About Peec AI

AI search is changing how brands are discovered and chosen. People now ask ChatGPT, Gemini, Claude and Google’s AI answers what they used to search for, and AI assistants increasingly shape the journey from discovery to purchase. Winning customers now means winning over the AI systems that influence their decisions.

Peec AI is an AI search platform that helps marketing teams understand and improve how their brands are discovered, represented, and recommended. We show them where they stand, what’s shaping it, and where to act. Since launching in January 2025, Peec AI has passed $20M ARR and 4,000 paying customers. We’re a Series A company backed by 20VC and Singular, with 100+ people across our Berlin HQ and our New York office.

What you’ll do

  • Train, test, and ship models that power Peec AI’s recommendations - helping customers boost their visibility in AI search

  • Develop algorithms that extract actionable insights from AI search behavior, creating data-driven recommendations that help brands increase their AI Search visibility

  • Own the full model lifecycle from experimentation to production deployment, working closely with engineering to integrate ML solutions into our systems

  • Design and implement data pipelines to ingest, process, and analyze large volumes of data

What we’re looking for

  • Proven backend development skills in Python with experience building APIs, data pipelines, or ML infrastructure, and familiarity with tools like FastAPI, Docker, and cloud platforms (preferably GCP)

  • Deep curiosity about how LLMs work, with the ability to reverse-engineer AI search behavior and translate patterns into actionable product features

  • Track record of taking projects from research to production in a fast-moving startup environment, with strong problem-solving skills and comfort working with ambiguous, evolving problems

  • Excellent communication skills with the ability to explain complex technical concepts to customers and stakeholders

Our Data Science Stack

  • Languages: Python, SQL

  • Libraries: Pandas, NumPy, HuggingFace, PyTorch, TensorFlow, ONNX

  • Backend: GCP, Cloud Functions, Firestore, Postgres, AlloyDB, BigQuery

  • AI Models: OpenAI, Claude, Perplexity, Gemini, Llama, etc.

Bonus Points

  • Contributions to open-source projects

  • Deployed side/hobby projects that we can check out

  • Presented research papers at top ML or AI conferences

  • Having started a company before or worked at a high-growth startup

  • Fluency in Typescript

What we offer

  • Exciting and challenging work with real impact and ownership at one of Europe’s fastest-growing Series A startups

  • Regular team events and off-sites

  • Aggressive equity compensation package

  • Paid Dinner & Uber home when working late

  • The most beautiful office space and work environment in Berlin
