Work Location:

Juno Beach, FL – Hybrid

Minimum years of experience: 15+ Years

• Own and sign off the target BW/4
  
  HANA data architecture, including ADSO and Composite Provider 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.

• Direct the multi-step Sandbox → Development → QA → Production remote conversion sequence, including SUM execution, BW/4
  
  HANA 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, Info Packages, 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 Business Objects re-connection, and security role migration (~30–35 roles).
• Oversee compatibility of all inbound integrations (SAP S/4
  
  HANA, Success Factors, Service Now, Fieldglass, flat files) and outbound feeds (Finance BW, Open Hub destinations) in the parallel BW/4
  
  HANA environment before cutover.

• 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/4
  
  HANA DEV remain aligned with the parallel legacy landscape.

• 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.

• 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; elevate 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/4
  
  HANA landscape post-programme.
