We’re launching a brand-new project at Mediacube that rethinks how software is built. We’re embracing the Vibecode approach! Where developers orchestrate AI agents, validate ideas quickly, and turn them into real products.

This is a chance to join us at the very beginning, shape the direction of the project, and help define what the future of AI-assisted full-stack development looks like!

What are you going to do:

  • Design and build simple but very practical internal and external tools for Mediacube using the Vibecode approach
  • You work with AI agents and tools as your main dev environment, not as a side helper
  • Orchestrate AI in the full lifecycle of development. From idea and specification, through code generation and refactoring, to tests, docs, and deployment
  • Develop and maintain backend services in Ruby on Rails (high priority) Next.js or Python.
  • Let AI draft most of the code, you own the architecture, edge cases, and production quality
  • Build user friendly frontends in React or another modern framework
  • Use AI for component scaffolding, state management patterns, UX experiments
  • Integrate third party APIs and connect services so agents can collaborate and automate real work for our teams
  • Experiment with new AI agents, workflows, and tools
  • Validate hypotheses, automate processes for sales, support, operations, and turn successful experiments into stable products

You are perfect for us if you have:

First of all, about AI and your way of working

  • You work with ChatGPT, Claude or similar models every single day
  • You have shipped at least one project where most of the code was generated by AI
  • You designed the structure, wrote good prompts, reviewed and fixed the results
  • You have real experience with AI dev tools like Cursor, GitHub Copilot, or similar
  • You are not limited to “copy code into chat, paste it back into editor”
  • You are comfortable letting AI touch multiple files, refactor modules, and generate tests or docs
  • You understand LLM APIs, basic prompting patterns, and can explain how you debug AI mistakes
  • You understand how RAG, GraphRAG, and KAG work and can choose the right approach and design pipelines that leverage their strengths

Then about your dev background

  • Solid experience in software development with traditional approaches
  • You know what clean code, modular architecture, and basic testing look like
  • Confidence in at least one backend stack Node.js, Ruby, or Python
  • Hands-on experience with at least one modern frontend framework. Preferably React, but Vue or Angular are also ok
  • Experience integrating third party APIs
  • Interest or experience with MCP servers, agents, or automation platforms like n8n
  • Hackathons, pet projects, open-source, or any examples where you shipped something fast with AI help will be a big plus

What we offer:

  • You can work from anywhere in the world;
  • Medical allowance;
  • Mentorship by experienced colleagues;
  • 25 days of paid vacation;
  • 5 sick days;
  • Coworking allowance;
  • Professional training, courses and lectures;
  • English classes;
  • And much more

What Mediacube does

Mediacube helps creators manage their money comfortably, quickly, and safely. Over 10 years of work, we have built a whole ecosystem with services and apps for YouTube and Facebook authors and musicians. And at the center of this system is our own MC Pay app.

At Bending Spoons, we’re striving to build one of the all-time great companies. A company that serves a huge number of customers. A company where team members grow to their full potential. A company that functions at unparalleled levels of effectiveness and efficiency. A company that creates value for shareowners at an extraordinary rate. And a company that does so while adhering to high ethical standards.To achieve this objective, we execute the following strategy: We acquire a digital business with untapped potential and make it as successful as we can by leveraging our platform—which comprises our expertise, technologies, data, brand, talents, and company culture. Then, we invest the proceeds into making our platform more powerful, and into acquiring new businesses. Thus, our strategy sees us combine an investor’s attention to capital allocation with the hands-on approach of an operator.For a talented, driven, and collaborative individual, working at Bending Spoons is an opportunity to learn, make an impact, and progress their career at an exceptionally high rate. That’s our promise to such a candidate.

