Senior Applied AI Engineer

Salary: CHF 100’000 - 130’000 per year

Requirements:

• 🔍 You Should Have
• Python in your blood. LangChain, Transformers, LangSmith — we assume you’ve touched them.
• Agentic systems experience — not just chatbots, but agents that do things.
• Experience with vector search, retrieval pipelines, and structured knowledge integration.
• Comfort working across Python and Node.js.
• A hacker’s mindset with a product sense — you build fast and you build smart.
• Bonus: voice interfaces, crawling tools, observability stacks — we’ll high-five you for it.

Responsibilities:

• 🛠️ What You’ll Actually Do
• This ain’t a Kaggle playground. You’ll be:
• Integrating cutting-edge LLMs (OpenAI, Cohere, Anthropic, DeepSeek — whatever gets the job done).
• Building memory-augmented agents that feel like a boardroom genius in your pocket.
• Architecting real-world ingestion flows — markdown, PDF, structured data — the works.
• Deploying and tuning voice agents that don’t sound like awkward call center bots.
• Monitoring performance with observability tools so you know when shit breaks before we do.
• Working directly with founders and enterprise clients. No PMs shielding you from reality.

👋 Who We Are

ComplexChaos is building the AI layer for multi-stakeholder alignment — from sustainability targets to geopolitical negotiations. We’re making the impossible feel like a breeze.

Backed by Village Global (Reid Hoffman, Jeff Bezos, Bill Gates, no big deal) and a killer crew of angels from OpenGov, WhatsApp, Mural, Pactum AI, Google, Workday, and beyond, we’re turning the art of negotiation into a science powered by real-time AI agents.

We’re pre-seed, post-pilot, and ready to scale — with serious traction, real-world pain points, and no room for tourists.
