Design and implement high-performance backend services handling concurrent requests at scale
Build robust APIs and service-oriented architectures that power our agent platform
Develop systems with concurrency patterns to maximize throughput and reliability
Implement secure data handling for sensitive healthcare information with proper access controls
Work with distributed systems concepts like consensus, replication, and fault tolerance
Build resilient services that gracefully handle failures and maintain high availability
Optimize system performance through careful concurrency design and resource management
Solve complex backend challenges with simple, maintainable solutions
Implement monitoring, logging, and observability for backend services
Collaborate with platform teams to ensure integration across services
Design systems that scale horizontally while maintaining data consistency
Contribute to architectural decisions that shape our backend infrastructure

What we're looking for

4+ years of production-level experience with backend development languages
Strong experience with concurrency programming, including threads, async operations, and parallelism
Experience developing large-scale distributed systems or working with distributed architectures
Background working on SaaS platforms or with Service-Oriented Architectures
Experience with cloud platforms and container orchestration technologies
Strong understanding of security best practices and experience with systems handling sensitive data
Understanding of distributed systems concepts (consensus, replication, partitioning) without necessarily having built foundational frameworks
Experience with message queuing systems, event streaming, and async communication patterns
Knowledge of database systems, both SQL and NoSQL, and their scaling characteristics
Curiosity for elegant solutions and clean, maintainable code
Strong debugging skills for concurrent and distributed systems
Strong problem-solving abilities with focus on system reliability and performance
