Solution Designer

About KB Tech

KB Tech Limited, part of the European Energy Exchange (EEX) Group, provides mission-critical trading infrastructure for energy commodities and financial markets globally. With over 20 years of experience and a lean, start-up mentality, we are a collaborative team of around 30 people looking for self-driven individuals to join our design and decision-making processes.

The role

We are seeking an experienced Solution Designer to own the translation of client requirements into clear, implementable solutions. You will take early-stage, often “rough” concepts and shape them into fully defined functional solutions — including user flows, high-fidelity UI designs and comprehensive requirements that development and testing teams can deliver against.

Key responsibilities

• Client engagement — gather and challenge requirements from clients and Product Management to ensure feasibility and alignment with platform capabilities.
• Solution design — translate business needs into end-to-end functional designs, defining system behaviour, edge cases and data interactions, using bespoke artefacts where needed.
• UX / UI design — create user flows and produce high-fidelity UI designs that align with existing patterns while ensuring usability in complex, data-driven interfaces.
• Delivery readiness — collaborate with developers and testers to refine requirements, support estimation and ensure features are “ready” for development.
• Requirement management — manage feedback cycles and incorporate technical feedback through to formal sign-off.

Skills & experience

• Strong experience in functional/business analysis or solution-design roles.
• Proven ability to turn ambiguous or incomplete ideas into actionable functional designs.
• Proficiency with Azure DevOps, Jira or similar delivery and backlog tools.
• Desirable: practical experience in UX/UI (high-fidelity mock-ups, design systems).
• Desirable: hands-on experience with energy or commodity trading platforms.
• A mindset that balances user experience, functional correctness and delivery practicality.
