We are a 100% remote company, meaning we trust people to do their best work from wherever they are — with freedom, transparency, and collaboration. We value curious individuals eager to learn, grow, and be part of something purposefully built. Here, everyone has an active voice, real impact on decisions, and space to propose solutions and innovate. **Employment Model:** Individual Contractor (PJ). **Work Format:** Remote — work from anywhere. **Our Culture** ----------------- **Be so good they can't ignore you:** We solve problems at their root, deliver with quality and depth (based on data and best practices). **Care for people:** Because we are diverse and strive to build an environment that expands people’s worldviews and careers. **Customer-centric heart:** We focus on the value we help customers achieve by solving meaningful problems. **Passion for practice:** We believe in learning by doing, and that a well-executed good idea is better than a brilliant idea that never leaves the drawing board. **Wave is a movement toward digital transformation for major industries across Latin America — powered by accessible, reliable, and incredibly efficient technology, at scale.** Technology and customer needs have evolved significantly over the past decades, while many large enterprises continue operating with legacy structures and solutions. Our mission is to help these organizations become more digital and simpler, building better customer journeys — while gaining financial and operational efficiency. Today, most of our team (80%) works in technology — engineering, design, and product. We deeply value **what we do** and **how we do it**, caring for one another and fostering an environment where work has purpose and real impact. This drives us to **solve meaningful problems**, reducing inefficiencies across processes. We recognize that many of these challenges are complex, and what brought us here won’t necessarily take us forward. Therefore, we cultivate a culture of **autonomy** and **continuous learning**, where curiosity and the desire to evolve are fundamental. We believe that by fostering people’s growth — as professionals and human beings — we create a space where people feel good, challenged, and able to develop while (intra)entrepreneuring together, building a global, enduring tech business with real impact. **Join us to expand your world (and your career).**
