Job Title: Data Engineer

Reports to: VP AI

Location: France - Nice

Type: Full-time

The Position

MARSS is actively investing in Machine Learning to advance our NiDAR software across several exciting domains:

• Video Classification, Detection & Tracking

• Pattern Recognition / Anomaly Detection

• Radar Tracking

• Radio Frequency Analysis

Our current focus is primarily in video, with rapid expansion planned across the other fields. As our team grows, we are looking for a talented Data Engineer to join us.

Responsibilities

The Data Engineer will lead all data engineering tasks, including:

• Ensuring all recordings exist for each component, that recorded data is complete, and that recorders are functioning correctly across all deployments

• Designing and implementing data collection pipelines in an easily accessible, structured manner (including database management for relevant data types)

• Managing data distributed across multiple sites

• Staying informed of data recording regulations by country and implementing appropriate measures

• Managing annotations through tooling, data cross-referencing, or coordinating annotation campaigns

• Extracting meaningful metadata from datasets (event periodicity, site health warnings, usage statistics, etc.)

• Supporting the preparation of data for advanced ML models covering prediction, classification, tracking, sensor fusion, and more

Requirements

• Strong proficiency in Python, Bash, Docker, and Docker Compose for building and maintaining recording systems

• Strong SQL skills for designing and managing structured data storage and building robust data pipelines

• Highly organised, with proven experience handling large-scale datasets

• Comfortable working in Linux environments (macOS experience also welcome)

• Experience with ML frameworks such as TensorFlow, Keras, or PyTorch is a plus

Education

We prefer at least bachelors degree level in a science or engineering discipline. Masters or doctorate advantageous

The Work Environment

• Pragmatic tooling: We develop primarily on Macs and Linux.

• Small, agile team: We embrace modern development practices, new ideas are always welcome, and we adopt what works best for us.

• Diverse & multicultural: A well-rounded mix of experienced engineers, sales and project managers, and talented recent graduates.

• Passionate: We genuinely love what we do.

Integration and interfacing

Our core focus is safety and security. We bring cutting-edge software to real-world hardware, no cloud abstractions here. We interface with a wide range of equipment: radar, sonar, thermal imaging, software-defined radios, and more. Our UI runs across touchscreens, tablets, phones, smart glasses, and beyond.

Challenges

This is not a routine role. We operate in mission-critical environments in high-security locations, often with limited connectivity. Your assumptions about cloud-native workflows will be regularly tested. Deadlines are real, and creative problem-solving is essential. If you thrive under those conditions, it can be an extraordinarily rewarding experience.
