About the job
We are building a highly scalable media intelligence platform that processes, analyzes, and flags potentially problematic content across large volumes of video, audio, image, and text. The platform powers content safety workflows for Tether Data products, including Keet, and must operate reliably at scale across diverse languages, formats, and content types.
As a Staff ML Systems Engineer, you will own the core of this platform - from ingestion and async processing pipelines through AI/ML model integration, inference optimization, vector search, and structured report generation. This is not a research role and it is not a prompt-engineering role. It is a production engineering role where the models are one component of a larger system that you are responsible for making fast, reliable, cost-efficient, and maintainable.
You will be the senior technical owner of the media intelligence backend. That means you define the architecture, make the hard tradeoff calls, mentor other engineers, and carry responsibility for the system in production. You will work closely with engineering leadership and collaborate with ML researchers, data engineers, and product teams to deliver a platform that provides actionable, timestamped findings to human reviewers at scale.
Responsibilities
Backend Architecture & System Ownership
Design and operate scalable backend services for media ingestion, processing, and report generation - clean, well-tested, and built for horizontal scaling from day one
Own API contracts, data models, and storage patterns for media assets, processing jobs, model outputs, embeddings, and audit trails
Build high-throughput async processing pipelines for video, audio, image, and text using queues and event-driven patterns (SQS, Kafka, Pub/Sub, or equivalent)
Implement reliable asynchronous processing with retries, idempotency, dead-letter queues, backpressure handling, and graceful degradation
AI/ML Integration & Model Workflows
Integrate and optimize AI/ML inference workflows within the backend - embedding pipelines, multimodal models, OCR, speech-to-text, scene analysis, and visual classifiers
Own model-serving infrastructure: batching strategies, concurrency tuning, warmup behavior, timeout handling, autoscaling, and GPU utilization
Apply practical model optimization techniques - quantization, distillation, batching, caching, routing to smaller models where appropriate - to hit latency, throughput, and cost targets on constrained hardware
Benchmark and evaluate candidate models using domain-relevant metrics, not just standard leaderboards. Set operating thresholds using data-driven calibration methods and document the rationale
Model Serving & Performance Optimization
Optimize AI/ML inference workflows for latency, throughput, reliability, and cost across both real-time and batch-processing paths.
Work with model-serving systems such as vLLM, Triton, TGI, SageMaker, Vertex AI, or custom inference services to improve batching, concurrency, warmup behavior, timeout handling, autoscaling, and GPU utilization.
Evaluate and apply practical model optimization techniques such as quantization, model distillation, batching, caching, prompt optimization, and routing to smaller or cheaper models where appropriate.
Design and maintain vector search and indexing systems using technologies such as Pinecone, Weaviate, Qdrant, Elastic Vectors, FAISS, pgvector, or similar tools.
Build retrieval workflows that support semantic search, similarity matching, duplicate detection, media discovery, and structured metadata search.
Monitor model and system performance in production, including API latency, queue depth, processing time, model error rates, GPU utilization, confidence distributions, drift signals, and cost per processed item.Search, Indexing & Data Retrieval
Infrastructure, Reliability & Observability
Deploy and operate systems on AWS, GCP, Azure, or equivalent cloud platforms, including compute, storage, networking, queues, model-serving infrastructure, and monitoring systems.
Ensure system reliability through logging, metrics, tracing, alerting, dashboards, operational runbooks, and incident-response best practices.
Collaboration & Engineering Leadership
Mentor junior and mid-level engineers through code reviews, design discussions, and hands-on pairing
Drive architectural decisions and raise engineering quality across backend, infrastructure, and ML integration work
Translate ambiguous product requirements into clear technical deliverables with defined success criteria
