• Define and evangelise target architectures that bridge our transactional, analytical, and AI systems, ensuring our data remains a competitive advantage. • Be a leader for our end-to-end data lifecycle, from OLTP schema design and migrations to OLAP governance, platform and analytics. • Partner with Technical Leads to provide hands-on guidance supporting feature delivery, tech debt paydown, and architecture improvements. (Hands-on for this role means staying close to the details but not necessarily coding) • Collaborate with Product Directors to understand product vision and translate this into deliverables, aligning commercial and engineering goals. • Lead our shift to an AI-First way of working, architecting the data foundations to enable AI in our products and championing the latest approaches to help drive productivity gains • Architect the future infrastructure required for LLM orchestration, Retrieval-Augmented Generation (RAG), and real-time model inference at scale • Mentor and coach Technical Leads/Senior Engineers on architectural and engineering excellence, continually raising our bar and supporting career growth • Act as a role model for technical leadership — work with pace, be pragmatic, and stay laser focused on outcomes not output • Head up architectural reviews for your domain and ensure all designs meet Arbor’s quality, reliability, security and compliance standards. • Collaborate with Staff Engineers and Principal Engineers to shape Arbor’s broader technology strategy, working outside your domain as needed • Partner with Engineering Management to help grow teams, identify and resolve systemic bottlenecks, ensuring the success of our strategic goals

• Own and deliver clear target architectures, strategies and roadmaps to support our product suite and strategic direction. • Partner with Technical Leads to provide hands-on guidance supporting feature delivery, tech debt paydown, and architecture improvements. (Hands-on for this role means staying close to the details but not necessarily coding) • Collaborate with Product Directors to understand product vision and translate this into deliverables, aligning commercial and engineering goals. • Lead our shift to an AI-First way of working, architecting new SDLC foundations and championing the latest approaches to help drive productivity gains across all teams • Mentor and coach Technical Leads/Senior Engineers on architectural and engineering excellence, continually raising our bar and supporting career growth • Act as a role model for technical leadership — work with pace, be pragmatic, and stay laser focused on outcomes not output • Head up architectural reviews for your domain and ensure all designs meet Arbor’s quality, reliability, security and compliance standards. • Collaborate with Staff Engineers and Principal Engineers to shape Arbor’s broader technology strategy, working outside your domain as needed • Partner with Engineering Management to help grow teams, identify dependencies/risks, and report progress against strategic goals

• Lead payments projects end-to-end: discovery with Product and PayOps teams, integration design with PSPs, build, rollout, monitoring, and incident response. • Partner with the Product team to gain insight into organizer and traveler challenges, building payment solutions that successfully process transactions. • Own the reliability of our payments system • Contribute to WeTravel’s engineering practices and excellence.

• Build end-to-end product features across frontend, backend, and AI integrations • Design agent workflows that handle planning, tool use, failure, and recovery across multiple steps. • Integrate LLMs, memory, and external tools into systems that behave reliably under real-world conditions • Design real-time AI interactions with streaming, partial results, and tight latency constraints • Improve system reliability, observability, and fallback mechanisms • Collaborate closely with ML, backend, and product teams to ship features end-to-end • Continuously iterate based on real usage and failure modes
