Key Responsibilities:

• Design, build, and maintain agentic AI systems, including multi-agent orchestration frameworks (e.g. LangGraph) for digital therapy product
• Lead the migration of conversational AI bot architecture from legacy frameworks to modern agentic frameworks, improving developer velocity and feature extensibility.
• Develop and maintain fast inference service integrations to reduce end-to-end message latency and enable more responsive AI-powered interactions.
• Work closely with AI scientists and researchers to translate research prototypes into robust, production-grade software.
• Monitor AI models in production — build telemetry and observability tooling to ensure reliability and quality.
• Disseminate and instil good engineering practice, whilst able to work effectively alongside scientists who may be less focused on engineering rigour.
• Manage and mentor other engineers, supporting their technical growth and development.
• Stay current with developments in AI engineering — particularly around LLMs, agentic systems, and LLMOps — and advocate for their adoption where they can meaningfully improve our platform or engineering processes.
• Work effectively in a cross-functional team, collaborating closely with Product, QA, DevOps, Data, AI, and Engineering stakeholders
• Communicate confidently in a multinational environment with business, engineering, marketing, and clinical stakeholders when needed
• Participate fully in Agile/Scrum ceremonies and contribute to continuous improvement
• Troubleshoot complex issues, perform root-cause analysis, and investigate new tools and approaches
• Identify delivery bottlenecks, technical risks, and improvement opportunities proactively
• Help balance delivery speed, quality, scalability, maintainability, and technical debt across initiatives

Requirements:

• Agile thinker, able to work with evolving and underspecified requirements
• Proven ability to deliver software in complex, fast-moving environments.
• Strong programming skills and experience building production software systems.
• Experience with LLMs, generative AI, or modern AI engineering (including prompt engineering, LLM APIs, or agentic frameworks). 
• Enthusiasm for and comfort with the rapid changes happening in software engineering driven by AI — including AI-assisted development tools and evolving engineering practices.
• Proven ability to mentor and support others, to ‘see the bigger picture’, and make pragmatic engineering trade-offs.
• A desire to make a meaningful difference — our mission is to improve access to mental health care.
• An interest in working with data and understanding how AI systems can be safely and effectively deployed in clinical contexts.
• Solid production experience with Microsoft Azure
• Strong understanding of version control, security best practices, and Agile methodologies
• Strong Agile delivery experience with focus on speed and quality

Nice to have:

• Experience with agentic frameworks such as LangGraph, LangChain, or similar.
• Experience building or working with coding agents or AI-assisted development tooling.
• Experience deploying and operating LLMs or ML models in production (LLMOps / MLOps). 
• Experience with Azure cloud services, including Azure ML, Azure Kubernetes Service (AKS), or Azure DevOps.
• Experience with message broker systems and real-time data pipelines.
• Experience working in a regulated environment (e.g. healthcare, finance, or with HIPAA and GDPR).
• Experience delivering software in a research or clinical environment. 
• BSc or higher in Computer Science, Mathematics, or a related field.
