- Design and execute rigorous quantitative benchmarks to evaluate and continuously improve agentic systems and AI features.
- Partner with the product team to iterate on and refine AI systems based on user feedback and engagement metrics.
- Work closely with AI researchers to seamlessly transition experimental research outputs into robust, production-ready backend systems.
- Define, implement, and enforce best practices for AI agent quality assurance, safety, and cost control.
- Fine-tune and train LLM/ML models when off-the-shelf options are inadequate.
- Remain at the forefront of academic and industry research in LLMs and AI agents, actively identifying and prototyping novel techniques to advance our technology stack.
What You Should Have:
- Master’s or Bachelor’s degree in Computer Science, Machine Learning, Artificial Intelligence, or a related technical field.
- 2+ years of hands-on experience developing agentic systems utilizing Large Language Models (LLMs).
- 3+ years of experience building scalable, production-grade backend systems in Python (or Go, Javascript).
- 5+ years of experience in machine learning and statistics, with a proven track record of building products leveraging LLMs, ML, CV, or NLP models.
- Strong communication skills, with demonstrated experience collaborating directly with product teams to design and elevate AI-driven features.
- A proactive approach to learning, staying informed by taking an active interest in emerging AI research and industry trends.
What We Prefer
- Master’s degree or Ph.D. in Computer Science, Machine Learning, Artificial Intelligence, or a related field.
- 3+ years of specialized experience developing complex, multi-agent systems using LLMs.
- Strong product intuition and a refined taste for delivering exceptional user experiences.
- Comfort thriving in a lean, fast-moving team environment; a willingness to dive in, take bold initiative, and own complex problems.
- A genuine passion for shipping products that surprise, delight, and engage users.
- A track record of publishing research at top-tier AI/ML conferences (e.g., ACL, NeurIPS, ICML, ICLR, AAAI, EMNLP, NAACL).
