Software Engineer

We’re looking for a Software Engineer who can design, build, and operate cloud-native services on AWS. You’ll work primarily in C#/.NET MVC/Web Forms apps with supporting services in Node.js/TypeScript. Your day-to-day will include building APIs and event-driven workloads using API Gateway, Lambda, EventBridge, and S3, backed by modern CI/CD and infrastructure-as-code. 

What you’ll do 

• Design & build RESTful APIs and microservices in C#/.NET and Node.js/TypeScript running on AWS Lambda behind API Gateway. 

• Model, publish, and consume events (EventBridge/SNS/SQS) to enable decoupled, event-driven architectures; implement idempotency, retries, DLQs, and observability. 

• Work with storage: DynamoDB (NoSQL), RDS (SQL Server), S3 for object storage, and caching. 

• Own the SDLC: write clean, testable code;maintain high standards; ship via CI/CD. 

• Instrument and operate services in production with CloudWatch, X-Ray, structured logging, and alarms; participate in a lightweight on-call rotation and post-incident reviews. 

• Collaborate cross-functionally with product, QA, and DevOps to refine requirements, estimate work, and deliver incrementally. 

• Continuously improve performance, reliability, and AWS cost efficiency; profile hot paths and tune queries/indexes. 

• Document APIs with OpenAPI/Swagger; write concise runbooks and ADRs for key decisions. 

Required qualifications 

• 3–5 years professional software engineering experience with a strong focus on C#/.NET  

• Hands-on AWS experience building serverless backends with API Gateway, Lambda, EventBridge, and S3. 

• Practical Node.js/TypeScript experience (building utilities, Lambdas, or services). 

• Solid understanding of HTTP, REST, JSON, async programming, and common integration patterns (webhooks, polling, callbacks). 

• Experience with relational SQL (SQL Server) and at least one NoSQL store (DynamoDB preferred). 

• Comfortable with git, trunk/PR workflows, and CI/CD pipelines. 

• Proficient in unit/integration testing, mocking, and test data strategies. 

• Strong debugging skills across cloud logs/metrics/traces; familiarity with CloudWatch/X-Ray. 

• Clear written and verbal communication; collaborative mindset and ownership mentality. 

Preferred Experience:

• AWS Step Functions, SNS/SQS, Kinesis, or Kafka experience. 

• Infrastructure as Code with AWS CDK (TypeScript/C#) or Terraform at scale. 

• Observability with OpenTelemetry, structured logging, and distributed tracing. 

• Security: Cognito, custom JWT authorizers, WAF, Secrets Manager, parameterized/IaC-managed IAM. 

• API design: pagination, filtering, versioning, OpenAPI first; gRPC familiarity a plus. 

• Frontend integration understanding (CORS, rate limiting, API keys, 429 strategies). 

• Container basics (Docker), ECS/Fargate or EKS exposure. 

• Performance tuning (.NET profilers, async best practices, DynamoDB access patterns). 

• Experience in high-throughput transactional systems or B2B integrations.
