About this role.
This remote Senior Back-end Engineer role owns a pet-tech platform’s backend, spanning public API schemas, PHP/Laravel services, Python systems, and AWS infrastructure. The engineer will build and evolve production features, integrate AI-powered capabilities, and establish effective AI coding-agent workflows across a large codebase. Key technical areas include event-driven architectures, Amazon SQS, ECS, Lambda, Terraform, MySQL, Redis, and production observability. The position partners with cross-functional teams and requires strong architectural judgment, operational ownership, and the ability to deliver independently in a remote environment.

Sample interview questions
I would have the API validate and persist the request state, then publish an idempotent message containing a correlation ID to SQS. Consumers would handle retries with exponential backoff, use a dead-letter queue for failed messages, and record structured logs and metrics. I would also ensure consumers are idempotent so duplicate deliveries do not create inconsistent outcomes.
I would begin with constrained, measurable use cases such as test generation, documentation updates, or small refactors. The workflow would include repository-specific context, coding standards, architecture guidance, automated linting and test gates, and mandatory human review. I would track quality, review feedback, and defect rates to improve prompts, context, and guardrails over time.
I would evaluate execution duration, traffic patterns, startup latency, dependency size, networking requirements, operational complexity, and cost. Lambda is well suited to event-driven, short-lived workloads with variable demand, while ECS is often preferable for long-running services, predictable APIs, specialized runtimes, or workloads requiring more control over containers and resources.
I would first confirm impact using application metrics, database monitoring, and query logs, then inspect the execution plan to identify missing indexes, inefficient joins, or excessive scans. I would optimize the query and schema carefully, validate the change in a representative environment, and consider caching or read-model approaches where appropriate. The rollout should be monitored with a rollback plan to protect production availability.
I would define clear input and output contracts, use structured output validation, apply safety filters, and provide deterministic fallbacks for critical user flows. I would evaluate prompts against a curated test set, monitor quality and failure patterns in production, and maintain versioned prompts and model configurations. Human escalation or review should be included where errors could have meaningful customer or business consequences.
