In this senior role, you will drive the development of generative AI (GenAI) solutions. You will provide technical leadership across teams to define and enforce best practices, bring a product-driven mindset, and ensure our GenAI platforms and applications are robust, scalable, and aligned with business needs. This role requires a hands-on leader with a passion for AI innovation, strong mentorship skills, and deep expertise in Python, LangChain, Azure cloud services, and vector databases.
Key Responsibilities:
Technical Architecture & System Design
Work with architects to design and implement core components of GenAI systems, including LLM agent orchestration, retrieval-augmented generation (RAG) pipelines, prompt-engineering frameworks, and model fine-tuning workflows. Make sound architectural decisions, evaluate alternative approaches, and ensure solutions meet enterprise expectations for performance, reliability, scalability, and security.
Hands-on Solution Development
Lead end-to-end development of GenAI solutions from concept through production. Prototype and build critical components in Python, integrate large language models and frameworks such as LangChain, and operationalize embeddings, vector stores, and RAG pipelines. Ensure AI systems address real-world use cases and deliver measurable business impact.
Cross-Functional Collaboration
Drive cross-team alignment, influence architectural decisions across departments, and champion adoption of AI in high-value use cases. Ensure GenAI initiatives remain aligned with the broader enterprise technology strategy.
Technical Leadership & Mentorship
Provide senior technical leadership and mentorship to engineers at all levels. Conduct code reviews, support pair programming, guide architectural discussions, and lead micro-teams or pods to deliver complex features. Foster a collaborative, inclusive, and learning-oriented engineering culture.
Engineering Excellence
Establish and enforce coding standards, rigorous testing practices, and high-quality documentation. Drive consistent adoption of CI/CD pipelines and strengthen secure coding practices. Maintain high test coverage and ensure solutions meet enterprise expectations for security, reliability, performance, and compliance. Apply strong engineering fundamentals end-to-end by writing clean, maintainable, well-tested code; following modern design patterns; implementing robust unit, integration, and functional tests; and ensuring operational reliability through monitoring, observability, and resilient error handling. Review code developed by other engineers and provide actionable feedback to ensure adherence to best practices.
Agile Project Leadership
Lead and actively participate in Agile/Scrum ceremonies, including sprint planning, backlog refinement, and retrospectives. Manage work through Jira, optimize deployments via CI/CD pipelines (for example, Jenkins), remove execution blockers, and maintain alignment across teams to ensure timely delivery of GenAI features.
