You will own features end-to-end - from database schema and C# service layer through Angular UI - and drive AI-assisted engineering practices (GitHub Copilot, Copilot Chat, prompt-driven development) across the team. You will be a technical leader on SOLID design, clean architecture, and secure, scalable cloud-native systems.\n\nWhat You Will Do\n\n* Design and build production-grade full-stack web applications using C# / .NET 8+, ASP.NET Core Web API, Entity Framework Core, and Angular 17+.\n* Model, tune, and evolve relational schemas in SQL Server / PostgreSQL and integrate with Aurora / RDS in AWS.\n* Architect for AWS deployment: API Gateway, Lambda, ECS/EKS on Fargate, S3, SQS/SNS, EventBridge, Secrets Manager, CloudWatch, KMS.\n* Apply SOLID, Clean Architecture, and Domain-Driven Design principles; enforce them through code reviews and pair programming.\n* Drive AI-assisted development across the team - GitHub Copilot / Copilot Chat, prompt libraries, code-generation guardrails, secure prompt patterns, and test generation.\n* Integrate LLM-powered capabilities into applications (chat, summarization, classification, RAG) via Azure OpenAI / AWS Bedrock; wire PII / PCI / PHI guardrails at the prompt boundary.\n* Write and maintain unit, integration, and contract tests (xUnit / NUnit, Jasmine / Karma, Playwright); target 80%+ coverage on core services.\n* Own CI/CD in Azure DevOps or GitHub Actions with build -> test -> security scan -> deploy to AWS via CDK or Terraform.\n* Instrument with OpenTelemetry; publish metrics/traces to CloudWatch + Managed Grafana.\n* Partner with architects, product owners, and QA to break epics into deliverable sprint work; mentor 2-4 mid-level engineers.\n* Participate in on-call rotation for owned services (business-hours primary, off-hours secondary).\n\nRequired Skills & Experience\n\n* 8+ years professional software engineering; 5+ years on C# / .NET production applications.\n* Strong ASP.NET Core Web API and Entity Framework Core; async/await, dependency injection, minimal APIs, middleware pipeline.\n* Angular 15+ production experience: components, RxJS, NgRx or Signals, standalone components, reactive forms, lazy-loaded modules, unit testing.\n* Deep relational database skills: schema design, indexing, query tuning, execution plans, stored procedures, migrations. SQL Server and at least one of PostgreSQL / MySQL.\n* Practical AWS cloud experience deploying real workloads: IAM, VPC, API Gateway, Lambda or ECS/EKS, RDS/Aurora, S3, SQS/SNS, CloudWatch, Secrets Manager, KMS.\n* Demonstrable command of SOLID principles, design patterns (Repository, CQRS, Mediator, Strategy, Factory), and clean-architecture layering.\n* AI-assisted development fluency: using GitHub Copilot / Copilot Chat daily as a productivity tool - writing effective prompts, evaluating suggestions critically, generating tests, refactoring, and documenting via AI. Ability to coach others in the same.\n* Experience integrating with LLM APIs (Azure OpenAI, AWS Bedrock, or OpenAI) and applying safety patterns (input validation, PII redaction, output filtering, prompt-injection defenses).\n* Strong Git workflow, code review discipline, and comfort with trunk-based or GitFlow branching.\n* Excellent written and verbal communication; ability to write design docs, ADRs, and runbooks.\n\nPreferred / Nice-to-Have\n\n* AWS certification (Developer Associate, Solutions Architect Associate, or higher).\n* Docker + Kubernetes hands-on (EKS, Helm).\n* IaC with AWS CDK (TypeScript / C#) or Terraform.\n* Event-driven architecture experience (EventBridge, Kafka / MSK, Kinesis).\n* Micro-frontend or module-federation experience.\n* Vector databases (pgvector, OpenSearch, Pinecone) and RAG pipelines.\n* Regulated-industry background (banking, healthcare, insurance) with awareness of SOC 2, PCI-DSS, HIPAA constraints.\n* Contributions to open-source .NET or Angular projects.\n\nPay: $50.00 - $70.00 per hour\n\nBenefits:\n* Dental insurance\n* Health insurance\n* Vision insurance\n\nWork Location: In person","company":"Advantage Tech","rawCompany":"advantage tech","city":"Kansas City","state":"MO","isRemote":false,"isActive":false,"createdAt":"2026-09-17T10:50:34.532Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1254.00","title":"Web Developers","slug":"web-developers"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Full Stack Developer","description":"*\\*\\* THIS IS A 9-12 MONTH CONTRACT \\*\\**\n\nAbout the Role\n\nWe are hiring a Software Engineer to design and build enterprise full-stack web applications from our on-premise engineering center, delivered onto AWS Cloud.
