Job Summary
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.
Define the Logical Canonical Data Model (LCDM) independent of physical storage.
Design Spanner-native physical schemas:
o Row key distribution (hotspot avoidance)
o Interleaving decisions
o Secondary index strategy
Decide where denormalization projections or materialized views are required.
Transaction & Consistency Design
Define transaction boundaries under Spanner constraints:
o Single-partition vs multi-partition transactions
o 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:
o CRUD contracts
o Query semantics
o Transaction invariants
Review and sign off on schema compatibility scorecards.
Performance & Scalability
Participate in workload replay analysis.
Diagnose and resolve:
o Hot key risks
o Transaction conflicts
o Index amplification
Size Spanner instances and estimate cost envelopes.
Required Skills:
10 years in large-scale data architecture
Deep expertise in Google Spanner internals:
o TrueTime
o Distributed transactions
o Synchronous replication
Experience designing petabyte-scale multi-region OLTP systems
o Distributed consistency models
o Failure modes in globally distributed databases
Prior Oracle distributed DB migration experience strongly preferred
