Your mission at Mercanis

At Mercanis, we are building the Agentic AI Procurement Suite that powers the procurement of tomorrow, digital, transparent, and intelligent.

We are looking for a Backend Engineer who is excited to build modern, reliable backend services and grow their technical expertise over time. You will work closely with senior engineers, product managers, and designers to deliver features that bring real value to our customers.

This role is perfect for someone who already has hands-on backend experience and is ready to level up in a supportive engineering culture. You will gain exposure to production-scale systems, cloud services, and event-driven architecture, while learning best practices from experienced teammates.

This role can be fully remote globally with preference for EU time zones, or hybrid from our Berlin office.

Your Responsibilities on this role

  • You will build and maintain backend services using Node.js and TypeScript, contributing to a modern, event-driven platform.
  • You will write clean, well-tested, and maintainable code, collaborating with peers during code reviews and pairing sessions.
  • You will work closely with product and design to understand user needs and turn requirements into practical, scalable backend solutions.
  • You will participate in technical discussions, bringing ideas, asking questions, and helping your team move from concept to implementation.
  • You will support the delivery lifecycle, contributing to testing, debugging, and monitoring to ensure smooth releases.
  • You will learn from senior engineers, gaining experience in cloud infrastructure, system design, and performance considerations.
  • You will stay curious and experiment, exploring new tools and contributing to continuous improvement in engineering practices.

Role requirements

  • 2–4 years of professional experience as a backend or full-stack engineer, working with c and TypeScript
  • Solid understanding of backend fundamentals, including asynchronous programming, API development, and data handling
  • Experience working with databases (PostgreSQL or similar)
  • Working knowledge of unit testing and code quality practices
  • A collaborative mindset, curiosity, and willingness to ask questions and grow
  • Clear communication skills and a team-oriented attitude
  • Fluency in English, spoken and written

Nice to have:

  • Basic experience with AWS or other cloud environments
  • Exposure to event-driven systems or microservices
  • Some familiarity with frontend frameworks such as Svelte or React
  • Experience with CI/CD pipelines, Docker, or monitoring tools

Tech you will work with:

  • Backend: Node.js, NestJS, TypeScript
  • Infrastructure: AWS, serverless components
  • Data: PostgreSQL, event streaming, messaging systems
  • Tooling: GitHub, CI/CD, automated testing frameworks

Why to join us here at Mercanis?

  • You will grow quickly with support from experienced engineers who enjoy mentoring
  • You will work in a product-focused environment where your contributions matter and reach users
  • You will collaborate in a culture built on learning, ownership, and teamwork
  • You will enjoy flexible remote work, with the option to join our Berlin office
  • You will have opportunities to expand your responsibilities over time and influence how we build software

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
