Description du poste

Be part of a team of engineers helping organizations fight fraud and abuse. We help organizations move beyond alerts, dashboards, and static reports by turning threat intelligence into automated monitoring, investigations, due diligence, and decision-ready risk workflows. Our platform continuously monitors global signals, from news, social media, domains, and open web sources to alternative forums, criminal marketplaces, and the dark web, using AI agents, machine learning, and human analyst expertise to filter noise, connect context, and surface what matters.

The Role

As a Sr. Frontend Software Engineer, you are a solid, self sufficient contributor who focuses heavily on creating intuitive, streamlined user interfaces that maximize user efficiency and eliminate workflow friction. You don't just write code; you design and build complete frontend systems, reduce architectural complexity, and act as a domain expert in crafting seamless user experiences. You’ve taken in-use systems and rebuilt them while they are serving customers. You will be laying the groundwork for the future of threat intelligence while shipping high-impact work today.

What You’ll Do

• Design and build complex frontend systems end to end, from stakeholder requirements through to production
• Build investigation and monitoring workflows: dense data tables, entity/relationship views, real-time alerting, and agentic/AI-assisted UX
• Drive UX in partnership with Product, design, and backend engineers, using usage metrics and customer feedback
• Prototype quickly, then refine to production quality
• Build and maintain a component library and design system others can extend
• Improve the codebase as you go: test coverage, performance, simplicity

What You’ll Bring

• 5+ years building production web applications, including senior or lead ownership of frontend architecture
• Deep expertise in React and TypeScript
• Experience building design systems and component libraries
• Experience with data-heavy UIs: organization, performance, visualization
• Strong product and UX instincts, from typography to deployment pipelines

Nice to Have

• Python API experience (FastAPI / Django)
• Background in security, threat intel, fraud, or trust & safety
