Product Designer (UX / UI)

Role Purpose

The Product Designer ensures Rimthan’s ventures move from idea to testable product experiences at speed. With expertise in UX, rapid wireframing, and workshop leadership, they are highly efficient in transforming limited evidence and incomplete inputs into actionable designs that can be validated quickly.

This role is about delivery at pace. The designer thrives in ambiguity, reducing complexity into clear user flows and prototypes that keep projects moving. They balance user-centric thinking with practical constraints, ensuring solutions are both intuitive and feasible.

Core Responsibilities

Fast UX Execution

• Translate assumptions and incomplete requirements into clear, testable wireframes and prototypes

• Create user flows and designs quickly, optimizing for speed while keeping usability in focus

• Adapt and iterate rapidly with minimal research inputs

Workshop Facilitation

• Lead design workshops with clients and internal teams to align direction quickly

• Use collaborative sessions to clarify needs, frame problems, and accelerate decision-making

• Extract insights from limited evidence and turn them into actionable design directions

Design Delivery

• Build intuitive, human-centered product experiences under tight timelines

• Provide designs that are technically feasible and easy for engineers to implement

• Maintain and reuse design systems and UI patterns to accelerate delivery

AI-Accelerated Workflows

• Leverage AI to speed up research synthesis, wireframing, and prototyping

• Use AI tools to expand ideation and reduce time spent on repetitive design tasks

Cross-Functional Collaboration

• Partner with Venture building, PMs and engineers to ensure alignment and speed of execution

• Communicate design intent with clarity, avoiding over-research or analysis paralysis

• Act as the design voice in fast-moving, client-facing contexts

Success Metrics

• Speed of delivery: ability to produce usable wireframes, flows, and prototypes in days, not weeks

• Pragmatism under constraints: delivering clear, testable designs with limited evidence or research

• Adoption and client alignment: designs that are understandable, actionable, and aligned with venture goals

• Delivery engine impact: reuse of design systems and patterns that reduce future turnaround times

Expectations

• Operates independently in ambiguous contexts with incomplete inputs

• Prioritizes delivery and pragmatism over perfection

• Anticipates design risks and addresses them quickly with lightweight testing or stakeholder alignment

• Communicates clearly to move teams forward fast, even when evidence is limited

• Balances speed with enough quality to maintain credibility and user trust

Cultural Alignment

• Bias for action: prefers shipping testable designs over waiting for perfect research

• Customer-focused pragmatism: keeps users in mind while adapting to limited evidence

• Collaborative and efficient: works as an equal partner with PMs, engineers, and venture teams

• Ownership and accountability: takes responsibility for results, even under pressure

• Moves fast with discipline: speed without losing clarity, integrity, or cohesion
