The successor to the GDPR will force data scientists to become privacy engineers or risk being left behind.

The Evolving Landscape of Data Protection

When Revolut’s London office rolled out a new customer-insight dashboard, its data-science team hit a roadblock. The UK’s Data (Use and Access) Bill demanded a “privacy-by-design” audit before any model could go live. The team paused, fearing fines and a damaged reputation.

The original GDPR set a high bar for consent, breach reporting, and data minimization. However, regulators are already drafting a successor that tightens those rules. For data scientists, the news is unsettling. Their core work—collecting, cleaning, and modeling data—is now under a legal microscope.

Understanding the GDPR’s Successor

The UK’s post-Brexit reform is the most concrete sign that Europe is moving beyond the 2018 GDPR. TechCrunch reported that the government is branding the overhaul as a “new GDPR,” promising stricter cross-border data flows and tighter algorithmic transparency. The United States is watching closely, with U.S. lawmakers drafting a comprehensive privacy law that mirrors many EU provisions.

Freshfields’ technology brief warns that businesses must prepare for “layered compliance” where EU, UK, and U.S.

These parallel tracks suggest a global convergence on data rights. Companies that operate across borders will soon face a patchwork of overlapping obligations. Freshfields’ technology brief warns that businesses must prepare for “layered compliance” where EU, UK, and U.S. rules coexist.

Implications for Data Scientists and Businesses

Non-compliance carries heavy penalties. The European Data Protection Board has already levied fines exceeding €20 million on firms that ignored GDPR breach notifications. Under the successor, penalties could rise, and reputational damage may be harder to repair.

Data scientists stand at the front line of risk. A model that inadvertently reveals personal identifiers could trigger a breach. Without proper safeguards, a single misstep could cost a company millions and ruin a career.

Preparing for the Changes

Businesses are already taking steps. Several multinational firms have launched internal “privacy labs” to test algorithms against upcoming standards. These labs combine legal counsel, data engineers, and data scientists to produce audit-ready models.

For individual data scientists, continuous learning is non-negotiable. Enrolling in privacy-focused courses, such as the IAPP’s Certified Information Privacy Technologist (CIPT), can bridge the knowledge gap. Hands-on practice with tools like TensorFlow Privacy or OpenMined’s PySyft will demonstrate competence to employers.

The Future of Data Protection and Careers

The next five years will likely see a cascade of stricter privacy rules across Europe and beyond. Individual rights will dominate: users will demand clear explanations of how AI decisions affect them, and regulators will enforce those demands.

Without proper safeguards, a single misstep could cost a company millions and ruin a career.

Data scientists who master privacy engineering will find themselves in high demand. Companies will seek talent that can balance analytical power with legal safety. Roles such as “Privacy-First Data Scientist” or “AI Compliance Engineer” are already appearing on job boards.

Conversely, those who ignore the shift risk obsolescence. As algorithms become more regulated, the ability to code without considering privacy will be a liability. Staying informed—through industry newsletters, regulator updates, and peer networks—will be as important as mastering the latest machine-learning library.
