Software Engineer - Infrastructure & Platform(On-Site) at Siza-Buso Consulting in New York, New York, United States

Job description

• Job Description:
• Join our Infrastructure & Platform team and take ownership of the scalable, high-performance systems that sit at the heart of our platform. You'll design and operate core components across compute, storage, and networking — working closely with our product team to deliver infrastructure that never blinks.
• This role is built for engineers who are energised by complexity, take pride in systems that perform under pressure, and want their work to matter at scale. If you come from a background in high-frequency trading, large-scale fintech, or performance-critical infrastructure — and you want to build something genuinely consequential — we want to hear from you.

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
• Provision and optimize databases across time-series, relational, key-value, and in-memory workloads

Requirements

• Rust is non-negotiable — you are a strong, practised low-level developer with Rust at your core
• 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
• Software
• 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
