React API Node.js Agile Angular GraphQL Microservices AWS DevOps Kafka DDD Office

Hi! 👋🏼

At Shakers, we're on the lookout for a Full Stack Dev Junior to take our Product Team to the next level 🚀

If you have experience in Developing reliable services based on Node.js and Next.js, thrive in a dynamic startup environment, and are ready to take your career to the next level, we want to hear from you.

This role offers the opportunity to build a marketplace using the latest technologies, with the chance to shape the next generation way of working. If you’re excited by the prospect of working in a fast-paced, innovative environment, collaborating with a talented team, and making a direct impact, this is the opportunity for you! 🤩

Your day-to-day as a FullStack Developer:

• Service & API Development: Architect, build and maintain scalable, reliable backend services in Node.js (e.g. NestJS) and server-side applications with Next.js.
• Microservices & Event-Driven Systems: Design and implement microservices architectures and event-driven pipelines (Kafka or similar), ensuring loose coupling, high performance, and resilience.
• Frontend Collaboration: Partner with UI/UX designers to build responsive, high-quality pixel-perfect frontends using React, Vue, or Angular, and integrate with our RESTful and GraphQL APIs.
• Performance & Quality: Optimize load times, bundle sizes, and user interactions.
• Agile & DevOps: Champion our “Shakers Agile” methodology—own your GitLab workflow, write tests, enforce CI/CD best practices, and automate where it makes sense (AWS EC2/S3/CloudFront/Lambda).
• Architecture & Quality: Apply Hexagonal Architecture, Domain-Driven Design (DDD), Clean Code, and SOLID principles to ensure a maintainable codebase.
• Security & Compliance: Implement authentication/authorization (JWT, OAuth), enforce data protection, and integrate code-quality/security tools (SonarQube).

You´re a great fit if you have this...

• Experience: At least 2 or 3 years of professional development experience—we’re looking for real, on-the-job product work, not internships or bootcamps. Bonus if you’ve shipped features at another product-focused company.

• Education: Bachelor’s degree in Computer Science, Telecommunications Engineering, Mathematics or a closely related STEM field.

• Technical Expertise: Real experience building full stack applications with Node.js, Next.js, Vue/Angular, or similar. We also accept
  • Proven experience designing RESTful APIs, microservices, and event-driven systems (Kafka).
  • Hands-on with Hexagonal Architecture, DDD, SOLID, and Clean Code practices.
  • Familiarity with AWS services (EC2, S3, CloudFront, Lambda).
• Quality & Security Mindset:
  • Strong understanding of web security best practices (authentication, authorization, data encryption).
  • Experience with quality and security tooling (JWT, OAuth, SonarQube, Kiuwan).
• Startup & Collaboration:
  • Highly proactive—more than just executing specs, you’ll propose improvements, optimize performance, and drive scalability.
  • Excellent communicator and team player, comfortable working in a lean, agile environment.
  • Results-oriented, self-managed, and adaptable to shifting priorities.
• Passion & Fit:
  • A genuine love for coding and continuous learning.
  • Comfort in a fast-paced, high-traction startup culture.
  • A mindset of ownership—you take pride in delivering rock-solid, user-focused products.
