Job Description

Machine Learning Engineer

CloudWalk, Inc.

• Engineer systems that anticipate and neutralize security threats before they reach infrastructure. • Design, train, and deploy machine learning models directly at the edge. • Bridge the gap between security intelligence and massive-scale data science. • Collaborate with red teamers and security engineers to turn attack data into proactive defense mechanisms.

Job Requirements

  • Build edge intelligence. Design and train machine learning models focused on anomaly detection, bot mitigation, and zero-day intrusion detection.
  • Deploy at scale. Implement and optimize inference models to run efficiently at the edge, processing massive volumes of HTTP traffic with ultra-low latency.
  • Turn attacks into data. Work closely with our offensive security engineers to understand attack vectors, simulate realistic threats, and generate high-quality datasets for model training.
  • Automate the defense. Create robust data pipelines that continuously ingest traffic logs, monitor model performance, detect concept drift, and automate retraining based on the latest threat intelligence.

Benefits

  • Fluency in Python and SQL, with deep proficiency in ML libraries like PyTorch, TensorFlow, or Scikit-Learn.
  • Experience deploying machine learning models into production, specifically dealing with high-throughput, low-latency requirements.
  • Strong understanding of web security, HTTP protocols, and common attack vectors (e.g., OWASP Top 10, L7 DDoS, credential stuffing).
  • Familiarity with edge computing platforms (Cloudflare, Fastly, AWS Edge) and CDN/WAF concepts.
  • Solid software engineering fundamentals. You code daily and can write production-ready services in Python, Rust, TypeScript, or similar languages to integrate your models with our stack.
  • Experience with cloud-based infrastructure (GCP/AWS) and managing large-scale datasets.
  • Experience with LLMs and Agents.
  • As a member of a fully remote and distributed team, you are expected to complete tasks autonomously, being highly collaborative and self-driven.
  • Ability to communicate effectively and debate complex technical concepts in both English and Portuguese.

Senior MLOps Engineer Toronto, Ontario Engineering / Full-time / Hybrid About Us Deep Genomics is at the forefront of using artificial intelligence to transform drug discovery. Our proprietary AI platform decodes the complexity of RNA biology to identify novel drug targets, mechanisms, and therapeutics inaccessible through traditional methods. With expertise spanning machine learning, bioinformatics, data science, engineering, and drug development, our multidisciplinary team in Toronto and Cambridge, MA is revolutionizing how new medicines are created. Opportunity Join us in building the future of AI-driven drug discovery as a Senior MLOps Engineer. You will own and evolve the infrastructure that powers our ML pipelines – from cloud environments and CI/CD systems to workflow orchestration and model deployment. You will work closely with ML scientists, bioinformaticians, and software engineers to keep our platform reliable, reproducible, and scalable. Ideal Candidate You are someone who enjoys keeping the infrastructure running smoothly so that scientists can focus on their research. You are comfortable working across cloud platforms, CI/CD systems, containers, and GPUs – and you take pride in making these systems reliable and easy for others to use. You have 4+ years of experience in production infrastructure or MLOps, you write solid Python, and you are curious about the ML and scientific workflows your work supports. Above all, you are a collaborative, kind team member who communicates clearly, adapts to evolving needs, and is happy to help colleagues grow their own infrastructure skills along the way. If this sounds like you, we would love to hear from you. Key Responsibilities - Maintain and improve cloud infrastructure (GCP) using Infrastructure-as-Code tools (Terraform). - Manage IAM, RBAC, and permission policies across cloud environments. - Own and evolve CI/CD pipelines (CircleCI, GitHub Actions) and ensure best practices are followed across the engineering and ML teams. - Administer and support workflow orchestration platforms (e.g., Seqera/Nextflow, Argo, Kubeflow). - Operate and configure ML experiment tracking and registry tooling (e.g., W&B, MLflow). - Build and maintain containerized environments (Docker) and manage Kubernetes clusters. - Manage GPU resources – provisioning, scheduling, and debugging hardware and driver issues. - Write and maintain Python tooling, scripts, and integrations that support ML infrastructure. - Help deploy ML models to production environments and monitor their performance.
