## Description

Handshake AI is building the infrastructure that powers how AI work gets delivered at scale. Every project our operators launch, every fellow who works on those projects, and every task that flows through our platform relies on systems built by the HAI Annotation team.

As a Software Engineer I on this team, you'll build the core platform that enables operators to configure customer projects, manage complex tasking workflows, and ensure work moves reliably through our delivery pipelines. You'll work on foundational systems that are used across the organization and serve as building blocks for other engineering teams.

This is a highly cross-functional role where you'll partner closely with operators, product managers, product designers, and engineers across Handshake AI to create scalable, extensible solutions that improve both fellow and operator experiences.

What You'll Do

 * Build and maintain backend systems that power project configuration and delivery workflows
 * Develop tools that operators use to set up and manage customer projects
 * Create scalable tasking and pipeline systems that support complex data generation processes
 * Improve fellow tasking experiences through automation and workflow enhancements
 * Design extensible platform capabilities that can be leveraged by multiple teams across Handshake AI
 * Collaborate closely with operators to understand pain points and translate operational needs into durable, efficient software solutions
 * Partner with engineers across the organization to ensure platform systems are reliable, flexible, and easy to build upon
 * Contribute to system architecture, technical design reviews, and engineering best practices
