The Crown Is Yours

As a Lead Software Engineer on our AI Platform Team, you’ll play a key role in building the infrastructure and tooling that enables product teams across the company to integrate GenAI into real-world products.

This is a hands-on role where you’ll design, implement, and deliver AI developer infrastructure - from orchestration runtimes to observability tools - that makes AI development faster, safer, and more reliable at scale.
 

What you’ll do as a Lead Platform Engineer

• Build and maintain core AI infrastructure and tooling, including runtimes, model gateways, orchestration layers, and SDKs.
• Deliver reusable components that simplify AI development workflows - such as agent orchestration (e.g., LangGraph), vector search (e.g., Weaviate or PGVector), prompt management, and model routing (e.g., LiteLLM).
• Work closely with product and infrastructure engineers to solve real pain points, ensuring teams can adopt and scale AI effectively.
• Operationalize AI in production by implementing monitoring, evaluation, and fallback systems that keep features reliable and performant.
• Drive features from prototype through production rollout, focusing on execution and delivery.
• Keep up to date with emerging AI platform tools and frameworks, applying them where they improve team velocity and product reliability.

• Share best practices with peers and contribute to building a strong engineering culture on the team.

   

What you’ll bring

• Strong software engineering background, with 5+ years of experience building backend systems, platforms, or internal tools at scale.
• Proficiency in .NET, Java, Python, TypeScript or JavaScript.
• Experience in developer enablement, infrastructure, or platform engineering - especially with CI/CD, productivity tooling, or automation.
• Familiarity with building AI-powered applications in production, such as retrieval-augmented generation (RAG) systems, task-driven agents, or LLM-integrated tools.
• Hands-on experience with components of modern AI platforms - such as orchestration frameworks, vector databases, and monitoring/evaluation tools.
• Interest in simplifying complex AI workflows and building safe, reliable abstractions.
• Strong execution mindset - you focus on shipping reliable solutions and improving developer productivity.
• Excellent collaboration and communication skills; you thrive in cross-functional environments.
• Fluency in English.
   

OUR BENEFITS

• Annual PTO - 24 days.
• Paternity Leave: up to 14 weeks fully paid.
• Health Insurance.
