| Industry Usage | Pre-hospital emergency care | Pre-hospital emergency care, some hospital roles |
| Common Search/Comparison | Rle vs Paramedic |
While both Rle and Paramedic roles involve pre-hospital emergency care, Paramedics have advanced training and certifications, allowing them to perform more complex medical procedures. Rle providers typically have basic EMT certification and focus on initial emergency response. The choice depends on the level of medical intervention required in emergency situations.

About Handshake AI
Human data is the core infrastructure to AI advancement. Frontier AI labs currently improve model capabilities with various data-intensive post-training techniques. We believe that data spend for AI training will increase by 3-5x in the next few years and continue for much longer as models take on new domains. Handshake AI supports all of the frontier AI labs, working on their most complex data at the largest scale.
About the RoleWe’re hiring a Staff Software Engineer to lead the architecture and evolution of our Reinforcement Learning Environments (RLE) platform—the systems that define how frontier AI models learn real-world work.
This is a high-impact, technical leadership role responsible for system design, cross-team alignment, and setting the long-term technical direction of RLE.
What You’ll DoDefine and drive architecture for scalable, extensible RLE systems and data pipelines
Lead development of platform capabilities enabling rapid domain creation
Partner with Research, Product, and Ops to shape strategy and execution
Set standards for reliability, observability, performance, and data quality
Mentor engineers and elevate engineering excellence across the team
Identify and solve systemic bottlenecks in scaling environments and data generation
8+ years of experience in distributed systems, backend infrastructure, or ML platforms
Deep expertise in system design, data modeling, and scalable architectures
Strong proficiency with TypeScript, backend systems, and modern web stacks
Proven experience operating high-scale production systems in cloud environments
Track record of technical leadership and cross-functional influence
Experience with RL infrastructure, simulation systems, or evaluation frameworks
Background supporting applied AI/ML research teams
Experience building platform-level abstractions used across multiple teams
RLE becomes a foundational, trusted platform across teams and use cases
New domains scale rapidly with minimal engineering overhead
Systems demonstrate step-function improvements in model quality and reliability
Engineering velocity and system robustness increase across the organization
