Inter Tech Stack

Brazil's largest digital bank scaling fintech infrastructure and credit products

Financial Services Belo Horizonte, Minas Gerais 1,001–5,000 employees Privately Held

Inter is a 1,000–5,000-person digital bank operating across Brazil with a diversified product suite spanning deposits, credit (mortgage, payroll, corporate), investments, and insurance. The tech stack reveals a data-heavy, distributed systems operation: Python + PySpark + Airflow for analytics pipelines, Kafka + Kubernetes + Spring Boot for microservices, and DynamoDB + PostgreSQL for persistence. Active hiring skews engineering-forward (52 open roles) with acute focus on data (20 roles) and infrastructure, while projects around zero-trust architecture, distributed service APIs, and credit activation suggest internal scaling constraints—compliance, availability, and operational friction are the stated friction points.
