Backend Python / AI Engineer

About JuiceLabs

Where creative engineering meets applied AI

At JuiceLabs, we’re building vertical AI-native tools that unlock fresh insights and creative superpowers for our clients in advertising, ecommerce, and beyond. We're a nimble team of founders and builders obsessed with using AI to solve real-world problems in novel ways.

The Opportunity

This isn’t your run-of-the-mill backend gig.

As a Backend Python Developer at JuiceLabs, you’ll do much more than write APIs—you’ll help shape new products from zero to one, often with AI at the core. You’ll work directly with our Cofounder/CTO and be trusted with real ownership: building scalable systems, exploring new AI tools, and rapidly prototyping ideas that can turn into breakthrough features.

We’re looking for someone who thrives on both solid software engineering and creative experimentation. If you're the kind of developer who ships fast, loves clean architecture, and gets excited about building with LLMs or automating workflows using GenAI tools—this role was made for you.

What You’ll Do

• Build Core Infrastructure: Design and implement reliable backend systems in Python (FastAPI, GCP/AWS, Postgres), with a focus on scalability, performance, and developer ergonomics.

• Experiment with AI: Use GenAI tools, APIs, and frameworks to prototype and integrate intelligent features—from simple automations to complex workflows.

• Own What You Ship: Take projects end-to-end—from ideation and design to deployment, monitoring, and iteration.

• Work Closely with Leadership: Partner with the CTO to co-create product experiences that fuse backend muscle with AI magic.

• Bring Ideas to Life: Help turn wild ideas into working prototypes, and prototypes into production. You’re not just building what's asked—you’re helping invent what comes next.

What We’re Looking For

• Python Expertise: You write clean, idiomatic Python and know your way around common backend frameworks, testing libraries, and deployment pipelines.

• Production-Ready Mindset: You’ve deployed systems in real-world environments and understand the nuances of stability, observability, and scaling. Docker, CI/CD, cloud infra (AWS/GCP)—you’re comfortable getting things live and keeping them running.

• AI Curiosity: You’ve dabbled with LLMs, tinkered with GenAI tools, or built side projects using open-source models or APIs. (Got a weird AI bot or internal GPT tool you built? Tell us!). Bonus points if you’ve run local LLMs or fine-tuned models.

• High Ownership: You take initiative, follow through, and don’t wait to be told what to do. You're comfortable with autonomy and accountability.

• Startup Energy: You like building fast, wearing multiple hats, and figuring things out on the fly.

• Product Mindset: You think in terms of user impact, not just code elegance. Bonus if you enjoy thinking about UX—even for backend services.

Why JuiceLabs?

• Impact & Influence: Work shoulder-to-shoulder with founders. It will shape our products.
• Creative Playground: Explore and build with the latest in AI. Try new ideas. Break things. Make new things.
• Fast Growth, Real Problems: Tackle meaningful challenges in ecommerce, consumer insights, and creative tech.
• Culture of Ownership: We value builders, not order-takers. If you like agency and autonomy, you’ll thrive here.
