Responsibilities
•Designing, building, and maintaining core Python infrastructure libraries and frameworks used across engineering teams
•Developing and supporting high-scale microservices and the shared foundations they run on
•Building reusable infrastructure capabilities for data access, messaging, observability, and service communication
•Driving engineering standards around performance, observability, security, maintainability, and production readiness
•Driving CI/CD processes, deployment automation, and cloud-native operational practices
•Addressing performance, concurrency, and scalability challenges across mission-critical Python services
•Handling data and infrastructure challenges across PostgreSQL, MongoDB, OpenSearch, Redis, Kafka, and SQS
•Diagnosing production issues that require deep understanding of runtime behavior, such as memory, CPU, I/O, and process and thread behavior
•Managing the growing complexity of modern software ecosystems by building infrastructure that guides developers toward best practices while preserving flexibility where needed
•Bridging architectural and operational gaps between Backend, DevOps, SRE, and Product Engineering teams
•Enabling faster product development through strong infrastructure libraries and foundations
•Ensuring stable, scalable, and efficient production systems across critical platform components
•Improving developer experience through well-designed, reusable components and streamlined engineering workflows
•Driving the long-term evolution of Gong's Python infrastructure and engineering standards
Requirements
•5+ years of experience building large-scale backend systems in production environments
•Strong hands-on experience with Python and modern Python service frameworks
•Experience building and maintaining shared libraries, including API design, versioning, backward compatibility, and packaging
•Deep understanding of Python's concurrency models, including threading, multiprocessing, asyncio, and the GIL, and knowledge of when to use each
•Solid understanding of operating system fundamentals, such as processes, memory, networking, and I/O, and how they affect services in production
•Hands-on experience with relational and non-relational data sources, including connection management and performance at scale
•Proven experience designing and operating microservices and event-driven architectures
•Strong experience with cloud infrastructure such as AWS, GCP, or Azure
•Understanding of how strong platform foundations balance flexibility with consistency in multi-technology environments
•Ability to independently drive technical solutions end-to-end in a fast-paced environment
•Strong collaboration skills across teams and clear communication of technical concepts
•Bachelor's degree in Computer Science, Software Engineering, or a related technical field
