Role & Expectations
As a Software Engineer (AI Platform), you will power the reliability, performance, and cost efficiency of the entire AI platform through backend engineering.
- Design, implement, and operate backend services while also optimizing Kubernetes clusters and cloud infrastructure
- Design and build observability infrastructure (tracing, logging, metrics) to rapidly detect and resolve failures unique to AI agents
- Deliver improvements with direct business impact through inference cost and infrastructure cost optimization
- Maintain 99.9% uptime through SLI/SLO design and operations, on-call, and incident response
- Improve developer experience for in-house engineers through CI/CD pipeline construction and development environment improvements
Why You'll Love This Role
- At the intersection of Backend × Infrastructure — A new domain where you support the entire platform through the power of backend engineering.
- Platform engineering for the AI era — Go beyond traditional infrastructure / SRE to tackle AI-specific challenges: inference cost optimization, GPU management, agent tracing, and more.
- Large-scale cloud infrastructure design — Gain experience designing and operating large-scale distributed systems with Kubernetes, event-driven architectures, and autoscaling.
- Cost optimization with real impact — Inference and infrastructure cost optimization directly translates to business impact. Improving $/request ripples across all products.
- Powering every product — Support 99.9% uptime for a production environment used by ~200 companies. Every AI agent runs on the infrastructure you build.
- Rapid-growth environment — In a startup that has grown to 200+ people and 9 products in just 3 years, you will have significant autonomy in technical decision-making.
