Full Stack Engineer

Company: TechThrone

Location: Romania (Fully Remote)

Type: B2B Contract

We are looking for a Full Stack Engineer with strong TypeScript, React, and Node.js skills to join TechThrone, a fast-growing startup building innovative digital products for a global customer base.

This is an exciting opportunity to play a core role in building and scaling our platform. Working across a React front end and Node.js back end, you'll have high autonomy, own features end-to-end, and help shape our engineering culture in a fast-paced startup environment.

The Role

As a Full Stack Engineer, you will:

• Design and build scalable, high-performance web applications using TypeScript, React, and Node.js.

• Take full ownership of features from concept and architecture to production deployment.

• Build modular UI components and maintain robust, low-latency APIs.

• Collaborate directly with product and design to iterate rapidly on new product initiatives.

• Champion front-end performance, backend reliability, and clean code standards across the codebase.

• Contribute to technical decisions, architecture, and developer tooling.

About You

You are a full-stack engineer who thrives in an early-stage or high-growth startup setting. You bring strong product instincts, enjoy taking initiative, and excel at shipping clean, maintainable TypeScript across the entire stack.

Skills & Experience

Essential

• 4+ years of commercial experience in full-stack software development.

• Deep expertise in TypeScript across both front-end and back-end environments.

• Strong hands-on experience with modern React (state management, performance tuning, component architecture).

• Solid backend experience with Node.js (Express, NestJS, or similar frameworks).

• Proven track record designing and consuming REST or GraphQL APIs.

• Experience working with relational databases (e.g., PostgreSQL).

• Comfort with startup ambiguity, fast iteration cycles, and high ownership.

• Strong communication skills and a proactive approach in remote teams.

Desirable

• Experience with Next.js, SSR, or modern React frameworks.
• 
  
• Exposure to cloud infrastructure (AWS/GCP), Docker, and CI/CD pipelines.

• Experience with automated testing tools (Vitest, Jest, Playwright).

• Familiarity with state management tools (Zustand, React Query).

• Practical use of AI-assisted dev tools (GitHub Copilot, Cursor, Claude code) to boost velocity.
