Summary: Seeking a Senior Full-Stack Software Engineer to accelerate product roadmap delivery, contributing across the entire stack in a lean, high-output internal software team. Highlights: 1. High-impact role contributing across the entire stack from day one. 2. Modern TypeScript stack with AI-forward engineering culture. 3. Fully remote, flexible work with direct collaboration opportunities. **About Our Client**Our client is building a lean, high\-output internal software team with startup energy and private\-equity urgency. They are a lean, high\-performing engineering team of seven building cloud\-native software on a modern TypeScript stack. They ship fast, own their outcomes, and lean heavily on automation and AI\-augmented workflows (including Claude Code). This is a startup working environment within a larger company. We’re hiring a senior full\-stack engineer to accelerate delivery on their product roadmap. This is a high\-impact role where you’ll contribute across the entire stack from day one. **Role Overview** As a Senior Full\-Stack Software Engineer, you will design, build, and ship features end\-to\-end across our React single\-page application and Node.js backend. You’ll work directly with the product owner and engineering manager to translate product requirements into production\-ready code. This is a contract engagement with a strong path toward extension for the right candidates. **Key Responsibilities** * Strong enough technically to read, modify, and fix production code * Comfortable working with AI\-assisted / “vibe\-coded” prototypes and turning them into maintainable systems * Organized, decisive, and comfortable driving timelines without being spoon\-fed * Assertive enough to push execution forward when ambiguity exists * Architect, develop, and maintain features across the full stack (React SPA front end and Node.js/Express/TypeORM backend) * Write clean, well\-tested TypeScript code and participate actively in code reviews * Design and optimize PostgreSQL and SQL Server database schemas, queries, and migrations * Collaborate closely with the product owner, engineering manager, and fellow engineers in an agile, async\-first remote environment * Contribute to CI/CD pipelines (GitHub Actions) and containerized deployment workflows * Identify and resolve performance bottlenecks, scalability issues, and technical debt * Mentor teammates and help establish best practices as the team scales * Participate in architecture discussions and contribute to technical direction **Required Qualifications** **Technical Skills** * **TypeScript / JavaScript** – Deep, production\-level fluency across both front\-end and back\-end contexts * **React** – Strong experience building and maintaining SPAs; familiarity with state management (Jotai preferred), data\-fetching libraries (TanStack), and form handling (React Hook Form) * **Node.js \& Express** – Solid backend experience designing RESTful (or GraphQL) APIs * **SQL / Relational Databases** – Proficient with PostgreSQL (primary) and/or SQL Server; experience with ORM tools (TypeORM preferred) * **TailwindCSS** – Comfortable building responsive, utility\-first UIs * **Git \& CI/CD** – Strong Git workflow; experience with GitHub Actions or equivalent * **Containerization** – Experience with Docker and containerized deployments **Experience** * 5\+ years of professional software engineering experience, with at least 3 years in a full\-stack role * Familiarity with AI\-augmented development workflows (e.g., Claude Code, Copilot, Cursor) * Proven track record of shipping production software in fast\-paced, small\-team environments * Comfortable operating autonomously in a fully remote, async\-first setting * Strong written and verbal communication skills * Pragmatic engineering mindset: you ship incrementally, proactively test\+validate, and avoid over\-engineering * Experience with cloud\-native development on Azure (deployments, configurations, managed services, etc.) * Geospatial development experience with Mapbox and/or turf.js * Experience with TypeORM specifically * Prior work in contract\-to\-hire or high\-growth startup environments **Tech Stack Overview** Below is a summary of our current and directional stack. You don’t need experience with every tool, but you should be comfortable across most of the core technologies. **Layer** **Technologies** **Frontend** React (SPA), Tailwind CSS, TanStack, Jotai, React Hook Form **Backend** Node.js, TypeScript, Express, TypeORM **Data** PostgreSQL (primary), SQL Server **Infrastructure** Cloud\-native, GitHub Actions (CI/CD), Containerized deployments **Mapping (Bonus)** Mapbox, turf.js **What We Offer** * Fully remote, flexible work arrangement * A small, senior team where your contributions are visible and valued from day one * Modern TypeScript stack with minimal legacy baggage * AI\-forward engineering culture (Claude Code is part of the workflow) * Strong path to contract extension for high performers * Direct collaboration with the product owner and engineering leadership
