Signal Processing & Data Analysis Specialist (f/m/x)

We are looking for a Signal Processing & Data Analysis Specialist to join the Data Science team. In this role, you will provide technical guidance to migration, engineering, and clinical teams, ensuring a shared understanding of algorithm behavior and expected output characteristics. If you are passionate about applying your expertise in data science to validate algorithms and support system transitions, this opportunity may be the right fit for you.

Responsibilities

• Provide technical guidance on signal processing to migration, engineering, and clinical teams, ensuring a shared understanding of algorithm behavior and expected output characteristics.
• Analyze datasets to identify deviations, edge cases, and anomalies, applying appropriate statistical methods to assess the significance of discrepancies.
• Deconstruct the logic of existing signal processing algorithms and produce clear, well-structured documentation to support validation efforts and enable knowledge transfer across teams.
• Contribute to the design of validation frameworks and test cases, including defining tolerance thresholds and acceptance criteria for comparing algorithm outputs across environments.
• Develop and execute CSV-based comparison workflows to verify the consistency of algorithmic output, identifying and quantifying discrepancies.
• Collaborate with data migration specialists and engineers to resolve data-integrity issues, ensuring all deviations are properly quantified, documented, and traceable.

Requirements

• Minimum 5 years of experience with algorithm or software validation, developing data comparison or reconciliation workflows using large tabular or CSV datasets.
• PhD in Electrical Engineering, Applied Mathematics, Physics, Data Science, or a related quantitative field.
• Solid understanding of digital signal processing and time-series analysis.
• Proficiency in Python, including familiarity with libraries such as SciPy, NumPy, or pandas.
• Ability to communicate complex technical concepts to stakeholders outside your specialty.
• Advanced level of English and residency in Poland.

Nice-to-have requirements

• Familiarity with database migrations or platform equivalency testing.
• Experience with high-frequency sensor data.
