The Technical Consultant is responsible for designing, building, and supporting the technical solutions that underpin BAC's consulting engagements.
This role serves as the technical backbone of the delivery team, translating business requirements into robust, scalable implementations across CRM platforms, integration middleware, and client systems.
This role spans three interconnected technical domains:
CRM & Platform Development: Custom development within HubSpot and other CRM platforms, including coded actions, workflow extensions, API integrations, and UI customisations
Integration Engineering: Architecture and implementation of data flows between HubSpot, client systems (ERPs, LOSs, marketing automation tools), and middleware platforms such as N8N and Make
Technical Solution Design: End-to-end systems architecture, solution scoping, and technical advisory to ensure implementations are scalable, maintainable, and aligned with client business objectives
Beyond functional delivery, this role is accountable for establishing and maintaining technical standards, documentation practices, and reusable solution patterns that enable BAC to scale its delivery capability while maintaining quality and consistency.
This is a delivery-focused technical role.
It is not a revenue-carrying position, but directly contributes to project profitability through efficient, high-quality technical execution and the reduction of rework and scope creep through sound technical design.
