Software Engineer, AI Agents

About this role

Blockit is hiring a Software Engineer to build AI agents that autonomously coordinate meetings and scheduling across multiple people and timezones. You'll own the core intelligence of the platform, designing agent architectures, refining prompts, building evaluation frameworks, and shipping new capabilities as the system handles increasingly complex coordination problems.

What you'll do

• Design and iterate on agent architectures for autonomous scheduling coordination
• Write and refine prompts for orchestrator and sub-agent systems
• Build and maintain evaluation frameworks to measure agent quality and catch regressions
• Debug agent failures and understand why decisions or interpretations went wrong
• Implement new agent capabilities as user needs and model improvements evolve
• Instrument and analyze agent behavior to identify patterns and failure modes

What they're looking for

• Production software development and ownership (2+ years)
• Backend engineering across the stack
• LLM systems and prompt engineering
• Agent architecture design and evaluation
• Debugging and systems analysis
• Clear technical communication
• Python or similar backend languages
• Testing and instrumentation
