Staff Software Engineer
Role Overview
The Staff Software Engineer at IC4 designs, builds, ships, and operates model-driven capabilities for HR Service Delivery.
The role focuses on agentic and conversational experiences that interpret intent, reason over HR context, invoke tools, and act on a user's behalf.
This is not a machine learning or AI research role and does not involve training foundation models.
The role differs from traditional full-stack engineering because runtime behavior is probabilistic and requires large-scale behavioral evaluation.

Role Summary
The Staff Software Engineer at IC4 designs, builds, ships, and operates model-driven capabilities for HR Service Delivery.
The role focuses on agentic and conversational experiences that interpret intent, reason over HR context, invoke tools, and act on a user's behalf.
This is not a machine learning or AI research role and does not involve training foundation models.
The role differs from traditional full-stack engineering because runtime behavior is probabilistic and requires large-scale behavioral evaluation.
AI-Native HR Capabilities
- Build agentic capabilities across the employee lifecycle, including intent interpretation, multi-step reasoning, tool invocation, and user-authorized actions.
- Develop guided service selection, natural-language case creation and enrichment, case status, change handling, triage, routing, and deflection.
- Support payroll and benefits inquiries, eligibility and entitlement questions, and agent-driven onboarding, transfer, and offboarding events.
Autonomous Workflows
- Decompose HR processes into executable steps and decision points.
- Define where autonomy is appropriate, where human checkpoints are required, and how exceptions, retries, and hand-back are handled.
- Require structural human decision points for changes to pay, employment status, restricted records, employee relations, and investigations.
Instructions and Tools
- Write, structure, and version system instructions, role definitions, tool descriptions, guardrails, and escalation paths.
- Maintain shared instruction and tool-description surfaces under code review, source control, and regression coverage.
- Provide upgrade-safe extension points and versioning discipline because customers configure and extend the product on their own instances.
Evaluation and Testing
- Design and operate evaluations using golden datasets and multi-turn conversation suites.
- Use model-as-judge scoring calibrated to human review, CI gates, and drift detection to make changes safe.
- Treat automated evaluation as a first-class engineering activity for nondeterministic behavior.
HR Data and Correctness
- HR workflows require accuracy for payroll, benefits, leave, statutory entitlements, and jurisdiction-specific policies.
- Access boundaries must be enforced in retrieval and tool layers so users cannot receive records they are not entitled to read.
Requirements
- Own AI design decisions across the HR Service Delivery domain at IC4 scope.
- Own the correctness of capabilities that ship, whether produced by a person or an agent.
- Treat agent instructions, tool descriptions, guardrails, and escalation paths as versioned engineering artifacts under code review and source control.
- Design correctness and access boundaries for sensitive HR data and restricted records.
