 &mdash; the infrastructure powering our hosted API endpoints for the latest open‑source models. This work spans distributed systems, model serving, and developer experience. You&rsquo;ll join a small, high‑impact team operating at the intersection of product, model performance, and infra, helping to define how developers interact with AI models at scale.
 
 
 
 Responsibilities
 
 
 
 <ul>
 <li>
 Design, build, and operate the Model APIs surface with focus on advanced inference capabilities: structured outputs (JSON mode, grammar-constrained generation), tool/function calling and multi-modal serving
 </li>
 <li>
 Profile and optimize TensorRT-LLM kernels, analyze CUDA kernel performance, implement custom CUDA operators, tune memory allocation patterns for maximum throughput and optimize communication patterns across multi-GPU setups
 </li>
 <li>
 Productionize performance improvements across runtimes with deep understanding of their internals: speculative decoding implementations, guided generation for structured outputs, custom scheduling and routing algorithms for high-performance serving
 </li>
 <li>
 Build comprehensive benchmarking frameworks that measure real-world performance across different model architectures, batch sizes, sequence lengths, and hardware configurations
 </li>
 <li>
 Productionize performance improvements across runtimes (e.g.TensorRT, TensorRT‑LLM): speculative decoding, quantization, batching, and KV‑cache reuse.
 </li>
 <li>
 Instrument deep observability (metrics, traces, logs) and build repeatable benchmarks to measure speed, reliability, and quality.
 </li>
 <li>
 Implement platform fundamentals: API versioning, validation, usage metering, quotas, and authentication.
 </li>
 <li>
 Collaborate closely with other teams to deliver robust, developer‑friendly model serving experiences.
 
 
 </li>
 </ul>
 
 Requirements
 
 
 
 <ul>
 <li>
 3+ years experience building and operating distributed systems or large‑scale APIs.
 </li>
 <li>
 Proven track record of owning low‑latency, reliable backend services (rate‑limiting, auth, quotas, metering, migrations).
 </li>
 <li>
 Infra instincts with performance sensibilities: profiling, tracing, capacity planning, and SLO management.
 </li>
 <li>
 Comfortable debugging complex systems, from runtime internals to GPU execution traces.
 </li>
 <li>
 Strong written communication; able to produce clear design docs and collaborate across functions.
 
 
 </li>
 </ul>
 
 Nice To Have
 
 
 
 <ul>
 <li>
 Experience with LLM runtimes (vLLM, SGLang, TensorRT‑LLM) or contributions to open-source inference engines (vLLM, TensorRT-LLM, SGLang, TGI)
 </li>
 <li>
 Knowledge of Kubernetes, service meshes, API gateways, or distributed scheduling.
 </li>
 <li>
 Background in developer‑facing infrastructure or open‑source APIs.
 </li>
 <li>
 We value infra‑leaning generalists who bring strong engineering fundamentals and curiosity. ML experience is a plus, but not required.
 
 
 </li>
 </ul>
 
 Benefits
 
 
 
 <ul>
 <li>
 Competitive compensation, including meaningful equity.
 </li>
 <li>
 100% coverage of medical, dental, and vision insurance for employee and dependents
 </li>
 <li>
 Generous PTO policy including company wide Winter Break (our offices are closed from Christmas Eve to New Year's Day!)
 </li>
 <li>
 Paid parental leave
 </li>
 <li>
 Company-facilitated 401(k)
 </li>
 <li>
 Exposure to a variety of ML startups, offering unparalleled learning and networking opportunities.
 
 
 </li>
 </ul>
