Software Engineer II / Mid-Level Software Engineer
About The Position
We’re a software company at the start of building a brand-new, highly visible SaaS application. This is an exciting opportunity to join early and contribute to the technical foundation of a new product while learning from experienced engineers and helping deliver core product capabilities. We’re looking for a motivated mid-level engineer who is comfortable building production software and is excited to work with an AI-first mindset. You should be curious about agentic AI workflows, automation, and modern AI development tools, and eager to use them responsibly to improve productivity, testing, documentation, and software quality. This project will use an AI-Development Life Cycle, or AI-DLC, to help drive the creation, testing, and deployment of the application. You’ll be fully supported in using AI-assisted development practices as part of your day-to-day engineering workflow. In this role, you’ll help design, build, test, and maintain backend systems using .NET/C# and modern architectural patterns such as Event Sourcing, CQRS, Domain-Driven Design, and Vertical Slice architecture. You’ll work in a cloud-native environment using AWS, PostgreSQL, RabbitMQ, and Docker, contributing to a platform built for scale, reliability, and rapid iteration. This is a strong fit for an engineer who has solid professional experience, can work independently on well-defined features, collaborates well with senior engineers, and is ready to grow into deeper technical ownership over time.
Requirements
- Professional experience building production software with C#/.NET
- Solid understanding of backend development, APIs, data persistence, and service design
