Nice to have experience includes internal tools, CMS platforms, document workflows, automation platforms, Angular, Node.js, Python, SQL, REST APIs, low-code/no-code options, and cloud deployments. Benefits include a motivated team, complex environment experience, impactful projects, competitive compensation, central Barcelona office with amenities, hybrid work with 2 days remote, flexible hours, professional development, meal vouchers, gym allowance, social events, and recreational facilities. No visa sponsorship; candidates must have legal work permit in Spain.

What you'll do

  • Build internal tools, workflows, and lightweight applications for engineering and non-engineering teams
  • Design and implement integrations between internal systems and third-party platforms
  • Work directly with stakeholders to understand processes, pain points, and business needs
  • Translate ideas and suggestions into clear technical plans and pragmatic solutions
  • Evaluate build-vs-buy tradeoffs and recommend the simplest viable approach
  • Improve or automate manual processes involving spreadsheets, approvals, documents, CMSs, email flows, and internal operations
  • Deliver end-to-end solutions across frontend, backend, integrations, and data flows when needed
  • Help define lightweight intake, scoping, and ownership practices for internal requests
  • Ensure solutions are maintainable, secure, and appropriately documented
  • Partner with the broader engineering group to align on technical standards and shared capabilities

Requirements

  • 1+ years of experience as a Software engineer
  • Strong full-stack skills and the ability to build end-to-end solutions with limited supervision
  • Experience working with APIs, integrations, and business workflows
  • Good judgment when deciding between custom development, SaaS, automation tooling, or simple manual solutions
  • Comfort working in ambiguous environments where requirements are not fully defined upfront
  • Strong communication skills with both technical and non-technical stakeholders
  • A pragmatic mindset: able to deliver useful solutions without overengineering
  • Ability to understand business processes and identify where technology can genuinely improve efficiency
  • Ownership mentality: able to move initiatives forward, identify blockers, and make progress without constant direction
