This role is perfect for an early-career engineer eager to apply cutting-edge AI and machine learning tools to solve real-world problems that impact global scientific progress.

What You’ll Do:

· Build and optimize AI/ML pipelines and evaluation systems for large language models used in product search and knowledge applications.

· Develop evaluation frameworks and dashboards to measure model accuracy, latency, and user experience improvements.

· Collaborate with data engineers and product teams to preprocess, label, and integrate large datasets into AI workflows.

· Contribute to prompt tuning, accuracy testing, and continuous improvement of LLM-driven digital experiences.

Technologies:

AWS (Bedrock, Lambda, ECS, S3, OpenSearch), Python (LangChain, Hugging Face, RAGAS, PyTorch, TensorFlow), REST APIs, JSON, SQL, CI/CD (GitHub Actions), Data Visualization (Matplotlib, Plotly), LLM Evaluation (Cohere Rerank, Claude, Amazon Nova), CloudWatch, Atlassian Suite (Jira, Confluence), Sourcegraph Cody AI

Technical Development & Implementation

· Design, build, and deploy machine learning models using frameworks like TensorFlow, PyTorch, or Hugging Face.

· Support the creation of LLM evaluation pipelines for retrieval-augmented generation (RAG) systems, automating guardrail and accuracy testing across multiple dimensions.

· Assist in data preprocessing, retrieval optimization, and performance tuning using OpenSearch, S3, and AWS Bedrock.

· Develop proof-of-concept generative AI applications such as chatbots, recommendation systems, and intelligent content generation tools.

Data Engineering & Model Evaluation

· Work with large datasets to clean, preprocess, and analyze data for AI model development and evaluation.

· Generate and validate synthetic datasets using large language models (Claude, Amazon Nova, GPT) to accelerate testing and reduce manual SME review time.

· Contribute to prompt engineering, model testing, and performance analysis to ensure accuracy, reliability, and compliance in life sciences and healthcare contexts.

Collaboration & Delivery

· Collaborate with stakeholders and product teams to identify AI/ML opportunities that address key business challenges.

· Participate in sprint planning, debugging, and internal demos to communicate progress, findings, and recommendations.

· Document reusable AI components, reference architectures, and best practices to support continuous learning across teams.

Governance & Continuous Improvement

· Ensure adherence to AI governance, ethical AI, and data compliance standards (PCI, GDPR, CCPA).

· Stay up to date on advancements in AI/ML tools, frameworks, and evaluation methods; share insights and drive adoption across teams.

· Bachelor’s or Master’s degree in Computer Science, Data Science, or related field with focus on AI/ML development.

· Hands-on experience with Python and libraries such as LangChain, Hugging Face, RAGAS, or similar for model evaluation or data processing.

· Familiarity with retrieval and ranking systems (OpenSearch, S3, AWS Bedrock) and LLM-based frameworks.

· Exposure to synthetic data generation and LLM evaluation metrics (e.g., relevance, context completeness, factual accuracy).

· Understanding of cloud-based AI workflows using AWS Bedrock, Lambda, or ECS.

· Strong analytical and problem-solving skills with the ability to learn quickly and apply feedback in iterative development cycles.

· Comfortable working with cross-functional teams and presenting project outcomes to non-technical audiences.
