About the role

As a Senior Product Designer on the Case Management team, you will own and shape the experience of one of ENSEK's most strategically important products. Flow is our case management and AI-assisted workflow platform, and while an MVP already exists, the product is still early in its journey. This is an opportunity to define what the experience becomes as it scales, making key decisions about what to evolve, what to redesign and where to invest next.

Working closely with Product and Engineering, you'll operate in a highly collaborative and fast-moving environment, combining strategic thinking with hands-on design delivery. You'll play a key role in designing trustworthy AI-assisted experiences, helping users navigate complex workflows through thoughtful automation, clear feedback mechanisms and human-centred decision-making. You'll also use AI tools throughout your own design process to accelerate discovery, synthesis, ideation and iteration.

Key responsibilities

• Own and evolve the end-to-end case management experience, building on the existing MVP and helping define the future direction of the product.

• Design AI-assisted and human-in-the-loop workflows that balance automation with transparency, trust and user control.

• Map and optimise user journeys across complex operational workflows, considering both business and technical requirements.

• Partner closely with Product Managers and Engineers from early discovery through to delivery and iteration.

• Lead design exploration in ambiguous problem spaces, turning emerging opportunities into intuitive product experiences.

• Champion best practices for designing AI-assisted experiences, including confidence indicators, explainability patterns and error handling.

• Contribute to design systems thinking, particularly as it relates to AI interaction patterns and workflow-based experiences.

• Use AI tools to support research synthesis, scenario modelling, prototyping and rapid iteration.

Key outcomes

• A scalable and intuitive case management experience that supports business-critical workflows.

• AI-assisted experiences that improve productivity while maintaining user trust, transparency and control.

• Simplified and efficient user journeys across complex operational processes.

• Clear alignment between product goals, customer needs and design decisions.

• Strong collaboration across Product, Design and Engineering, enabling high-quality delivery.

• Continued evolution of the product from MVP to a mature product with measurable customer impact.

• Design solutions that establish best practices for AI-assisted workflows across the wider platform.

Experience required

• Proven experience owning end-to-end UX design across a product area, from discovery through delivery.

• Hands-on experience designing AI-assisted or agentic workflows, including human-in-the-loop experiences, feedback loops, confidence states, explainability and error handling.

• Comfortable working in greenfield or early-stage product environments where requirements and opportunities are still emerging.

• Strong strategic thinking, with the ability to connect design decisions to product goals and business outcomes.

• Excellent collaboration and communication skills, with a track record of working closely with Product and Engineering teams.

• Experience using AI tools throughout the design process to accelerate insight generation, exploration and iteration.

• Strong UX foundations combined with the ability to navigate ambiguity and make progress in evolving environments.

• Experience working on B2B, operational or workflow-heavy products preferred.

• Experience with case management systems, workflow platforms or AI-powered tooling would be highly advantageous.
