Job ID: 1903
The Role:
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. 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.
Responsibilities:
- 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.
Requirements:
- 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.
- Demonstrated experience owning frontend architecture decisions and mentoring other engineers.
- Proficiency in modern JavaScript/TypeScript and a component-based framework (React preferred; Vue/Angular acceptable).
- Strong UX design skills — information architecture, interaction design, visual hierarchy — with a portfolio demonstrating design-to-code work.
- Experience designing interfaces for complex, data-heavy domains (dashboards, network/graph visualizations, security tools, DevOps tools, or similar).
- Proficiency with design tools such as Figma, Sketch, or Adobe XD.
- Familiarity with REST APIs and working closely with backend teams to shape data contracts for UI needs.
- 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.
Preferred Qualifications:
- 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).
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.

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.

What We Do
Quantum computers are a revolutionizing technology — they have the potential to transform business, society, and the planet for the better, and IonQ is at the forefront of this revolution. After over 25 years of academic research, IonQ was founded in 2015 by Chris Monroe and Jungsang Kim with $2 million in seed funding from New Enterprise Associates, a license to core technology from the University of Maryland and Duke University, and the goal of taking trapped ion quantum computing out of the lab and into the market. In the following three years, we raised an additional $20 million from GV, Amazon Web Services, and NEA, and built two of the world’s most accurate quantum computers. In 2019, we raised another $55 million in a round led by Samsung and Mubadala, and announced partnerships with Microsoft and Amazon Web Services to make our quantum computers available via the cloud. In 2020 and 2021, we built additional generations of high performance quantum hardware, added Google Cloud Marketplace to our cloud partner roster and announced a series of collaborations and business partnerships with leading academic and commercial institutions. On October 1st, 2021, IonQ began trading as IONQ on the New York Stock Exchange, making it the world's first public pure-play quantum computing company. We remain hard at work realizing the world-changing potential of quantum computing.
