Product designer

What does a product designer do?

A product designer shapes how a digital product looks, feels and works for the people who use it.

You take a problem from early research through wireframes and prototypes to the final screens that engineers build. The work covers apps, websites and internal tools.

In a Singapore organisation, product designers usually sit in a product or design team at a bank, government agency, tech company, start-up or agency. Some report to a head of design. Others report to a product or engineering lead.

You work daily with product managers, engineers and researchers. You also meet business owners, marketers and customer service teams who need to understand and back your design decisions.

What the work involves

• Run or join design sprints with product managers, engineers and researchers to agree what to build next.
• Sketch flows and build wireframes and clickable prototypes in tools such as Figma.
• Plan and run usability tests, then turn what you see into design changes.
• Check user behaviour data and customer complaints to find where people get stuck.
• Present designs to stakeholders and explain what the design improves for users and the business.
• Hand over final designs and reusable components to engineers, then review what ships.

Product designer job description

We are hiring a product designer to design web and mobile features from concept to launch.

You will work in a cross-functional squad with product managers, engineers and researchers. You will run research, build prototypes, test them with users and refine them. You will also improve products that are already live, using user feedback and usage data.

Responsibilities

• Plan design work with product managers, engineers and front-end developers for each sprint.
• Run workshops and meetings to gain support from stakeholders inside and outside the team.
• Define the user problem and the scope of the design process before starting.
• Work with researchers to learn about customers and bring findings into design decisions.
• Create user flows, journey maps, wireframes and prototypes.
• Run usability tests and report what you find with clear recommendations.
• Produce polished, production-ready screens and maintain components in the design system.
• Review user behaviour data and competitor products to guide design choices.
• Propose improvements for products that are already launched.
• Explain the value of design to colleagues in other functions.

Requirements

• Diploma or degree in design, interactive media, human-computer interaction, psychology or a related field. A strong portfolio can count for as much.
• Typically 2 to 5 years of product or UX design experience for a mid-level role. Entry roles may accept 0 to 2 years.
• A portfolio showing the full process: research, flows, prototypes, testing and final screens.
• Skill in Figma and familiarity with testing tools such as Maze or UserTesting.
• Ability to work with design systems and hand over clean files to engineers.
• Clear communication, since much of the job is explaining design choices to non-designers.

3. Lead product designer

   Lead · SkillsFuture title

   You set the design direction for a product line and guide other designers. You work with senior stakeholders and help the organisation see what design can add.

4. Head of design

Product designer interview questions

We wrote these questions from the skills this job needs. They are not an official question bank.

1. Walk me through your design process on a recent project, from problem to launch.

   What a good answer covers

   • States the user problem and business goal at the start
   • Describes research and how it shaped the direction
   • Shows how ideas moved from sketches to tested prototypes
   • Explains handover and how the result was checked after launch

2. How do you decide between a quick usability test and a full research study?

   What a good answer covers

   • Links the method to the question and the cost of being wrong
   • Uses quick tests for specific interface doubts
   • Uses interviews or field studies to learn about needs and behaviour
   • Explains how many participants and what they need to be recruited for

3. How would you set up and maintain a design system in Figma for a team of five designers?

   What a good answer covers

   • Starts with an audit of existing screens and repeated patterns
   • Builds components with variants, plus shared colour and spacing styles
   • Documents usage rules and writes clear naming conventions
   • Sets up a process for requests and changes
   • Works with engineers so code components match the designs

4. When do you use low-fidelity wireframes and when do you build a high-fidelity prototype?

   What a good answer covers

   • Uses low fidelity early to test structure and flow cheaply
   • Moves to high fidelity when visual detail or interaction affects the result
   • Explains how to keep stakeholders focused on the right feedback
   • Gives an example where a rough version saved time

5. How would you run an unmoderated test in Maze or UserTesting for a new sign-up flow?

   What a good answer covers

   • Writes clear tasks that avoid leading users
   • Defines success measures such as completion rate and time on task
   • Uses a screener to recruit the right participants
   • Runs a pilot to catch unclear instructions
   • Reads recordings alongside numbers to find the cause of drop-off

6. How do you prepare a Figma file for handover to engineers?

   What a good answer covers

   • Uses auto layout, components and consistent naming
   • Shows all states: empty, loading, error and success
   • Adds notes on behaviour and edge cases
   • Walks engineers through the file and answers questions early

7. Have you used AI coding tools to build a working prototype? What did you do and what are the limits?

   What a good answer covers

   • Describes the prompt, the output and how it was edited
   • Uses the prototype to test an idea with users, leaving the real build to engineering
   • Notes that generated code needs review before real use
   • Explains where the tool failed and how it was handled

8. How do you measure whether a redesign actually worked?

   What a good answer covers

   • Sets a baseline before the change
   • Picks measures tied to the goal, such as task success, conversion or support requests
   • Combines usage data with user feedback
   • Describes what you do if results are mixed

1. Engineering says your design cannot be built before the sprint ends. What do you do?

   What a good answer covers

   • Asks which parts are costly and why
   • Proposes a smaller first version that still solves the core problem
   • Agrees with the product manager what moves to the next sprint
   • Keeps the full design as a documented later step

2. A usability test shows most users miss the main button on a checkout page, but the product manager wants to keep the layout. How do you respond?
