Senior Front End Engineer
Posted Updated
- This role blends product design thinking with hands-on frontend engineering — you’ll turn complex network and security data into interfaces that are intuitive, fast, and trustworthy for security and network teams
- As a senior member of the team, you’ll also help shape frontend architecture, mentor junior engineers, and drive design/engineering best practices. You’ll work closely with product managers, backend engineers, and QA/solutions teams to ship features that make sense to real users under real operational pressure
- Design and implement responsive, accessible UI components for the platform using modern frontend frameworks (React, Vue, or similar)
- Translate complex network security concepts — topology maps, risk/posture scores, policy rules, alerts, remediation steps — into clear, usable visual interfaces
- Own end-to-end UX for key workflows: onboarding, network/device discovery, dashboards, drill-down investigations, and reporting
- Create wireframes, prototypes, and high-fidelity mockups (Figma or similar) and iterate based on user feedback and usability testing
- Collaborate with backend engineers to define and consume APIs, ensuring data-heavy views (topology graphs, tables, charts) remain performant at scale
- Partner with QA and Solutions Testing teams to validate that workflows behave correctly and intuitively across real customer network scenarios
- Conduct or support usability testing and gather feedback from customers, sales engineers, and support teams to continuously refine the UX
- Maintain and evolve a component/design system for consistency across the platform
- Ensure UI meets accessibility (WCAG) and cross-browser compatibility standards
- Monitor frontend performance (load times, rendering of large topology/data sets) and optimize as needed
- Help define and evolve frontend architecture, tooling, and coding standards across the team
- Mentor mid-level and junior frontend/UI engineers through code reviews, pairing, and design critiques
- Drive technical decisions on state management, component architecture, and performance for a growing, data-intensive platform
- What Success Looks Like:
- Complex network and security data is presented in ways that are immediately understandable to security/network admins
- Key workflows (discovery, posture review, remediation) feel fast, guided, and low-friction even for less technical users
- Design and engineering teams ship UI changes with confidence, backed by usability validation and a consistent design system
- Frontend architecture scales cleanly as the platform and team grow, with junior engineers leveling up under your guidance
- We’re looking for a Senior Frontend Engineer with 5+/8+ years of experience to design and build the interface for our Quantum Security platform
- Familiarity with REST APIs and working closely with backend teams to shape data contracts for UI needs
- Demonstrated experience owning frontend architecture decisions and mentoring other engineers
- 5+/8+ years of experience as a frontend engineer, UI/UX engineer, or product designer with strong coding ability, ideally on data-dense or technical SaaS products
- Proficiency in modern JavaScript/TypeScript and a component-based framework (React preferred; Vue/Angular acceptable)
- Proficiency with design tools such as Figma, Sketch, or Adobe XD
- Understanding of responsive design, accessibility standards (WCAG), and cross-browser/device compatibility
- Ability to conduct or contribute to usability testing and translate findings into design/engineering improvements
- Experience designing interfaces for complex, data-heavy domains (dashboards, network/graph visualizations, security tools, DevOps tools, or similar)
- Strong UX design skills — information architecture, interaction design, visual hierarchy — with a portfolio demonstrating design-to-code work
- Prior experience in network security, cybersecurity, or IT infrastructure SaaS products
- Familiarity with data visualization libraries (D3.js, Recharts, Cytoscape.js, or similar) for rendering network topology and graph-based data
- Basic understanding of Layer 2/Layer 3 networking concepts (VLANs, routing, ACLs) to better design for technical users
- Experience with design systems and component libraries at scale
- Exposure to CI/CD pipelines and frontend testing frameworks (Jest, Playwright, Cypress)
