Job description

Labhouse is a Barcelona-based startup studio building AI-powered mobile apps used by hundreds of thousands of people worldwide. Our products — including Invoice Fly and Summary AI — are designed to make everyday tasks faster, smarter, and simpler through a subscription model that puts the user first. We were founded by Andrés Bou and Horacio Martos, the duo behind SocialPoint (acquired by Take-Two Interactive), and we operate with the mindset of a product company: small teams, high ownership, and a relentless focus on building things that matter. Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below. ABOUT THE ROLE We're looking for a Staff Software Engineer to help us tackle the next stage of growth. A hands-on engineering leader with strong technical depth, the ability to move across technologies, and experience taking products from 0→1 and scaling them from 1→100. You'll work directly with the CTO and own the most complex technical challenges in the company. You can go from architecture discussions in the morning to shipping code in the afternoon and build scalable and reliable systems, and raise the bar across the engineering team. Every stage of growth creates new constraints to solve. If you're motivated by complexity, ownership and speed, you'll likely enjoy this role. ABOUT YOU ACADEMIC BACKGROUND: - Degree in Computer Science, Telecommunications Engineering, or a related technical field. TECHNICAL EXPERTISE: - Proven experience building and launching entirely new products - Creating engineering systems that allow us to move faster and scale without increasing complexity. - Hands-on experience improving app performance and reliability across millions of users. - Capable of solving the most complex technical challenges in our systems. - Experience migrating critical infrastructure and redesigning core platform services. - Experience with a range of different technologies. Today, that includes technologies such as Flutter, Dart, TypeScript, GCP, SQL, but we don't hire based on specific frameworks. We hire people who can learn quickly and figure things out. PROBLEM-SOLVING AND PRODUCT FOCUS: - Eye for detail and a product-first mindset, with a passion for creating exceptional user experiences. - Self-driven, entrepreneurial attitude with the ability to work autonomously and take ownership of projects. - You enjoy operating in ambiguity. You care about impact more than process. You're comfortable owning outcomes, not just tasks. COMMUNICATION: - Good level of spoken and written English. - Ability to collaborate effectively with cross-functional teams, including design, product, and marketing. WHAT WE OFFER: - Remote work from anywhere in Spain. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week. - Flexible working hours. - Competitive compensation - High-end equipment for your development. - Permanent contract with competitive compensation. - A young and top entrepreneurial team in a dynamic startup environment. - Opportunity to lead, grow, and take on big challenges. - Work with cutting-edge technologies, including the chance to integrate AI models into new apps.

However you identify or whatever your journey to this point, we welcome all candidates to apply for the position that inspires them. Come join us and help us build a company that everyone is proud to be part of.
