Role summary:

We are seeking a highly skilled AI Engineer to design, build, and deploy production-grade AI and Generative AI solutions that power core retail capabilities across merchandising, supply chain, pricing, stores, and digital commerce. This role is deeply hands-on and focused on turning AI models into reliable, scalable, and governed products using modern data and AI platforms

Key responsibilities:

AI System Design and Engineering:

- Design and implement AI applications for retail scenarios such as product search, recommendations, personalization, content understanding, and customer/associate assistants (chat/voice).
- Translate high level product requirements into technical designs, model choices, and service interfaces that can be implemented and iterated quickly.
- Implement LLM and NLP-based solutions (e.g., retrieval augmented generation, document Q&A;, summarization, classification) for internal knowledge assistants and customer-facing experiences.
- Work with front-end and back-end engineers to embed AI capabilities into web, app, store, and internal tools, focusing on usability and performance.

Data, modeling, and evaluation:

- Partner with data engineers to access and prepare data from POS, ecommerce, CRM/loyalty, product catalogs, and supply-chain systems; design data contracts and schemas that support AI applications.
- Build and iterate on models using appropriate techniques (traditional ML, deep learning, embeddings, LLMs), balancing accuracy, robustness, and cost.
- Set up evaluation pipelines, offline metrics, and online experiments (A/B tests) to measure impact on key KPIs like conversion, engagement, attach rate, in-stock rate, and associate productivity.
- Instrument applications with logging, tracing, and dashboards to monitor quality, latency, and errors in production.

Engineering excellence:

- Develop reliable,



well-tested APIs, microservices, and jobs that run in cloud environments (AWS/Azure/GCP), using modern Dev Ops/CI/CD practices.
- Own the full lifecycle of features you build from design and implementation through deployment, monitoring, and iteration.
- Contribute to shared libraries, templates, and best practices that make it easier for other teams to build AI features consistently.
- Collaborate across time zones, maintaining clear communication and documentation for stakeholders.

Minimum qualifications:

- Bachelors or Masters degree in Computer Science, Engineering, Mathematics, or related technical field.
- 35 years of experience building and deploying AI/ML-powered applications, with hands-on exposure to agentic AI and Agent-to-Agent (A2A) systems. Experience in consumer, e-commerce, or retail environments is preferred.
- Strong programming skills in Python and experience with modern ML/AI frameworks (PyTorch, Tensor Flow, scikit-learn, Hugging Face, or similar).
- Experience with LLMs and NLP (prompt design, embeddings, vector databases, RAG) or strong willingness and demonstrable ability to ramp quickly.
- Hands-on experience with cloud platforms (AWS, GCP, or Azure), ML services (Sage Maker, Vertex AI, Azure ML) and Databricks.
- Experience building and consuming RESTful APIs, working with SQL/NoSQL databases, and deploying services in cloud environments.
- Solid understanding of software engineering fundamentals: data structures, algorithms, testing, code reviews, and CI/CD.
- Strong communication skills and ability to collaborate with cross-functional partners across time zones.

Nice to have:

- Experience in retail, ecommerce, logistics, or similar high-volume B2C contexts.
- Exposure to MLOps tools and concepts (feature stores, model registries, monitoring) and up-to-date data stacks (Spark/Kafka/Airflow/dbt).
