MarsBased careers
MarsBased is an AI-augmented software development consultancy, based in Barcelona since 2014. We combine senior engineering talent with a proven AI methodology to build complex web applications for global enterprises and high-growth startups.
Our stack is Ruby on Rails, React, Node.js & Bun, Python and Angular. Beyond development, we cover AI, product and UI/UX design, Shopify and e-commerce, cybersecurity, enterprise software, technical due diligence and rescue projects for software in trouble.
We've delivered 200+ projects for clients like Moody's, FC Barcelona, Boston Consulting Group, HP, Ford, Citadel, Rakuten and Repsol, and 12 of our clients have exited. On average, clients stay with us for 5+ years and team members for 5.2 years.
Security is built in: we're GDPR compliant, work with privacy by design, and are completing our ISO/IEC 27001 certification in Q4 2026.
We've been 100% remote since day one and have never had an office. We work with a business-first mindset and radical transparency, and we use AI where it adds measurable value, always backed by senior engineering judgment. Our handbook is public: github.com/MarsBased/handbook
