**Short Summary** : We are building Generative AI Platform to enable ML and AI OPs capabilities to help Data scientists and ML engineers at Target to implement Generative AI solutions at scale. It encompasses building the RAG, model garden, experimentation, iteration, monitoring, explainability, and continuous improvement of the entire lifecycle. You will be part of a team building scalable applications by leverage latest technologies. Connect with us if you want to join us in this exiting journey.ThinkTank platform is a self-serve platform for Developers to safely experiment, build, deploy, and monitor GenAI-powered applications at Target. The platform is made up of many different tools and services, so developers don't have to manage things like model access, grounding capabilities, safety and quality assessments on their own. ThinkTank is driven by a set of pillars that represent the key values we want to support for Target Tech teams in building GenAI applications through all phases of the product lifecycle. **As a Lead Engineer, you’ll take the lead as you…** You will build applications for Target’s Generative AI Platform to enable capabilities to help data scientists, engineers at Target . You will be part of a team building highly scalable, event driven applications and leverage technologies. You have to understand Target's business and technical environments, resolve complex business challenges via technical solutions as well as be a significant code contributor, manage overall software development cycle, drive best practices and ensure development of high-quality code. You will drive resolution of technology roadblocks including code, infrastructure, build and deployment with a strong sense of ownership and advocate for technologies, frameworks, design patterns, and development best practices while ensuring all code adheres to platform, development, compliance & security standards. The Lead Engineer is a practitioner of rapid prototyping and Agile, DevOps, CI/CD, test-driven development and stays current with new technology to be able to assess viability and applicability to Target's business and technical environments. **Technical skills** : Python, Java, SpringBoot, API development, Micro services, Generative AI application development experience, LLM, LanchChain, LangGragh, prompt engineering, fine tuning, RAG, Postgres, NoSQL, Kafka, Docker, CICD, **Requirements** : • Degree of 4 year or above • 8+ years of software development experience • Experience engineering applications for the JVM.
