Principal Software Engineer
Nic MapNIC MAP is committed to creating a diverse environment and is proud to be an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state, or local laws.
NIC MAP is looking for a Principal Software Engineer to join our engineering team. You will design, build, and maintain the software that powers our cloud-based SaaS platform, writing production code, shaping architecture, and keeping things reliable and scalable. We're a small, flat team where titles matter far less than what you ship. You'll own real problems end-to-end and figure out the best path forward, whether that means diving into unfamiliar code, spinning up an AI agent, or pulling in a teammate for a quick design session. We expect AI-forward engineering as a baseline. If you're already using Claude Code or Cursor as a natural part of how you write, debug, and ship, you'll fit here. What You'll Do - Design, develop, and maintain full stack applications using C#, .NET 8+, MSSQL, and PostgreSQL. Front-end work spans Angular, React, Next.js, Vite, Tailwind, and shadcn/ui. Python for data engineering. We pick the right tool for the problem. - Use AI tooling daily (Claude Code, Cursor, AI agents, MCP connectors) to ship faster and eliminate toil. - Architect and deliver solutions across the full stack, owning features from concept through production. - Manage production workloads in Azure, including Azure Container Apps (ACA), monitoring, and operational support. - Debug, troubleshoot, and resolve complex technical issues and production incidents. - Work directly with anyone on the team (engineers, product, leadership) to plan, estimate, and deliver. What We're Looking For - Ownership mentality. You take a task, make it yours, and drive it to completion. - Good judgment about your own limits. When you're out over your skis, you stop and ask questions early. - Fluency with AI-forward tooling (Claude Code, Cursor, AI agents, MCP connectors). You should already be fast with these tools. - Ability to ramp up on unfamiliar domains and technologies quickly through AI-assisted research, rapid prototyping, or whatever gets you there. - Advanced proficiency in C#, .NET, and full stack development. - Strong front-end experience across Angular, React, Next.js, Vite, Tailwind, shadcn/ui, and TypeScript. Depth in a few, and the ability to pick up new ones fast. - Python proficiency for data engineering and analytics workloads. - Solid database design, query optimization, and RESTful API skills (SOLID, Entity Framework Core). - Hands-on Azure experience, including containerized workloads (ACA) and GitHub-based CI/CD. Qualifications - Experience building AI-powered features in production (prompt engineering, RAG, embeddings, document indexing). - GitHub Actions, infrastructure-as-code, or container orchestration in Azure. - Cosmos DB, Service Bus, or other Azure PaaS services. - SaaS product development with multi-tenant architectures. - Healthcare data standards (HL7, FHIR) or data-intensive platforms. - Significant professional experience in software engineering. We care about what you can do. The problems here require senior-level judgment and depth. - Production SaaS experience required. CS degree or equivalent. Why You'll Love Working HereNIC MAP provides data and analytics that drive critical decisions in the seniors housing and care industry. You'll work on meaningful problems with a team that values technical excellence, continuous learning, and real-world impact. - Mission-driven work: your contributions will directly support better housing and care for seniors. - Fully remote: work from home; no mandatory time in the office! - Collaborative team: join a supportive environment where your ideas and skills make a real impact. - Low travel requirements: at most 1–2 trips per year. - Inclusive culture: NIC MAP is proud to be an equal opportunity employer. $165,000 - $185,000 a year If you’re excited about building meaningful technology and want to grow with a team that values innovation, collaboration, and impact, we encourage you to apply. Please note: Applicants must be legally authorized to work in the United States. Unfortunately, NIC MAP is not able to offer visa sponsorship at this time.
