- Design, prototype, and ship to production agentic AI solutions, including multi-agent systems using frameworks like LangGraph.
- Implement an evaluation framework to measure model quality on offline test sets and build dashboards to track improvements over time.
- Lead and contribute to experimentation by implementing metrics, A/B tests, and monitoring, helping to harden prototypes for reliable rollouts.
- Collaborate with senior engineers and cross-functional partners to select the right technologies, participate in code reviews, and share best practices.
- Summarize research findings and model evaluations into clear write-ups and demos for the team and cross-functional stakeholders.
- Stay current on emerging agentic AI paradigms, implement paper-inspired proofs of concept, and contribute insights to the team roadmap.
What We're Looking For
- Master’s degree or above, or equivalent experience in Computer Science, Electrical Engineering, or a related field, with an emphasis on building products using frontier multimodal LLMs.
- Expertise in agentic AI, pretraining, fine-tuning, and reinforcement learning of large language models.
- 3+ years of hands-on experience building large-scale, high-impact solutions.
- Experience deploying and scaling AI services capable of handling hundreds of millions of daily interactions with high availability, low latency, and robust fault tolerance.
Nice to Have
