We’re looking for a Data Scientist to join our tech team and help build the future of neuro‑contextual advertising at global scale.
Responsibilities
- Build production‑grade AI agent systems that interact with data, execute multi‑step workflows, and make autonomous decisions impacting business outcomes.
- Design and implement agent architectures using modern frameworks, working on multi‑agent orchestration patterns, agent delegation, and ensuring reliable execution under production constraints.
- Solve context management challenges across conversation history, tool outputs, and file attachments, implementing semantic search and retrieval systems to ensure agents have the right information to answer questions accurately.
- Integrate agents with data infrastructure, connecting them to databases and APIs in real‑time, and implement tool integration systems that enable scalable development across teams using protocols like MCP.
- Build evaluation frameworks to measure agent performance in production, taking solutions from concept to deployment, and collaborating closely with cross‑functional teams to align your work with business goals.
Qualifications
- 3‑5 years of experience building and deploying production ML systems, with hands‑on experience developing LLM‑based applications or autonomous agents using frameworks such as Pydantic AI, OpenAI Agents SDK, LangGraph, or similar.
- Strong software engineering skills with proficiency in Python and a track record of deploying services to production, including experience with async programming, API design, and production infrastructure such as Docker and Kubernetes.
- Strong academic background in fields such as Computer Science, Engineering, Statistics, Mathematics, or similar, with a focus on quantitative analysis and problem‑solving, plus understanding of retrieval systems, embeddings, or context‑management patterns.
- Hands‑on experience with end‑to‑end project workflows from design to deployment, understanding multi‑step agent workflows and tool‑calling patterns, and the ability to handle the non‑deterministic nature of LLM‑based systems.
- Proactive, entrepreneurial, and adaptable, comfortable working in a fast‑moving environment where best practices are still emerging, and committed to building reliable AI agent systems that drive measurable business outcomes.