A few examples of your responsibilities

  • Power digital products with AI. Work with product teams to identify high-impact opportunities where AI can transform the user experience for millions—and then build the solutions to make them happen. Drive the process from possibility to production, delivering code that’s robust, reproducible, and built for scale.
  • Explore ways to push the boundaries of our AI capabilities. Stay at the bleeding edge of AI by investigating new models, techniques, and research. Learn fast across new domains, share findings with the team, and turn breakthrough ideas into production systems that deliver real-world impact.
  • Refine data foundations for exceptional results. Own the full data lifecycle—from acquisition and labeling to loading and management—to ensure our models are trained on clean, high-quality datasets that power top-performing systems.
  • Own your impact, end-to-end. Set smart priorities, manage execution, and consistently deliver high-quality results, even in ambiguous or fast-changing environments. Balance technical depth with strong ownership, growing your skills while delivering meaningful contributions.

What we look for

  • Reasoning ability. Given the necessary knowledge, you can solve complex problems. You think from first principles, and structure your ideas sharply. You resist the influence of biases. You identify and take care of the details that matter.
  • Drive. You’re extremely ambitious in everything you do—and your initiative, effort, and tenacity match the intensity of your ambition. You feel deeply responsible for your work. You hold yourself to a high—and rising—bar.
  • Team spirit. You give generously and without the expectation of receiving in return. You support the best idea, not your idea. You're always happy to get your hands dirty to help your team. You’re reliable, honest, and transparent.
  • Proficiency in English. You read, write, and speak proficiently in English.

What we offer

  • Incredibly talented, entrepreneurial teams. You’ll work in small, result-oriented, autonomous teams alongside some of the brightest people in your field.
  • An exceptional opportunity for growth. We go to great lengths to hire individuals of outstanding potential—then, our priority is to put them in the ideal position to thrive. Spooners in their 20s lead products worth hundreds of millions of dollars. And if you’ve got what it takes, you’ll soon be playing an essential role in major projects, too.
  • Competitive pay and access to equity in the company. Typically, we offer individuals at the start of their career an annual salary of £85,797 in London and €66,065 elsewhere in Europe. For a candidate that we assess as possessing considerable relevant experience, the salary on offer tends to be between £112,189 and £250,512 in London, and €107,837 and €188,848 elsewhere in Europe. Compensation varies by location and expected impact, and grows rapidly as you gain experience and translate it into greater contributions. For individuals who demonstrate exceptional capability, we may offer compensation that extends beyond the usual ranges to reflect their higher expected impact. If you're offered a permanent contract, you'll also be able receive some of your pay in company equity at a discounted price, thus participating in the value creation we achieve together. If relocating to Italy, you may enjoy a 50% tax cut.
  • All. These. Benefits. Flexible hours, remote working, unlimited backing for learning and training, top-of-the-market health insurance, a rich relocation package, generous parental support, and a yearly retreat to a stunning location. We help each Spooner set up the conditions to do their best work.

The selection process

If you pass our screening, we’ll ask you to take on a few tests designed to assess how you approach unfamiliar problems. They’re challenging and may take several hours to complete. If you’re successful with those, we’ll invite you to a series of interviews.  We set the bar high and won't extend an offer until we're convinced we've found the right candidate. This is why a job may stay open for months or be reposted several times.  Studies suggest that women tend not to apply for a job if their CV isn’t a perfect fit. Here, talent takes precedence over experience. So if you like the role and think you could be awesome at it in time, go ahead and apply.  Bending Spoons is an equal opportunity and affirmative action employer. We consider for employment any applicant and provide reasonable accommodations for an individual with disabilities— just let us know through this form.

Before you apply

If you’ve applied before but didn’t receive an offer, we recommend waiting at least one year before applying again.

Bending Spoons is a demanding environment. We’re extremely ambitious and we hold ourselves—and one another—to a high standard. While this tends to lead to extraordinary learning, achievement, and career growth, it also requires significant commitment.

To help you ramp up quickly and set yourself up for success, we expect you to spend most days in our Milan office during your first few months with us, regardless of your long-term work location. It’s the best way to rapidly absorb our company culture and build trust with your new teammates. We’ll support you with generous travel and accommodation assistance. After that, you’re welcome to work from one of our offices, or remotely from approved countries — depending on what we agree at the offer stage.

If the role speaks to you and you’re excited to give your best, we’d love to hear from you. Apply now — we can’t wait to meet you.
