RT Business System Solutions Ltd (RTBSS) is a specialist consultancy and software studio based in South Wales. We help Housing Associations and Local Authorities deliver complex technical and business transformation projects — from data migration and integration to programme delivery and system configuration.
Since forming in 2021, we’ve built a strong reputation for quality, technical expertise, and pragmatic delivery. Our team continues to grow carefully and deliberately — hiring people who combine skill with curiosity and care for doing things properly.
We’re now seeking a talented Technical Consultant to join us. This is an opportunity to work at the heart of housing‑sector transformation projects — and to help design something entirely new: our own housing management software platform.

* Work directly with clients to capture, validate, and document technical and functional requirements.
* Design scalable, secure, and maintainable data and system architectures.
* Develop advanced data integration solutions using SQL Server Integration Services (SSIS) or similar ETL tools.
* Build client‑facing reports and dashboards using SSRS, Power BI, or comparable platforms.
* Guide clients through testing and deployment, ensuring smooth transitions and knowledge transfer.
* Troubleshoot complex issues during implementation or live operation.
* Provide training, mentoring, and ongoing technical support to client teams.
SQL Development and Data Engineering

* Deliver accurate, efficient data migration projects with a focus on data integrity and auditability.
* Optimise queries and indexes to improve performance and reliability.
* Develop or maintain data warehouse solutions that support analytics and reporting.
* Collaborate with in‑house developers to embed your data solutions into software systems.
* Conduct peer code reviews and enforce internal development standards.
* Keep pace with new tools, data platforms, and best practices to continually improve our approach.
Product Co‑Development (Housing Management Software)
* Collaborate with the RTBSS software development team to design database schemas and integration layers for Frontier Housing.
* Translate housing‑sector pain points into structured data models, API definitions, and workflows.

* Contribute to product documentation and help shape our long‑term data strategy.
* Extensive experience with Microsoft SQL Server and relational database technologies.
* Advanced T‑SQL proficiency, including complex query writing, stored procedures, and performance tuning.
* Proven experience delivering data migration, integration, or ETL solutions.
* Understanding of data warehousing concepts and architecture.
* Strong analytical and problem‑solving skills, with the ability to diagnose and resolve intricate technical issues.
* Clear communicator, able to explain complex ideas to both technical and non‑technical audiences.
* Experience producing clear technical documentation, data dictionaries, and system diagrams.
* Adaptable and proactive — comfortable balancing multiple projects and learning new tools quickly.
* A passion for clean design, data quality, and continuous improvement.
* Proficiency in an object‑oriented programming language (ideally C#).
* Familiarity with REST API design and consumption.
