Job Description
The Product Designer (UI/UX & Research) at LGC is responsible for leading user research and crafting flawless end-to-end experiences that optimize user-centered digital journeys. We are interested in someone who can focus on improving website performance and conversion through data-driven UX and CRO protocols.
We are looking for someone to ensure alignment with industry and digital guideline customer experience standards. By translating customer behavior into high-impact, intuitive design solutions, you will drive meaningful improvements in engagement across our digital ecosystem!
Key Responsibilities
- Lead comprehensive UX research efforts, including interviews, surveys, behavioral analysis, prototype testing, and usability studies, to identify user needs, confirm concepts, and produce actionable insights.
- Translate research insights, data, and business requirements into user journeys, wireframes, and prototypes, ensuring experiences are accessible, user-centered, and aligned with CX guidelines.
- Own the development and evolution of UI/UX deliverables, producing low and high-fidelity builds, interaction patterns, and design system components within Figma.
- Analyze website and product performance using GA, Hotjar, session recordings, VOC insights, and heatmaps to identify friction points and drive iterative optimization.
- Collaborate with web product management, developers, SMEs, and cross-functional teams to build scope, ensure technical feasibility, and deliver implementation-ready specifications.
- Facilitate workshops, compose reviews, and working sessions to build shared understanding, present design decisions clearly, and influence strategic, experience-led discussions.
- Champion user-first thinking, contribute to experimentation and optimization efforts, and support the development and management of the organization’s design system and new technologies. This helps to proactively find ways to improve and grow.
Skills You'll Use Every Day
- Proven expertise across UX research and UX building, including usability testing, behavioral analysis, CRO-aligned optimization, and the ability to translate insights into high-quality digital experiences.
- Strong analytical and problem-solving skills, adept at interpreting qualitative and quantitative data (e.g., Hotjar, GA, heatmaps) to guide iterative build improvements.
- Advanced proficiency with Figma, covering design systems, components, and variants, with a refined eye for UI craft, interaction development, and accessibility guidelines.
- Excellent communication, facilitation, and partner management skills, capable of influencing cross-functional teams and guiding collaborative decision-making.
- Ability to own end-to-end build delivery, from discovery research and journeys to high-fidelity prototypes and detailed specifications aligned with engineering partners.
- Familiarity with experimentation and analytics platforms (e.g., Optimizely, GA), with sufficient front-end awareness to collaborate effectively with developers and ensure composed intent is preserved through build.
- Highly organized and adaptable, able to balance critical thinking with hands-on delivery, while contributing to the evolution of the build system and broader design culture.
Qualifications
- Significant hands-on experience in UX/UI or Product Build, with end-to-end ownership of research, wireframing, prototyping, UI design, and delivery for complex digital products.
- Proven background in user research and usability testing – interviews, surveys, behavioral analysis, prototype testing – and synthesizing insights into clear development recommendations.
- Demonstrable ability to build intuitive, accessible, user-centered experiences supported by a strong portfolio showing UX flows, design systems, visual craft, and measurable product impact.
- Strong proficiency with Figma (components, variants, design systems) and experience with prototyping and collaboration tools.
- Experience working alongside web product management, engineers, and SMEs to guarantee feasibility, technical quality, and consistency throughout delivery phases.
- Solid grounding in user-centered build principles, accessibility standards, information architecture, and agile/iterative ways of working.
- Experience developing design systems and reusable components, with capability across multiple UX fields (research, IA, interaction, visual/UI) and supporting a wider design culture.
