About the Cornell Lab of Ornithology
The Cornell Lab of Ornithology is a global leader at the intersection of technology and conservation. We steward over a petabyte of biodiversity data, including more than a billion bird observations and 100 million wildlife media assets, and transform it into impactful products leveraging machine learning and expert birder communities. Our work fuels widely used platforms including eBird, Merlin Bird ID—tools that connect millions of people to birds while supporting critical research and conservation action worldwide. Through partnerships with hundreds of organizations in nearly every country, our technology helps drive real-world conservation outcomes at a global scale. We’re in a period of rapid growth, tackling ambitious challenges to expand and scale our data-driven tools for an increasingly diverse and international community. It’s an exciting moment to join a team that’s pushing the boundaries of what’s possible in conservation technology—and making a measurable difference for birds and biodiversity around the world.
What will you do:
large-scale, data-intensive applications supporting global biodiversity science and conservation. This role combines engineering leadership with hands-on development of machine learning–driven systems powering Merlin Bird ID, used by millions worldwide to identify birds from images, audio, and video.
You will lead the architecture and development of distributed systems that manage and serve massive datasets—including over 100 million media assets in the Macaulay Library—and support the full lifecycle of machine learning models, from training pipelines to production deployment. This includes integrating models into web and mobile applications in both online and offline contexts.
Working across teams of engineers, bird experts, and conservation scientists, you will design interoperable systems, APIs, and data pipelines, and serve as a key technical liaison across Macaulay Library, Merlin, and eBird. You will oversee multiple concurrent projects, set technical direction, and ensure best practices in scalability, performance, and reliability.
The role includes mentoring engineers while contributing across the stack, including backend services, web applications, and machine learning infrastructure. You will also help advance cloud-based architecture and systems designed for high availability and global scale. This role is ideal for an experienced engineer who thrives in complex systems, enjoys leading teams, and is motivated to build impactful, globally scaled software for conservation.
