• Collaborate with stakeholders to identify problem areas and implement solutions, including frontend interfaces, data integrations, and third-party service orchestration, with a focus on reliability and resilience
• Work closely with Data Engineers, Data Scientists, and Software Engineers across the Lifecycle and Online Marketing teams

You'll be great for this position if you have:

• 3+ years of experience in full-stack software development, ideally with exposure to Go and Python
• Hands-on experience building web user interfaces using TypeScript or JavaScript, along with designing and consuming RESTful APIs in a microservice-based environment
• Experience working with SQL and event-driven architectures, including practical experience with PostgreSQL and Kafka
