Role Description As a Software Engineer focusing on IoT Systems, your primary responsibility will be to develop and enhance software solutions capable of managing and processing large sensor data volumes. You’ll work closely with our sensor data, the sensor firmware team, and the Machine Condition Monitoring product team to make sensor data available reliably and on time. Your daily activities will involve designing, building, and maintaining robust applications using Python, Go, and/or Rust. Responsibilities - Design, develop, and maintain high-performance data-intensive applications using Go, Python and/or Rust, focusing on event-driven architectures. - Implement and optimize queue mechanisms and tools to manage high-volume data streams effectively. - Create tools so internal teams can access and better understand sensor data and how the devices perform on the field. - Collaborate with cross-functional teams to ensure seamless integration of event-driven systems within the larger application infrastructure. - Optimize data processing workflows for efficiency and reliability in handling large datasets. - Identify and resolve performance bottlenecks in data-intensive applications. Qualifications - Bachelor's degree in Engineering, Computer Science, Information Technology, or related fields. - Proven experience as a Software Developer/Software Engineer or similar role, with either Internet of Things expertise or experience with large amounts of data. - Technical proficiency with programming languages such as Go and Python and experience with event-driven architecture and queue tools like Kafka, RabbitMQ, or similar. - Proficient understanding of distributed systems, data structures, and advanced algorithms. - Good knowledge of database technologies (Postgres, Scylla, Mongo, ClickHouse, Redis). - Familiarity with security best practices in software integration. - Excellent problem-solving skills and the ability to work well under strict deadlines. - Experience in fast-paced environments and critical systems with very high SLA requirements. - Effective communication skills for collaborating with cross-functional teams and stakeholders. - Experience with project documentation and maintenance. - Advanced proficiency in English. Bonus Points - Fluent in English. - Experience with Low-Level Coding (C or C++ Firmware Development). - Experience with IoT Hardware. - Experience with cloud computing platforms (AWS, Azure, GCP). - Proficiency in data structures and algorithms. Benefits - Competitive salary and stock options. - 30 days of paid annual leave. - Education and courses stipend. - Earn a trip anywhere in the world every 4 years. - R$1.035/month for meals allowance. - Health plan with national coverage and without coparticipation. - Dental Insurance: we help you with dental treatment for a better quality of life. - Wellhub and Sports Incentive: R$300/mo extra if you practice activities.
