We are seeking a hands-on Principal Data Architect to own the target architecture for a large-scale data platform modernization at a major US mortgage lender - migrating Finance reporting off a legacy on-premises source system onto a governed cloud data platform (Azure, Microsoft Fabric, and Snowflake), with CDC-based replication and a certified BI semantic layer. This is deliberately a hands-on role: you build alongside the development team through design and build, not a review-from-a-distance seat.This position calls for a hybrid architect: someone who can design and defend complex technical decisions in front of the client's data and cloud teams at a strategic level, while also working hands-on with the development team to validate and build the solution. A strong grounding in software and data development is essential - profiles limited to analytics work alone will not have the depth this role requires.ResponsibilitiesOwn the end-to-end target architecture spanning CDC replication, lakehouse landing (Fabric/OneLake), and a layered cloud data warehouse (raw/staging -> conformed -> curated)



on Snowflake.Author and maintain architecture decision records covering transformation mechanism, CDC/load strategy, semantic-model storage mode, warehouse isolation, and cross-platform (lakehouse-to-warehouse) interoperability.Design the curated data layer and dimensional model, including recomputing source-system runtime-calculated values that don't exist in raw replicated data, and conforming key-value dimension structures into standard reporting attributes.Design the strategy for a single certified BI semantic model consumed by all downstream reporting tools, with metric definitions versioned in one governed place.Work hands-on inside the codebase alongside the development team through the design-and-build core.Lead technical discovery with client architecture, security, and platform teams; resolve open interoperability and network/identity design questions.Own quality gates for architecture decisions - design validation, baseline lock, cutover readiness - and produce the evidence client stakeholders need to sign off.Mentor the development team on transformation patterns, incremental materialization, and reconciliation/data-quality design.Requirements for this challengeSolid experience in data architecture, including hands-on delivery (not review-only) on enterprise data platform modernization programs.Proven experience architecting cloud data platforms on Snowflake,



including layered raw/staging/curated models and incremental transformation patterns (e.G., dynamic or materialized tables).Experience with Microsoft Fabric/OneLake, or a comparable lakehouse platform, including cross-platform interoperability between a lakehouse and a cloud data warehouse.Experience architecting change-data-capture (CDC) based replication pipelines (e.G., Qlik Replicate, Fivetran, Debezium, or similar) from a relational source into a cloud platform.Experience designing governed, certified BI semantic layers (Power BI or equivalent) consumed by multiple reporting tools.Strong command of data governance fundamentals: classification, masking, row-level access, lineage.Fluent English (C1) - direct engagement with client architecture, security, and executive stakeholders.Nice to HaveExperience with Microsoft Dynamics 365 Business Central or another ERP as a source system for financial/GL reporting.Experience in mortgage, lending, or broader financial-services data platforms.Familiarity with AI-assisted development toolchains inside a governed software development lifecycle (SDLC), where AI output is always a draft requiring human sign-off on production logic.Our benefits include:- Premium Healthcare- Meal voucher- Maternity and Parental leaves- Mobile services subsidy- Sick pay-Life insurance- CI&T; University- Colombian Holidays- Paid Vacations- And many others.Collaboration is our superpower, diversity unites us, and excellence is our standard.We value diverse identities and life experiences, fostering a diverse, inclusive, and safe work environment.
