Data Security in the Age of Decentralization
As crypto adoption accelerates, so do the challenges around data integrity, privacy, and protection. That’s why we’re expanding our security team to strengthen our data defense capabilities across platforms and protocols.
The Role: Building Smarter Data Protection Systems
We are seeking experienced professionals to lead efforts in enhancing our data security detection infrastructure. In this role, you’ll play a critical part in safeguarding sensitive information across a high-scale, globally distributed environment.
Key Responsibilities:
- Design and implement advanced data security detection mechanisms, including Data Loss Prevention (DLP), data encryption, and data masking strategies.
- Continuously evaluate and refine existing detection rules and models to improve accuracy and reduce false positives.
- Lead incident response for data security events—from identification and investigation to forensic analysis and remediation.
- Expand risk detection coverage by optimizing rule logic and integrating behavioral analytics.
- Develop comprehensive data asset maps to visualize data flows across systems.
- Apply graph-based detection techniques to trace anomalous data movements and identify potential exfiltration risks.
This is not just a monitoring role—it's an opportunity to architect proactive defenses that stay ahead of emerging threats in a fast-moving digital landscape.
What We’re Looking For
To succeed in this role, you should bring both technical depth and strategic insight into data security operations.
Required Qualifications:
- Bachelor’s or higher degree in Information Security, Network Security, or Computer Science.
- 3–5 years of hands-on experience in data security, with a focus on enterprise-grade protection frameworks.
- Solid understanding of the full data security lifecycle, including classification, protection, monitoring, and response.
- Proficiency with core data security technologies: DLP, UEBA, sensitive data discovery, encryption/decryption, and secure data sharing protocols.
- Experience managing endpoint data protection solutions, particularly on macOS and Linux environments.
- Familiarity with data threat modeling practices is highly desirable.
Preferred Skills:
- Hands-on experience with large-scale data processing tools such as Apache Flink, Hive, Spark, and ElasticSearch.
- Knowledge of graph technologies for mapping relationships and detecting anomalies in data access patterns.
- Background in security data mining, threat intelligence analysis, or behavioral analytics.
- Strong analytical mindset with excellent communication skills—able to translate complex technical findings into actionable insights.
- Awareness of regulatory standards and compliance requirements related to data privacy (e.g., GDPR, CCPA).
Why This Work Matters
In the blockchain space, where trust is earned through transparency and resilience, protecting user data isn’t just a compliance task—it’s central to maintaining confidence in the entire ecosystem. Every detection rule you optimize, every asset map you build, strengthens the foundation upon which millions rely.
