Oracle Data Migration Architect, Oracle Fusion Cloud and PeopleSoft

Oracle Data Migration Architect, Oracle Fusion Cloud and People Soft

Working alongside Tessera Labs' Mosaic AI Agents

Location: US East Coast

Remote: Yes

Engagement type: Full-time employee or fixed-term contract (initial 3 to 6 months), full-time capacity, with possibility of extension

Start date: Immediate (November)

Engagement model: Senior on-site role. Leads the Oracle data conversion for a large US financial services client moving from People Soft and other legacy finance systems to Oracle Fusion Cloud. Works with Tessera Labs' Forward Deployed Engineers, offshore Oracle data conversion consultants and Mosaic AI agents, and is the primary Oracle voice with the client's finance team and its systems integrator.

Tessera Labs is redefining how enterprises adopt and operationalize Artificial Intelligence. Backed by Foundation Capital and led by a world-class founding team, we combine deep enterprise ERP expertise with autonomous AI agents to deliver transformation outcomes at a fraction of the traditional time and cost.

Our mission is to bring real AI automation to the enterprise, delivering speed, precision, and measurable impact. We operate with extreme ownership, move fast, and hold ourselves to the same rigor as the best traditional system integrators while working at AI-native speed.

We are seeking a hands-on Oracle Data Migration Architect to own the architecture and end-to-end execution of a multi-release finance data conversion from People Soft and other legacy systems into Oracle Fusion Cloud. This person is the functional and data authority for the conversion: they speak the language of Oracle Fusion Financials, Procurement and Projects, and they understand People Soft source data well enough to explain what every legacy value becomes in Fusion.

This is not a configuration role. Oracle configuration is owned by the client's systems integrator. This role owns the data: mapping, business rules, FBDI load files, mock conversion cycles and reconciliation, with Tessera's platform and AI agents doing the extraction, transformation and loading at scale.

• Own the conversion blueprint across releases: objects in scope, dependencies, load sequence and mock cycle plan, aligned to the client's entry and exit criteria.
• Lead source-to-target mapping from People Soft and other sources (for example Coda, Advantage, Basware, Clarity, Workday) to Oracle Fusion, including chart of accounts crosswalks and EDMCS hierarchies.
• Define business rules, value mappings and data quality rules, and review the mappings and rules drafted by Mosaic AI agents before they are used.
• Decide cutover treatment for open items and in-flight transactions, and the approach for interim-state and reverse mapping where needed.

• Own FBDI and HDL template usage per object, and work with the systems integrator on load sequencing, environments and load error resolution.
• Run mock conversion cycles end to end and diagnose load failures in Oracle Fusion terms.
• Set reconciliation controls (counts, balances, aging, subledger to GL) and drive reconciliation to the client's exit criteria, including 100% reconciliation for Fixed Assets and Projects.
• Secure business validation and sign-off for each release.

• Act as the senior Oracle point of contact on site with the client's finance SMEs, data conversion lead and systems integrator.
• Lead mapping reviews, exception decisions and sign-off sessions, and explain differences in accounting language.
• Flag scope, risk and readiness issues early, including source system access, environment readiness and SME availability.

• Guide offshore Oracle data conversion consultants and Forward Deployed Engineers on functional data questions.
• Act as the final quality gate for AI-generated mappings, transformations and load files before they reach the client.

• 10+ years in Oracle ERP, with at least 3 end-to-end Oracle Fusion Cloud data conversions or migrations.
• Strong functional understanding of Oracle Fusion Financials (GL, AP, AR, Fixed Assets) and working knowledge of Procurement and Projects (PPM).
• Hands-on experience with People Soft Financials data structures as a conversion source.
• Deep experience with FBDI (and HDL where relevant), load error resolution and mock conversion cycles.
• Proven financial reconciliation experience,…
