Remote | AWS Cloud Engineer (Serverless & IaC) — $60–$80/hour

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. Key Responsibilities AWS Serverless Architecture Review multi-service serverless applications built on AWS Assess architecture involving Lambda, API Gateway, DynamoDB, DynamoDB Streams, S3, EventBridge, 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 Infrastructure as Code Review infrastructure definitions built with AWS CDK, CloudFormation, 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 Event-Driven Systems 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 IAM & Security Boundaries 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 Failure, Retry & Recovery Behaviour 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 Testing & Local Emulation Review testing strategies for AWS serverless applications Evaluate local development and emulation approaches using tools such as LocalStack 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 Cross-Service Integration 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 Observability & Operational Quality 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 Rubric-Based Technical Evaluation 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 Ideal Profile 3+ years of hands-on experience building multi-service AWS serverless applications Strong professional experience with AWS Lambda, API Gateway, DynamoDB, S3, EventBridge, SNS/SQS, and Step Functions Strong experience with infrastructure as code using AWS CDK, CloudFormation, or SAM Deep understanding of event-driven architecture Strong knowledge of IAM permissions and security boundaries Experience designing and evaluating failure, retry, and recovery behaviour in distributed systems Familiarity with LocalStack or comparable local AWS testing approaches Ability to distinguish local emulation behaviour from actual AWS service behaviour Strong cloud architecture, debugging, and technical review skills AWS certifications such as Solutions Architect or Developer are advantageous Experience with serverless observability and cost optimisation is preferred Previous code-review or technical task-grading experience is advantageous Strong written communication and ability to provide precise technical feedback Engagement Details Part-time independent contractor engagement Fully remote within the United States Flexible scheduling based on project requirements Compensation:
