Job Description
Backend / Full-stack Engineer, TypeScript, AI-assisted
Laba
• Read and build a reliable mental model of the existing TypeScript / Next.js codebase — its architecture, data flows, and business logic. • Own and improve technical documentation across architecture, data flows, business logic, and key system processes. • Design, develop, and ship backend and full-stack functionality for Command Center and other internal tools. • Maintain server-side logic, APIs, PostgreSQL data access, and authorization; build React / Next.js components as full-stack tasks require. • Write, optimize, and review SQL queries, and maintain integrations between internal systems, databases, and business workflows. • Drive code quality through deliberate refactoring, cleaner structure, and simpler, more maintainable logic. • Leverage AI tools (Claude, ChatGPT, Cursor, GitHub Copilot) for code comprehension, debugging, refactoring, documentation, and test generation. • Automate recurring processes and propose practical improvements to internal workflows. • Contribute to technical discussions with data, analytics, finance, recruitment, and other business teams
Job Requirements
- Commercial experience with TypeScript / JavaScript (backend or full-stack).
- Experience with React and Next.js, including a working understanding of the App Router and Server Components / Server Actions (or clear readiness to ramp into them quickly).
- Confident working within an established codebase — reading it, understanding how it fits together, and improving it.
- Solid understanding of server-side logic, APIs, databases, and authorization principles.
- Practical SQL experience with relational databases, preferably PostgreSQL.
- Experience with Git, code review, and independent debugging / root-cause investigation.
- Hands-on experience using AI tools in development, with the judgment to review, test, and understand AI-assisted code.
- Comfortable working with internal tools, data-rich applications, and business logic; eager to learn fast and grasp business context.
- 1-2+ years of commercial experience in backend, full-stack, or TypeScript-focused roles.
- NextAuth / OAuth / JWT / Google OAuth / role-based access (nice to have).
- GCP, Cloud SQL, service accounts, Vercel deployments (nice to have).
- Zod or other validation libraries; Vitest / Jest (nice to have).
- Experience inheriting and refactoring AI-generated / "vibe-coded" projects (nice to have).
- PostgreSQL views, migrations, query optimization (nice to have).
- AI / LLM API integrations (Anthropic, OpenAI, Gemini) (nice to have).

- No micromanagement or bureaucracy — only automated processes. Feel free to experiment, propose, and implement your ideas.
- We champion a proactive mindset, bold ideas, and a willingness to embrace change. Laba isn’t about going with the flow — it’s about pushing the world forward.
- We provide only up-to-date insights from market experts—knowledge that can be immediately applied in practice, transforming workflows even during the learning process. Our products are designed for decisive action in business and careers.
