About The Position

At Prophet Security, we're not just building a platform that automates complex security tasks – we're building a company where every team member has a direct impact on customer success. As a member of our team, you'll have the unique opportunity to work closely with our customers, understand their needs, and see firsthand how your work is making a difference. If you're passionate about building impactful products, working in a collaborative environment, and gaining valuable experience in a fast-growing startup, we encourage you to apply. Prophet Security’s founding team brings over 30 years of cybersecurity experience from leading companies including Abnormal Security, Expel, Mandiant, McAfee, Oracle, Red Canary, Red Hat, Riverbed, and Symantec. We are now focused on disrupting the $400B security labor market by building the future of automated security operations. Prophet Security is a force multiplier for security teams. Our platform analyzes alerts, develops and executes investigation plans, and provides detailed findings and actionable recommendations. Analysts review these investigations, adding context and feedback that are continuously incorporated into future automation. Our mission is to fundamentally shift cybersecurity power dynamics to favor defenders — making security teams more effective, efficient, and scalable. We're looking for a Senior Full Stack Engineer to join our Engineering team to build the user-facing surface of our AI SOC platform. As an early engineer, your contributions will directly shape our product, architecture, and engineering culture. In your first 6 months, the bulk of your work will be on the Frontend: building the interfaces that security analysts rely on every day to investigate alerts, review AI-generated findings, and respond to threats. As the product and team grow, you'll have the opportunity to broaden into backend systems: APIs, data pipelines, integrations, and the services that power the experience you build. We're looking for someone who is excited about both ends of the stack, with depth and recent hands-on experience in modern frontend development. You'll work closely with design, product, backend engineers, and our security operations team — and directly with customers — to ship features that meaningfully change how security teams work.

Requirements

5+ years of professional software engineering experience, with significant recent experience building production frontend applications.
Strong proficiency with React and TypeScript, and a deep understanding of modern frontend fundamentals — component design, state management, performance, accessibility, and testing.
Experience working across the stack — comfortable building and consuming APIs, reasoning about data models, and contributing to backend services.
A strong product sensibility: you care about how things look, feel, and work for the people using them, and you collaborate naturally with designers and PMs.
Track record of shipping high-quality work independently in ambiguous, fast-moving environments.
Excellent communication skills and a collaborative, low-ego approach to building software with others.
Excited about working closely with customers and turning their feedback into product improvements.

Nice To Haves

Familiarity with Python or Go is a plus.

Responsibilities

Design and build the user-facing experiences of our AI SOC platform — from analyst workflows for alert triage and investigation, to dashboards, configuration interfaces, and admin tooling.
Partner with design and product to translate complex security workflows into clear, performant, and accessible interfaces.
Own features end-to-end: shape requirements, build the UI, wire up the APIs, and ship to customers.
Contribute to architectural decisions for our frontend codebase — component patterns, state management, testing strategy, and performance.
Extend into backend work as the product evolves: building and refining APIs, data models, and services that power the user experience.
Collaborate directly with customers and our security operations team to understand real-world needs and incorporate feedback quickly.
Help raise the bar for engineering quality through thoughtful code review, documentation, and mentorship.
