Job ID: JOB_ID_5080

Job Description:

Own the target-state data architecture on Google Spanner, ensuring the new data model satisfies functional correctness, performance SLOs, and transactional semantics required by 1000+ applications before large-scale app rewrites occur. This role is not a schema converter. It is a distributed systems architect role.

Key Responsibilities:

Data Architecture & Modeling:

  • Define the Logical Canonical Data Model (LCDM) independent of physical storage.
  • Design Spanner-native physical schemas, including primary key strategy, row key distribution (hotspot avoidance), interleaving decisions, and secondary index strategy.
  • Decide where denormalization, projections, or materialized views are required.

Transaction & Consistency Design:

  • Define transaction boundaries under Spanner constraints, including single-partition vs multi-partition transactions and atomicity and consistency trade-offs.
  • Classify workloads by strong consistency vs bounded staleness tolerance.
  • Define idempotency and retry-safe patterns.

Compatibility & Contract Validation:

  • Work with QA and platform teams to validate CRUD contracts, query semantics, and transaction invariants.
  • Review and sign off on schema compatibility scorecards.

Performance & Scalability:

  • Participate in workload replay analysis.
  • Diagnose and resolve hot key risks, transaction conflicts, and index amplification.
  • Size Spanner instances and estimate cost envelopes.

Leadership:

  • Act as final authority for Spanner data design decisions.
  • Mentor domain architects and engineers.
  • Provide executive-level architectural rationale.

Required Skills & Experience:

  • 10+ years in large-scale data architecture.
  • Deep expertise in Google Spanner internals (TrueTime, distributed transactions, synchronous replication).
  • Experience designing petabyte-scale, multi-region OLTP systems.
  • Strong understanding of distributed consistency models and failure modes in globally distributed databases.
  • Prior Oracle distributed DB migration experience strongly preferred.
  • Experience in architecting High availability, High performance, Low latency workloads (Spanner, AlloyDB).

Key Deliverables:

  • Canonical logical data model.
  • Spanner physical schemas & index strategies.
  • Transaction design guidelines.
  • Performance readiness assessments.
  • Migration readiness sign-off per domain.
