Why This Role Exists
We operate a multi-tenant automotive SaaS platform serving thousands of dealer groups across the United States. Our data layer — MySQL, Aurora, DynamoDB with DynamoDB Streams, S3, Glue Data Catalog — has grown to support a complex, high-throughput transactional platform. That layer works. Now we need to make it intelligent.
We are building a Dealer Intelligence Platform: a closed-loop system that observes raw signals from dealer operations, predicts outcomes, optimizes decisions under constraints, acts through approved channels, and learns from what happened. Pricing optimization, lead routing, inventory mix planning, service bay scheduling — each is a self-contained optimization function that consumes features, scores predictions, and closes the loop with action telemetry.
This role owns the entire data substrate that makes that loop possible — the lake, the feature store, the model registry, the action ledger, and the governance framework that keeps it all tenant-isolated and audit-grade. You are not inheriting a finished architecture; you are designing the one that turns a transactional platform into a decision engine.
Scope & Scale
-
Targeting 5,000+ dealer tenants, each with isolated databases and per-tenant configuration.
-
Billions in annual Gross Merchandise Value (GMV) flowing through platform transactions.
-
30+ third-party integrations across DMS, CRM, lending, F&I, and marketplace providers — each pushing data in different formats (SOAP/XML, REST, JSON, email).
-
Data pipelines spanning 6 integration domains with multi-protocol vendor connectivity.
-
Data Streams processing real-time change events across onboarding, inventory, and transaction tables.
-
A Product roadmap with 6+ optimization functions — each requiring its own entity model, feature set, constraint definition, and feedback path.
What You Will Own
-
The data platform end to end: Bronze (raw + telemetry), Silver (canonical entities via Standardization Agent), Gold (KPIs + derived features) — plus the Feature Store and Action Ledger that make the optimization loop possible.
-
Feature Store architecture — online (sub-50ms reads for real-time scoring) and offline (point-in-time joins for training). Feature contract: owner, freshness SLO, PII tag, training/inference parity. Governed by Lake Formation.
-
Action Ledger — every recommendation, approval, override, and outcome logged as a first-class object. This is the substrate that closes the loop: without it, models cannot retrain, we cannot attribute lift, and we cannot prove value to dealers.
-
Model data pipeline — the feature materialization, training data assembly, and serving infrastructure that feeds SageMaker models and Bedrock agents across all optimization functions.
-
Data migration strategy for the legacy platform — defining which tables move to DynamoDB, which consolidate into Aurora Serverless, and how dual-write validation works at every stage.
-
Data quality and anomaly detection — automated monitoring for schema drift, null-rate spikes, stale pipelines, and integration data inconsistencies. If a bad feature reaches a model, that is your bug.
-
Data governance: retention policies, PII handling, audit trail integrity, and multi-tenant AI governance (per-dealer data isolation for model training, cost attribution for Bedrock inference, FTC-grade action audit).
-
Streaming and event-driven data flows: DynamoDB Streams, EventBridge, CDC patterns, and real-time feature materialization.
Technical Environment
-
Data Stores: DynamoDB (single-table design, DynamoDB Streams), MySQL/Aurora, S3 data lake (Bronze/Silver/Gold layers, Iceberg), DAX, Glue Data Catalog.
-
Feature Store: SageMaker Feature Store (online + offline), S3 + Iceberg for point-in-time training data, Lake Formation-governed feature access.
-
Streaming & Events: DynamoDB Streams, EventBridge, CDC, real-time feature materialization pipelines.
-
ML/AI Platform: SageMaker (training pipelines, model registry, Model Monitor), AWS Bedrock (Claude, Titan), LangChain/LangGraph, Bedrock Knowledge Bases.
-
Pipelines: Apache NiFi (multi-provider normalization), AWS Glue (ETL, Data Catalog), Athena (ad-hoc analytics).
-
Infrastructure: CloudFormation, Lake Formation, OpenTelemetry, CircleCI.
-
Analytics: Glue Data Catalog, Athena, QuickSight or equivalent BI layer.
Hands-On Expectations
This is not a slides-and-meetings role. We expect roughly 30–40% of your time in code and SQL (writing critical-path feature pipelines, data migrations, schema designs, and reviewing PRs with rigor), 40–50% in design (data architecture docs, entity modeling sessions, feature catalog design, optimization-function data contracts), and 10–20% on cross-team alignment, mentoring, and operating mechanisms.
First 12 Months
-
Months 1–3: Immerse in the data landscape — audit every data store, pipeline, integration flow, and DynamoDB Stream. Map the current entity model against the v2 optimization-function requirements. Publish the first data architecture ADR. Identify the top data quality gaps and define the canonical entity schemas that Silver and Gold will standardize around.
-
Months 4–6: Stand up the Feature Store (online + offline) and migrate the first round of features from Gold derivations. Build the Action Ledger schema and approval-gateway integration. Deliver the first data migration wave with dual-write validation. Ship automated data quality monitoring that catches drift before it reaches a model.
-
Months 7–9: Pricing Optimizer data pipeline live in production — features flowing, predictions scoring, action telemetry closing the loop. Feature catalog operational with freshness SLOs and PII tagging. Per-dealer + global model training pipelines running. Lead Routing data contracts defined and in shadow mode.
-
Months 10–12: Second optimization function (Lead Routing or Inventory Mix) in production. Drift detection and auto-rollback wired into Model Monitor. Outcome dashboards proving incremental lift to dealers. Data platform roadmap documented for the next 12 months. The team treats feature quality, action telemetry, and training/inference parity as non-negotiable engineering standards because of the patterns you set.
Requirements
You Should Have
-
7+ years in data engineering or data architecture with at least 2 years in a platform-level architect or Head-of role.
-
Deep experience with both relational (MySQL/PostgreSQL/Aurora) and NoSQL (DynamoDB, DynamoDB Streams) data modeling — and strong opinions on when each is appropriate.
-
Hands-on experience building or operating feature stores — online serving, offline training, point-in-time correctness, feature freshness SLOs.
-
Hands-on experience with AWS data and ML services: Glue, Athena, S3, DynamoDB, DynamoDB Streams, Aurora, Lake Formation, SageMaker.
-
Current, practicing AI/Gen-AI practitioner — you have built or operated systems that prepare data for LLMs, embeddings, or ML models in production. This is not theoretical interest; it is hands-on recent experience.
-
Experience with streaming and CDC patterns: DynamoDB Streams, Kinesis, EventBridge, or Kafka for real-time data propagation and feature materialization.
-
Experience with data pipeline orchestration: NiFi, Airflow, Step Functions, or equivalent.
-
Understanding of data migration patterns: dual-write, change data capture (CDC), reconciliation validation, zero-downtime cutover.
-
Experience with multi-tenant data architectures — database-per-tenant, schema-per-tenant, Row-Level Security, and the judgment to know which trade-offs matter at 5,000+ tenants.
-
Strong data governance instincts: retention policies, PII handling, audit trails, cost attribution, and the discipline to enforce them before the first model ships.
-
The ability to write a data architecture doc that engineers can implement without ambiguity, and the judgment to know when to write the SQL or pipeline code yourself instead.
Strongly Preferred: ML & Optimization Data Infrastructure
-
Hands-on experience with SageMaker — training pipelines, model registry, Model Monitor, and production model lifecycle (shadow canary drift watch auto-rollback).
-
Hands-on experience with AWS Bedrock — Knowledge Bases, model invocation, guardrails, and production deployment of foundation models.
