Senior Product Designer (Client-Facing)

PhysicsX is a deep-tech company of scientists and engineers, developing machine learning applications to massively accelerate physics simulations and enable a new frontier of optimisation opportunities in design, engineering, and systems control.

We help our customers fundamentally improve their concepts and designs, transform their engineering processes and drive operational product performance. We do this in some of the most advanced and important industries of our time – including Renewables & Sustainability, Space, Aerospace, Medical Devices, Additive Manufacturing and Energy. Our work creates positive impact for society, be it by improving the design of artificial hearts, reducing CO2 emissions from aircraft and road vehicles, or increasing the performance of wind turbines. 

We are a rapidly growing company but prefer to fly under the radar to protect our customers’ confidentiality. We are about to take the next leap in building out our technology platform and product offering. In this context, we are looking for capable and enthusiastic Product Designers to join our team. If all of this sounds exciting to you, we would love to talk (even if you don't tick all the boxes).

Position Overview:

We’re seeking an exceptional Senior Product Designer to join our team, with the unique opportunity to work on cutting-edge AI and engineering-based solutions for enterprise clients. As a Senior Product Designer, you’ll be instrumental in creating user-centred design solutions that simplify complex systems, collaborating closely with Delivery Leads, technical teams, and clients. This is a UK based (London) role, where the role requires occasional travel to the United States. As such, candidates with the ability to travel to and work in the United States without visa sponsorship are preferred. This is an exciting opportunity to work at the intersection of AI, design, and enterprise-scale challenges, all while shaping products that push boundaries.

What you will do

• Lead discovery and research efforts: Conduct strategic user research to uncover insights, translating complex client requirements into intuitive, user-centred solutions.
• Design for enterprise innovation: Develop wireframes, prototypes, and high-fidelity designs that simplify workflows for technical users while addressing enterprise-scale challenges.
• Collaborate cross-functionally: Partner with Delivery Leads, Data Scientists, and Simulation Engineers to deliver designs that are both innovative and technically feasible.
• Facilitate workshops and alignment sessions: Engage stakeholders through workshops and presentations to align on vision and ensure decision-making throughout the design process.
• Iterate for impact: Use user testing, analytics, and feedback to refine and optimise designs for maximum usability and impact.
• Champion user-centred practices: Advocate for best practices across teams while balancing commercial objectives and client needs.
• Mentor and elevate: Guide junior designers, fostering a culture of excellence in design across the organisation.
• Occasional travel to the US for client meetings and project work

What you will bring

• Experience: 5+ years of experience delivering end-to-end design projects, ideally within an agency, consultancy, or enterprise context.
• Education: Bachelor’s degree in Design, HCI, Computer Science, or equivalent practical experience.
• Technical expertise: A deep portfolio showcasing experience in enterprise UX/UI design, with a focus on solving complex problems and delivering scalable solutions.
• Tools: Proficiency in design tools like Figma, Adobe Creative Suite, and research platforms such as Dovetail.
• Communication skills: Strong presentation and communication skills, with the ability to clearly articulate design decisions to diverse stakeholders.
• Bonus points: Experience working with AI/ML interfaces, designing for data-heavy applications, working in an Engineering environment or familiarity with 3D tools (e.g., Blender, Houdini, Unity3D).
• Additionally, eligibility to work in the US is highly desirable

What we offer

• Be part of something larger: Make an impact and meaningfully shape an early-stage company. Work on some of the most exciting and important topics there are. Do something you can be proud of 
• Work with a fun group of colleagues that support you, challenge you and help you grow. We come from many different backgrounds, but what we have in common is the desire to operate at the very top of our fields and solve truly challenging problems in science and engineering. If you are similarly capable, caring and driven, you'll find yourself at home here 
• Experience a truly flat hierarchy. Voicing your ideas is not only welcome but encouraged, especially when they challenge the status quo 
• Work sustainably, striking the right balance between work and personal life.
• Receive a competitive compensation and equity package, in addition to plenty of perks such as generous vacation and parental leave, complimentary office food, as well as fun outings and events
• Work in a flexible setting, with the opportunity to collaborate in our lovely Shoreditch office and enjoy a good proportion of time working from home, if desired. Get the opportunity to occasionally visit our customers' engineering sites and experience first-hand how our work is transforming their ways of working
• Use first-class equipment for working in-office or remotely, including HPC 




We welcome applications from all qualified individuals. If you believe you are the right fit for this role but have concerns about travel or work authorisation, we encourage you to apply so we can discuss your unique situation.
