• Architect and optimize high-performance, high-availability cloud-native services
• Build and maintain large-scale ETL and data processing pipelines
• Design APIs, microservices, and service-to-service communication frameworks
• Develop scalable systems for processing large, streaming, and multi-tenant datasets
• Drive technical strategy and influence architecture decisions across teams
• Improve platform observability, monitoring, reliability, and operational performance
• Collaborate closely with engineering leadership, product teams, and stakeholders
• Mentor engineers and contribute to engineering standards and best practices
• Participate in system troubleshooting, root cause analysis, and performance tuning
• Create and maintain technical documentation and architectural standards

What We’re Looking For

• 10+ years of backend or platform engineering experience
• Strong experience building and operating distributed systems at scale

• Experience with containerized environments using Docker and Kubernetes
• Strong cloud experience with AWS, Azure, or GCP
• Expertise with relational and non-relational databases such as PostgreSQL, MySQL, Cassandra, or Elasticsearch
• Experience designing scalable APIs and backend services using gRPC and Protocol Buffers
• Strong programming experience with Java/Kotlin, Python, C#, or similar backend technologies
• Experience with CI/CD pipelines, automated deployments, and infrastructure automation
• Strong understanding of system design, scalability, security, and observability
• Ability to lead complex technical initiatives while collaborating across multiple teams

Nice to Have

• Experience working with large-scale data platforms or multi-tenant systems
• Familiarity with feature flags and release toggle strategies
• Experience evaluating or integrating third-party platforms and services
• Experience with service mesh technologies such as Envoy or AWS App Mesh
• Background in highly regulated or enterprise-scale environments
• Familiarity with Agile development practices

What’s Offered

• Opportunity to work on highly complex distributed systems and platform challenges
• Strong engineering culture focused on collaboration, scalability, and innovation
• High-impact role with influence on technical direction and architecture
• Growth opportunities within a fast-moving engineering organization
• Flexible and collaborative work environment
