• Senior Data Engineer - NEC System • Portsmouth - Onsite 1 day a week • 6 month contract - 2 year programme • Inside of IR35 • £600 per day My client is embarking on a major transformation of its Housing Management services — replacing several ageing, disparate systems with a single, modern, cloud‑hosted Housing Management System (HMS). This high‑impact, strategically backed programme will improve services for more than 15,000 households and establish a strong digital foundation for future change.

As the Data Lead, you will: • Lead migration from NEC Housing to the new HMS • Own the ETL lifecycle — export, transform, cleanse, deduplicate, validate, and load. • Analyse existing data structures, working with housing teams to interpret free‑text or non‑standard data and determine what should move into the target system. Key Skills and Experience • Strong experience as a hands on Senior Data Engineer • Experience working with local authority or housing associations, including regulatory requirements, compliance and consumer standards. • Proven track record migrating data from systems such as NEC Housing or other major HMS platforms. • Expertise in ETL processes, data modelling, cleansing, SQL‑based transformation and multi‑stage reconciliation cycles. • Understanding of cloud‑hosted SaaS architectures, APIs and secure integration patterns.
