Job title: SAP BW/4HANA Technical Architect – Conversion / Brownfield
Work Location: Juno Beach, FL – Hybrid
Minimum years of experience: 15+ Years
Key Responsibilities
Architecture & Design
- Own and sign off the target BW/4HANA data architecture, including ADSO and CompositeProvider design, LSA++ layer strategy, HANA pushdown approach, and data tiering (hot / warm / cold).
- Define the conversion approach (Remote Conversion — Brown Field) and govern its execution across Sandbox, Development, QA and Production environments.
- Lead the object-classification exercise for all 9,162 BW objects, confirming each as convertible, adjustment-required or nonconvertible, and define the remediation path.
- Govern scope rationalisation: drive the reduction of ~1,512 BEx queries to the agreed ~338–350 target, retiring ADHOC (Y*) content and year-based structures with business justification.
- Approve architecture design documents, data model blueprints, integration architecture and security framework before development begins.
- Conversion & Remediation
- Direct the multi-step Sandbox → Development → QA → Production remote conversion sequence, including SUM execution, BW/4HANA Starter Add-on and RFC connectivity setup.
- Provide hands-on technical leadership for remediation of the 3,113 nonconvertible + 1,112 adjustment-required objects, including unsupported transformations, InfoPackages, APD-based processes and custom ABAP.
- Review and approve all AMDP / SQLScript rewrites and HANA pushdown implementations by the offshore team.
- Ensure reporting-layer readiness: BEx query conversion and rework, AFO workbook re-pointing, Power BI and BusinessObjects re-connection, and security role migration (~30–35 roles).
- Oversee compatibility of all inbound integrations (SAP S/4HANA, SuccessFactors, ServiceNow, Fieldglass, flat files) and outbound feeds (Finance BW, Open Hub destinations) in the parallel BW/4HANA environment before cutover.
- Custom Objects & Integrations
- Lead the technical approach for custom Z/Y tables, custom ABAP programs, SAP CPI iFlows and web services — classifying each as retain / re-point / redesign / retire.
- Ensure code-inspector and ATC scans are executed and all HANA-incompatible statements remediated before system conversion.
- Sign off on SPAU/SPDD completion in Development, and validate that break-fix transport retrofits into BW/4HANA DEV remain aligned with the parallel legacy landscape.
Testing, Cutover & Go-Live
- Drive the overall testing strategy: Unit Testing, SIT, Performance Benchmarking, Full Mock Migration, Dress Rehearsal and UAT.
- Oversee multi-level automated data reconciliation (record count, aggregates, key figures) at every mock cycle and at production cutover, using the Report Validator accelerator.
- Define and execute the Soft Freeze and Hard Freeze governance framework in the lead-up to production cutover.
- Lead the production cutover and manage the ~30-hour cutover window across Basis, BW, Infrastructure and Business teams; serve as the on-site decision-maker for go / no-go and rollback.
- Provide Hypercare support during the mandatory 4-week post-go-live period, monitoring process chains, integrations and data loads.
- Client Engagement & Governance
- Act as the primary Infosys technical interface with BW Lead, Basis Team Lead, Security and Infrastructure teams on a daily basis.
- Represent Infosys in Weekly Project Status Reviews and contribute architectural input to monthly Steering Committee and Executive Governance Reviews.
- Maintain the RAID log for all technical risks, assumptions, issues and dependencies; escalate architectural blockers within 24 hours per the programme's escalation SLAs.
- Manage the Change Request process for technical scope changes, completing impact assessment across schedule, cost and risk before approval.
- Conduct knowledge transfer sessions and produce technical specification documentation for newly developed models, ensuring support team can sustain the BW/4HANA landscape post-programme.
