What's Freeplay?
Freeplay is the platform for software teams to ship great AI products. We give product development teams the power to test, evaluate, monitor & optimize AI in production. Our customers use Freeplay to to build better LLM features, chatbots, and agents. Already we’re helping leading software companies from growing startups to Fortune 100 companies.
Why does the world need Freeplay?
Making simple requests to ChatGPT is easy. But that building production software around LLMs is much more challenging — especially for development teams without prior AI experience. They're motivated to move fast through the learning curve and focus on delivering value to customers.
Freeplay streamlines this process — making it easy for teams to develop & improve production-ready AI features quickly and confidently. Our customers love that we help them save time, avoid costly mistakes, deliver better features for their customers, and empower their entire team (engineers & non-engineers alike) to ship faster together.

Your Mission
First and foremost, you'll be a core member of our engineering team, working across our entire stack. While you bring deep applied AI expertise, this is fundamentally a full stack engineering role where you'll contribute broadly to our platform's development and use your AI experience to guide and impact what we build.
Architect AI-first systems: Design and implement robust architectures for AI-powered features, focusing on things like evaluation frameworks, testing harnesses, and monitoring systems that ensure reliable production deployment of LLM-based features.
Drive AI development practices: Define and implement best practices for prompt engineering, evaluation, and testing methodologies. Stay at the forefront of emerging techniques in AI development, bringing insights from academic research into practical engineering solutions.
Shape developer experience: Design and build intuitive APIs, workflows, and tools that make complex AI testing and evaluation accessible to developers without AI/ML backgrounds. Draw from your experience with existing AI frameworks and tooling to create delightful developer experiences that help teams ship confidently.
Build evaluation infrastructure: Create comprehensive testing and evaluation frameworks that enable teams to measure, compare, and optimize their AI features across multiple dimensions including accuracy, reliability, toxicity, and performance.
Build alongside the founding team: Work hand-in-hand with our founding team to ideate, prototype, and deliver innovative solutions that address user needs and create value for our customers.
Shape our engineering culture & process: Implement rigorous testing, code reviews, and continuous integration processes to maintain high-quality, production-ready code while minimizing technical debt.
