This role is focused on platform development. 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. You 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. This 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. This 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. About Travtus Travtus 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. About the Role Key Responsibilities • Design and develop multi-agent prompts and orchestration patterns • Define how agents, tools, APIs, services, and platform components interact, including requirements, contracts, and integration patterns • Work alongside platform engineers to define the APIs and services that agents consume and use • Work closely with product engineers to support user experience and front-end design, including the use of prompt outputs as code • Own LLM and prompt tooling across the full lifecycle, from prompt management and versioning through evaluation, testing, and optimisation • Design requirements for downstream and supporting services that enable agent execution, workflow control, observability, and integration • Lead the research, evaluation, and selection of frameworks for agent orchestration, tool use, evaluation, observability, and deployment • Perform model selection based on use case fit, quality, latency, scalability, and cost • Design and implement tools and function-calling patterns for agent-based systems • Carry out prompt tuning and iterative optimisation of agent behaviour and output quality • Monitor, debug, and continuously tune agents in development and production • Design for performance, scalability, reliability, usability, maintainability, and cost efficiency • Define and execute testing strategies for LLM agents and platform-level AI workflows • Integration test agents end to end with other parts of the platform to ensure reliability across workflows, services, and user-facing experiences • Build proofs of concept and prototypes to validate architectures, frameworks, and new platform capabilities • Produce end-to-end solution designs for AI platform components and services • Use AI to improve software development , including prototyping, implementation, testing, debugging, and engineering productivity • Collaborate across engineering and product teams to translate business and technical goals into robust platform capabilities Requirements The 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. Must have requirements: • Strong experience designing, building, and deploying LLM-based applications or agentic systems • Demonstrated expertise in prompt engineering , prompt tuning, and structured output design • Experience designing multi-agent workflows and orchestration logic • Strong understanding of API design , service integration, and interface contracts • Experience owning or working with prompt management, evaluation, and testing tooling • Experience working with or defining requirements for platform services that support AI applications • Experience evaluating and selecting models, frameworks, and AI tooling • Practical experience with tool use, function calling, workflow control, and system integration • Experience defining and implementing testing and evaluation strategies for LLM systems • Experience with end-to-end and integration testing across complex platform workflows • Strong understanding of performance optimisation , including latency, throughput, scalability, and cost trade-offs • Experience monitoring and improving AI systems in production • Strong software engineering skills and experience building production-grade systems • Ability to work effectively with both product engineers and platform engineers • Ability to produce clear solution designs and communicate technical decisions effectively • Comfortable working across experimentation, architecture, and delivery Nice to have requirements: Experience with agent orchestration frameworks and evaluation platforms • Familiarity with observability, tracing, and monitoring for AI systems • Experience designing guardrails, controls, and failure handling for AI workflows • Experience supporting front-end or UX-oriented engineering through AI-assisted design or generation patterns • Experience with code generation or structured prompt outputs used in software delivery workflows • Experience with clou Description from travtus' public careers feed, reproduced so you can read the role here.
