Reporting line

Product / Innovation (working closely with Engineering, Research, and Commercial teams)

Role purpose

The UX/UI Designer is responsible for designing intuitive, efficient, and commercially valuable user experiences across TGS 4C digital products, with a strong emphasis on continuous user research throughout the full product lifecycle.

The role ensures that complex energy and infrastructure data is translated into clear workflows, interfaces, and interactions that are grounded in real customer needs, validated through research, and refined through ongoing feedback.

This role is high‑leverage: it reduces product risk, accelerates time‑to‑value, and increases customer confidence in the platform by embedding user insight into discovery, delivery, and iteration.

Key responsibilities

User research & discovery (core focus)

• Plan and conduct user research across all stages of the product lifecycle: discovery, concept validation, MVP, iteration, and optimisation
• Lead qualitative research activities including user interviews, workflow walkthroughs, usability testing, and feedback sessions with customers and prospects
• Partner closely with Research and Product teams to translate market and customer insight into clear user needs, hypotheses, and design opportunities
• Synthesize research findings into actionable insights, clearly articulating user problems, behavioural patterns, and unmet needs
• Ensure design decisions are evidence‑led and traceable back to user insight

User experience & workflow design

• Map core customer workflows (e.g. developer, investor, EPC, supplier personas) into clear end‑to‑end product
• Translate user research, interviews, and usability feedback into practical UX improvements
• Design information architecture and navigation that supports discovery, comparison, and decision‑making
• Continuously validate workflows with users as products evolve

UI design & prototyping

• Design key screens and interactions including filters, saved searches, maps, project detail pages, document viewers, timelines, and alert controls
• Produce clickable prototypes (e.g. Figma) to test concepts early and de‑risk engineering effort
• Define and maintain a consistent UI component library to improve design quality and development speed

Usability testing & iteration

• Plan and run lightweight usability testing with internal stakeholders, design partners, and end users
• Evaluate usability, clarity, and perceived value of new and existing features

• Synthesise findings into clear recommendations and prioritised design iterations
• Iterate designs rapidly based on feedback, constraints, and product learning

Cross‑functional collaboration

• Work closely with Product, Engineering, Research, and Commercial teams to align UX and research insight with product strategy and customer value
• Support product discovery, roadmap prioritisation, and MVP definition through user insight

• Support product packaging, positioning, and perceived value through clear UI structure and value framing
• Act as the UX and user‑research advocate in delivery discussions, balancing user needs with technical and commercial realities
  
  

Key deliverables

• User research plans, interview guides, and usability testing frameworks
• Synthesised research outputs (insight summaries, key findings, opportunity statements)
• Clickable UX/UI prototypes for MVPs and new feature workflows
• Documented user flows, journeys, and information architecture

• Usability testing insights and iteration plans
• Reusable UI component patterns (filters, maps, timelines, alerts, document views)
  
  

Skills & experience

Essential

• Proven experience as a UX Designer, UI Designer, or Product Designer with significant responsibility for user research
• Strong portfolio demonstrating user‑centred problem discovery, workflow design, interaction design, and iteration
• Hands‑on experience planning and conducting user research (interviews, usability testing, workflow analysis)
• Experience designing complex, data‑driven interfaces with large datasets, filters, maps, or dashboards

• Proficiency with design and prototyping tools (e.g. Figma)
• Strong communication skills and ability to clearly articulate research insights and design rationale

Desirable

• Experience working with geospatial, energy, infrastructure, or industrial data products
• Familiarity with agile and discovery‑led product development environments
• Experience contributing to or maintaining design systems
• Experience working closely with market research, product analytics, or commercial teams
  
  

Impact of the role

This role directly reduces key product risks by embedding user research throughout delivery, including:

• Poor problem–solution fit through early and continuous validation with users
• Misalignment between buyer expectations and product value
• UI complexity that increases cognitive load or reduces trust
• Building features based on assumptions rather than evidence
• Alert fatigue and noise through better understanding of user behaviour
  
  

Values & ways of working

• Deeply user‑centred and evidence‑led
• Commercially aware and outcome‑focused
• Pragmatic, iterative, and comfortable with ambiguity
• Collaborative, open to feedback, and confident challenging assumptions
  
  

What success looks like

• User research is embedded as a standard part of product discovery and delivery
• Design decisions are clearly informed by user insight at every stage
• Users can complete core tasks faster and with greater confidence
• Engineering teams build the right things faster with fewer UX‑driven reworks
• Product feels intuitive, credible, and clearly aligned to real customer needs
• UX and user research are recognised as core capabilities within product development
