About the role

Together AI is seeking a Staff Backend Engineer to own the technical vision, architecture, and execution of the commerce platform powering Together's Cloud products. As a staff engineer on the Commerce Engineering team, you will set the engineering direction for mission-critical capabilities - including usage-based billing, payment processing, customer-facing analytics, and product entitlements - while raising the bar for the engineers around you.
This role is ideal for a seasoned engineer who can operate at multiple altitudes: driving system design and long-term architecture decisions while staying hands-on in code. You'll be the connective tissue between engineering, product, finance, and go-to-market - translating complex business requirements into durable, scalable backend primitives that directly impact revenue and customer experience. You'll be expected to define not just what we build, but how we build it well.

Deep knowledge of distributed systems tradeoffs: consistency, availability, fault tolerance, and performance at scale
Strong understanding of low-level systems concepts: multi-threading, memory management, networking, storage, and I/O

Experience with infrastructure as code (Terraform, AWS CDK, Pulumi) and mature CI/CD workflows
Experience with payment processors (e.g. Stripe) and billing systems strongly preferred
Experience with Kubernetes and containerized deployments a plus
Bachelor's or Master's degree in Computer Science, Computer Engineering, or equivalent practical experience
