 * Tooling: Proficiency in Python for specialized scripting and a strong grasp of Git-based workflows.

## Description

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., * 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., * 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.
