Senior AI Platform Engineer

Lirio is a technology/software company specializing in behavioral science and AI to enhance consumer engagement and health interventions. The Senior AI Platform Engineer will architect and maintain the software execution layer of Lirio’s Precision Nudging Platform, focusing on AI workflow design, infrastructure optimization, and ensuring compliance with healthcare regulations.

Responsibilities:

• Design and implement infrastructure to support LLM-based autonomous agents capable of multi-step reasoning, planning, and task execution
• Build and manage directed workflows using state machines and tools to coordinate complex AI-human handoffs
• Lead the architectural design and technical implementation of interoperability standards that enable seamless communication between autonomous agents and diverse software ecosystems
• Architect and maintain cloud-native platforms that support end-to-end AI workflows, from model experimentation to high-availability production deployment
• Develop evaluation frameworks and observability dashboards to monitor agent accuracy, latency, cost, and safety guardrails
• Optimize agent performance by managing tool discovery and context window efficiency through standardized protocols, ensuring agents can dynamically access and execute the right capabilities on-the-fly
• Embed healthcare regulatory compliance (e.g. HIPAA) directly into the platform layer through automated guardrails and audit trails
• Implement security controls against prompt injection and ensure PII/PHI de-identification within agentic data flows
• Implement secure authentication, role-based access controls, and data masking within interoperability layers to serve as a secure gatekeeper between AI agents and sensitive enterprise systems
• Provide subject matter expertise and technical support to engineering teams during implementation
• Build prototypes, reference integrations, or proof-of-concept solutions to validate design decisions and de-risk complex implementations
• Evaluate existing systems and propose improvements or replacements
• Promote AI-assisted engineering tools and modern development practices consistent with Lirio’s engineering culture
• Document processes, designs, implementations, and best practices for future reference
• Serve as a contributing member of Lirio’s Architecture Team, helping to maintain architectural coherence and platform quality
• Partner with Product Management to shape solution approaches before work enters development planning and execution
• Work closely with Cloud, Data, AI/ML, Behavioral Science, and Engineering teams to ensure solutions support personalization, scalability, and measurable outcomes
• Participate in the Engineering Council, helping to define and uphold engineering standards, patterns, and technical governance
• Diagnose and respond to issues in the implementation of agent orchestrations, adjusting guardrails and workflows as needed
