## Job description

OUR MISSION IS TO AUTOMATE KNOWLEDGE WORK. THE FIRST STEP IN OUR JOURNEY IS TO BUILD THE BEST TOOL FOR TEAMS TO BUILD AGENTS.

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.

## EQUAL OPPORTUNITY

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.

## About Sim

## Company Overview
- **One-liner**: Sim provides an open-source visual workspace for developers to build, deploy, and manage AI agent workflows by connecting LLMs to tools like Slack, Supabase, and Gmail.
- **Entity Type**: Private (YC Spring 2025, Series A funded)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2025
- **Founders**: Emir Karabeg (Co-Founder & CEO) and Waleed Latif (Co-Founder & CTO)

## Core Business
- **Industry**: Technology – AI Agent Infrastructure / Developer Tools
- **Target customers**: B2B – technical teams, individual developers, and enterprises building AI agent workflows.
- **Mission/Purpose**: “Build, deploy, and manage AI agents” from a single workspace, making agent creation as visual and intuitive as possible.

## Products & Services
- **[Sim Studio](https://www.sim.ai/)**: An open-source drag-and-drop canvas to design, test, and deploy AI agent workflows. Supports hosted and local LLMs, granular tool use, structured output, and deployment as APIs, scheduled runs, or chat interfaces. Integrates with 1,000+ apps (Slack, Supabase, Pinecone, Gmail, etc.).
- **Pricing Tiers**: Free (trial), Pro ($25/month), Teams ($100/month), and Enterprise (custom). Each tier scales credits, file storage, table rows, workspaces, execution limits, and log retention. Enterprise adds SSO/SCIM, SOC2 compliance, self-hosting, and dedicated support.

## Market Standing
- **Valuation**: Not publicly disclosed; raised a $7M Series A (led by Standard Capital with 10 investors) and a $500K pre-seed from Y Combinator (July 2025).
- **Key Metric**: Total funding ~$7.5M; 70,000+ developers using the platform; 26,000+ GitHub stars in eight months; 4,646 LinkedIn followers (610% YoY growth).
- **Notable Investors/Partners**: Y Combinator (lead pre-seed), Standard Capital (lead Series A), and a network of 1,000+ integrated apps (Supabase, Pinecone, Slack, etc.).
- **Growth Signals**: Headcount grew 866% YoY (from ~1 to 7 employees), active job postings up 150% quarterly, and the company expanded presence to Brazil. Recently launched enterprise-grade features (SSO, SOC2, self-hosting).

## Competitive Advantages
- **Open-source + visual canvas**: Combines the flexibility of open-source agent frameworks with a Figma-like drag-and-drop UI that eliminates boilerplate code.
- **Rapid adoption**: Among the fastest-growing developer tools on Y Combinator’s roster (Spring 2025 batch), with strong community engagement.
- **Broad integrations**: Pre-built connectors to 1,000+ tools and support for any LLM (including local via Ollama).
- **Founder-market fit**: Both founders have deep technical backgrounds (UC Berkeley NLP/CS, Amazon infrastructure at scale) and prior startup experience.

## Strategic Focus
- **Enterprise readiness**: Investing in compliance (SOC2, SSO, SCIM) and self-hosting to capture larger organizations.
- **AI workforce management**: Expanding “AI command center” capabilities to orchestrate multiple agents, manage shared workspaces, and monitor runs.
- **Open-source community**: Continuing to grow the GitHub repository and developer ecosystem to drive adoption and contributions.

## Why Work Here
- **Early-stage impact**: Join a 7-person team where every employee shapes product, culture, and direction.
- **High growth trajectory**: 866% headcount growth in one year, rapidly scaling user base, and fresh Series A funding.
- **Compensation & equity**: Competitive base salaries ($120K–$220K) plus meaningful equity (0.20%–1.20% depending on role).
- **Location & culture**: Based in San Francisco; likely in-office/hybrid given small team. Founders emphasize collaboration (“build agents together in real-time”).
- **Technical pedigree**: Surrounded by engineers from Amazon, UC Berkeley, and prior YC startups; work on cutting-edge AI infrastructure.
