Sim is talent-dense. We're looking for special people who are mission-driven, passionate, and creative.
About the Role
Design engineers own the feel of Sim. Building agents is still too hard for most people, and you'll make it feel obvious. You blend design and engineering to invent the interfaces that turn a complex, powerful system into something people love to use.
You may be a fit if
• You've shipped interfaces that are both beautiful and genuinely usable.
• You blend excellent engineering with real taste for design, and a knack for making powerful tools without compromising their ease-of-use.
Compensation
$210K–$260K base plus 0.2%–0.8% equity.
Applying
If there appears to be a fit, we'll reach out to schedule 1-2 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team.
Sim is committed to creating an inclusive environment for all employees. We celebrate diversity and are committed to creating an inclusive environment for all team members. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
Skills Required
- Deep experience in React and TypeScript
- Strong UI/UX intuition

- Understanding of front-end performance and responsiveness
- Comfort working in Next.js; backend experience is a plus
- Experience with real-time systems is a plus
- Visual design skills or open-source contributions are a plus
What We Do
Sim's mission is for agents to run the world, and Sim is the primary means by which this happens. It is described as the 'Figma for AI agents', an intuitive drag-and-drop canvas where developers connect LLMs, tools, APIs, and logic blocks into complex agentic workflows.
