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

Why Workfully

We’re a small, product-driven team building technology that changes how recruiting works. You’ll have the autonomy to make decisions, see your impact fast, and work alongside a group of people who care deeply about what they build. xqbhyrx
