Engagement Overview
This Data Architect role is focused on stabilizing, documenting, and enabling BAU operation of critical data engineering pipelines.
The Architect will operate in a delivery-led, time-bound engagement, supporting Phase 1 and Phase 2 pipeline operations by producing clear architectural artefacts, data flow analysis, and operationally usable documentation that reduce risk, enable service continuity, and support handover into managed BAU support.
The role is hands-on and outcomes-driven, requiring the contractor to be productive from day one, work with partially documented systems, and extract critical knowledge from data engineering SMEs.
Objectives for the Role
The Data Architect will be accountable for:
* Rapidly understanding how critical data pipelines work today
* Making implicit and tribal knowledge explicit
Producing architecture and data flow artefacts that are:
* Operable
* Supportable
* Transferable into BAU
* Enabling service readiness rather than defining long-term future-state platforms
This role does not own platform modernization and must operate within clearly defined project boundaries.
Key Deliverables & Responsibilities
1. Critical Pipeline Architecture Support
* Analyze and document existing critical data engineering pipelines.
Contribute directly to:
* Critical Pipeline Inventory
* Service criticality and operational risk assessments
Identify:
* Architectural dependencies
* Single points of failure
* Knowledge concentration risks
* Ensure architectural documentation aligns with operational continuity needs, not just design intent.
2. Data Flow & Source System Analysis
* Produce end-to-end data flow mappings for critical pipelines, covering:
* Source systems and data collection mechanisms
* Processing stages and centralized transformations
* Intermediate storage and handoffs
* Downstream consumers and dependencies
Document:
* Submission triggers (scheduled, event-driven, manual)
* Data volumes, cadence, and SLA sensitivities
* Source system availability and dependency risks
* Explain and contextualize the current heavy central processing model, identifying:
* Statutory or regulatory drivers
* Legacy or convenience-driven complexity
3. Business Logic & Architectural Knowledge Capture
* Capture and structure business rules, transformations, validations, and aggregations per critical pipeline.
* Clearly distinguish:
* Regulatory/statutory logic
* Operationally required logic
* Legacy technical debt
Populate and maintain a Business Logic Repository suitable for:
* Incident resolution
* Knowledge transfer
* Ongoing BAU support
4. BAU Service Model Enablement
* Ensure architectural outputs support the defined BAU service model, including:
* Operational playbooks
* Incident response procedures
* Escalation and dependency clarity
Provide architectural input into:
* SLA/OLA alignment
* Change management and release controls
* Disaster recovery (DR) robustness assessments
* Validate architectural readiness for handover into managed operations.
5. Knowledge Transfer & Handover Support
* Actively support knowledge transfer activities with:
* Data pipeline SMEs
* Operational and support teams
Ensure all architectural artefacts are:
* Clear
* Complete
* Validated with SMEs
* Support shadow and supervised operation periods as required.
* Enable formal handover and sign-off for BAU readiness.
6. Pipeline Improvement Identification (Architectural Input)
* Identify pipeline-level improvement opportunities with an operations-first mindset.
Assess recommendations against:
* Immediate operational benefit
* Risk reduction
* Alignment with platform modernization boundaries
Support classification of improvements as:
* Tactical ( Do Now )
* Strategic ( Defer to Platform Modernization )
* Ensure no recommendations create rework or conflict with future platform changes.
Essential Experience
* Proven experience as a Data Architect on complex, Legacy data estates.
Strong background working with:
* Data engineering pipelines
* Batch/scheduled processing
* Centralized data processing models
Demonstrated ability to:
* Rapidly understand undocumented or poorly documented systems
* Produce operationally usable architecture and data flow artefacts
* Experience supporting BAU operations, service transition, or operational handover.
* Comfortable working under time-boxed delivery constraints with minimal onboarding.
Desirable Experience
* Experience within Healthcare, public sector, or other highly regulated data environments.
Familiarity with:
* SLA/OLA-driven service models
* Incident, problem, and change management processes
* Previous involvement in knowledge transfer or service transition engagements.
* Ability to work effectively alongside service management and operational teams.
Working Approach (Contractor Expectations)
* Delivery-focused and self-directed
* Low dependency on management direction
* Pragmatic rather than theoretical
* Comfortable engaging with technical SMEs and senior stakeholders
* Produces documentation that is usable in live operations, not just design reviews
