Key required skills

We're seeking a Senior AWS Engineer to lead the development of resilient, event-driven cloud applications using modern serverless technologies. This is a critical hands-on engineering role with architectural influence-ideal for someone who thrives undistributed systems, ultra-low RTO/RPO environments, and production-scale AWS solutions.

As a Senior AWS Engineer, you'll architect and build multi-region, low-latency applications that are designed for high availability, minimal data loss, and rapid recovery. You'll work heavily with AWS Lambda, Step Functions, and DynamoDB to construct loosely coupled, fault-tolerant systems that handle critical workloads and real-time data flows.

You'll also apply your expertise in building cloud-native apps that meet aggressive RTO (Recovery Time Objective) and RPO(Recovery Point Objective) goals, often in environments where global consistency, availability, and durability are non-negotiable.

As a Senior AWS Engineer, you will:

• Design and implement highly resilient, event-driven architectures using AWS Lambda and Step Functions
• Build serverless applications with scalable APIs, asynchronous workflows, and fault-tolerant patterns
• Leverage DynamoDB (including advanced partitioning strategies) to handle real-time data and state at scale
• Work around current AWS limitations (e.g., DynamoDB Global Tables not yet GA) to build multi-region solutions with low RPOand high durability
• Architect systems for low RTO/RPO disaster recovery, leveraging cross-region failover strategies and automation
• Implement observability and alerting using CloudWatch, X-Ray, and third-party monitoring tools
• Automate infrastructure with IaC tools like AWS CDK, Terraform, or CloudFormation
• Optimize cold-start performance, event retries, and workflow orchestration for high-throughput environments
• Collaborate with product, backend, and platform teams to integrate infrastructure into CI/CD workflows
• Contribute to cloud engineering best practices, including secure defaults, cost optimization, and environment parity
• Mentor fellow engineers on cloud architecture and resilience engineering patterns

You'll bring:

• 8+ years of software engineering experience, including 3+ years building production systems on AWS
• Deep hands-on experience with AWS Lambda, Step Functions, and DynamoDB
• Expertise in designing low RTO/RPO systems, multi-region architectures, and fault-tolerant workflows
• Familiarity with the current limitations around DynamoDB Global Tables and experience implementing workarounds
• Experience building real-time or near real-time event-driven systems (e.g., using SQS, SNS, EventBridge, Kafka (MSK))
• Strong proficiency in scripting and backend languages such as Java, Python, Node.js, or Go
• Experience with infrastructure as code (IaC) using CDK, Terraform, or CloudFormation
• Solid understanding of distributed system design, idempotency, retries, and failure recovery
• Strong communication and consulting skills with the ability to lead architecture discussions with stakeholders

Added Advantage:

• Experience building for regulated industries or high-compliance environments (e.g., finance, healthcare)
• AWS Solution Architect Associate certification

Key Skills:

Lambda, Step Functions, DynamoDB, AWS, Cloud Formation
