About the role
As part of AfterQuery’s engineering team, you’ll have end-to-end ownership over projects that push the frontier of AI evaluation. This is not a narrow role.
One week you might prototype a new RL environment from a research paper, the next you’ll be deploying distributed experiments on Kubernetes, and the week after you’ll be improving the reliability of our Next.js dashboards or building a Kafka pipeline for annotator analytics.
What You’ll Do
- Design and build scalable systems: RL environments, APIs, and human-in-the-loop platforms.
- Collaborate across research, product, and design to ship features quickly.
- Write clean, maintainable code and contribute to documentation.
- Participate in code reviews and design discussions
- Solve real-world scalability and reliability challenges.
- Contribute to the core infrastructure powering data and evaluation for leading AI labs.
