Job summary

cside is seeking a senior full-stack developer to ship the product surface of the platform — dashboards, APIs, and customer tooling that convert billions of signals into actionable security insights.

You'll work near data and customers, building features end to end with TypeScript on React and Node, focusing on high-volume, low-latency systems and a culture of quality. This fully remote role requires US-based candidates ready to travel for offsites.

Qualifications

• 5+ years building production web applications.
• Strong TypeScript; front-end React, back-end Node or similar.
• Experience with real-time or high-volume data systems.
• Care about performance and can explain slowdowns.
• Comfortable with ambiguity; you scope your own work and ship without waiting to be told.
• Writes clearly — code, review comments, and design docs alike.
• Genuine interest in web security; eager to become proficient.
• Based in the United States and authorized to work here, with 4+ hours of daily overlap with US Pacific hours.
• Willing to travel for 2-3 company offsites per year.

Responsibilities

• Build and ship features across the stack, from API endpoints to the dashboard our customers live in every day
• Design and implement APIs that serve high-volume, low-latency security telemetry
• Work with our real-time data pipeline to surface detections clearly, without drowning users in noise
• Turn complex security signals into interfaces that make the right action obvious
• Own features end to end: design, implement, test, ship, measure, iterate
• Improve performance and reliability of systems processing signals at scale
• Contribute to code review, technical design, and the engineering standards we hold each other to
• Partner with product and security research to take detections from prototype to production
