Here, everyone has an active voice, real impact on decisions, and the freedom to innovate. We are a fully remote startup, meaning we trust our people to deliver their best work from wherever they are — with autonomy, transparency, and collaboration. **Contract type:** 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 (grounded in 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-first mindset:** We focus on the value we can 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 — enabled 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 carry us forward. That’s why we cultivate a culture of **autonomy** and **continuous learning**, where curiosity and the desire to grow are essential. We believe that by fostering people’s growth — as professionals and human beings — we create a space where individuals feel good, challenged, and able to develop while (intra)entrepreneuring together, building a global, enduring, and impactful tech business. **Join us to expand your world (and your career).**
