The Role is within the Infrastructure & Platform team, focusing on scalable, high-performance systems across compute, storage, and networking, working closely with the product team to deliver infrastructure that never blinks.

• 3+ years building production-grade infrastructure at a reputable, established company with real scale
• Hands-on experience managing compute instances (e.g. EC2) and/or container orchestration (e.g. Docker, Kubernetes)
• Solid networking fundamentals — VPCs, load balancers, NAT, VPN, and network security
• Able and willing to work fully on-site, 5 days a week in NYC, San Francisco considered.
• Authorized to work in the United States

Nice To Haves

• Experience with CI/CD tools (e.g. Jenkins, GitHub Actions) and infrastructure as code (e.g. Terraform, CloudFormation)
• Familiarity with time-series databases (e.g. TimescaleDB, InfluxDB) and key-value stores (e.g. DynamoDB, Redis)
• Experience profiling and optimizing low-level system performance under high load

Responsibilities

• Write low-level, production-grade code in Rust for services that demand speed and reliability in real-time environments
• Deploy and manage compute resources and containers for custom services and integrations
• Automate scaling, load balancing, and congestion control across compute and database layers
• Build and maintain CI/CD pipelines for automated deployment, rollback, and continuous delivery
• Monitor and tune system performance across CPU, memory, I/O, and network for maximum throughput and resiliency
• Build indexing and explorer services to enable live, fast, and expressive data channels
