We're looking for a Staff/Senior Software Engineer to technically lead and build Runware's serverless platform. You'll be part of a small team working closely with senior leadership to bring a new product line to market.
Runware is evolving beyond model APIs into a platform where developers can deploy models and run AI workloads without managing GPUs, servers or infrastructure. You'll build the software layer that connects our proprietary high-performance sonic inference engine and turns complex infrastructure into a compelling developer experience.
Build the core systems behind Runware's serverless platform, including workload execution, routing, scheduling, isolation and scaling leveraging our inference engine
Make it simple for developers to deploy models and run AI workloads without managing GPUs, servers, queues or infrastructure through a simple SDK interface

Build observability that makes serverless workloads easy to monitor, debug and operate at scale globally
Strong experience as a Staff Engineer, Senior Software Engineer, Backend Engineer, Platform Engineer or similar
Experience building backend services, distributed systems,



developer platforms or workload orchestration systems
Comfortable working across APIs, control planes, workers, databases and observability systems
Strong engineering fundamentals in one or more backend languages ideally Go
Experience building serverless platforms, job execution systems, container platforms or compute orchestration systems
Experience with GPU-backed workloads, AI/ML inference, model serving, batch processing or high-performance compute
Familiarity with technologies such as vLLM, TensorRT, Triton, Kubernetes, Nomad or Knative
Experience improving workload performance through batching, autoscaling, model warm-up, caching, request routing or queue management
Experience with multi-tenant isolation, sandboxing, quotas, rate limits, resource accounting or usage-based billing
Benefits We're a remote-first collective, meeting in person twice a year to plan, brainstorm, celebrate wins, and enjoy some face-to-face time. Generous paid time off - vacation, sick days, public holidays
Remote-first setup - work from home anywhere we can employ you
