Sr .Net Full Stack Developer

About Spire Soft LLC We are a bootstrapped, remote-first product startup. We build software that works—currently powering productivity through a SaaS suite in the Project Management and Legal-Tech sectors. As we expand, we need builders who thrive with high autonomy. We don’t micromanage; we expect extreme ownership. We hire unconventional thinkers who view "I don’t know" as an invitation to learn and who prefer building products over just "clearing tickets." Roles & Responsibilities The Role We are looking for a .NET Full Stack Software Engineer with 7+ years of experience to build commercial-grade, highly maintainable software. This is a high-visibility role; you will work directly with a 20+ year tech veteran, moving rapidly from concept to production. Key Responsibilities End-to-End Ownership: Manage the full feature lifecycle—from architecture and schema design to deployment and optimization. Architect for Scale: Design performant backend services using .NET Core and C# for our Legal-Tech and Project Management suites. Modernize & Refactor: Lead the evolution of our codebase, transitioning legacy patterns into modern, high-performance architectures. Build Seamless UIs: Develop responsive, "product-first" frontend experiences using Angular and TypeScript. Performance Engineering: Proactively optimize the stack (SQL, API latency, Redis caching) using Azure-native tools. Quality Autonomy: Own your testing strategy (Unit, Integration, TDD) to ensure stability at high velocity. Technical Mentorship: Act as a sounding board for the team through shared learning and rigorous code reviews. DevOps Integration: Refine Azure CI/CD pipelines and cloud infrastructure to keep deployment frictionless. Requirements: Technical Requirements Backend Mastery: 7+ years of expertise in C#, .NET Core/MVC, and building robust Web APIs. Modern Frontend: Proficient in Angular (TypeScript). Familiarity with Vue.js or React is a significant plus. Data Architecture: High proficiency in MS SQL Server, including complex schema design and query optimization. Cloud & Infrastructure: Hands-on experience with Microsoft Azure (App Services, Functions, Service Bus) and containerization (Docker/Kubernetes). Tooling: Proficiency in Python for specialized scripting and a strong grasp of Git-based workflows. Work Authorization Must be a U.S. Citizen or Permanent Resident. No Visa Sponsorship: Please apply only if you are authorized to work in the U.S. without current or future sponsorship. Benefits: Perks & Benefits Direct Mentorship: Daily collaboration with a 20+ year tech veteran. No layers, just direct knowledge transfer. Hybrid Flexibility: We prioritize output and milestones over desk time. Work where you are most productive. Zero Bureaucracy: Fast execution with no approval hurdles. If you have a better way to build it, own it. Performance-Linked Rewards: Bonuses tied directly to product success and company milestones. Modern Tech Stack: Solve real-world problems using the latest tools and high-growth methodologies. Strict Work-Life Balance: 5-day work week (Monday–Friday). Weekends are yours. High-Impact Environment: A startup culture where initiative is the primary currency. Compensation The compensation for this position is $45–$55 per hour, commensurate with expertise, experience, and technical skill set. Preferred: Who Should Apply The "Founding-Mindset" Engineer: You want to build a business, not just a feature. You value learning the "how" and "why" of product strategy directly from a 20-year industry veteran. The Self-Starter: You thrive in ambiguity. If a process doesn't exist, you build it. The Lifelong Learner: You view "bootstrapped" as an opportunity to wear multiple hats—architect, developer, and product thinker. The Quality Obsessive: You write clean, maintainable code because you know you’ll be the one scaling it tomorrow. The Future Leader: You are looking for a path that leads to an Engineering Lead role as the company scales. Who This Is NOT For Preference for Rigid Structure: If you need detailed, pre-written specs for every task, you won't be happy here. Discomfort with "Zero-to-One": This role is for those who enjoy building from scratch with minimal supervision. Silo Seekers: If you prefer the specialized, siloed roles of a large corporation over the broad impact and high visibility of a core product team, this isn't the right fit.
