Responsibilities

Lead the design and implementation of closed-loop multi-agent state machines, human-in-the-loop flows, and generative AI testing frameworks.

Develop distributed agent execution environments that autonomously run and self-heal end-to-end tests.

Build statistical validation, probabilistic rubric, and calibration frameworks for measuring feature quality, model drift, and non-deterministic agent behavior.

Own technical designs, reusable components, CI/CD workflow improvements, and distributed execution services.

Diagnose code, data, and infrastructure failures, resolve root causes, and mentor engineers through reviews and knowledge sharing.

Act as product owner by defining requirements, scope, success criteria, delivery plans, estimates, risks, and dependencies with stakeholders.

Evaluate current engineering approaches, including AI-assisted workflows, and measure reliability, feedback-speed, and adoption improvements.

Requirements

- 10+ years of professional software development experience.
- Bachelor’s or master’s degree in Computer Science, Software Engineering, or a related field with coursework or academic exposure to AI/ML concepts.
- Proficiency in C# or C++ and Python, with experience designing complex software systems, automated testing, and version control.




- Experience independently implementing complex software systems with interfaces, dependencies, and documented trade-offs.
- In-depth experience with LLMs, multi-agent orchestration, state machines, context and memory management, and human-in-the-loop workflows.
- Proficiency in statistical inference, hypothesis testing, variance reduction, and experimental design for probabilistic systems.
- Experience developing generative-system evaluation frameworks, including dataset curation, LLM-as-a-judge design, validation criteria, error analysis, and quantitative and qualitative metrics.
- Experience building test automation or developer tools, integrating them into CI/CD workflows, and debugging distributed systems using logs and telemetry.
