We are seeking a senior Generative AI Systems Expert with 8+ years of deep engineering experience to architect production-grade AI systems (RAG pipelines, fine-tuning, prompt optimization, inference scaling). This is a specialized Individual Contributor role for a production-focused builder who owns the AI implementation end-to-end—from initial architecture to deployment, optimization, and evaluation. While your primary mastery lies in building and scaling robust LLM applications, you possess a solid, rigorous engineering mindset. Experience or strong familiarity with Quality Assurance (QA), Test Automation, and AI evaluation frameworks is preferred to ensure our systems behave reliably and deterministically at scale. You are not just implementing off-the-shelf models; you are designing complex retrieval systems, optimizing inference pipelines, evaluating model trade-offs, and building systems that reliably serve millions of transactions. What We’re Looking For (Who You Are)
• AI Systems Architect (Core): 4+ years of dedicated experience building and shipping LLM systems in production. You understand model selection, RAG architecture, fine-tuning strategies, inference optimization, and cost management. You make pragmatic trade-offs between accuracy, latency, and cost.
• Production-Focused Builder: You've shipped LLM systems at scale. You are deeply comfortable with tokenization, context windows, vector database optimization, handling hallucinations, and system failures.
• Independent Operator: You own AI features end-to-end—from problem definition through evaluation, deployment, and production monitoring.



You unblock yourself and make good decisions with incomplete information.
• Quality & Evaluation-Minded (Highly Valued Plus): You possess a rigorous engineering background with a strong appreciation for testing. You understand how to handle non-deterministic outputs through deterministic test design, evaluate model performance (F1, precision, recall), and build/use automation frameworks to prevent regressions.
• Team Amplifier: You mentor engineers on AI best practices, participate in code reviews, and help scale GenAI adoption across the organization.
• Continuous Experimenter: You A/B test approaches, iterate based on production data, and stay current with the rapid evolution of LLMs. GenAI Core & Architecture (Must-Have)
• LLM Ecosystem: Deep experience with LLM APIs (OpenAI, Anthropic, Hugging Face), model trade-offs, and selection.
• Retrieval: RAG pipeline architecture and vector databases (Pinecone, Weaviate, FAISS).
• Optimization: Prompt engineering, fine-tuning (PEFT/LoRA), and inference optimization.
• Operations: Cost/latency management, hallucination detection, and mitigation.
• Advanced Patterns: Agentic patterns, multi-step reasoning, and building for reliability under uncertainty.
•

Education:




Degree in Computer Science, Mathematics, or equivalent professional experience. A practical portfolio demonstrating GenAI/ML implementation is valued highly. Testing & Automation (Good-to-Have)
• Domain Expertise: 5+ years in the QA/Testing domain.
• AI-Specific Validation: Regression testing for models, hallucination testing, bias detection, and mocking LLM APIs.
• Deterministic Design: Handling non-deterministic AI outputs through deterministic test frameworks.
• Automation Suite: Proficiency in test case design (positive, negative, edge cases) and frameworks like pytest, Jest, Selenium, or Cypress.
• CI/CD: Experience integrating automated test execution into CI/CD pipelines.

Key Responsibilities
• Build: Design and implement end-to-end GenAI systems—RAG pipelines, fine-tuning strategies, and prompt optimization. Make pragmatic choices between model options, latency/cost trade-offs, and production constraints.
• Ship & Guard: Own the deployment of AI features. Architect the system to ensure reliability, scalability, and proper handling of edge cases (hallucinations, rate limits, failures) using robust validation strategies.
• Measure & Evaluate: Instrument systems with telemetry. Run A/B experiments comparing AI approaches. Establish metrics dashboards to track both system performance and model accuracy/alignment over time.
• Collaborate: Mentor engineers on AI best practices. Participate in code reviews. Help the team adopt and scale GenAI capabilities safely and effectively.
