It is responsible for shaping how LLM-powered agents are designed, orchestrated, tested, monitored, and improved in production. The role sits at the intersection of prompt engineering, agent architecture, solution design, and platform capability development.\nYou will define how agents interact with tools, APIs, and downstream services, and help specify the requirements and contracts for the services they depend on. You will work closely with platform engineers, who build the APIs and services consumed by agents, and with product engineers, helping ensure agent capabilities support strong user experience and front-end design.\nThis role also includes working on patterns where prompt outputs are used as code to support interface generation, front-end behaviour, and rapid product iteration. You will also own the LLM and prompt tooling lifecycle, from prompt management through evaluation, testing, and continuous improvement.\nThis is a hands-on senior role for someone who combines deep technical skill with strong systems thinking and a practical approach to building scalable, usable, and production-ready AI capabilities.\nAbout Travtus\nTravtus is transforming the Housing Industry with our Everyday (AI)™ platform. We bring intelligence and automation together in one place so teams can move faster and work smarter. By delivering everyday AI decisions and workflows across the systems operators already use daily, our platform improves efficiency while enhancing the resident experience.\nAbout the Role\nKey Responsibilities\nDesign and develop multi-agent prompts and orchestration patterns\n\nDefine how agents, tools, APIs, services, and platform components interact, including requirements, contracts, and integration patterns\n\nWork alongside platform engineers to define the APIs and services that agents consume and use\n\nWork closely with product engineers to support user experience and front-end design, including the use of prompt outputs as code\n\nOwn LLM and prompt tooling across the full lifecycle, from prompt management and versioning through evaluation, testing, and optimisation\n\nDesign requirements for downstream and supporting services that enable agent execution, workflow control, observability, and integration\n\nLead the research, evaluation, and selection of frameworks for agent orchestration, tool use, evaluation, observability, and deployment\n\nPerform model selection based on use case fit, quality, latency, scalability, and cost\n\nDesign and implement tools and function-calling patterns for agent-based systems\n\nCarry out prompt tuning and iterative optimisation of agent behaviour and output quality\n\nMonitor, debug, and continuously tune agents in development and production\n\nDesign for performance, scalability, reliability, usability, maintainability, and cost efficiency\n\nDefine and execute testing strategies for LLM agents and platform-level AI workflows\n\nIntegration test agents end to end with other parts of the platform to ensure reliability across workflows, services, and user-facing experiences\n\nBuild proofs of concept and prototypes to validate architectures, frameworks, and new platform capabilities\n\nProduce end-to-end solution designs for AI platform components and services\n\nUse AI to improve software development, including prototyping, implementation, testing, debugging, and engineering productivity\n\nCollaborate across engineering and product teams to translate business and technical goals into robust platform capabilities\n\nRequirements\nThe successful applicant will be a natural problem-solver with an affinity for automation, efficiency, and AI-driven solutions with excellent communication and collaboration skills across both technical and non-technical teams.\nMust have requirements:\nStrong experience designing, building, and deploying LLM-based applications or agentic systems\n\nDemonstrated expertise in prompt engineering, prompt tuning, and structured output design\n\nExperience designing multi-agent workflows and orchestration logic\n\nStrong understanding of API design, service integration, and interface contracts\n\nExperience owning or working with prompt management, evaluation, and testing tooling\n\nExperience working with or defining requirements for platform services that support AI applications\n\nExperience evaluating and selecting models, frameworks, and AI tooling\n\nPractical experience with tool use, function calling, workflow control, and system integration\n\nExperience defining and implementing testing and evaluation strategies for LLM systems\n\nExperience with end-to-end and integration testing across complex platform workflows\n\nStrong understanding of performance optimisation, including latency, throughput, scalability, and cost trade-offs\n\nExperience monitoring and improving AI systems in production\n\nStrong software engineering skills and experience building production-grade systems\n\nAbility to work effectively with both product engineers and platform engineers\n\nAbility to produce clear solution designs and communicate technical decisions effectively\n\nComfortable working across experimentation, architecture, and delivery\n\nNice to have requirements:\n\nExperience with agent orchestration frameworks and evaluation platforms\nFamiliarity with observability, tracing, and monitoring for AI systems\n\nExperience designing guardrails, controls, and failure handling for AI workflows\n\nExperience supporting front-end or UX-oriented engineering through AI-assisted design or generation patterns\n\nExperience with code generation or structured prompt outputs used in software delivery workflows\n\nExperience with cloud-native or distributed production environments\n\nBackground in solution architecture, or applied AI systems\n\nExperience using AI to improve internal engineering productivity and delivery\n\nWhat Success Looks Like\nThe AI platform provides a strong, scalable foundation for agent-based products and workflows\n\nAgents, tools, APIs, and service integrations are reliable, testable, and production-ready\n\nLLM and prompt tooling supports disciplined prompt management, evaluation, testing, and continuous improvement\n\nPlatform capabilities are designed with strong usability, maintainability, and operational robustness\n\nAgent outputs support high-quality product experiences, including front-end and UX use cases where appropriate\n\nModel, prompt, and framework choices are evidence-based and continuously optimised\n\nAgents are integration tested end to end with the wider platform and perform reliably across real workflows\n\nNew ideas can be rapidly validated through POCs and evolved into durable platform capabilities\n\nProduct engineers and platform engineers can work effectively around clear contracts, services, and orchestration patterns\n\nAI is used effectively both within the product and to improve software development practices\n\nAbout the Team\nWe are a dedicated team, working in a truly
