Principal Software Engineer

Role Overview

• Strategic Modernization & Growth: Partner with customers to assess current technology estates.
• Lead engineering efforts to refactor legacy systems and architect new features that drive measurable business outcomes and scalability.
• Provide clarity and direction within ambiguous or evolving problem spaces.
• Spec-Driven Development (SDD): Lead a "spec-first" or "spec-as-source" methodology using Generative AI.
• Create structured, behavior-oriented specifications (requirements and designs) that serve as the primary source of truth, guiding AI agents to generate, verify, and maintain implementation code.
• Ensure that generated code, tests, and documentation align with the spec and architectural standards.
• Architectural Leadership: Design scalable, resilient systems.
• Translate complex business requirements into technical specifications that AI agents and engineering teams use as the foundation for development.
• Review implementations to ensure alignment with patterns, performance, and security expectations.
• AI-Assisted Engineering: Integrate AI tools like Cursor, Claude Code, GitHub Copilot, Speckit into development workflows.
• Evolve engineering practices from manual coding to auditing, validating and refining AI-generated solutions based on rigorous specifications.
• Establish repeatable AI-driven development patterns.
• Polyglot Development: Evaluate and implement production-grade code across multiple languages and paradigms (e.g., TypeScript, Python, Go, .NET, Java) based on specific problem domains.
• Ramp quickly into unfamiliar stacks or codebases to provide clarity and direction.
• Technology Evaluation: Rapidly assess new technologies, frameworks, and patterns to determine viability and production readiness.
• Make informed recommendations balancing performance, maintainability, and team skill sets.
• Mentorship: Raise and maintain the engineering bar through code reviews, architectural designs, and mentoring other engineers on the team.
• Help engineers adopt SDD, AI-assisted workflows, and modern architectural practices.

Requirements

• 10+ Years of Experience: Proven experience as a Senior/Principal Engineer or Software Architect delivering complex distributed systems.
• Full Stack Mastery: Deep expertise in both frontend and backend development.
• Frontend: Advanced proficiency with modern JavaScript/TypeScript frameworks (e.g., React, Next.js, Vue, Svelte), state management, and modern CSS workflows (Tailwind, CSS-in-JS).
• Backend: Robust experience designing APIs (REST, GraphQL, gRPC) and server-side architecture using languages such as Node.js, Go, or Python.
• Polyglot Proficiency: Proficiency in at least three distinct programming languages (e.g. TypeScript, Python, Go, .NET, Java).
• Generative AI & SDD Experience: Experience utilizing Spec-Driven Development tools and workflows where specifications (natural language or structured docs) drive AI code generation.
• Business-Aligned Engineering: Demonstrated ability to align technical refactoring and feature development with customer business goals and growth metrics.
• Rapid Skill Acquisition: Ability to quickly acquire proficiency in unknown codebases or new languages.
• System Design: Knowledge of microservices, event-driven architecture, cloud-native patterns (Kubernetes, Docker), and database internals (SQL & NoSQL).
• Experience Cloud Providers: AWS or Azure
