Senior Software Engineer - Backend Python & AI

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 typical senior engineering role.

As a Senior Backend Engineer at JuiceLabs, you'll be a technical leader and hands-on builder rolled into one. You'll architect and build new products from zero to one, mentor engineers, and help define our technical culture—all while working directly with our co-founders on our most strategic initiatives.

You'll have genuine ownership : designing scalable distributed systems, establishing engineering best practices, leading technical decisions, and pushing the boundaries of what's possible with AI. You'll also guide and grow other engineers, helping them level up while shipping production code yourself.

We're looking for someone who brings both deep technical expertise and leadership maturity. If you're the kind of engineer who can architect a complex system in the morning, review code and mentor a teammate at lunch, and prototype a breakthrough AI feature in the afternoon—this role was made for you.

What You'll Do

Technical Leadership

• Architect and own critical backend systems and infrastructure decisions across our product suite
• Define engineering standards, code quality practices, and technical roadmaps
• Lead technical design reviews and help the team make sound architectural choices
• Identify technical debt, performance bottlenecks, and opportunities for improvement across the stack
