Senior Software Engineer
Role Overview
We are seeking a hands-on Senior Software Engineer (5–8 years) with strong full-stack skills across C# / .NET and React to build and scale modern enterprise applications.
This role centers on deep development expertise with practical component and application design responsibilities. You will build backend services in C# / .NET and modern frontends in React/TypeScript, contribute to application architecture, and mentor other engineers while staying hands-on. AI is central to how we work and what we build — both as a development accelerator and as a capability within our products.
Key Responsibilities
- Design, develop, and own backend services and APIs using C# / .NET / ASP.NET Core
- Build responsive, maintainable frontends using React and TypeScript
- Use AI coding assistants (e.g., Copilot) to accelerate development, and help build AI-enabled features and intelligent workflows within our products
- Contribute to application and component architecture, including component design, data flows, and integration patterns
- Make sound design decisions at the feature/component level, balancing scalability, performance, maintainability, and delivery speed
- Mentor developers, conduct code reviews, and share technical knowledge while remaining hands-on with coding
- Design and implement data access layers using SQL Server
- Deploy and run applications in the cloud (Azure)
- Ensure best practices in code quality, testing, security, and CI/CD
- Collaborate with product owners and stakeholders to translate requirements into technical solutions
- Troubleshoot production issues and drive performance optimization and reliability improvements
- Promote reusable design patterns and improve overall engineering standards
Required Experience
- 5–8 years of hands-on software development experience
- Strong expertise in:
- C# / .NET / ASP.NET Core
- React and TypeScript
- Web APIs and backend service development
- Entity Framework / Dapper or similar ORM tools
- SQL Server (schema design, query optimization)
- Experience using AI coding tools (e.g., GitHub Copilot) in day-to-day development
- Working knowledge of cloud deployment, ideally Azure (App Service, Azure SQL)
- Good understanding of application architecture, including:
- Layered architecture and separation of concerns
- API design and integration patterns
- Scalability, resilience, and maintainability
- Experience with Git and CI/CD pipelines
- Strong debugging, problem-solving, and performance tuning skills
- Experience working in Agile/Scrum teams
Nice to Have
- Experience building AI-enabled features (e.g., Azure AI / OpenAI APIs, intelligent automation, AI agents)
- Familiarity with observability tools (Application Insights, logging frameworks)
- Caching strategies (e.g., Redis)
- Exposure to event-driven or distributed systems
Ideal Candidate
- Strong full-stack engineer comfortable across C# and React
- Applies sound design principles and owns feature/component design while staying hands-on
- Able to balance speed of delivery with long-term maintainability
- Uses AI fluently as part of their development workflow and is curious about building AI capabilities into products
- Experienced in building cloud-native, data-driven applications
- Effective collaborator with good communication skills
