Signicat is a pioneering Pan-European Digital Identity Service Provider, supporting over 170 data sources for seamless identity verification. Trusted by governments, financial institutions, and businesses worldwide. Such as General Financing, Compensa Life, Telia, Rimi, Volvo, and many more.
The Role
We are looking for an ML Specialist to join our Computer Vision team in Madrid. You’ll focus on building scalable, secure, and production-ready ML systems, with a strong emphasis on MLOps, data engineering, and governance—rather than traditional data science.
What You’ll Work On
We’re building remote identity verification tools used by banks, governments, and major digital services.
These tools are critical in regulated environments and have become a core part of digital infrastructure since 2020, enabling secure and seamless user verification.
The Challenge
You’ll work on real-time, high-performance systems handling sensitive data under strict regulatory requirements. Our platform is built for scale, speed, and top-level security. Every technical decision is driven by trust and compliance.
What’s Ahead
In 2025, we’re upgrading major parts of the platform to improve flexibility, performance, and growth. You’ll be part of shaping architecture and product direction, working with experienced engineers across domains like video, orchestration, and data.
Key Responsibilities
- Design and maintain data pipelines for structured and unstructured data using tools such as Kafka, Spark, Beam, or Flink.
- Implement data quality, lineage, and governance to ensure GDPR compliance and auditability.
- Create and manage datasets for model training using automated or semi-automated data curation techniques.
- Develop and maintain CI/CD workflows for model packaging, testing, and deployment
- Monitor models in production and implement processes for auto-retraining and performance alerts.
- Collaborate with backend engineers to expose models through secure APIs.
- Advocate and contribute to best practices for secure, scalable, and compliant AI/ML systems.
Desired Qualifications
- 3–5 years of professional experience in machine learning, MLOps, or data engineering.
- Hands-on experience with processing multimodal and streaming data, including images, video, logs, and structured data.
- Strong knowledge of big data tools (Spark, Beam/Flink, Kafka) and cloud storage (S3, GCS).
- Familiarity with CI/CD tools and infrastructure for ML (e.g., GitHub Actions, MLflow, Kubeflow).
- Experience deploying models to Kubernetes or serverless environments on AWS or GCP
- Background in biometric systems, computer vision, or model governance is a strong plus.
- Understanding of security practices and compliance requirements in ML systems.
