• Platform Innovation: Build long-term infrastructure solutions and internal tools to improve R&D efficiency and prevent recurring technical debt.
• Technical Leadership: Drive architectural decisions using telemetry data and collaborate across global teams to coordinate cross-functional engineering efforts.
  
  

Minimum Qualifications

• Experience: At least 6 years of professional experience in Backend Software Engineering, specifically building scalable distributed systems.
• Python Proficiency: Minimum of 5 years of hands-on experience developing core backend applications in Python.
• System Knowledge: Proven expertise in Linux internals, Networking, and Docker containerization.
• Problem Solving: Demonstrated track record of diagnosing and resolving low-level performance bottlenecks and complex architectural gaps in production environments.
  
  

Preferred Qualifications

• Infrastructure & Data: Hands-on experience with MongoDB, ClickHouse, Redis, and message queues like Celery or Kafka.
• Cloud Evolution: Experience with AWS or other cloud providers, particularly in migrating or scaling on-prem workloads.
• Deployment Expertise: Experience supporting customers with on-prem deployments and troubleshooting air-gapped or restricted environments.
