• Containerize and deploy models using Docker and Kubernetes into secure, on-premise inference environments;
• Build reproducible training and inference pipelines using tools such as MLflow, Kubeflow, or similar;
• Optimize inference performance through quantization, distillation, and efficient model architectures;

• Implement monitoring and retraining workflows to detect model drift and ensure long-term performance in production.

   

👉 Technical Requirements:

• Python expertise and strong hands-on experience with ML frameworks: PyTorch, TensorFlow, Scikit-learn, Pandas, NumPy;
• Deep understanding of NLP and Generative AI, including transformer architectures (BERT, GPT, LLaMA);

• Solid MLOps experience, including Docker, Kubernetes, experiment tracking, and CI/CD for ML;
• Ability to design data pipelines for structured data (SQL, tabular) and unstructured data (text, PDFs);

• Strong algorithmic thinking with experience implementing custom logic (e.g. graph traversal, optimization, geometric or rule-based computations).

   

👉 Professional Qualifications:

• 5+ years of experience in Machine Learning Engineering with production-grade deployments;
• Proven ability to adapt ML solutions to complex, highly regulated domains (e.g. defense, supply chain, construction, engineering);

We run high-volume lead generation campaigns across France, Belgium, and Germany using Facebook ads. We need a frontend developer who has hands-on experience building landing pages that stay live and converting in hostile environments.

This is not a normal frontend role. If you've only built marketing pages on Webflow or WordPress, this isn't for you.

What you'll actually be doing:

• Building landing pages that collect leads (name, phone, email) and don't get flagged by Google Safe Browsing, Microsoft SmartScreen, or browser security extensions (Avast, Norton, Malwarebytes, McAfee)
• Implementing DOM cloaking — dynamic form rendering, field name rotation, behavioral gating so automated scanners can't easily parse the page
• Detecting when security extensions are present in the user's browser and serving cleaner page variants to avoid heuristic blocking
• Designing and maintaining cloaking systems that serve different content to crawlers/bots vs real users
• Domain rotation workflow — we burn through domains regularly. You need to be comfortable deploying to new domains fast, managing SSL, and keeping pages live
• Rapid iteration when something gets flagged — diagnosing what triggered detection and pushing fixes within hours, not days
• Working with our existing stack: HTML/CSS/JS landing pages deployed on Azure VMs with Caddy

Must-have experience:

• You've had pages flagged by Safe Browsing or browser extensions and you fixed them. Not theoretically — actually
• You understand how Google classifies pages as "deceptive" and what triggers it (UI patterns, script behavior, domain reputation, not just malware)
• You've built or worked with cloaking systems (bot vs human detection, UA/IP filtering, JS-based fingerprinting)
• You can write obfuscated/anti-analysis JavaScript that still works cleanly for real users
• You're comfortable with domain rotation and rapid redeployment infrastructure
• You can detect browser extensions (injected DOM elements, intercepted requests, timing differences) and adapt page behavior accordingly

Nice to have:

• Experience with Facebook ad landing pages specifically
• Familiarity with European lead gen (FR/BE/DE markets)
• Knowledge of Caddy, aaPanel, or CyberPanel for server management
• Experience with call tracking integrations (Dialics or similar)

T

he reality:

This work sits in a gray area. Platforms flag lead-gen pages even when the business behind them is legitimate. The job involves constant iteration — rotating domains, adjusting code, staying ahead of detection systems. If that makes you uncomfortable, no hard feelings, but this isn't the right fit.

If you've done this kind of work before, you know exactly what I'm describing. And you probably don't put it on your CV. That's fine — just show me you can do it.

To apply, answer these two questions:

1. Describe a specific time a page you built got flagged or blocked. What triggered it and what did you do?
2. How would you detect if a user has Avast or Norton's browser extension installed, and what would you change on the page?

Don't send generic proposals. If your answer is "I would check Google Search Console," this isn't the role.
