You'll partner closely with internal teams to understand how they use the platform, debug their issues, and shape a roadmap that balances immediate needs with long-term architecture. You will: * Design and build the sandboxing platform, client library, and API surface for secure code execution across containerized and virtualized environments * Ensure strong isolation, security, and reproducibility of execution across user sessions and workloads * Optimize for cold-start latency, memory footprint, and resource utilization at scale * Drive down error rates through systematic debugging, monitoring, and proactive fixes * Partner closely with internal teams using the platform to understand their needs, debug issues, and build tooling that serves their use cases * Respond to incidents and production issues with urgency, conducting root cause analysis and implementing preventive fixes * Help develop and maintain a product roadmap for sandboxing, balancing immediate needs against long-term architectural investment * Lead architecture reviews and own projects end-to-end, from design through deployment, in fast-paced cross-functional settings, Compensation packages at Scale for eligible roles include base salary, equity, and benefits.
