code quality, and performance standards externally and internally
- Coach engineers (internal and partner-side) via pair programming, code reviews, and structured feedback
- Collaborate with EMs/POs on task sizing, scope alignment, and roadmap planning for partner-related work
- Proactively report progress, risks, and technical alignment issues to the Director of Engineering and Product Manager
Skills
- Strong experience with TypeScript
- Hands-on experience with our technical stack: NodeJS, React, GraphQL, Elasticsearch, Redis
- Strong hands-on experience leveraging AI tools (e.g. Copilot, Cursor, LLM-based agents) to accelerate and improve software development
- Autonomy and ownership — proactive, self-directed, with strong reporting/alerting habits
- 8+ years in Software Engineering with a track record of reliable, iterative delivery
- Comfortable in a full-remote, async-first environment, with colleagues from multiple time zones
- Architectural force of proposal — pragmatic trade-offs, stakeholder alignment
- Strong communication and diplomacy skills — this role requires influencing an external partner's engineering practices without formal authority over them
- Cybersecurity / CTI (Cyber Threat Intelligence) experience is not a requirement but definitely a strong plus
- Plus: experience working with external stakeholders / partners / vendors
- Plus: Open-source experience — contributing to, maintaining, or leading work on open-source projects
Benefits
- Competitive pay + equity - everyone shares in our success
- Remote-first, flexible, and balanced - work that fits your life
- Your setup, your choice - pick the gear that works for you
- Twice-a-year gatherings - we meet in person for regional and global offsites to connect, collaborate, and strengthen our culture beyond the screen
