About the Role
We are looking for a UX/UI designer to join our growing engineering team in central London. In this role, you will hold a senior position and be a driving force with leadership for UX/UI design within our design and usability function.
Key Responsibilities
- Responsibility for UX/UI Design of our robotic platform, inc. supporting the definition of processes and ways of working, strategy, and planning.
- Championing a user centered-design process in a multidisciplinary R&D team, using an understanding of our end-users and user needs to ensure we design the right product.
- Actively supporting and steering user research activities / usability evaluations to inform the design of our products, including identifying research needs and questions, and supporting the delivery of research in terms of study plans, moderation, and reporting.
- Confidently communicating best practice, design concepts, and design rationale to the R&D team and wider business stakeholders for alignment on short and longer-term design.
- Curating and managing product design systems, aligned with relevant design guidance and usability considerations, and backed by strong design rationale.
- Distilling complex user interactions to deliver high-fidelity wireframes, visual designs, workflows and detailed written specifications to developers as part of an agile process.
- Proactively estimating design task effort then owning design efforts from ‘concept’ to ‘ready for development’, ensuring delivery in a timely manner accounting for potential roadblocks.
Who We’re Looking For
- At least 7+ years’ experience working as a software designer in previous roles, with strong, demonstrable experience in both user experience and visual design for complex systems.
- A degree in Graphic Design, Interaction Design, Human-Computer Interaction Design, Industrial Design, Human Factors or a related discipline.
- A self-starting attitude, and proven ability to take ownership of designs and seek inputs from different teams to deliver to project / product milestones. Ability to drive design, productivity, change, and outcomes with little supervision and effective collaboration.
- A comprehensive portfolio showing experience of leading the design of complex digital products, across the product lifecycle, and ability to effectively communicate the value of the UX/UI work.
- Highly proficient using Figma, and Adobe Creative suite (preferred).
- Eligibility to work on-site at our central London office.
Proven track record for ownership, leadership, and effective execution of:
- UX/UI design and strategy for complex systems.
- In-depth understanding of User-Centred Design principles and techniques, and practical experience of applying these to benefit design, usability, and broader business needs.
- Developing and maintaining a design system based on sound design rationale, implementing design change efficiently across the platform, and tracking design change control.
- Systems-thinking, visualising design (short and longer-term) across the platform as well as for each sub-system, with critical thinking around how design can elicit correct and incorrect use across hardware and software user interactions.
- Collaboration with a user research / usability team, including planning and contributing to research, and analysing and owning insights for design decisions.
- Design reviews / workshops with multi-disciplinary teams with actionable outputs and agreed direction for product design and wider strategic efforts/road mapping.
- Handover of designs to software developers, inc. design reviews, detailing design specifications, reviewing implementation, and testing.
- Process definition and improvement, inc. agile methodologies. Experience We Value
- Experience developing user interfaces for medical robotics or regulated medical devices.
- Experience working with design controls, risk management, human factors, and verification and validation activities for medical device development.
- Experience in the graphic design, to support the design of accompanying documentation such as instructions for use, marketing materials, and labelling.
- Comfort operating in a fast-paced startup environment where priorities evolve, and ownership is broad.
Why Join Us?
