Ljubljana, Ljubljana, Slovenia CobbleWeb Full time €40,000 - €80,000 per year
This position is 100% remote.

  • Complex Problem Solver: You thrive on managing complexity and are adept at designing user-centric solutions that balance technical and business needs. 
  • Passionate & Committed: You take pride in your work and view it as more than just a job.  You are motivated to contribute to our mission: to democratise the development of online marketplaces like Amazon, Airbnb and Uber.
  • Effective Communicator & Team Player: You have strong communication skills, give and receive feedback well, and collaborate effectively within cross-functional teams. 

Why CobbleWeb?
  • Professional Growth: Growth at CobbleWeb is non-negotiable. Work on diverse and challenging ecommerce projects that will push your skills to new heights. Be part of a rapidly-growing team that values your input and encourages continuous learning.
  • Purpose-Driven Process: Our structured approach to product development is rooted in Agile principles and Lean methodology. Every project phase is well-planned, starting with an in-depth discovery process, which ensures clarity and productivity. 
  • Inclusive Culture: Join a diverse, multicultural team where every opinion is valued. Collaborate across disciplines to deliver exceptional solutions.

But don't take our word for it.

Check out our team's feedback and the stats don't lie either:
  • 4.5* employee rating on Glassdoor.
  • 3.5 years average employee tenure.
  • 5* client rating on Clutch.
  • 30+ marketplaces built since 2012.

Notable exits and incredible growth stories:
  • MobyPark, a parking space app, acquired by a leading Dutch parking operator.
  • SoShop, an award-winning neobank & customer loyalty network, acquired by European fuel conglomerate, AVIA.
  • FanPass, an early-stage event ticket marketplace, already generates millions of euros in revenue.
  • Nestify, an innovative property management platform, has expanded to the UK, UAE, Spain, France, Ireland, Australia and South Africa.

The online marketplace model is taking over the world:
  • $3.5 trillion: global B2C marketplace sales
  • 67%: marketplaces' share of global ecommerce 2.
  • 310 million: active users on Amazon. If they were citizens, it would be the world's 4th largest country 

Massive opportunities for growth:
  • The B2B ecommerce market is four times the size of B2C ecommerce, with only a fraction currently served by marketplace platforms.
  • Other growth areas include niche verticals, hyper-localisation, and service marketplaces.
  • Third-party integrations such as fintech, SaaS, and procurement tools are supercharging marketplaces and also driving growth.
  • Marketplaces are early adopters of advanced technology such as AI, ML, and IoT, driving both innovation and growth.

Job requirements:
  • NodeJS frameworks, e.g. Nest or Express (3+ years experience).
  • MySQL and PostgreSQL expert (3+ years experience).
  • REST APIs.
  • Docker (local and production environments).
  • Strong understanding and proven implementation of Agile methodologies.
  • Proven application of Test Driven Development within a Continuous Integration/Continuous Delivery environment.
  • Experience with test automation.
  • RabbitMQ, Redis, AWS, or ElasticSearch experience is a plus.
