Role

We’re hiring a Senior Backend Engineer to develop high-performance services in Rust. Altitude is a team at Squads building the modern USD account for global business.

Our mission is to accelerate the world's transition to stablecoin rails. We're creating financial infrastructure that bridges on-chain and traditional banking — seamless on/off ramps, native access to stablecoins and crypto assets, integrated yield opportunities, all protected by cutting-edge security that's enforced by code, not corporate promises.

Stablecoins will consume every aspect of finance. We're here to compress that timeline.

What you’ll do

You'll build the backend services powering Altitude, working with a team shipping real products to real businesses. Our stack processes millions in daily stablecoin volume, bridging traditional banking rails with blockchain networks. You'll own entire domains from architecture to production.

Sample projects:

• Real-time settlement engine reconciling on-chain and off-chain transactions
• Bulk payment APIs processing thousands of transactions per second
• Card issuing infrastructure with instant spend notifications
• DeFi yield integration abstracting complex protocols into simple APIs

What we're looking for

• 5+ years backend experience shipping and operating production services
• Strong Rust experience (or background in Go/C++ with willingness to dive into Rust)
• Proven work with gRPC & HTTP APIs, service contracts and multi-service architectures
• Proven work with GraphQL
• Solid PostgreSQL and Redis skills - schema design, performance tuning, debugging
• AWS (ECS) and Docker expertise - containerized services, CI/CD pipelines, Terraform
• Strong engineering fundamentals - observability, testing and benchmarking
• Fintech or transaction-heavy systems experience
