Job Description:

ROLE OVERVIEW:

Client is building the next generation of its Customer Data Platform (CDP) a massive scale Audience Builder and Campaign Management platform serving over 400 million customer profiles.
Were looking for a Senior Backend Engineer who loves hard problems distributed systems at scale real-time data pipelines and the infrastructure that powers one of the most ambitious marketing technology platforms in the industry.
This role sits at the intersection of CDP engineering data platform architecture and marketing technology.
You will design build and own the services APIs and platform capabilities that underpin client ability to understand segment and activate its customer base across every channel in near real-time.

WHY THIS ROLE MATTERS:

Customer Data Platforms are the backbone of modern personalized marketing. At client scale 400M profiles petabytes of behavioral and transactional data dozens of activation channels building the CDP backend is a genuine engineering challenge.
Youll work on.
Identity resolution and profile unification across fragmented customer touchpoints
Sub-second audience segmentation across hundreds of millions of profiles
Event-driven data pipelines that keep customer profiles fresh in near real-time
Multi-channel activation from Kafka topics to S3 exports to partner APIs
The observability reliability and security infrastructure that makes all of it trustworthy at scale

KEY RESPONSIBILITIES:

CDP Customer Profile Platform
Design and operate the unified customer profile layer the core of client CDP supporting 400M profiles with high-throughput ingestion identity resolution and real time enrichment.
Architect and build scalable customer profile services supporting 400M profiles with sub-second access patterns
Implement identity resolution and profile stitching across first-party and third party data sources a critical CDP capability
Support high-volume batch ingestion incremental processing and near real time profile updates driven by behavioral events
Evaluate and implement storage technologies including Cassandra DynamoDB ScyllaDB MongoDB and PostgreSQL for distinct workload profiles
Build attribute enrichment pipelines that continuously improve profile completeness and accuracy
Implement data governance controls including consent management data suppression and regulatory compliance hooks (CCPA TCPA)
Real Time Data Ingestion & Event Processing
Build the event driven infrastructure that keeps customer profiles synchronized with whats happening right now the heartbeat of a modern CDP.
Design and build event-driven architectures using Kafka and event streaming platforms for real time profile updates
Implement change data capture (CDC) pipelines to propagate updates from source systems into the CDP profile store
Build data synchronization services supporting multi source fan-in and downstream fan out to activation channels
Implement dead-letter queues retry strategies and failure recovery for mission-critical data pipelines
Ensure event ordering guarantees and exactly once processing semantics where required
Audience Segmentation Engine
Build the high-performance segmentation engine that enables marketers to define and generate audiences of any complexity at scale.
Design and build an audience generation service capable of evaluating complex nested filter logic across 400M profiles
Support attribute-based filtering hierarchical attribute traversal AND/OR conditional logic inclusion and exclusion criteria
Implement dynamic audience generation with real-time estimation to support pre-activation reach planning
Optimize query execution using columnar storage pre-aggregation and intelligent caching strategies
Build audience snapshot and version management to support reproducibility and campaign history
Integrate with the CDP profile store to ensure segmentation reflects the most current available profile state
Campaign Management & Lifecycle Services
Build the durable consistent services that manage campaign definitions from creation through execution.
Develop APIs for campaign creation versioning configuration approval scheduling and lifecycle transitions
Persist campaign definitions segmentation rules targeting criteria and execution metadata with full audit support
Implement campaign versioning and change tracking to support rollback comparison and governance requirements
Build approval workflow services supporting configurable multi-stage review before campaign activation
Analytics & Audience Insights
Build the analytical layer that gives users visibility into audience composition campaign reach and performance - a defining capability of enterprise CDPs.
Build services providing real-time audience size estimation reachability calculations and channel eligibility analysis
Implement segment distribution analytics demographic breakdowns attribute frequency distributions overlap analysis
Support both real-time query serving and scheduled batch analytical workloads
Build historical campaign reporting infrastructure for performance analysis and optimization feedback loops
Expose analytical APIs that the UI layer can leverage for interactive exploration
Activation & Multi-Channel Delivery
Implement the delivery layer that gets audience segments into activation channels reliably and at scale.
Build file-based delivery to Amazon S3 Azure Blob Storage and Google Cloud Storage for downstream consumption
Implement API-based delivery to internal and external partner systems via REST and event-based integrations
Build event-based delivery using Kafka topics Event Hubs and Pub/Sub systems
Implement delivery monitoring configurable retry policies and failure recovery with full observability
Support delivery SLAs with alerting and automated escalation for time-sensitive campaign activations
Campaign Execution Orchestration
Build the orchestration layer that reliably executes campaign activations on schedule and at scale.
Design and build an orchestration service supporting one-time recurring and scheduled campaign activations
Implement distributed scheduling with fault tolerance retry and idempotent execution guarantees
Build execution monitoring with real-time status tracking alerting and SLA enforcement
Support parallel execution across large audience segments with configurable concurrency and rate limiting
Security Multi Tenancy & Governance
Implement Role-Based Access Control (RBAC) with fine-grained permissions at workspace campaign and data levels
Build multi-workspace architecture with strict data isolation and cross-workspace access controls
Implement audit logging for all data access mutation events and system actions
Integrate data governance controls supporting consent flags data suppression lists and regulatory requirements
Build security monitoring and anomaly detection for sensitive customer data access patterns
Platform Reliability & Observability
Build observability solutions including metrics structured logging distributed tracing and alerting
Define and instrument SLIs SLOs and SLAs across all platform services
Implement capacity planning tooling and auto-scaling patterns for traffic variability
Conduct regular chaos engineering and failure mode analysis to improve platform resilience
