This is a technical leadership role for an engineer who has moved beyond experimentation and prototypes and has proven experience taking AI applications through the last mile into production . You will be responsible for ensuring AI systems are reliable, observable, secure, cost-efficient, measurable, and trusted by users. You will work closely with Product, Engineering, Design, Security, Compliance, Operations, and business stakeholders to identify high-impact AI opportunities, make pragmatic architecture decisions, and deliver production-ready AI experiences at scale. Requirements Key Responsibilities Build AI Solutions for Business Impact Design, build, and launch GenAI-powered applications including AI assistants, copilots, document intelligence, workflow automation, and decision-support solutions. Identify high-impact opportunities where AI can improve productivity, operational efficiency, service quality, customer experience, and business outcomes. Take AI applications from concept through production, collaborating with Product, Engineering, Design, Security, and business teams. Lead hands-on technical execution across application architecture, model selection, prompt engineering, retrieval, orchestration, APIs, data pipelines, and user-facing experiences. Translate business requirements into scalable and measurable machine learning and AI solutions. Establish success metrics and continuously optimize solutions based on real-world user feedback and business impact. Build Enterprise-Grade AI Systems Architect reliable GenAI applications using modern approaches such as RAG, agentic workflows, tool use, structured outputs, retrieval, grounding, and fine-tuning where appropriate. Design systems that effectively combine frontier models, open-source models, smaller task-specific models, and deterministic components based on the specific use case. Develop strong grounding mechanisms using enterprise knowledge and relevant business data. Build production systems with appropriate observability, monitoring, versioning, fallback mechanisms, security, privacy, and operational ownership. Design for reliability, scalability, latency, cost efficiency, and maintainability. Stay current with advances in AI/ML and apply emerging techniques pragmatically where they deliver meaningful improvements. Evaluation, Quality & LLMOps Define practical evaluation frameworks for GenAI applications covering accuracy, relevance, groundedness, safety, latency, cost, user trust, adoption, and business impact. Establish automated and human-in-the-loop evaluation processes for AI applications. Use LLM evaluation and observability platforms such as LangFuse, Arize, or similar tools . Monitor production performance and identify opportunities to improve model quality, reliability, and efficiency. Establish appropriate safeguards, fallback paths, and quality controls for production AI systems. Technical Leadership Provide technical leadership across the AI/ML application development lifecycle. Make pragmatic architecture and technology decisions while balancing quality, speed, security, and cost. Mentor engineers and contribute to engineering standards, best practices, and technical direction. Partner with cross-functional teams to ensure AI solutions are usable, secure, reliable, and aligned with business objectives. Take ownership of production outcomes, including launch quality, reliability, user feedback, adoption, and measurable impact. Required Experience & Qualifications 8+ years of experience building applied AI/ML-based intelligent software systems. 2+ years of practical Generative AI application experience .
