Member of Technical Staff, DX & Data Tooling 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: We're looking for someone to lead developer experience and data tooling for our pre-training data team. This person will build internal tools and infrastructure that make the team more productive—dashboards, CLIs, data exploration UIs, and the systems that tie them together. The role is focused on DX and tooling—we're looking for someone who genuinely loves hacking on things, shipping fast, and tinkering. What you might work on: Lead tooling efforts across the stack: build systems, continuous integration, CLI tools, and internal web UIs Build internal tools for exploring datasets, labeling data, reviewing data quality, and tracking data inventory Improve ergonomics of data infrastructure—IO patterns in Ray/dataflow jobs, dataset tracking, pipeline observability Identify opportunities by engaging with the team, listening to pain points, and proactively improving workflows Raise the bar on code organization, packaging, and engineering best practices What we’re looking for: Nice-to-Haves Strong software engineering fundamentals Genuine care for developer experience and best practices in code organization Good communicator who engages with teammates to understand their needs Bias toward action—sees something broken and fixes it Based in San Francisco (this role is in-office) Ideal Background (in rough priority order) Open source contributor — someone in the mold of tools like Ruff, uv, or similar developer-facing projects Build systems / CI experience — has written or maintained build systems, CI pipelines, or developer tooling at scale Startup product dev — comfortable moving fast, shipping throwaway prototypes, iterating quickly Not Required Deep ML/AI expertise (this is a tooling role, not a modeling role) Prior experience specifically in "data engineering" pipelines—we care more about tooling instincts than domain experience Why This Role You'll have significant ownership over how a high-performing team works day-to-day. The scope is broad, the feedback loops are fast, and the work directly impacts how quickly we can move on core research and data efforts. Compensation, benefits, and perks (US): Annual salary ranges between $200K - $550K based on experience Equity is a significant part of total compensation, in addition to salary 401(k) plan with 6% salary matching Generous health, dental and vision insurance for you and your dependents Unlimited paid time off Visa sponsorship and relocation stipend to bring you to SF, if possible A small, fast-paced, highly focused team 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. Our culture Integrity. Words and actions should be aligned Hands-on. At Magic, everyone is building Teamwork. We move as one team, not N individuals Focus. Safely deploy AGI. Everything else is noise Quality. Magic should feel like magic
