Principal/Staff Engineer (Data)

• 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

• Extensive experience overseeing data architecture and a track record of delivering iterative outcomes across one or more OLAP domains
• Strong understanding of data modelling techniques (Star, Medallion, etc) and distributed data systems within cloud-native environments (Snowflake, etc).
• Experience in building and leveraging unstructured data across disparate systems to enable product development.
• Examples of communication and influencing across technical and non-technical audiences to achieve positive outcomes.
• An ability to support the growth of engineers and technical leads whilst still delivering value across distributed, cross-functional teams.
• Demonstrable experience working in an ownership culture where quality, performance, observability, and security are core responsibilities for every engineer
• An understanding and opinion on how AI-first engineering will change the data ecosystem and ways of working, ideally with worked examples
• Examples of contributing to or leading technical communities of practice (e.g. chapters, guilds, architecture councils).
• Practical knowledge of DataOps principles, including CI/CD for data and the orchestration of complex pipelines (e.g., AWS, Debezium, Git, Infra as Code).
• Good commercial knowledge of data security standards, encryption at rest/transit, and relevant compliance laws.
• Platform financial acumen - demonstrable experience of optimising SaaS platform spend, and the use of forecasting models.

• AI/ML Engineering & MLOps, including model deployment/serving and monitoring.
• Experience with federated learning and/or privacy-enhancing technologies (PETs).
• Direct experience with LLM Ops, including prompt engineering at scale, and token cost optimisation.
