Responsibilities
Define execution lifecycles and business states, implementing strict legal transition guards
Ensure deterministic, auditable, and testable state transitions, eliminating hidden state in code
Enforce idempotency; design composite idempotency keys to prevent duplicate actions or invalid transitions
Support late events and backfills; maintain append-only history and current-state projections for efficient retrieval
Provide clear APIs for state snapshots, transitions, and feedback events
Apply the Transactional Outbox pattern, encompassing atomic persist-and-publish, idempotency keys, retry/backoff logic, and dead-letter queue management
Establish robust contracts for downstream executors and manage ingestion of delivery receipts
Guarantee exactly-once effects through idempotent consumers and deduplication strategies
Design relational schemas for transition logs, current-state projections, and outbox records, focusing on correctness and scalability
Implement composite constraints, foreign keys, upserts, and optimized indexing/partitioning for high-throughput scenarios
Define transaction boundaries and isolation levels to prevent data anomalies
Lead zero-downtime migrations using Liquibase or Flyway, utilizing forward/backward-compatible rollout strategies
Employ TypeORM or JPA/Hibernate/jOOQ pragmatically, and optimize query performance as needed
Build resilient projections and caches; leverage CDC tools (e.g., Debezium) for safe reprocessing
Architect systems for correctness amid concurrent updates, partitions, and partial failures
Apply advanced knowledge of event ordering, idempotency, retries, and backpressure management
Balance consistency and reliability with performance objectives
Instrument systems for tracing, metrics, and structured logs; develop dashboards monitoring key system indicators
Build replay tools and maintain immutable audit trails for compliance and incident response
Own runbooks and operational practices for issue resolution and system health
Partner with decision-service owners, ensuring statelessness and side-effect-free integration
Collaborate with channel teams on event schema, delivery receipt, and failure semantics
Lead design reviews and establish standards for contract-first development, migrations, and idempotent patterns
Mentor engineers on data modeling, concurrency, ORM/JPA best practices, and observability; foster a culture of rigorous testing and code review
Utilize AI tools to expedite scaffolding, testing, migration, and documentation
Ensure that core business logic and correctness remain human-authored and subject to thorough review
Maintain strict separation of concerns between decision services and state management components
Enforce idempotency across all code and schema layers
Achieve exactly-once intent through robust transport and consumer logic
Guarantee traceable audit and replay capabilities
Adhere to privacy and compliance standards, including consent management, secure logging, encryption, and role-based access
Qualification
Required
Minimum of 8 years in backend/platform service development; at least 3 years in a senior or lead role overseeing mission-critical systems

Strong expertise in relational modeling (Postgres/MySQL), query optimization, and partitioning
Skilled in TypeORM (Node.js) and/or JPA/Hibernate/jOOQ (Java/Kotlin); experienced in zero-downtime migrations
Deep understanding of transactions, isolation levels, locking, and backpressure in high-throughput environments
Experience developing contract-first APIs (OpenAPI), managing schema versioning, and ensuring backward compatibility
Preferred
Experience with stateful pipelines for notifications, fulfillment, or workflow engines
Familiarity with CDC (e.g., Debezium), CQRS, event sourcing, outbox‑poller architectures
