About the role

  • Lead the software development strategy;
  • Maintain development standards and best practices;
  • Monitor the technical evolution of development teams;
  • Troubleshoot and resolve problems, facilitating developers’ day-to-day work;
  • Serve as a technical reference;
  • Track and improve engineering metrics;
  • Collaborate on the design and development of solutions for tooling, focusing on security, performance, and observability;
  • Contribute to product behavior once in production to ensure scalability, resilience, and consistency;
  • Ensure operation and product quality and the health of its indicators (monitoring and creating alerts, participating in war rooms), and oversee the product’s technical evolution, ensuring proper design and implementation of initiatives;
  • Continuously contribute ideas and proposals to enrich the initiative’s roadmap;

Requirements

  • Advanced proficiency in Apache Kafka, including internal architecture (brokers, partitions, topics, Zookeeper) and replication and fault-tolerance mechanisms. Hands-on experience configuring and optimizing Kafka clusters for high availability and throughput. Familiarity with Kafka Streams is desirable;
  • Deep mastery of JVM languages (Java, Scala, Kotlin), with the ability to tune the JVM for garbage collection optimization, heap memory management, and application profiling. Experience with tools such as JMX, VisualVM, JFR (Java Flight Recorder), and thread dump analysis;
  • Advanced knowledge of design patterns, including practical application of Gang of Four (GoF) patterns such as Singleton, Factory, Builder, Observer, Strategy, SAGA, among others. Experience applying architectural patterns like CQRS, Event Sourcing, and Domain-Driven Design (DDD) in large-scale systems;
  • Technical capability to troubleshoot complex distributed systems. Proficiency in log analysis, distributed tracing (OpenTracing, Jaeger), and performance monitoring (APM). Experience resolving latency issues, resource contention, and intermittent failures in high-load environments;
  • Experience in designing and optimizing database schemas for both SQL (PostgreSQL, MySQL, Oracle) and NoSQL (MongoDB). Ability to implement sharding, replication, and tuning of complex queries is a plus. Knowledge of caching technologies (Redis, Memcached) for performance optimization;
  • Advanced technical experience in designing and implementing microservices architectures, including service lifecycle management, inter-service communication (REST, gRPC, event-driven), and observability and tracing mechanisms. Ability to work with Service Mesh tools (Istio, Linkerd) and CI/CD pipelines for microservices;
  • Mastery of strategic DDD, with the ability to identify and define bounded contexts and establish a ubiquitous language in collaboration with stakeholders. Experience implementing context maps and integration strategies (Shared Kernel, Customer–Supplier, Anti-Corruption Layer);
  • Ability to lead the architecture and design of technology solutions aligned with business objectives. Experience defining technical and architectural roadmaps, ensuring system scalability and resilience over time. Capacity to anticipate and mitigate architectural and technical risks in large projects;
