About the role

  • Our backend - event-driven serverless on AWS (Lambda, EventBridge, DynamoDB, S3, Step Functions) - orchestrates everything from dealer onboarding to inventory management to real-time transaction processing.
  • You are not advising on AI strategy from a whiteboard.

Responsibilities

  • observability (OpenTelemetry, CloudWatch), security posture (Auth0 consolidation, IAM), and data architecture (DynamoDB single-table design, Aurora consolidation).
  • Mentoring and force-multiplying senior ICs - establishing patterns, reviewing designs, and raising the technical bar across 5 engineering teams.
  • Complex data architectures featuring DynamoDB single-table design, MySQL/Aurora, S3 data lakes, Glue Data Catalog, Athena, and Data pipelines.
  • We measure our success by the dealer's wins and the trust of their buyers, not just our own code.

Requirements

  • You Should Have 8+ years of software engineering experience with at least 3 years in a Staff / Principal / Architect role.
  • Experience spending 10-20% of your time in mentoring, cross-team alignment and operating mechanisms.
  • Track record of leading monolith-to-services migrations - strangler fig, dual-write validation, traffic-splitting, canary rollouts.

Nice to have

  • Automotive, fintech, or multi-tenant marketplace platform experience.
  • Experience with data pipelines (NiFi, Glue/Athena) or ETL/data lake tooling.
  • Familiarity with Auth0 Organization model, M2M apps, and Actions for JWT enrichment.
  • Experience with browser automation (Playwright) in production integration flows.
  • Relentless Ownership: No lone wolves, but no pass-backs either.
  • We don't say "that's not my job." Invent with Purpose: We don't chase "shiny" tech.
  • We check egos at the door.
  • Evolve or Evaporate: Change is our constant.

Skills

  • These are not chatbots bolted onto a dashboard.
  • Scope & Scale 5000+ destination dealer tenants, each with isolated databases and per-tenant configuration.
  • Billions in annual Gross Merchandise Value (GMV) flowing through platform transactions.
  • Tens of thousands of API requests per minute across REST, SOAP, and event-driven integration surfaces.
  • Data pipelines spanning 6 integration domains with multi-protocol vendor connectivity.
  • High-availability AWS stack including Lambda, EventBridge, DynamoDB, S3, ECS Fargate, Aurora, API Gateway, CloudWatch, and Secrets Manager.
  • Advanced agentic workflow orchestration utilizing lean AWS Bedrock AgentCore, MCP servers, or LangChain/LangGraph frameworks.

Compensation

  • The expected salary range for this role is $195,000 to $220,000 annually, commensurate with experience and qualifications.

Benefits

  • A2Z Sync offers comprehensive medical, dental, and vision benefits.
  • Employer provided STD/LTD and life insurance.
  • Unlimited paid time off, including 10 paid holidays.

Company info

  • how agents connect to production systems, how we evaluate output quality, how we manage model costs at scale, and how we roll back when an agent misbehaves.
  • System design and technical decision-making for migration waves - from identity/tenant services through core domain extraction and frontend decomposition.
  • The dual-write framework, API Gateway traffic-splitting, and per-tenant feature flag rollout that make every migration step reversible.
  • We are Better Together.
