Remote | AWS Cloud Engineer; Serverless & IaC)

We are sharing a specialised part-time consulting opportunity for experienced AWS Cloud Engineers with strong hands-on expertise in serverless architecture, event-driven systems, infrastructure as code, and multi-service AWS environments.

This role focuses on evaluating technical tasks involving AWS serverless applications and infrastructure-as-code implementations for correctness, architectural quality, reproducibility, and cross-service integration. Selected engineers will review cloud designs, permissions, failure handling, deployment definitions, and testing approaches while providing clear, rubric-based technical feedback.

• Review multi-service serverless applications built on AWS
• Assess architecture involving Lambda, API Gateway, DynamoDB, DynamoDB Streams, S3, Event Bridge, SNS, SQS, and Step Functions
• Evaluate service selection, integration patterns, and architectural trade-offs
• Identify incorrect assumptions or weaknesses in serverless designs
• Assess whether implementations follow sound cloud architecture principles

• Review infrastructure definitions built with AWS CDK, Cloud Formation, or SAM
• Assess whether infrastructure code accurately represents the intended architecture
• Identify configuration errors, missing resources, or incorrect dependencies
• Evaluate deployment structure and infrastructure reproducibility
• Review IaC implementations for consistency and technical correctness

• Evaluate event-driven architectures spanning multiple AWS services
• Review event sources, routing, triggers, subscriptions, and downstream processing
• Assess asynchronous workflows for correctness and resilience
• Identify broken integration patterns or unintended event behaviour
• Evaluate whether service interactions reflect realistic AWS behaviour

• Review IAM roles, policies, and permission boundaries
• Assess whether services receive appropriate access without unnecessary privileges
• Identify missing, excessive, or incorrectly scoped permissions
• Evaluate cross-service authentication and authorisation requirements
• Apply practical AWS security principles when reviewing task implementations

• Assess failure-handling and retry semantics across serverless workflows
• Review dead-letter queues, retry policies, timeouts, and asynchronous failure paths
• Identify scenarios that could cause duplicate processing, lost events, or uncontrolled retries
• Evaluate idempotency and recovery considerations
• Assess whether failure behaviour matches actual AWS service semantics

• Review testing strategies for AWS serverless applications
• Evaluate local development and emulation approaches using tools such as Local Stack
• Identify behavioural differences between emulated environments and real AWS services
• Assess whether local tests provide sufficient confidence in production behaviour
• Review integration and end-to-end testing approaches

• Evaluate integrations between compute, storage, messaging, API, and orchestration services
• Review resource dependencies and service configuration
• Identify mismatches between infrastructure definitions and application behaviour
• Assess data flow across multi-service architectures
• Determine whether integrations function correctly under realistic conditions

• Review logging, monitoring, tracing, and operational visibility where relevant
• Assess whether serverless workloads can be effectively diagnosed in production
• Identify missing observability or operational safeguards
• Evaluate performance and scalability considerations
• Review opportunities for serverless cost optimisation where applicable

• Assess assigned cloud engineering tasks against structured technical criteria
• Provide clear written explanations supporting evaluation decisions
• Reference specific architectural, infrastructure, or implementation evidence
• Apply grading standards consistently across assignments
• Distinguish substantive cloud architecture problems from reasonable alternative designs

• 3+ years of hands-on experience building multi-service AWS serverless applications
• Strong professional experience with AWS Lambda, API Gateway, DynamoDB, S3, Event Bridge, SNS/SQS, and Step Functions
• Strong experience with infrastructure as code using AWS CDK, Cloud Formation, or SAM
• Deep understanding of event-driven architecture
• Strong knowledge of IAM permissions and…
