WHY JOIN OUR DREAM TEAM?

The most important part of AppGreat is the team. From our founders to the last person, we are committed to creating a pleasant environment and a place where everybody feels like they belong. We invest in them in any way we can, starting from the amazing atmosphere in the office, unique benefits and career growth opportunities.

We are seeking a hands-on highly technical Full Stack Tech Lead (React, Node.js, Cloud infrastructure) to anchor our engineering efforts and collaborate directly with executive leadership. In this heavily technical role (roughly 90% coding and architecture, 10% mentorship), you will drive technical execution within a flat structure - writing high-impact code, designing systems, and using modern AI tooling to accelerate delivery. You’ll lead by example through technical excellence and architectural standards, providing lightweight mentorship while aligning technology with C-level business goals.

YOUR MISSION:

• Serve as the primary individual contributor on the team, writing clean, scalable, and maintainable code across the stack every day.
• Actively and mandatorily utilize AI coding assistants (e.g., GitHub Copilot, Cursor, ChatGPT, Claude) to accelerate development, automate boilerplate, and optimize problem-solving.
• Build responsive, highly interactive user interfaces using React, TypeScript, and modern state management libraries.
• Develop secure, performant, and reliable backend services, microservices, and REST/GraphQL APIs using Node.js.
• Drive the architectural design and system roadmap for high-traffic applications, making strategic decisions regarding state management, database schema design, and cloud infrastructure provisioning.
• Actively identify, document, and refactor technical debt to ensure long-term system health and scalability.
• Optimize CI/CD pipelines, deployment processes, and application monitoring to ensure high availability and smooth releases in cloud environments.
• Partner with executive leadership to turn business goals into scalable technical roadmaps and architectures.
• Set the standard for code quality and testing through hands-on leadership and AI-augmented code reviews.
• Mentor engineers, unblock technical hurdles, and break down complex features for rapid delivery.

WHAT YOU WILL BRING TO THE COMPANY:

• 5+ years of professional software engineering experience, with a proven track record as a Senior Engineer, Principal Engineer, or Technical Lead setting technical direction.
• Hands-on, production-level experience architecting and deploying to major cloud platforms (AWS, GCP, or Azure) is an absolute must.
• Strong proficiency with containerization (Docker) and modern CI/CD practices.
• Demonstrated daily usage and high proficiency with AI development tools (e.g., Cursor, GitHub Copilot, ChatGPT, or Claude).
• Strong, up-to-date proficiency in React, its core principles, and modern hooks. Experience with Next.js, Redux, or Zustand is a strong plus.
• Deep understanding of Node.js and its ecosystem (Express, NestJS, etc.).
• Proven experience building secure and scalable APIs.
• Advanced proficiency in TypeScript and modern JavaScript (ES6+).
• Solid hands-on experience with both relational (e.g., PostgreSQL, MySQL) and NoSQL (e.g., MongoDB, Redis) databases, including complex query optimization.

NICE TO HAVE/ADVANTAGE:

• A "builder" mentality with a strong bias for action and a deep passion for writing elegant, efficient code.
• Exceptional problem-solving skills and the ability to debug complex issues across the entire stack.
• Strong executive communication skills, capable of articulating technical trade-offs directly to business leaders and founders.
