Who we are
CryptoNext Security is a deeptech startup specializing in post-quantum cryptography. We help businesses and institutions prepare for a world where quantum computers will challenge today’s security standards.
Our clients include major financial institutions, defense actors, telecom operators, and global enterprises seeking to future-proof their cryptography.
On a daily basis, you will
As Senior Data & Platform Engineer, you will lead the design, setup, and operation of the entire data backbone powering COMPASS, our observability and orchestration platform for post-quantum cryptography deployments.
Your missions include:
Data Modeling & Governance
- Define and maintain the end-to-end data model for COMPASS (entities, relationships, vocabulary, lifecycle).
- Translate product requirements into robust database schemas, indexing strategies, and normalization/denormalization choices.
- Ensure semantic consistency and data governance rules across all services.
Ingestion, Streaming & Storage
- Design, validate, and maintain ingestion pipelines using Kafka, ensuring data correctness and consistency.
- Define the canonical formats exchanged across Kafka (ingestion), PostgreSQL (storage), and Elasticsearch (search).
- Validate and standardize data structures produced by probes, sensors, and backend services.
Backend Collaboration & API Contracts
- Work closely with backend teams to design API-level data contracts aligned with the data model.
- Optimize queries, indexes, and persistence strategies for real-time workloads and analytics.
Observability & Data Quality
- Contribute to platform-wide observability by defining structured logs, metadata standards, and ingestion patterns.
- Promote best practices for data quality, versioning, retention, and schema evolution.
