You will partner with our clients and other West Monroe team members on transformational AI projects. On client projects, you will work with a Technical Architect to gather technical requirements, define platform and integration design, and perform the configuration/development of the solution in a team environment. This role will focus on building intelligent agents and advanced prompting systems that enhance automation, decision-making, and user experience with our clients. You will collaborate closely with product, engineering, and design teams to architect and own AI-driven solutions. Principal AI Software Engineers in our TechEx practice have these primary responsibilities: * Functional Responsibilities: * + Collaborate with team members to design and develop software applications across multiple languages. + Collaborate with clients to understand their business needs. + Use an Agile approach to iteratively deliver products. * Internal Responsibilities, * Design, build, and deploy AI agents that automate workflows and enhance platform intelligence. * Develop advanced prompting strategies for LLMs (e.g., Claude, GPT, Gemini) to support engineering and product use cases. * Own the end-to-end lifecycle of AI features-from ideation and prototyping to production deployment and monitoring. * Collaborate with cross-functional teams to align AI capabilities with business goals and user needs. * Integrate AI solutions with existing backend services and APIs (e.g., Java, React, AWS). * Ensure scalability, security, and compliance of AI systems. * Stay current with emerging AI technologies, frameworks, and best practices. * Leverage AI tools to accelerate analysis, synthesize complex information, and support data-driven recommendations for clients, exercising sound judgment in evaluating outputs. * Apply AI technologies (e.g., generative AI, automation tools, data models) to enhance insights, improve delivery efficiency, and elevate the quality of client outcomes.
