As a Machine Learning Engineer, your mission is to design and deploy intelligent systems that power core product experiences.
You will transform rich data into models that drive automation, personalization, and smart decision-making at scale.
This role blends engineering and applied science, focused on building robust, adaptive ML systems that evolve continuously and make a tangible impact.
You will join the AI team, focused on ambitious, high-impact projects beyond day-to-day urgencies.
You will work across a spectrum of machine learning solutions, from traditional ML models to agentic systems.
Collaboration is key, as you will work closely with a distributed, cross-functional team of Engineers, Data Scientists, and Analysts in a culture that values open discussion, intellectual honesty, and creative problem-solving.
You will experiment with emerging techniques and architectures to push the boundaries of real-world AI capabilities.
Working remotely, autonomy is essential, but so is communication and a shared commitment to building meaningful, intelligent systems.
The ideal candidate will have the curiosity of a researcher, the mindset of a builder, and the maturity to own both problems and outcomes.
Requirements:
You must have the initiative to learn, investigate, and experiment.
You should be able to communicate and debate in both English and Portuguese.
Excellent problem-solving and communication skills are required.

You need experience in building and deploying REST APIs using frameworks like Flask, FastAPI, or Django.
Experience with containerization technologies like Docker and orchestration tools like Kubernetes is required.
A solid understanding of software engineering best practices, including version control (Git), testing, and CI/CD, is essential.
You should have experience with cloud platforms such as AWS or Google Cloud.
Benefits:
You will have the opportunity to work with a multidisciplinary team that values exploration and curiosity.
The role offers the chance to work on diverse projects, including Credit Models, LLMs agents, and more.
You will be part of an AI-first fintech company that is focused on bringing justice to the payment system in Brazil.
The company promotes a welcoming work environment that values diversity and inclusion, allowing each employee to be authentic.
You will have access to the latest technologies and best practices in machine learning and MLOps.
