Software Engineer - San Francisco - Magic Inc
Description
Software Engineer
Magic's mission is to build safe AGI that accelerates humanity's progress on the world's most important problems. We believe the most promising path to safe AGI lies in automating research and code generation to improve models and solve alignment more reliably than humans can alone. Our approach combines frontier-scale pre-training, domain-specific RL, ultra-long context, and inference-time compute to achieve this goal.
About The Role
As a Software Engineer at Magic, you will work on core systems or product surfaces that directly determine model capability and user experience.
This role can map onto Pre-training Data, RL Research & Environments, or Product, depending on background and strengths. Across all placements, the expectation is end-to-end ownership: defining problems, implementing solutions, shipping to production, and iterating based on real outcomes.
Magic's long-context models introduce unique technical challenges internet-scale data acquisition, long-horizon post-training loops, and product workflows that make complex model behavior understandable and controllable. You will operate close to these constraints, building systems that are both technically rigorous and production-ready.
This role can evolve into deeper specialization in data systems, post-training capability development, or product engineering leadership, depending on strengths and interests.
What You'll Work On
Depending on team placement, you may:

Compensation, Benefits, And Perks (US):
Magic strives to be the place where high-potential individuals can do their best work. We value quick learning and grit just as much as skill and experience.
