Requirements
  • 8+ years in backend testing or software development, with a proven track record of blending hands-on technical contribution with team mentorship or formal lead experience.
  • Demonstrated ability to write clean code and improve existing automation frameworks (e.g., Python, Kotlin, or Java) while knowing when to build new components from scratch.
  • Deep, practical experience testing cloud-native services and API architectures.
  • Expert-level SQL skills and extensive practical experience validating high-scale data environments, including analytical warehouses and NoSQL databases.
  • Proven ability to validate time-series data and complex data streams, ensuring consistency and integrity over time.
  • Strong background in requirements engineering, with the ability to analyze a feature at the design stage and ensure it is architected for testability and safety.
Responsibilities
  • Oversee and contribute to the validation and verification of the cloud-based data platform.
  • Act as a true player-coach balancing technical leadership, team mentorship, and direct individual contribution.
  • Responsible for the integrity of high-volume data pipelines and backend services.
  • Lead a small team of automation test engineers while also contributing to test case automation and executing test strategies.
  • Handle light management responsibilities such as defining roadmaps and professional development while splitting time between leadership and active technical contribution (writing test code, reviewing pull requests, and executing tests).
  • Master and directly contribute code to existing backend test frameworks; maintain, scale, and optimize these tools as cloud infrastructure evolves.
  • Translate complex clinical needs into actionable, testable verification plans; actively writing test cases to ensure full feature coverage.
  • Design and execute strategies to validate large-scale analytical data warehouses and NoSQL storage layers (e.g., BigQuery, Cassandra).
  • Verify the accuracy of complex datasets, focusing on time-series data.
  • Oversee and participate in the verification (V&V) process to ensure cloud services meet SaMD standards (ISO 13485, IEC 62304), providing automated testing evidence for regulatory compliance.
Desired Qualifications
  • Previous experience in a regulated industry (Healthcare, MedTech, or BioTech).
  • Familiarity with Risk Management (ISO 14971) as it informs test case prioritization.
  • Experience with CI/CD integration and cloud monitoring/observability tools.

Prolaio provides a cardiovascular-focused health tech platform that helps healthcare providers improve patient outcomes through real-time data analytics and continuous monitoring. It collects data from electronic health records, patient surveys, and wearable sensors to build predictive models that warn care teams about potential health issues before they become critical. Healthcare providers access the platform via a subscription, giving them real-time analytics, alerts, and evidence-based care planning tools to monitor patients and optimize treatments. The company differentiates itself by concentrating on cardiovascular care and enabling continuous learning, patient engagement, and collaboration with pharmaceutical companies and research institutions to support new therapies. The overall goal is to reduce hospital admissions and readmissions while delivering timely, data-driven care that keeps patients healthier.

Simplify's Take

What believers are saying

  • Kardigan says Prolaio speeds 2026 readouts across three late-stage cardiovascular programs.
  • The platform collects daily physiologic data from wearable sensors and clinic records.
  • Management says Prolaio improves trial efficiency and raises clinical success probability.

What critics are saying

  • Prolaio lost independence in 2025, so roles depend on Kardigan’s strategy.
  • Kardigan reported no revenue through March 31, 2026, funding everything from investors.
  • If Kardigan’s trials fail, Prolaio becomes a sunk cost with limited standalone demand.

What makes Prolaio unique

  • Prolaio combines FDA-cleared monitoring with cardiovascular analytics and real-world data.
  • Kardigan acquired Prolaio in February 2025, keeping the platform inside a therapeutics company.
  • Its platform supports smaller, faster cardiovascular trials using continuous remote monitoring.
