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
