Principal Product Designer

About the role

This role defines design for critical operations within field service, asset management, manufacturing, and supply chain environments. You will own end-to-end problem framing and delivery in cross-functional squads, directly influencing safety, efficiency, and critical decisions for maintenance engineers and operations planners. The work encompasses the full journey from initial discovery through implementation and the measurement of shipped outcomes. Designers shape not only how products look and feel but also how they function in high-stakes operational contexts. You will create user flows, wireframes, prototypes, and polished visuals that balance complex business needs with user realities. Collaboration with product and engineering partners happens daily, requiring a proactive stance rather than a passive waiting for instructions. Design decisions are ultimately judged by tangible outcomes such as usability, conversion, and customer satisfaction in demanding industrial settings. Most design teams within this context maintain a living design system to ensure consistency and efficiency across enterprise products.

Key facts

What you'll do

Problem framing for defined feature areas evolves into production-ready Figma files, supported by clear rationale developed within cross-functional squads alongside engineers and product managers.

You will design AI-driven features with a critical awareness of where artificial intelligence genuinely supports operations and where it introduces significant risk, including crafting prompts, defining fallbacks, and orchestrating human-in-the-loop scenarios.

You will evaluate how interface paradigms might become obsolete and determine what emerging interaction models should replace them to maintain future usability.

You will conduct discovery work that transforms ambiguous operational challenges into clear design opportunities, utilizing research methods to validate assumptions before major investment.

You will run independent research, plan studies, conduct interviews with engineers and planners, and translate findings into concrete product direction and design strategies.

You will work effectively within cross-functional squads, making real-time decisions with engineers and product managers rather than waiting for detailed briefs to be handed down.

You will use Figma proficiently, applying strong visual craft to support your thinking and ensuring that designs are both coherent and production feasible.

You will treat accessibility as a core design constraint from the very first concept, ensuring that critical operations interfaces remain usable for all intended users.

You will measure outcomes such as task success rates and support ticket volume to drive the next iteration and prove the impact of your design work.

Requirements

The posting states a bachelor's degree requirement; you must bring this credential to be considered for the role.

You must possess eight or more years of end-to-end product design experience, demonstrating a deep track record of owning projects from discovery through shipped outcomes.

You must provide evidence of comfort running independent research, planning studies, conducting interviews, and turning qualitative findings into strategic direction.

You must work effectively in cross-functional squads, making real decisions with engineers and product managers rather than waiting for external briefs.

You must use Figma proficiently, with strong visual craft that supports your thinking and communicates design intent clearly to stakeholders.

You must treat accessibility as a core design constraint from the start, integrating it into your process without treating it as an afterthought.

You must consider how AI reshapes the design problem beyond merely adding features, addressing implications for interaction models and user trust.

You must measure outcomes such as task success and support ticket volume to validate design impact and guide future iterations.

Nice to have

An interest in emerging technologies such as AI, voice, and ambient computing, and understanding how they apply to industrial environments.

Familiarity with enterprise design systems and a demonstrated commitment to accessibility best practices.

Experience working in agile squads with decision-making authority and a data-informed approach to product development.

Practical notes

This role is based in Staines-upon-Thames, gb, and requires a degree; the position is full-time and permanent.

You will work in a hybrid environment with scheduled onsite collaboration.

Typical interview steps

Design interviews usually include a portfolio review, a design exercise, and a team conversation. Candidates present past work and explain their process and decisions. Some loops include a live design challenge. Communication matters as much as the visual output. Portfolios are strongest when they show the problem, the constraints, and the iteration, not just the final screens. Interviewers also watch how you take feedback.

Good to know

The role focuses on complex operations interfaces where software directly affects mission success.

Designers work with emerging technologies such as AI, voice, and ambient computing.

The company maintains an enterprise design system and emphasizes accessibility.

The team operates in agile squads with decision-making authority.

This role involves measuring impact through quantitative and qualitative data.

Questions to ask

Worth asking in any interview: how the team measures success, who the role works with daily, what the onboarding looks like, and what the company is trying to achieve this year. Asking what past hires did well is a strong final question. Keep the list short and pick the questions that matter most to you.

Career growth

Design careers grow from junior to senior, staff, and principal levels. Some designers move into design management or design operations. Specializations include UX research, interaction design, and brand design. Cross-functional influence grows with seniority. Senior designers are expected to influence product strategy, not just execute visuals. Building a habit of user research strengthens any design career.
