AI Agent Engineer – Full Stack (Remote, Pacific Time Hours)

AI Agent Engineer – Full Stack (Remote, Pacific Time Hours) About Us

Real Simple Labs is building the next generation of AI-powered tools for e-commerce brands—starting with autonomous marketing agents. Think creative strategist, designer, and media buyer in one.

Imagine a world where brands have an army of AI employees working for them 24/7—researching customer trends, creating ad narratives, generating creatives, running tests, and doubling down on what works. With every update from the AI model companies, these employees get better and better. That’s the future we’re building toward.

There’s a lot of talk about the “one-person billion-dollar company” enabled by AI—and we believe that company could very well be an ecom brand enabled by us. These founders are the best kinds of SMB: they’re tech-savvy, chasing online virality, and often early adopters. Exactly the kind of people who can benefit most from AI.

Our platform brings this vision to life—automating the entire marketing workflow, from customer research and creative concepting to scripting and generating high-performing ads.

Why This is an Incredible Opportunity

• Top-Tier Team – Work alongside engineers and marketers from Stanford, Shopify, unicorn AI startups, and leading e-commerce ad agencies.
• Backed by the Best – We’re venture-backed by Silicon Valley investors like OVO Fund, Unlock VC, Hustle Fund, and top e-commerce angels.
• Cutting-Edge AI – Build with the latest models (OpenAI, Claude, Mastra, and more) to power end-to-end workflows across research, ideation, and design.
• Viral Demand – Our preview generated 4K+ signups—brands are eager to use what we’re building.
• Salary & Equity Upside – Competitive comp with meaningful equity in a fast-growing startup.

What We’re Looking For

• 4+ years of experience as a full-stack engineer.
• Hands-on experience building agentic workflows or LLM-powered tools is a hard requirement—personal projects are great, and links to demos or repos are strongly encouraged.
• Comfortable shipping end-to-end product features across frontend, backend, and API orchestration.
• Proficient with modern web stack: React, Next.js, Node.js, Supabase, etc.
• You’ve built with OpenAI, Claude, or similar model providers.
• Strong product intuition—especially around creative tools and UX.
• Excellent communication skills, low ego, fast iteration mindset.
• Remote role, but must be available during Pacific Time hours.

Bonus Points

• Background in e-commerce, performance marketing, or design tooling
