Company

hirify.global provides complete knowledge of what’s happening on blockchains through our data, services, and solutions.

What you will do

• Design and build the agent platform end to end, from the context and tool layer through the execution runtime to the interfaces that expose results to users.
• Own the skill architecture, designing how agents discover, learn about, and invoke capabilities across hirify.global's product suite.
• Build and operate sandboxed execution environments where agent-generated code runs with tenant-level security boundaries and durable file persistence.
• Ship full-stack features across frontend, backend, skill libraries, and infrastructure.
• Develop the workflow platform that lets users automate complex processes beyond single conversations.
• Drive AI quality, cost, and observability, including multi-model orchestration, context window management, prompt engineering, and tracing across multi-step agent runs.

Requirements

• Built and shipped full-stack features across frontend, backend, and infrastructure, with demonstrated ownership from design through production operation.
• Worked with LLMs in production and formed real opinions from it.
• A working understanding of how to structure what an agent knows and can do within the constraints of a context window.
• Deep backend engineering fundamentals in a typed language: concurrency, error handling, state management, and system design.
• Built or operated systems with real security constraints, tenant isolation, scoped credentials, sandboxed execution, or similar patterns where trust boundaries matter.

Nice to have

• Designed tool interfaces or capability systems for AI agents, skills, function schemas, or similar patterns for giving models structured access to external systems
• Worked with the Effect ecosystem or strongly-typed functional programming in TypeScript
• Built multi-tenant platforms or systems with enterprise security requirements
• Experience in Python library development or designing SDKs for programmatic consumption
• Worked within Blockchain, FinTech or B2B SaaS companies
