• Develop and maintain a comprehensive API strategy, including RESTful and GraphQL APIs
• Design and implement caching strategies (e.g. Redis) to optimize performance
• Architect solutions for data consistency and integrity in distributed systems, implementing patterns such as CORS and Event Sourcing
• Collaborate with cross-functional teams to gather requirements and translate them into technical specifications
• Mentor software engineers in best practices for scalable, service-oriented architectures
• Evaluate and recommend new technologies to enhance our technology stack
• Lead the adoption of container orchestration platforms (e.g., Kubernetes)
• Implement service discovery, load balancing, and circuit breaker patterns
• Implement event-driven architectures when needed using message queues (e.g., Apache Kafka, RabbitMQ)

• Strong proficiency in C#, Python, and JavaScript, with the ability to work across multiple languages
• Experience with SQL as well as both relational and NoSQL databases, including working knowledge of ORM technologies

Nice-to-haves

• Experience in implementing observability solutions (logging, monitoring, and tracing) for microservice architectures
• Experience with service mesh technologies (e.g., Istio, Linkerd) for managing microservice communication
• Knowledge of serverless architectures and Function-as-a-Service (FaaS) platforms
• Exposure to the finance industry or with financial software systems
