Responsibilities

When your actions lead to success:

Engineering

• Design and build machine learning and generative AI components that integrate with our data platforms and infrastructure, built for automation, reliability, and operational efficiency.
• Write clean, maintainable production code for our ML and LLM services and keep them straightforward to deploy and scale.
• Take part in the ongoing development of our existing AI solutions: implementing changes, improving the architecture, and reviewing pull requests.
• Work with large, real-world datasets, from extensive document collections to promotional product data.

Business rules and configuration

• Analyze incoming business requirements and translate them into the platform's rules and configurations.
• Work out data conventions from real feeds when stakeholders cannot fully articulate them.
• Spot conflicts between rules, propose trade-offs, and work with stakeholders to keep the overall rule system coherent.
• Configure how content is rendered and laid out so it matches each of the customers style guides and production artwork.

Prompt engineering and LLM quality

• Design and iterate on LLM prompts and few-shot examples for copywriting, brand extraction, and translation.
• Evaluate prompt and model changes systematically so quality improvements are measured, not assumed by feel.
• Maintain the curated reference data that grounds LLM outputs.

Validation and growth

• Test generated output against real data, review it with content and business stakeholders, and iterate until the results meet the bar.
• Keep learning: explore new techniques and advanced AI topics with a team that shares knowledge freely.
