Software Engineer, Inference

You'll own how Luma's models get served — integrating new architectures into the inference engine, scaling deployments across thousands of machines, and keeping expensive GPU fleets busy while meeting internal SLOs. This is large-scale inference systems work: scheduling, fleet management, deployment pipelines, and reliability across clusters and hardware providers. It fits a strong systems engineer comfortable with model serving and Kubernetes  you want pure modeling rather than the systems that run models, this is firmly the systems side.

• Ship new model architectures by integrating them into the inference engine.
• Collaborate across research, engineering, and infrastructure to optimize model efficiency and deployments.
• Build internal tooling to measure, profile, and track the lifetime of inference jobs and workflows.
• Automate, test, and maintain inference services for maximum uptime and reliability.
• Manage and optimize inference workloads across clusters and hardware providers, and scale deployments across thousands of machines.
• Build scheduling systems that use expensive GPU resources optimally while meeting SLOs, and maintain CI/CD for model checkpoints and SDKs.

One way the first 90 could unfold.

• Days 1–30 — Immerse. Diagnose:
  Learn the inference stack, the fleets, and where reliability or utilization break.
• Days 30–60 — Ship. Validate:
  Integrate a model or ship tooling/scheduling that improves uptime or GPU utilization.
• Days 60–90 — Scale. Systemize:
  Harden deployment pipelines and scheduling across clusters and providers.

• Strong Python and system-architecture skills.
• Experience deploying models with PyTorch, Hugging Face, vLLM, SGLang, TensorRT-LLM, or similar.
• Experience with queues, scheduling, traffic control, and fleet management at scale.
• Experience with Linux, Docker, and Kubernetes, and with orchestration, deployment, and scheduling.
• Familiarity with Redis and S3-compatible storage.
• Nice to Have:
  Modern networking stacks including RDMA (RoCE, Infini Band, NVLink).
• High-performance large-scale ML systems (100+ GPUs).
• CUDA, and FFmpeg or multimedia processing.

Luma's mission is to build unified general intelligence that can generate, understand, and operate in the physical world. We believe multimodality is critical for intelligence — the next step beyond language models comes from vision.

Luma is an equal opportunity employer.
