Job summary

TCP Software is seeking a senior software engineer to design, build, and ship agentic AI features end to end in a cross-functional agile team. You will ground agent behavior in deterministic rules, operate the LLM layer with structured outputs, and implement safe patterns for actions, including idempotent operations and immutable audit logging.

Responsibilities include developing statistical detection and baselines from workforce data, managing inference cost, latency, and model selection from

Qualifications

• 6+ years of professional software development experience, including shipping LLM-backed or agentic features to production.
• Deep production experience with C#/.NET, SQL Server, and API design in systems where correctness has financial consequences.
• Experience integrating LLM APIs into enterprise applications, with structured outputs, retrieval grounding, and evaluation-driven iteration.
• Working fluency with statistical techniques on time-series data, such as rolling baselines, outlier detection, and threshold tuning.
• The ability to understand requirements and solve technical issues without supervision, serving as a technical lead.

Responsibilities

• Design, build, and ship agentic AI features end to end, from detection and decision logic through safe action execution, in a cross-functional agile environment
• Ground agent behavior in deterministic rules engines and governed data so every agent explains its reasoning and never acts outside permitted boundaries
• Build and operate the LLM layer, including prompt architecture, structured outputs, confidence scoring, timeouts, and rules-only fallback paths
• Implement safe patterns for agent actions, including idempotent operations, undo windows, retries with backoff, and immutable audit logging
• Develop statistical detection and baseline logic that turns workforce data into ranked, explainable findings with business impact attached
• Manage inference cost, latency, and model selection from development through production
• Partner with QA on evaluation suites, shadow-mode rollouts, and the trust metrics that gate every agent capability, and mentor junior engineers along the way
• Operate independently, setting priorities and goals while continuing to learn and grow technically
• Backend: C# on modern .NET and .NET Framework in a multi-tier service architecture.
• Database: Microsoft SQL Server, including schema projects and idempotent migration scripts.
• Delivery: Docker, Jenkins CI/CD, and cloud-hosted deployment.
