Staff / Tech Lead Software Engineer - OpenCTI

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff / Tech Lead Software Engineer - OpenCTI based in the United States (East Coast, fully remote).

This is a high-impact technical leadership role focused on strengthening collaboration around an open-source cybersecurity platform.

You will serve as the technical anchor for a key external engineering partner contributing directly to the core project.

The role combines hands-on software engineering with architecture, technical refinement, code quality, and mentorship.

You will influence engineering practices across organizational boundaries, without relying on formal authority.

You will also help align partner contributions with internal architecture, product priorities, and long-term technical standards.

Working in a fully remote, async-first environment, you will collaborate with engineers and technical leaders across multiple time zones.

The position offers significant autonomy and the opportunity to shape both the product and the way teams build it.

Accountabilities:

• Own the technical relationship with a key external engineering partner, acting as the primary technical relay and ensuring collaboration remains productive, aligned, and focused on high-quality outcomes.
• Participate early in technical refinement, architecture, and design discussions for partner-driven features, helping clarify requirements, identify trade-offs, and establish pragmatic implementation approaches.
• Guide partner engineers on the platform's architecture, coding standards, development practices, performance expectations, and maintainability principles.
• Review, challenge, and elevate external contributions before they are integrated into the core codebase, ensuring consistency, reliability, quality, and long-term maintainability.
• Contribute hands-on to critical areas of the codebase, particularly where external partner work intersects with core engineering initiatives.
• Facilitate technical refinement sessions, design reviews, pair programming, code reviews, and structured feedback sessions with both internal and partner-side engineers.
• Promote strong engineering practices and continuously improve development quality, performance, and consistency across teams.
• Collaborate with Engineering Managers and Product Owners/Managers on task sizing, scope definition, roadmap planning, iteration, and milestone alignment for partner-related initiatives.
• Serve as a bridge between the external engineering team and internal technical leadership, ensuring contributions remain aligned with architecture, product priorities, and engineering standards.
• Proactively identify risks, blockers, dependencies, and technical alignment issues, providing clear and structured reporting to engineering and product leadership.

Requirements

• 8+ years of professional software engineering experience, with a strong record of reliable, iterative delivery and the ability to operate effectively at staff or technical-lead level.
• Strong hands-on TypeScript experience, combined with practical knowledge of Node.js, React, GraphQL, Elasticsearch, and Redis.
• Demonstrated ability to contribute to software architecture and make pragmatic technical trade-offs while balancing scalability, maintainability, delivery speed, and stakeholder needs.
• Strong hands-on experience using AI-powered development tools such as GitHub Copilot, Cursor, or LLM-based coding agents to accelerate and improve software engineering workflows.
• Strong autonomy and ownership, with a proactive approach to identifying issues, unblocking work, communicating risks, and keeping stakeholders informed.
• Excellent communication, collaboration, and diplomacy skills, particularly the ability to influence engineering practices and technical decisions without relying on formal authority.
• Comfortable working in a fully remote, async-first environment with colleagues and stakeholders distributed across multiple time zones.
• Experience working with external stakeholders, technology partners, vendors, or distributed engineering teams is a strong plus.
• Open-source experience, including contributing to, maintaining, or leading open-source projects, is highly valued.
• Previous experience in cybersecurity or Cyber Threat Intelligence (CTI) is not required but would be a significant advantage.

Benefits

• Competitive compensation combined with equity participation, allowing employees to share in the long-term success of the organization.
• Fully remote work from the United States East Coast, with a flexible and balanced approach designed to support different working styles and lifestyles.
• Freedom to choose the equipment and setup that best supports your productivity and working preferences.
• Twice-yearly regional and global gatherings, providing opportunities to meet colleagues in person, collaborate, and strengthen relationships beyond the remote environment.
• Opportunity to work on open-source cybersecurity technology with meaningful impact on organizations and security teams worldwide.
• Exposure to modern engineering practices and emerging technologies, including AI-assisted software development.
• A collaborative, globally distributed environment built around the values of cohesion, openness, responsibility, and equity.
• Significant technical ownership and influence across engineering practices, architecture, product development, and external technical collaboration.
