Job Title

Senior Software Engineer - Agentic AI Systems

Job Description

About the Role

  • We are seeking an AI Engineer to design, implement, and deploy advanced agentic AI systems.
  • In this role, you’ll build production-ready AI agents that can reason across multiple steps, leverage a mixture of proprietary models, integrate with semiconductor design tools, and operate autonomously over a long period of time.
  • You’ll work with state of the art frameworks to create pipelines that combine LLM-based reasoning, knowledge grounding, and multi-agent orchestration.
  • This is a high-impact role where you’ll partner with research and engineering teams to translate cutting-edge chip design workflows into reliable, scalable agentic solutions for real-world use cases.

Key Responsibilities

  • Build Agentic Systems – Implement multi-step reasoning agents with advanced memory, Retrieval-Augmented Generation (RAG), and integrations to tools, databases, and APIs.
  • Evaluate and Optimize Agent Performance – Define and implement evaluation pipelines for agentic systems, including success/failure classification, grounding accuracy, reasoning robustness, tool-use reliability, and long-horizon task completion. Use metrics and benchmarks to continuously improve performance in production environments.
  • Orchestrate & Optimize – Design supervisor/sub-agent patterns, enable coordination across agents, and apply best practices for robustness, performance, and scalability.
  • Deploy & Evolve – Deliver production‑grade agentic AI workflows on cloud platforms (AWS preferred), monitor and evaluate agent performance, and continuously fine‑tune for quality and efficiency.
  • Collaborate & Translate – Work with product managers, researchers, and engineers to transform complex chip design workflows into agent‑driven, end‑to‑end solutions.

Desired Skillset

Agentic AI Systems

  • Hands‑on experience with multi‑agent orchestration and supervisor patterns.
  • Familiarity with LangChain, LangGraph, LangSmith, or similar frameworks.
  • Knowledge of RAG pipelines, memory management, and evaluation of agent performance.

Evaluation and Optimization

  • Familiarity with agent evaluation frameworks (e.g., LangSmith evals, benchmark datasets, unit tests for agent workflows).
  • Experience designing custom evaluation metrics for reasoning steps, tool use correctness, and RAG pipeline performance.
  • Ability to balance automatic evaluation (synthetic benchmarks, self‑play) with human‑in‑the‑loop evaluation for complex workflows.

Cloud & Infrastructure

  • Strong software engineering foundation with experience in cloud environments (AWS preferred).
  • Knowledge of containerized deployment and backend integration.

Programming & Development

  • Proficiency in Python; experience with backend systems and API integration.
  • Familiarity with modern software engineering practices (GitHub, CI/CD pipelines, testing frameworks).

Required Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Software Engineering or a related field.
  • 5‑10 years of experience in software development in cloud environment.
  • 2+ years of experience with hands‑on experience building and deploying production‑grade agentic AI systems with real‑world applications.
  • Solid working knowledge of Retrieval‑Augmented Generation (RAG), agent performance evaluation, and hands‑on experience with LangGraph and LangSmith platforms.
  • Proficiency in Python and familiarity with backend cloud services (preferably AWS).

Preferred Qualifications

  • Contributions to open‑source AI projects or frameworks.
  • Experience with multi‑agent orchestration patterns at scale.
  • Knowledge of reinforcement learning, planning algorithms, or autonomous reasoning.
  • Track record of deploying agentic AI systems in production at scale.

What We Offer

  • The chance to work on state‑of‑the‑art AI systems that push the boundaries of autonomy and reasoning.
  • A collaborative environment where engineering meets research.
  • Competitive compensation and equity in a fast‑growing AI startup.
  • A culture that values ownership, curiosity, and technical excellence.

Featured Benefits

  • Medical insurance
  • Vision insurance
  • Dental insurance
  • 401(k)
