This role emphasizes a systematic approach to architecture and scalability, ensuring that distributed systems operate reliably and cohesively. The ideal candidate is a strong technical leader who thrives in a collaborative environment and is passionate about delivering high-quality, customer-centric software. This role also expects fluency in AI-assisted engineering: using coding agents such as Claude Code and GitHub Copilot within a spec-driven workflow, where written specifications, acceptance criteria, and design intent drive agent-generated implementation that the engineer reviews, tests, and remains accountable for. **Essential Duties:** * Lead the design and implementation of complex features and services across the SaaS platform using C# and .NET. * Collaborate with architects and product managers to define technical requirements and system architecture. * Write high-quality, maintainable, and well-tested code across the full stack, including Blazor and [ASP.NET](http://ASP.NET) MVC. * Conduct code reviews and provide technical mentorship to junior and mid-level engineers. * Identify and resolve performance, scalability, and reliability issues in distributed systems. * Contribute to the evolution of engineering best practices, tools, and development processes. * Participate in sprint planning, backlog grooming, and cross-functional technical discussions. * Apply design patterns and SOLID principles to ensure maintainable and extensible code. * Implement unit testing using MSTest, xUnit, or NUnit. * Utilize Domain-Driven Design and microservices architecture to support scalable solutions. * Practice spec-driven development: author precise, testable specifications, acceptance * criteria, and lightweight design docs that AI agents implement against, then review and refine the resulting code. * Use AI coding agents (e.g., Claude Code, GitHub Copilot) to accelerate feature delivery, refactoring, test generation, and documentation, while retaining ownership of correctness, security, and maintainability. * Help establish team standards for AI-assisted engineering, including context and prompt patterns, repository-level agent instructions (e.g., [CLAUDE.md](http://CLAUDE.md), [copilot-instructions.md](http://copilot-instructions.md)), and human review gates for agent-generated code. **Qualifications:** * Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience. * 10+ years of professional software development experience, preferably in a SaaS or cloud-native environment. * Proficiency in **C# and .NET Core/.NET Framework.** * Experience with Microsoft front-end and back-end frameworks including **Blazor and** [**ASP.NET**](http://ASP.NET) **MVC.** * Strong understanding of **RESTful APIs using .NET, microservices architecture, and relational/non-relational databases (e.g., SQL Server, Azure Cosmos DB).** * Experience with version control (Git), CI/CD pipelines (e.g., Azure DevOps), and Agile development practices. **Preferred Qualifications:** * Experience with Microsoft Azure and container orchestration (e.g., Docker, Azure Kubernetes Service). * Familiarity with observability tools (e.g., Azure Monitor, Application Insights) and performance tuning. * Background in SaaS-specific challenges such as multi-tenancy, usage metering, and feature flagging. * Experience with NuGet packages such as AutoMapper, MediatR, FluentValidation, and Entity Framework Core. * Experience with agentic development workflows and tooling (e.g., Claude Code, GitHub * Copilot agent mode, Model Context Protocol servers) integrated into CI/CD. * Experience evaluating AI-generated code for security, licensing, and quality risk, and defining guardrails for team-wide adoption. * Exposure to building AI-enabled product features (e.g., Azure OpenAI, retrieval- augmented generation, prompt orchestration). **Personal Attributes:** **Technical Leader:** You guide others through complex problems and architectural decisions. **Mentor:** You support the growth of your peers and foster a culture of learning. **Customer-Focused:** You build software that solves real problems and delivers value. **Detail-Oriented:** You write clean, maintainable code and test thoroughly. **Collaborative:** You work well across teams and communicate effectively. **Proactive:** You take initiative to improve systems, processes, and team performance. **AI-Leveraged:** You treat AI agents as force multipliers — you specify work precisely, verify output rigorously, and own the result. **Join Us and Enjoy These Perks!** **Competitive Salary:** Earn a USD salary that matches your skills and experience. **Paid Time Off:** Generous PTO to support your work-life balance and recharge. **Health Insurance Subsidy:** Financial assistance to support your healthcare coverage. **Annual Salary Reviews:** Structured annual evaluations to recognize and reward performance. **Paid Training & Certifications:** Continuous support for professional growth and upskilling. *Ready to put your puzzle-solving skills to the test?
