What you will do

• Design and implement agent-facing and developer-facing integrations for Application Modernization Platform services, including tool definitions, API clients, and adapters.

• Propagate authentication, authorization, and tenant context securely across integration boundaries.
• Build observability for agent-driven traffic through structured logs, traces, latency and failure metrics, and diagnostics.
• Write production code and unit, integration, and end-to-end tests, including tests for nondeterministic model behavior; diagnose failures across service, tool, and model boundaries.
• Contribute to shared SDKs, command-line tools, and agent frameworks; collaborate on scoped initiatives, reviews, technical discussions, mentoring, and interviews.

Nice to have

• Experience with the Model Context Protocol or a comparable agent-to-tool integration standard.
• Experience shipping developer tooling such as CLIs, SDKs, or local servers for customer-managed environments.
• Familiarity with application modernization, relational databases, hirify.global, or automated code transformation.
• Experience supporting customers or field teams with integration and deployment issues.
• Experience mentoring engineers or interns and contributing to technical hiring.
