Video Captioning Jobs (NOW HIRING)

About Arlo:
At Arlo, we're passionate about creating innovative and reliable solutions that help people protect what matters most to them. Our team is dedicated to delivering products that exceed our customers' expectations, while always pushing the boundaries of what's possible in the world of protection technology. We believe that everyone deserves to feel safe and secure, whether they're at home or away, and we're committed to providing our customers with the peace of mind they need to live their lives without worry. Arlo's deep expertise in AI- and CV-powered analytics, cloud services, user experience, product design, and innovative wireless and RF connectivity enables the delivery of a seamless, smart security experience for Arlo users that is easy to set up and interact with every day.

• Build, train, and fine-tune computer vision models for detection, classification, tracking, re-identification, and video understanding, and improve them against real-world customer footage - night, weather, motion blur, odd camera angles, edge compute limits.
• Own our video-understanding pipeline built on vision-language models: frame selection and temporal context, prompt and output-schema design, grounding and hallucination control, multi-event reasoning, and quality tuning for captioning and scene description.
• Adapt models to our domain: SFT, LoRA/QLoRA, preference tuning, distillation into small deployable models, and knowing when a 200M-parameter specialist beats a frontier model.
• Own the data and evaluation loop - dataset curation, labeling strategy, hard-negative and failure mining, active learning, benchmark suites, and offline/online metrics that reliably predict customer-perceived quality.
• Own the embedding and retrieval stack behind video search: multimodal/video embeddings, vector index design and tuning, hybrid search and re-ranking, and natural-language queries over a user's library.
• Build agentic experiences on top of the vision stack: tool/function calling, multi-step reasoning over event history, RAG and memory, guardrails, and tracing/observability for agent runs.
• Keep production inference fast and economical - serving stack choice and tuning (vLLM/TensorRT-LLM/Triton), quantization, batching, GPU utilization, and routing between hosted foundation models and self-hosted open models against clear cost and latency targets.
• Partner with product, data, backend, and firmware/edge teams to turn ambiguous product ideas into shipped AI features, with safe rollout (canary, A/B, feature flags) and real production telemetry.
• Raise the engineering bar - architecture and design reviews, MLOps practices, documentation, and mentoring senior and mid-level engineers.

• BS in Computer Science or a related technical field with 8+ years of experience; MS/PhD in ML, CV, or a related field preferred (or equivalent practical experience).
• 8+ years building production ML/AI systems, with a track record of owning models end to end - problem framing, data, training, evaluation, deployment, iteration.
• Strong computer vision depth: detection, classification, segmentation, tracking, video understanding; you've trained and shipped CV models in a real product.
• 3+ years working with LLMs or VLMs in production - multimodal modeling, prompt and context design, fine-tuning, and evaluation.
• Strong Python + PyTorch; solid distributed systems and cloud fundamentals (AWS, Docker).
• Rigorous about evaluation and data quality - you build the benchmark before you build the model.
• Experience with embeddings and vector search at scale; multimodal or video retrieval strongly preferred.
• Experience shipping LLM agents with tool use, and pragmatic judgment about when not to use an agent.
• Working knowledge of inference optimization (serving stacks, quantization, batching, GPU performance) and cost/latency tradeoffs at scale.
• Demonstrated technical leadership without formal authority: influencing roadmaps, mentoring engineers, driving cross-team decisions.
• Bias to ship, comfort with ambiguity, strong written communication.

• Edge/on-device inference (quantization-aware training, pruning, NPU/DSP toolchains) and streaming inference.
• Video processing at scale (decoding, frame sampling, FFmpeg-class tooling).
• Audio or sensor-fusion models complementing video; privacy-preserving or on-device personalization.
• Open-source contributions to CV, serving, retrieval, or agent frameworks; consumer IoT or camera/security domain experience.
