Job description

We are seeking a Senior Data Scientist to develop scientifically rigorous mathematical and statistical methodologies that transform automotive sensor and test data into actionable engineering insights. The role focuses on signal analysis, anomaly detection, trend identification, correlation analysis, and the creation of reliable engineering metrics to support data-driven vehicle development and testing.

Key Responsibilities

• Analyze multivariate vehicle sensor, telemetry, and test datasets.
• Develop mathematical and statistical models for signal processing, anomaly detection, and trend analysis.
• Design algorithms for feature extraction, aggregation, correlation, and time-series analytics.
• Define methodologies for comparing test runs, vehicle configurations, and operating conditions.
• Perform time-domain and frequency-domain analysis, including spectral analysis where applicable.
• Develop derived engineering metrics, thresholds, normalization methods, and performance indicators.
• Validate analytical models against reference datasets and engineering expectations.
• Collaborate with Data Engineers to operationalize analytical calculations and pipelines.
• Document methodologies, assumptions, validation results, and scientific limitations.
• Deliver interpretable analytical outputs that support downstream AI and data-driven decision-making.

Required Skills

• Advanced Python programming with strong expertise in NumPy, Pandas, SciPy, and scientific computing.
• Strong background in applied mathematics, statistics, and numerical analysis.
• Experience with Digital Signal Processing (DSP), filtering techniques, FFT, spectral analysis, and time-series analytics.
• Expertise in multivariate analysis, anomaly detection, and outlier identification.
• Experience working with high-frequency sensor or measurement data.
• Ability to translate complex mathematical findings into actionable insights for engineering stakeholders.
• Strong experience validating and documenting analytical methodologies.

Preferred Skills

• Experience in automotive testing, vehicle dynamics, NVH (Noise, Vibration & Harshness), or durability engineering.
• Knowledge of CAN-based vehicle telemetry and sensor analysis.
• Experience with MATLAB/Simulink.
• Familiarity with automotive test cycles, validation processes, and measurement standards.
• Understanding of Machine Learning concepts, although ML model development is not the primary focus.

Qualifications

• Master's degree in Data Science, Statistics, Applied Mathematics, Physics, Engineering, Computer Science, or a related field.
• PhD is highly preferred and considered a significant advantage.
• 5+ years of experience in Data Science, Scientific Computing, Applied Analytics, or a related quantitative discipline.
• Proven experience converting complex engineering or sensor data into meaningful analytical insights.
• Good English communication and working with UK Time is a big plus.

Nice to Have

• Automotive, mobility, or industrial IoT domain experience.
• Experience working with large-scale telemetry or time-series data platforms.
• Exposure to AI-ready analytical architectures and explainable analytics solutions.(empty)
