Staff Software Engineer [.Net, MVC, AWS, AI]

You’ll shape the future of a business‑critical platform as the technical lead across both product engineering and cloud infrastructure. You’ll modernize a mature .NET application running on AWS today, while steering its evolution toward a cloud‑native, React/Node.js, AI‑enabled architecture. If you enjoy owning architecture end‑to‑end, from backend and frontend through CI/CD, DevOps, and AWS infrastructure, this role gives you real influence at Staff Engineer level and the opportunity to set engineering standards that others follow.

You’ll spend your time leading complex .NET and React features, designing scalable AWS infrastructure with Infrastructure as Code, and building automation that makes releases fast, safe, and repeatable. You’ll work on performance, reliability, and modernization in equal measure—fixing what’s slowing the platform down today and designing what it will look like in the next generation.

Here’s a breakdown of what you’ll do (not all of it, just the important stuff)

Lead the architecture and development of enterprise .NET services and APIs that power a business‑critical platform.

Design and operate AWS infrastructure (using AWS CDK in TypeScript) to support secure, scalable, multi‑environment deployments.

Build and optimize CI/CD pipelines (AWS CodePipeline, CodeBuild, Windows build agents) to make shipping .NET and React changes fast and reliable.

Drive modernization initiatives across the stack, including clean architecture, refactoring legacy components, and reducing technical debt.

Design and tune PostgreSQL and MSSQL database solutions for performance, scalability, and reliability.

Mentor engineers and influence engineering practices across teams, raising the bar on cloud, DevOps, and software design.

These are the essentials you’ll need to get an interview

Significant experience (typically 8+ years) delivering and operating scalable enterprise software, owning both application code and cloud infrastructure.

Deep hands‑on expertise with C# and .NET (including ASP.NET MVC and enterprise backend architecture).

Strong experience running production workloads on AWS, including core services such as EC2/ECS/Lambda, S3, IAM, VPC, and CloudWatch.

Proven track record designing and improving CI/CD pipelines and deployment automation for complex applications.

Solid experience with React and TypeScript, and building frontends that integrate with .NET backends and REST APIs.

Strong understanding of modern software design principles (e.g. SOLID, clean architecture) and how to apply them in large systems.

Experience leading technical initiatives and mentoring other engineers, with the ability to influence engineering standards beyond your own team.

It would be great if you had these too, but we’ll support you if you don’t

Experience with containerized workloads and modern DevOps tooling (e.g. Docker, ECS, GitHub Actions, observability platforms like Datadog or Grafana).

Exposure to security, compliance, or cost‑optimization in the cloud (e.g. SOC 2/ISO, FinOps, multi‑account AWS setups).

Familiarity with Node.js and AI/ML integrations (for example AWS Bedrock or RAG‑style systems) and an interest in helping shape a MERN‑oriented, cloud‑native future state.
