[Hiring] Senior Frontend Developer @Exeon Analytics

Role Description

As a Senior Frontend Engineer at Exeon, you will be responsible for our UEBA (User and Entity Behaviour Analytics) product. You will work in a small cross-functional team of backend engineers, frontend engineers, and quality assurance engineers on a data-heavy single-page application that enterprise customers use to analyze network traffic and identify potential security risks. This data is rendered as tables, graphs, and dashboards. You will build out the frontend alongside our frontend engineers, while also helping to shape the overall UI and UX of the product and take its appearance and functionality to the next level.

• Develop and maintain front-end components for Exeon's UEBA product, an enterprise data analysis SPA built with React with emphasis on responsive design, performance optimization, and code quality (unit and integration tests).
• Translate complex user and entity behavior data and network security insights into intuitive visual representations (tables, graphs, dashboards), applying strong information architecture and UX principles.
• Handle large datasets and optimize frontend rendering to ensure responsive, performant user interfaces, even when working with complex data visualizations.
• Leverage AI-assisted development tools to improve engineering productivity while maintaining high standards of code quality, testing, security, and architectural consistency.
• Integrate with the UEBA backend APIs, ensuring efficient data fetching, transformation, and state management.
• Shape the UEBA product's UI/UX by contributing to design decisions and driving improvements in collaboration with engineers and other stakeholders, bringing independent thinking to the team.
• Drive technical excellence through code reviews and knowledge-sharing, and contribute to UEBA roadmap priorities from a frontend perspective.

Qualifications

• A frontend enthusiast who likes bringing the frontend to the next level, finding pragmatic solutions, working in a cross-functional team and staying up to date with frontend technologies.
• A professional who has at least 7 years of experience as a frontend engineer and at least a Bachelor's degree in Computer Science/Software Engineering (or similar).
• A frontend engineer who contributes to and improves the architecture and design of the product, ensuring a well-thought-through technical foundation.
• A technical expert who optimizes the code/application for the best performance and advocates for state of the art technologies and engineering practices.
• End to end ownership throughout the software lifecycle with a strong focus on solutions, code quality, and efficiency.
• Openness to AI-assisted development, with the ability to critically evaluate AI-generated solutions, challenge assumptions, and ensure code quality, maintainability, and security.
• Strong expertise in frontend development technologies (JavaScript, CSS3 and HTML5), React, and modern frontend build tooling (e.g., Webpack, Vite).
• Prior experience writing React functional components using React hooks, including lifecycle, state and side effects.
• Experience writing automated frontend tests, ideally using React Testing Library and Jest.
• A good understanding of Linux and Docker, with the ability to independently manage development environments and VMs.
• A good understanding of UI and UX principles such as clear information hierarchy (this isn't a designer role, but these skills will be useful).
