• Collaborate closely with product, design, ML, and scientific teams to translate user needs into technical solutions
• Make architectural decisions that balance speed, scalability, reliability, and developer velocity
• Improve system performance, reliability, and observability as usage and data volumes grow
• Write clean, maintainable, and well-tested code that sets a high bar for quality
• Mentor junior engineers and contribute to raising the overall engineering bar
• Participate in technical planning, code reviews, and ongoing platform evolution
