At Workfully , we’re building the first general recruitment marketplace where independent recruiters can grow, engage, and monetize their talent networks — connecting them to meaningful opportunities at innovative companies worldwide.
Our technology is designed to make recruiting more transparent, fair, and scalable. We’re a profitable early-stage company with clients like TravelPerk, OLX, Accenture, Inditex, and FreeNow , and we’re now expanding our engineering team to build the next generation of the Workfully platform.
The Role
We’re looking for a Senior Fullstack Engineer who’s passionate about product, user experience, and applied AI .
You’ll work end-to-end across the stack — from concept and design discussions to production-ready delivery — building features that make our platform smarter and more intuitive. You’ll collaborate with product and design early in the process, experiment with LLMs, embeddings, and semantic search , and help us bring real AI value into recruiting.
What You’ll Do
- Deliver features end-to-end across frontend and backend




- Collaborate with product and design during discovery and planning
- Integrate AI components (LLMs, embeddings, semantic search) where they add value
- Contribute to architectural discussions and ensure technical scalability
- Maintain high standards of code quality, performance, and testing

Our Stack
We work with a modern TypeScript-based stack:
- Frontend: React, Next.js, TailwindCSS
- Backend: NestJS, Sequelize, MariaDB / PostgreSQL
- Infrastructure: AWS (ECS, EC2, S3, CloudWatch), Docker, Auth0
- Testing & CI/CD: Jest, Testing Library, GitHub Actions
- Principles: SOLID, Domain-Driven Design, Clean / Hexagonal Architecture

Who You Are
- You thrive in fast-moving environments and enjoy building real products
- You’re curious about applied AI and eager to use it beyond experiments
- You’re pragmatic about trade-offs and focused on impact
- You value clean, maintainable code and collaborative teamwork
