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.
