Role: Principal Software Engineer
Location: REMOTE
Fulltime
TECHNICAL SKILLS
AI-Driven Development
- Hands-on fluency with AI-assisted development tools — using them daily and understanding their strengths, failure modes, and appropriate limits.
- Experience building and orchestrating agents: designing agent loops, managing context and memory, composing multi-step pipelines from discrete skills, and handling failure modes gracefully.
- Ability to define reusable, well-scoped skills with clear interfaces and predictable behavior — the building blocks of reliable agentic workflows.
- Prompt engineering as a first-class discipline: structured prompting, output validation, iterative refinement, and the ability to teach these practices to others.
- Practical experience evaluating agent behavior: defining what good looks like, building evals, and holding AI-generated work to the same standards as hand-authored code.
- Ability to identify which parts of a development workflow are good candidates for automation or AI assistance and which are not.
Cloud Native & Platform
- Strong working command of containerization and orchestration — building and running services that are scalable, reliable, and operationally simple.
- Experience with major cloud platforms and their managed services, with a preference for platform native solutions over custom infrastructure.
- Infrastructure as code practices applied consistently across environments.
- Building and maintaining CI/CD pipelines with an emphasis on fast feedback, automated quality gates, and safe deployment patterns.
- Distributed systems fundamentals applied in practice: service communication, event-driven patterns, observability, and fault tolerance.
Application Development
- Deep expertise in C# / .NET — platform internals, async programming, and performance optimization.
- API design and implementation using ASP.NET Core, including REST principles, versioning, and middleware patterns.
- Relational database design, ORM usage, and T-SQL query optimization.
- Front-end development with React and TypeScript, including component design and state management patterns.
- Proficiency with modern JavaScript/TypeScript, HTML, and CSS.
Tooling & Quality
- Performance profiling and analysis across both server and client layers.
- Comprehensive testing strategies spanning unit, integration, and end-to-end coverage.
- Security fundamentals: secure coding practices, secrets management, and awareness of common vulnerability classes.
