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: $60–$80/hour
-
Work focuses on AWS serverless architecture, infrastructure as code, event-driven systems, integration correctness, and technical quality evaluation
-
Projects may be extended, shortened, or concluded based on project needs and performance
-
Work must be completed without using confidential or proprietary information belonging to any employer, client, institution, or other third party
-
H1-B and STEM OPT support is unavailable for this engagement
