Senior UI Engineer

Do you want to help make the world safe from cyber attacks?

At Corelight, we believe that the best approach to cybersecurity risk starts with the network. Attackers can evade endpoint detection, firewalls and many other technologies - but they can’t avoid leaving digital footprints on the networks they traverse. Built on open-source innovations from Zeek, Suricata and YARA and refined through years of real-world use, Corelight transforms network footprints from physical, virtual and cloud networks into actionable insights. Our customers use these insights to accelerate incident response and proactively hunt for threats.

As a Senior UI Engineer for the Fleet Manager product, you will play a crucial role in leading the development and architecture of the frontend systems that enable clients to manage a fleet of sensors at scale and act on complex security data. This is a role for a high-agency engineer who doesn't just build components, but owns the user experience from end-to-end. You will bridge the gap between sophisticated data-heavy APIs and intuitive user interfaces, ensuring our customers can secure their enterprise with speed and precision.

Specific Responsibilities:

• Architect & Develop Modern UI: Design, develop, and maintain modern, scalable web applications using React + Typescript and related frontend technologies to drive the Investigator product forward.
• Contribute to the Frontend Lifecycle: Help with the implementation of complex user flows by translating wireframes and UX designs into high-quality, accessible, and performant UI components.
• Data-Intensive Integration: Work with the integration and consumption of GraphQL and REST APIs to power interactive, data-heavy visual interfaces capable of handling massive network datasets.
• Uphold Technical Excellence: Maintain and elevate code quality through rigorous testing, detailed documentation, and sophisticated code reviews.
• Autonomous Agile Delivery: Navigate agile development workflows—including sprint planning, retrospectives, and daily standups—with high independence and a focus on delivery.

Being successful on this team requires the ability to:

• Engineering Craft: Take pride in writing clear, well-structured, and maintainable code, and care deeply about long-term quality over short-term fixes.

• Systems Thinking: Think beyond individual components, understanding how state, data, and UI architecture work together across a large application.

• Product & User Empathy: Care about building interfaces that help users understand complex data quickly, and they make thoughtful tradeoffs in service of usability.

• Ownership & Accountability: Take responsibility for outcomes, follow work through from design to production, and continuously improve what they ship.

• Collaboration & Communication: Communicate clearly, welcome feedback, and work effectively across engineering, design, and product to solve hard problems together.

Qualifications/Requirements:

• Professional Experience: 3 to 7 years of professional software development experience, with a proven track record in Senior level roles.
• Frontend Mastery: Advanced in working with JavaScript/Typescript, Design LIbrary Components,  and React.
• Data & API Proficiency: Experience building and consuming GraphQL and REST APIs to support rich, data-heavy visual user interfaces.
• Architectural Knowledge: Solid understanding of Relational databases to better partner with backend teams.
• UX Partnership: Significant experience working directly with UX Design Teams to refine and implement complex user flows.
• Agile Fluency: Experience adopting and using Agile development methodologies within high-performing engineering teams.
• Communication: Excellent communication skills with the ability to collaborate across multiple teams and influence technical outcomes.
• Education: Bachelor's degree in Computer Science or related fields, or equivalent professional experience.
