Principal Controls Engineer

As a Principal Controls Engineer supporting Vantive’s Acute Therapies portfolio, you will be a key contributor in the model-based development and verification of control algorithms for the PrisMax system. Your work will shape how the device interprets sensor inputs, controls electromechanical components, manages operating states, and supports safe, reliable therapy delivery.

This is a hands-on individual-contributor role for an engineer who can take a complex control problem from system behavior and

through algorithm design, simulation, embedded implementation, and verification. You partner with Systems, Software, Hardware, Quality, and V&V develop, verify, and document effective control solutions.

through model architecture, implementation, integration, and lifecycle changes.

· Develop and refine algorithms using MATLAB, Simulink, and Stateflow for functions involving sensors, pumps, motors, valves, alarms, and therapy-related calculations.

· Apply control theory, dynamic-system analysis, and sound engineering judgment to evaluate performance across intended operating conditions, component variation, and foreseeable faults.

· Produce model-generated code and partner with Software Engineering on interfaces, execution behavior, and integration into the device’s embedded software.

Verify Control Algorithms

· Define verification approaches for model-based algorithms, including model review, simulation, coverage analysis, interface testing, and testing of integrated software or device behavior.

· Develop and review test cases that challenge nominal, boundary, fault, and difficult-to-reproduce conditions; ensure expected results and acceptance criteria are clear.

· Lead the technical analysis of test results and discrepancies, distinguish model defects from interface or integration issues, and drive robust resolutions.

· Produce clear, traceable design and verification documentation that supports formal test execution, design reviews, and product development records.

Advance Modeling and Simulation

· Contribute to fit-for-purpose models of device components and system dynamics so control concepts can be evaluated before and alongside physical-device testing.

· Use model-in-the-loop, software-in-the-loop, and hardware-in-the-loop methods where appropriate to explore design tradeoffs, characterize performance, and expose integration risks.

· Document model assumptions, interfaces, limitations, and supporting evidence so simulation results can be interpreted and reused responsibly.

Strengthen Controls Engineering

· Lead reviews of algorithm designs and verification strategies, making tradeoffs and technical risks visible to cross-functional partners.

· Mentor engineers in model-based design, controls analysis, testability, and disciplined problem solving while remaining directly involved in critical technical work.

· Identify opportunities to improve the controls development practice by introducing reusable models, robust test techniques, and common design practices to enhance the quality and maintainability of control algorithms.

· Master’s degree or PhD in Controls, Electrical, Mechanical, Biomedical, Systems, or a related engineering discipline.

· Demonstrated experience designing and testing executable control models using MATLAB, Simulink, and Stateflow, or a closely comparable model-based development environment.

· Experience with model-generated code and its integration into real-time embedded software.

· Experience with plant modeling, physics-based simulation, and model-in-the-loop, software-in-the-loop, or hardware-in-the-loop testing.

· Ability to independently resolve complex technical problems, lead design reviews, and influence complex technical decision making when issues arise.

· Experience developing medical devices or other safety-critical products, including

traceability, risk-informed design, configuration control, and formal documentation.

· Experience modeling fluidic, thermal, electromechanical, or physiological-system behavior relevant.

Vantive is committed to supporting the needs for flexibility in the workplace. We do so through our flexible workplace policy which includes a minimum of 3 days a week onsite. This policy provides the benefits of connecting and collaborating in-person in support of our Mission.
