Senior Frontend Engineer

At Mesh Security, we’re on a mission to revolutionize enterprise security. Our platform gives modern security teams full context, visibility, and control across fragmented cloud environments—so they can prevent, detect, and respond to threats in real time.

We're looking for a Senior Frontend Engineer to own and drive the web experience of our core platform. This is a high-impact role at the intersection of user experience and cybersecurity—where you’ll craft intuitive interfaces that help security teams manage cloud policies, investigate vulnerabilities, and respond to threats at scale.

You’ll join a top-tier R&D team, working closely with backend and product leads to shape both the UX and the technical architecture of our platform. If you're passionate about building elegant, high-performance web apps in a fast-paced startup environment—this role is for you.

💡 What you’ll do

• Own the end-to-end development of key frontend features—from design and architecture to implementation and testing
• Lead UI development using React, TypeScript, GraphQL, Apollo, and MUI
• Define API contracts (GraphQL schemas) and collaborate with backend engineers on implementation
• Drive technical and architectural decisions to ensure performance, scalability, and maintainability
• Contribute to design reviews, code reviews, and overall team best practices
• Deliver elegant UX without compromising on code quality or performance

🧠 What we’re looking for

• 6+ years of experience building modern web applications using React and TypeScript
• Deep expertise in React architecture, patterns, and best practices (e.g., hooks, state management, component composition, performance optimization)
• Proven ownership of full lifecycle frontend projects (from design to deployment)
• Experience designing and consuming APIs (ideally GraphQL)
• Strong grasp of performance, maintainability, and testing best practices
• Ability to think holistically about product UX, system architecture, and scalability
• Excellent communication skills and a collaborative mindset

Bonus Points

• Hands-on experience in cybersecurity or cloud security domains
• Experience with enterprise SaaS platforms

• Work with world-class engineers in a fast-moving team
• Shape the frontend architecture and user experience of our core product
• Build tools that help security teams stay ahead of complex threats
