Your next step

Complete your application on bpinternational.wd3.myworkdayjobs.com. The employer’s form will show what is required.

Applying through Workday

  • You create an account with each employer before you can upload anything. Every Workday employer has its own account, so one sign-up doesn’t carry over.
  • “Autofill with Resume” comes right after sign-in, before the My Information and My Experience steps. Check every field it fills in those steps, since that’s what recruiters see.
  • Your application status lives in that employer’s Candidate Home, under the same sign-in.

About the role

We file this job under ML Engineer, by the work the posting describes.

ML engineers put machine learning models into products. They write the code that trains, ships, serves and monitors models so a recommendation or prediction works for real users.

Postings ask for strong Python and software engineering, a framework such as PyTorch, cloud services, and more and more often experience with large language models.

A data scientist often works out which model to build; an ML engineer makes it run reliably in production.

  • Collaborate with data engineers, product managers, and other data scientists to ensure end-to-end delivery and reliability of AI products.
  • Stay current with emerging AI techniques, models, and technologies, but prioritize practical application and delivery over experimental research.
  • Contribute to the internal knowledge base, tooling libraries, and documentation to scale data science best practices across the organization.


Job Qualifications

  • 5+ years of professional data science experience; ability to independently design and ship complex systems in production.
  • Deep experience with both classical ML models (e.g. Regression, forecasting, and basic neural networks) as well as hands on experience using large language models.
  • Strong programming skills in Python (preferred), Java, or similar languages.
  • Strong problem-solving skills and the ability to balance scientific rigor with delivery speed.
  • Hands on experience with AI/ML tools such as LangChain, Haystack, Hugging Face, Weaviate, or similar ecosystems.
  • Experience integrating machine learning models into production systems (e.g., LLMs via APIs, fine-tuning, RAG patterns, embeddings, agents and crew of agents etc.).
  • Solid understanding of software architecture, cloud infrastructure (AWS, Azure, or GCP), and modern DevOps practices.
  • Ability to move quickly while maintaining code quality, test coverage, and operational excellence. Preferred:
  • Hands-on experience with Retrieval Augmented Generation applications, AI agents and systems built around them.
  • Experience using GenAI frameworks such as LlamaIndex, Crew AI, AutoGen, or similar agentic/LLM orchestration toolkits.
  • Exposure to working with unstructured data (documents, conversations, images) and transforming it into usable structured formats.
  • Experience building chatbots, search systems, or generative AI interfaces.
  • Background in working within platform engineering or internal developer tools teams.
  • Prior experience working in an embedded (forward-deployed) team model with business stakeholders. · Experience building production grade, reliable AI applications
