Data architect -remote

[Shaheen Syed]

Lead Data Architect - Google Spanner "Role 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. Key Responsibilities Data Architecture & Modeling • Define the Logical Canonical Data Model (LCDM) independent of physical storage. • Design Spanner-native physical schemas: o Primary key strategy 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. 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: o TrueTime o Distributed transactions o Synchronous replication • Experience designing petabyte-scale, multi-region OLTP systems • Strong understanding of: o Distributed consistency models o Failure modes in globally distributed databases • Prior Oracle → distributed DB migration experience strongly preferred Key Deliverables • Canonical logical data model • Spanner physical schemas & index strategies • Transaction design guidelines • Performance readiness assessments • Migration readiness sign-off per domain Role Descriptions: Key Responsibilities by Role TypeSoftware Engineer (Cloud Spanner Platform) Designs and implements features for distributed systems| manages database storage infrastructure| and improves performance.Site Reliability Engineer (SRE)| Spanner Focuses on system reliability| automating management processes| and managing on-call rotations to maintain uptime for large-scale production databases.Engineering Manager| Spanner Migration Leads teams to build tools for transitioning databases and drives adoption of Spanner| providing high-performance SQL capabilities.
