## Description

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.This is a role for someone who enjoys technical leadership, hard platform problems and clean, simple systems. Your work will help enterprises, model labs and developers move from idea to production faster, then scale without needing to build and operate the infrastructure themselves.What You'll DoBuild the core systems behind Runware's serverless platform, including workload execution, routing, scheduling, isolation and scaling leveraging our inference engineMake it simple for developers to deploy models and run AI workloads without managing GPUs, servers, queues or infrastructure through a simple SDK interfaceDesign and improve the control plane for serverless execution, including APIs, workers, lifecycle management, retries and failure handlingWork closely with our infrastructure and ML teams to improve workload startup time, GPU utilisation, model warm-up, caching and placementBuild observability that makes serverless workloads easy to monitor, debug and operate at scale globallyLead the technical design, mentor other engineers and help define the engineering standards for a new product areaRequirementsStrong experience as a Staff Engineer, Senior Software Engineer, Backend Engineer, Platform Engineer or similarExperience building backend services, distributed systems, developer platforms or workload orchestration systemsStrong understanding of async processing, queues, scheduling, retries, back pressure and failure handlingComfortable working across APIs, control planes, workers, databases and observability systemsStrong engineering fundamentals in one or more backend languages ideally GoGood judgement around trade-offs between reliability, latency, scale, cost and developer experienceClear communication, strong ownership and the ability to lead technical direction in a fast-moving environmentNice to haveExperience building serverless platforms, job execution systems, container platforms or compute orchestration systemsExperience with GPU-backed workloads, AI/ML inference, model serving, batch processing or high-performance computeFamiliarity with technologies such as vLLM, TensorRT, Triton, Kubernetes, Nomad or KnativeExperience improving workload performance through batching, autoscaling, model warm-up, caching, request routing or queue managementExperience with multi-tenant isolation, sandboxing, quotas, rate limits, resource accounting or usage-based billingBenefitsWe're a remote-first collective, meeting in person twice a year to plan, brainstorm, celebrate wins, and enjoy some face-to-face time. We have core hours for cooperative working and calls, but outside of that your calendar is yours. Work the hours that let you perform at your peak while also building a healthy life.Our release cycles are fast and intense, but they're followed by real downtime. After big pushes we expect the team to unplug, recharge, and come back ready & stronger than ever for the next leap.Generous paid time off - vacation, sick days, public holidaysMeaningful stock options - share in the upside you createRemote-first setup - work from home anywhere we can employ youFlexible hours - own your schedule outside core collaboration blocksFamily leave - paid maternity, paternity, and caregiver timeCompany retreats - twice-yearly gatherings in inspiring locations#J-*****-Ljbffr
