Krystof Hilar, Co-Founder & CTO

Big Picture AI Consultants is hiring Expert Software Developer Wanted: Tiny Team. Big Upside.

We’re building a working product: an AI voice agent for restaurants that answers phones and takes orders. The prototype is already in action—but it’s only working 96% of the time. We need someone to help bring it to 100%.

You’ll be joining a lean team with product vision, business execution, and marketing muscle already in place. We need someone who can build effectively and reliably.

We’ve already wasted time on 10+ “developers” who: • Can’t answer questions directly • Don’t communicate or follow up • Ghost when it’s time to deliver • Aren’t cooperative or team players

We’re done with that. If you’re not reliable, please move on.

What We’re Looking For: • A professional developer who wants to build something once and benefit long-term • Open-minded, direct communicator • Works within agreed timelines • Handles full-stack or backend infrastructure • Experience with voice AI a plus (not required)

Opportunity: • You can work part-time at first (estimated 200 hours for initial version) • Revenue expected within 60 days after platform completion • Targeting $10M+ potential within 3 years • We’re already using tools like OpenAI, LangChain, ElevenLabs, N8N, etc. • You focus on the build. We’ll handle the rest.

Interested?
