Lead Software Quality Engineering Backend

Who Are We?

Prolaio believes that continuous learning and collaboration can make a significant difference in how heart care is administered. 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.

This is precision cardiology and we know it’s within reach.

What Will You Do?

The Overview

The Backend Software Quality Engineering Lead will oversee and actively contribute to the validation and verification of our cloud-based data platform. In this role you will act as a true player-coach—balancing technical leadership team mentorship and direct individual contribution. You will be responsible for the integrity of our high-volume data pipelines and backend services leading a small team of automation test engineers while also contributing to test case automation and executing test strategies.

This role is ideal for a technical leader who wants to guide a team and handle management responsibilities but prefers to remain an active contributor rather than stepping into a pure management role. You must be ready to quickly adopt existing automation frameworks identify opportunities for optimization and drive the requirements-gathering process to ensure clinical safety in a Software as a Medical Device (SaMD) environment.

The Specifics

• Hands-on Leadership & Mentorship: Lead coach and mentor a team of backend automation engineers by example. You will handle light management responsibilities (defining roadmaps professional development) but will split your time between leadership and active technical contribution (writing test code reviewing PRs and executing tests).
• Active Framework Evolution: Quickly master and directly contribute code to our existing backend test frameworks. You will be hands-on in maintaining scaling and optimizing these tools ensuring they remain performant as our cloud infrastructure evolves.
• Requirements Engineering: Act as a collaborative bridge between Product Engineering and Regulatory teams. You will use your experience to translate complex clinical needs into actionable testable verification plans actively writing test cases that ensure full feature coverage.
• Data & Analytics Validation: Design and execute strategies to validate large-scale analytical data warehouses and NoSQL storage layers (e.g. BigQuery Cassandra). You will be personally responsible for verifying the accuracy of complex datasets specifically focusing on the precision of time-series data.
• Regulatory Alignment: Oversee and participate in the verification (V&V) process to ensure our cloud services meet SaMD standards (e.g. ISO 13485 IEC 62304) ensuring automated testing provides the necessary evidence for regulatory compliance.

Why Prolaio?

• 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.
• Innovative Environment: You will be part of an organization doing something that’s never been done before.
• Professional 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.
• Collaborative 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.

Who You Are?

• Technical Leadership: 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. You prefer leading by example from within the code rather than managing from a distance.
• Automation Mastery: 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.
• Cloud Backend Expertise: Deep practical experience testing cloud-native services and API architectures.
• Advanced Data Proficiency: Expert-level SQL skills and extensive practical experience validating high-scale data environments including analytical warehouses and NoSQL databases.
• Temporal Data Experience: Proven ability to validate time-series data and complex data streams ensuring consistency and integrity over time.
• Requirements & Design: 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.

Additional Qualifications (Nice to Haves)

• 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.

What We Do

Prolaio is a clinical intelligence company dedicated to unlocking continuous predictive and shareable heart data to liberate patients from hospital-based reactive care and accelerate every new therapy. The company was created by cardiologists cardiovascular practitioners and data scientists specifically to address the world’s number one cause of death — cardiovascular disease. By combining scientific rigor with cutting‑edge technology Prolaio aims to transform real‑world heart data into faster discovery today and precision care for functional cures tomorrow.

Why Work With Us

Kardigan and Prolaio were both founded to challenge the status quo in cardiology. If we have any shot at radically reducing the time and cost to develop meaningful new medicines and provide better healthcare access and outcomes for patients we need to fundamentally embrace real-world data and AI-based tools in a way that is fully integrated across
