We are creating smarter ways to address heart disease and heart risks by uniting patients, care teams, and researchers on a secure, technology-enabled platform that drives clinical innovation and offers a path towards better patient outcomes.\nThis is precision cardiology, and we know it’s within reach.\nWhat Will You Do?\nThe Overview\nAs a Data Engineer in Test, you will play a critical role in advancing Prolaio’s mission to transform heart care. In this position, you will collaborate closely with cross-functional teams to validate and optimize data pipelines, ensuring the accuracy and reliability of the data infrastructure that underpins our SaMD products. Your work will be essential in delivering scalable, high-quality data systems that directly support the development of life-changing heart care solutions for patients.\nWe are looking for a highly driven individual with deep expertise in testing data pipelines, analytical workflows, and large datasets. The ideal candidate will have hands-on experience with cloud-based Data Lake environments (including services like Google Cloud Storage, BigQuery, Databricks, or Snowflake), and generating synthetic data to support testing where real patient data is limited, restricted, or unavailable. Your contributions will ensure the integrity, performance, and scalability of our data infrastructure, aligning with our commitment to delivering safe, effective, and accessible heart care solutions.\nThe Specifics\nDevelop and execute comprehensive test plans, test cases, and automated test suites for data pipelines to ensure data quality, consistency, and system performance.\nTest and validate ETL/ELT processes and data workflows across Data Lake environments, confirming the accuracy of data transformations and adherence to business logic.\nValidate data ingestion, processing, and storage within scalable cloud data platforms such as BigQuery, ensuring computed data correctly reflects raw time-series biosensor inputs.\nDesign, build, and maintain synthetic data generation tools and datasets that mimic real-world time-series biosensor data, enabling thorough test coverage where real patient data is limited or restricted.\nCollaborate with data engineers and data scientists to define testing requirements and ensure data accuracy throughout the entire data lifecycle.\nConduct performance testing and benchmarking on data systems to evaluate scalability under high data loads and identify performance bottlenecks.\nMonitor and report on key performance metrics, identifying potential data anomalies, inconsistencies, or performance issues.\nContribute to the continuous improvement of testing processes, automation frameworks, and tools used across data workflows.\nWhy Prolaio?\n Impactful Work: You will join in the fight against heart failure (HF) and hypertrophic cardiomyopathy (HCM) with the goal of extending and saving the lives of our patients while also being at the forefront of changing the healthcare industry through technology.\nInnovative Environment: You will be part of an organization doing something that’s never been done before.\nProfessional Growth: You will join a growing team and have a substantial impact on our daily and future operations with the opportunity to continuously learn and grow.\nCollaborative Team: You will be part of a team of collaborative, curious, and committed individuals focused on the collective good, inclusiveness, scientific excellence, and advancing digital health for cardiology.\nWho You Are?\nBachelor's degree in Computer Science, Data Science, or a related field.\n3+ years of experience in software testing, with a specific focus on data pipelines, Data Lake, and data warehouses.\nStrong understanding of data engineering concepts and technologies, including ETL/ELT processes, Data Lake , and cloud-based data warehouses.\nProficiency in SQL and Python for data querying, analysis, and test automation.\nExperience working with cloud-based data platforms, particularly Google Cloud Platform (GCP) and BigQuery.\nDemonstrated experience generating synthetic data for testing purposes, including designing datasets that realistically represent production data characteristics.\nFamiliarity with data testing tools and frameworks such as pytest, unittest, or TestNG.\nStrong knowledge of time-series data processing, analysis techniques, and best practices.\nExcellent problem-solving, analytical, communication, and collaboration skills.\nAdditional Qualifications (Nice to Haves)\nCertifications in data engineering or cloud platforms (e.g., GCP Certified Data Engineer, Databricks Certified Data Engineer).\nExperience in a regulated industry (Healthcare, MedTech, or BioTech), with familiarity with data governance and regulatory compliance frameworks.\nPrior experience testing systems subject to IEC 62304 or similar SaMD quality standards.\nWhy You’ll Love Working Here\nMeaningful Compensation: Competitive salary, performance bonus, and equity so you can share in what we build.\nGreat Health Coverage: Medical, dental, and vision plans with multiple options and strong company contributions.\nFlexible Spending Perks: HSA, FSA, commuter benefits, and a $1,200 annual Lifestyle Spending Account to support wellness, commuting, family needs, and more.\nTime to Recharge: Generous paid time off, sick leave, and company holidays.\nFamily-First Benefits: Paid parental leave, caregiver leave, and support for growing families.\nSecurity & Peace of Mind: Company-paid life insurance and short- and long-term disability coverage.\n Plan for the Future: 401(k) plan to help you build long-term financial security.\n Care When You Need It: Easy access to telehealth and optional supplemental coverage for life’s unexpected moments.\nStarting Salary is at $134,000.00 (Exact Compensation may vary based on skills, experience, and location)","description_format":"text","description_chars":5971,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Continuous
