Software Engineer, Early Career (AI)

Notion is a collaborative AI workspace where teams and agents think together. The Early Career AI Engineer will help build AI-powered features using LLMs, embeddings, and related technologies, while contributing to product engineering, model and systems engineering, or evaluation and quality initiatives. The role includes prototyping and shipping product improvements, productionizing models and techniques, and developing evaluation and iteration processes.

Responsibilities:

• AI product engineering: building model-powered features end-to-end (UX, APIs, retrieval, orchestration, quality, and reliability)
• Model & systems engineering: improving model integration and performance (latency, cost, safety, robustness) and building the infrastructure that supports model serving and experimentation
• Evaluation & quality (evals): creating evaluation frameworks and automated/ human-in-the-loop testing to measure and improve model and product quality
• Partner with your team to prototype and ship an AI-powered product improvement
• Own a scoped productionization project: integrate a new model/technique into an existing workflow, add monitoring + guardrails, or improve latency/cost/reliability
• Contribute to evals and iteration loops: build or extend an evaluation set, run experiments, analyze results, and translate learnings into product or system changes
