Website: getsupernal.ai
Supernal is building the operating system for businesses powered by AI employees.
AI employees are here — and they’re redefining how businesses operate. At Supernal, we turn any tedious, manual process into an AI-powered workflow, managed through a delightful interface and accessible from web to phone. Businesses can now scale faster with smaller human teams empowered by large teams of AI employees.
We believe this is a trillion-dollar opportunity. As a founding engineer, you'll help invent the infrastructure and interfaces that make it possible. Supernal has already reached multi-million dollar revenue within months, and we’re just getting started.
Why This Role Exists
We’re looking for a well-rounded, full-stack founding engineer to help us build robust AI systems and product experiences end-to-end. You’ll work directly with the founders on everything from core architecture to shipping new AI-powered features. If you’re a systems thinker, rapid builder, and care deeply about great UX and AI performance — we’d love to meet you.
🔧 What You’ll Do
• Architect and scale RAG pipelines, agent-based systems, and LLM-powered workflows
• Fine-tune large language models for structured data extraction and automation
• Build developer-friendly APIs and interfaces for web automation
• Ship product features fast — with real usage and feedback
• Work closely with product, design, and customers to build what matters
• Stay ahead of the curve on LLM tools, embeddings, orchestration, and training
• Create elegant, resilient systems that just work
🌟 Who You Are
• A full-stack engineer comfortable across Python/Django, React/TypeScript, or eager to learn fast
• A system thinker who sees architecture, UX, performance, and product as a unified challenge
• Obsessed with AI agents, LLMs, and building delightful automations
• Comfortable wearing many hats: engineer, product thinker, debugger, owner
• Thrive in fast-moving environments with a high degree of autonomy
• A natural builder: you ship, you own, you iterate
✅ Bonus Points
• Experience building LLM-based agents, fine-tuning models, or RAG pipelines
• Contributions to open-source AI/ML projects
• Experience with: TypeScript, PostgreSQL, Redis
• You've trained or fine-tuned your own model from scratch
• Worked on web automation, scraping, or structured data extraction before
✨ Why Join Supernal?
• Founding role in a rocketship startup with real revenue and real usage
• Ship fast: from idea to production in days, not months
• Autonomy: own your work, your time, and your decisions
• Remote-first across US and EU, with in-person offsites and workshops
• Competitive salary + meaningful equity
• Incredible teammates: builders, operators, musicians, filmmakers, and climbers
• Backed by invisible.co, and founded by repeat entrepreneurs
🧪 Our Interview Process
We prefer to pay you for a week to build something real with us. We believe it’s the best way to evaluate fit, working style, and what it’s like to collaborate — for both sides.
Supernal is for you if:
• You’re a deep systems thinker
• You constantly seek ways to grow yourself, your team, and the product
• You want to leverage LLMs to produce what used to take entire teams
• You care deeply about product excellence and technical elegance
• You thrive when wearing many hats and solving unstructured problems
• You value freedom and want to work from your favorite place on earth
Supernal is not for you if:
• You’re looking to clock in and clock out
• You want to be told what to do
• You prefer owning a narrow slice of the codebase
If this sounds like you — let’s build the future together.
