Machine Learning Systems Engineer

This is a fully remote position, open to applicants in Brazil.

📋 Description

• Design, construct, and manage scalable backend services for a media intelligence platform, emphasizing clean, maintainable, and production-ready systems.

• Take ownership of essential backend components from start to finish, covering system design and API contracts through to implementation, deployment, monitoring, and iteration.

• Influence architectural decisions related to APIs, processing pipelines, distributed computing, storage, search, observability, cloud infrastructure, and model-serving workflows.

• Create data models and storage strategies for media assets, generated metadata, embeddings, processing tasks, model outputs, search indices, and audit trails.

• Develop high-throughput media ingestion and processing pipelines capable of handling large amounts of video, audio, image, and text content.

• Construct distributed, event-driven workflows for media processing utilizing queues and pub/sub systems like SQS, Kafka, Pub/Sub, or similar technologies.

• Establish reliable asynchronous processing patterns, including retries, idempotency, dead-letter queues, backpressure management, and fault-tolerant job execution.

• Spearhead the development and enhancement of metadata extraction, content analysis, scene detection, transcription, embedding generation, and multimodal AI inference workflows.

• Collaborate with ML engineers, data scientists, or external model providers to benchmark models, assess quality/latency trade-offs, and safely implement model upgrades.

• Enhance AI/ML inference workflows for latency, throughput, reliability, and cost-effectiveness across both real-time and batch processing paths.

⛳️ Requirements

• Bachelor's degree in Computer Science, Engineering, or a related field with equivalent practical experience.

• 5-7+ years of backend engineering expertise, preferably in building scalable distributed systems, media platforms, data pipelines, or high-throughput backend services.

• Previous experience managing significant backend modules from inception to completion, including architecture, implementation, deployment, monitoring, and production operations.

• 3+ years of experience incorporating AI/ML inference systems into backend workflows, including model APIs, embedding pipelines, OCR, speech-to-text, scene detection, or multimodal model outputs.

• Practical experience in developing AI-powered processing pipelines for the analysis of images, videos, audio, or text.

• Hands-on experience with production model optimization, particularly for image, video, embedding, or multimodal models, covering batching, caching, quantization, prompt optimization, routing strategies, latency reduction, and cost efficiency.

• Previous experience with vector search, semantic search, media retrieval, or similarity-matching systems is highly preferred.

• Experience mentoring engineers, leading technical discussions, and shaping architectural decisions across backend, infrastructure, and AI/ML workflows.
