Description

Terra Security provides agentic AI-powered continuous penetration testing aligned to code changes and evolving attack surfaces, combining a swarm of trained AI agents with human supervision for safety and control. Fortune 500 organizations trust Terra to ensure every attack surface is covered across the web, AI, internal apps, APIs, mobile, networks, and the cloud. Terra is on track to become the next breakout cybersecurity company with $38 million raised to date, including a $30 million Series A led by Felicis Ventures with participation from Dell Technologies Capital, Silicon Valley CISO Investments (SVCI), SYN Ventures, LAMA Partners, Underscore VC, and Capital One Ventures. Summary As a Senior Fullstack Engineer, you will help build Terra’s customer-facing platform - from the web and user experience to the APIs that power them. You will work across the stack, turning product goals into reliable, scalable software that security teams depend on every day. We are looking for a senior engineer who owns meaningful work end-to-end, raises the bar on code quality, and collaborates well in a fast-moving environment. You will partner with product, design, and security experts to ship features that are clear, dependable, and built to last. What You’ll Do Design and build scalable, production-grade customer-facing frontend and backend systems - where quality, reliability and attention to detail matter. Work closely with UX designers, product, and design leadership to deliver features end to end. Own entire features and complex projects from technical design through implementation, testing, deployment, and monitoring. Extend and maintain our design system and shared web UI patterns so new work stays consistent, accessible, and maintainable as the product evolves. Help shape long-term architecture and engineering practices, keeping a high bar for code quality, collaboration, and culture in a fast-paced environment. Take on zero-to-one challenges as we grow the platform for larger, more complex enterprise customers. Requirements 6+ years of professional experience in fullstack software development with UI orientation, ideally in high-growth or product-led environments. Deep hands-on expertise with TypeScript, Node.js, and React. You are a self-starter and creative problem solver who thrives under ambiguity and delivers high-quality results quickly. Strong teamwork and communication skills, with the ability to explain complex technical trade-offs to both technical and non-technical stakeholders. A strong commitment to quality first, with rigorous self-driven QA to ensure high standards in both code and final outputs.

Responsibilities

Design and build scalable, production-grade customer-facing frontend and backend systems for an AI-powered penetration testing platform. Own features end-to-end from technical design through implementation, deployment, and monitoring while maintaining the design system.
