Senior AWS Application Engineer

Overview

Senior AWS Application Engineer who designs, builds and ships serverless applications and APIs on AWS for enterprise clients, owning technical delivery from design through production.

What you'll do

• Design and build serverless applications: develop scalable, event-driven services using AWS Lambda, API Gateway, Step Functions, EventBridge, SQS, SNS and DynamoDB.
• Build and manage APIs: design, implement and document secure, well-versioned RESTful and GraphQL APIs (API Gateway, AppSync) with attention to performance, authentication and developer experience.
• Write high-quality, maintainable code in Python or Node.js/TypeScript, applying unit and integration testing, code reviews and clear documentation.
• Automate infrastructure and deployments: define and manage environments with infrastructure as code (AWS CDK, CloudFormation, SAM or Terraform) and build CI/CD pipelines for fast, safe, repeatable releases.
• Champion security, reliability and observability: apply AWS Well-Architected principles, IAM least privilege, encryption and secrets management, and instrument systems with CloudWatch, X-Ray and structured logging.
• Optimize performance and cost: tune serverless workloads for latency, concurrency and cost, troubleshoot production issues and drive continuous improvement after go-live.
• Partner with clients and internal teams: take part in discovery and design sessions, translate requirements into technical solutions, provide accurate estimates and communicate progress and risks to technical and non-technical stakeholders.
• Lead and mentor engineers through code reviews, pairing and technical direction, and contribute reusable patterns, accelerators and engineering standards to the practice.
• Integrate with enterprise ecosystems such as CRM, ticketing and contact center systems, including Amazon Connect where applicable.
