About this role.
Zone & Co is seeking a senior Platform Product Engineer to build scalable platform infrastructure and customer-facing AI capabilities for its NetSuite-focused financial operations SaaS product. The role combines backend and cloud engineering with AI product development, including agentic workflows, automated validation, and integration of AI/ML models into production systems. The engineer will use Python, JavaScript/TypeScript, AWS services, relational and non-relational databases, and modern AI-assisted development tools. This is a high-autonomy remote role requiring strong architectural judgment, proactive technical-debt management, and mentorship of less-experienced engineers. The position is especially suited to an experienced fintech or ERP/SaaS engineer comfortable converting ambiguous requirements into reliable production solutions.

Sample interview questions
I would start by defining bounded actions, authoritative data sources, approval rules, and clear success criteria. The workflow would use structured tool calls, role-based access, idempotency controls, audit logs, and human approval for high-impact actions. I would also implement automated evaluation cases and production monitoring to detect incorrect outputs, drift, and unexpected tool behavior.
I would combine deterministic rules with model-based evaluation rather than relying on a model alone. This includes schema validation, reconciliation against source-of-truth ERP data, business-rule tests, confidence thresholds, exception queues, and regression suites built from representative historical cases. Every decision should be traceable, reproducible where possible, and observable in production.
I would clarify the user problem, affected workflows, risks, data availability, and measurable outcome before proposing architecture. I would then divide delivery into thin vertical slices, beginning with a low-risk prototype and instrumentation, followed by controlled production integration and broader automation. This approach makes dependencies and tradeoffs visible early while creating opportunities for stakeholder feedback.
I would choose services according to workload characteristics: ECS or Lambda for compute, Postgres for transactional data, DynamoDB for low-latency key-value access, S3 for durable object storage, and Bedrock for managed foundation-model capabilities. I would provision these through infrastructure as code, apply least-privilege IAM, use observability for latency and failures, and control cost through scaling policies, lifecycle rules, and workload monitoring.
I translate the issue into business impact, such as delivery risk, reliability exposure, customer impact, compliance risk, or rising operational cost. I present practical options with estimated effort, benefits, risks, and a recommended path, avoiding unnecessary implementation detail. This allows stakeholders to make informed prioritization decisions while preserving engineering accountability.
