Description

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 DevOps/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
• Bachelor’s or Master’s degree in Computer Science, Engineering, Mathematics, or related technical field.
• 3–5 years of experience building and deploying AI/ML‑powered applications in production, ideally in consumer, ecommerce, or retail environments.
• Strong programming skills in Python and experience with modern ML/AI frameworks (PyTorch, TensorFlow, 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 (SageMaker, 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
