Design Engineer Intern

Simular; Singapore; On-site; SGD 60,000 - 100,000; Full time

Job summary

Simular is seeking a hands-on designer to shape end-to-end product surfaces for agent experiences. You’ll take concepts from idea to shipped interfaces, collaborating with engineers and researchers to ensure clarity, trust, and delight.

You’ll prototype in HTML/CSS/JS or React, use Figma for visuals, and contribute to a shared design system. Expect lightweight user testing, fast iterations, and a strong emphasis on craft, motion, and responsive states.

Qualifications

• Bachelor's or Master's in Design, HCI, or related field.
• Portfolio showing original thinking and design craft.
• Fluent in Figma; comfortable prototyping interactions and motion.
• Ability to build working prototypes with HTML/CSS/JS or React.

Responsibilities

• Design end-to-end product surfaces for agent experiences.
• Explore interaction models for observing, guiding, and interrupting agents.
• Build working prototypes in code to test ideas early.
• Use AI tools to accelerate moving ideas to running demos.
• Run lightweight user testing and translate learnings into design decisions.
• Contribute to and maintain the design system for consistency across the product.
• Collaborate closely with engineers to ensure designs survive implementation.
• Care about craft: spacing, motion, states, and visual details.

Job description

Where multiple locations are listed for this role, the position may be based in any of those locations, with priority determined according to the order of listing.

Designing for autonomous agents is genuinely unsolved. When software acts on its own, the usual patterns stop working: how does someone watch an agent, trust it, correct it, or take back control? There\'s no established playbook, which makes this an unusually interesting place to design.

You'll work on real product surfaces that ship to users, with the support of an experienced team.

What you\'ll do

• Design end-to-end product surfaces for agent experiences, from concept through shipped interface

• Explore new interaction models for how people observe, guide, and interrupt autonomous agents

• Build working prototypes in code, not just clickable mockups, so ideas get tested against reality early

• Use AI tools aggressively to compress the distance between an idea and something running

• Run lightweight user testing and turn what you learn into design decisions

• Contribute to and help maintain our design system for consistency across the product

• Work closely with engineers so your designs survive contact with implementation

• Care about craft: spacing, motion, states, and the details most people never consciously notice

You might be a fit if

• You're pursuing a Bachelor\'s or Master\'s degree in Design, HCI, or a related field, or equivalent experience

• You have a portfolio showing original thinking, not just competent execution of familiar patterns

• You're fluent in Figma and comfortable prototyping interaction and motion

• You can build what you design: comfortable with HTML/CSS/JS or React, or you vibe-code your way to a working prototype

• You're AI-fluent: you use AI tools daily in your design and building workflow, and you have a point of view on where they help and where they don\'t

• You can explain why you made a decision, not just present the outcome

• You're comfortable with ambiguity and can push a direction forward without a detailed brief

• You give and receive critique well

Bonus: motion design, experience designing for AI products, or a shipped side project people actually use
