Prompt Engineer

About the Role: We're looking for a skilled Prompt Engineer to join our AI team and shape how our products communicate with large language models. You'll sit at the intersection of linguistics, engineering, and product - crafting the instructions that make AI genuinely useful. You have a genuinely curious, inventive mindset - you explore model behavior with a habit of probing edge cases, questioning assumptions, and regularly surfacing insights the team didn't know to look for.

As a Prompt Engineer, you will design, test, and iterate on prompts that drive our AI-powered products. Working alongside product managers, engineers, and designers, you'll be responsible for the quality, consistency, and safety of all LLM outputs - from customer-facing features to internal automation pipelines.

Responsibilities:

Partner with product, engineering, and design to rapidly prototype and iterate on prompts for production LLM applications across diverse use cases. Turn around prompt revisions within tight cycles, maintaining quality without sacrificing speed
Test and iterate on prompts systematically to improve accuracy, consistency, speed and output quality
Build prompt templates and libraries that enable reusable, scalable AI solutions across the organization
Document prompt patterns, techniques, and findings for team knowledge sharing
Evaluate AI model outputs against quality criteria and implement improvement strategies
Collaborate with engineers to integrate prompts into scalable, reliable pipelines
Monitor model behaviour post-deployment, implement versioning and A/B testing strategies and respond to regressions or edge cases
Research emerging prompting techniques and apply them
Contribute to red-teaming and safety reviews to identify risks in LLM outputs

Requirements:

2+ years of hands-on experience in prompt engineering or a closely related AI/NLP role with significant focus on working with LLMS and Generative AI; demonstrated expertise in prompt engineering
Hands-on experience with tool-calling patterns, function routing, and structured output formatting in the context of agent orchestration
Systematic testing and experimentation methodologies and iteration
Creative problem-solving to find innovative solutions using AI
Understanding of token economics, context windows, and model limitations
Strong written communication skills - clarity and precision are your superpowers
Ability to document processes and communicate technical findings to non-technical stakeholders
Comfortable working in-office five days a week in a fast-paced, collaborative environment

Nice to Have

Prior work in a product-led or SaaS environment
Experience collaborating with clinicians, medical writers, or editorial teams in a publishing setting, translating domain expertise into precise, compliant LLM instructions
