About The Position

We’re growing our Data Science team to drive innovation in Generative AI. As a Data Scientist – Applied AI & Prompt Engineering, you will design, build, and deploy LLM-powered solutions that directly impact our products and users. You’ll work hands-on with LLMs, transformers, retrieval-augmented generation (RAG), and AI agents, collaborating with Engineering to bring prototypes all the way to production and take ownership of their ongoing maintenance, enhancement, and evolution.

Requirements

3+ years applied machine learning, with hands-on focus on NLP, transformers, or generative AI systems.
Hands-on experience with LLM-related libraries (e.g. LangChain, LlamaIndex, OpenAI API, CrewAI, or similar) and services (Azure Prompt flow, AWS Bedrock agents, or similar)
Experience designing multi-step agents that combine LLM reasoning with tool/API calls, with safeguards against errors, loops, and unsafe tool use.
Proven experience building and deploying machine learning models to production (API, batch, or streaming).
Fluency in Python, with clean, modular, production-grade code practices.
Strong ability to design and analyze ML experiments; track performance using metrics, not gut feel.
Ability to develop, deploy and monitor AI-powered applications in cloud environments (e.g. AWS, Azure, GCP) using APIs, batch, or streaming architectures. Familiarity with containerization, versioning, and CI/CD.
Experience implementing privacy, bias mitigation, safety guardrails, or related practices.

Nice To Haves

Degree in Computer Science, Data Science, Engineering, or a related field (or equivalent experience).
Expertise in transformer-based models and LLM architectures.
Ability to bridge rapid prototyping and production deployment — you own what you build through to live systems.
Strong collaborator who thrives at the intersection of DS + Engineering.

Responsibilities

Architect and implement production-ready AI solutions involving LLMs, transformer-based models, retrieval systems, agentic workflows, and AI agents for generative tasks and automation.
Design and iterate on prompts, workflows, and RAG pipelines to improve accuracy, cost-efficiency, latency, and safety.
Design and build multi-step agentic systems that break down complex tasks, invoke external tools or APIs, manage state, and handle reasoning chains robustly.
Deploy models and GenAI pipelines in production environments (API, batch, streaming), ensuring reliability and scalability.
Build and maintain evaluation frameworks to measure model grounding, factuality, latency, and cost.
Develop and integrate guardrails (e.g., prompt-injection protections, content moderation, output validation), and safeguards for agent loops (e.g., loop prevention, tool call limits, state validation).
Collaborate cross-functionally with Product, Engineering, and ML Ops to deliver high-quality AI features end-to-end.
