Senior Reaction Controls Engineer
AI Summary
Senior Controls Engineer on the reaction control team at Mainspring Energy, focusing on optimizing linear generator performance by combining physics-based models with modern control algorithms to improve reliability, efficiency, and power output.
About this role
Job Overview
Do you love thermodynamics and dynamic system control? Have you thought about thermodynamic cycles as both continuous and discrete dynamic systems? As other industries convert their thermodynamic machines to electromagnetic machines and electrify their platforms, would you like to help generate that clean electricity?
Linear generators are a new platform that take advantage of mechanically unconstrained piston motion to cleanly and efficiently oxidize a variety of environmentally friendly fuels with disparate properties (like biogas, hydrogen, and ammonia). The linear generator reaction is close to an ideal Otto cycle, so knowledge and intuition of engine control, thermodynamics, and reaction kinetics are applicable here.
Mainspring has a high-impact opportunity for a Senior Controls Engineer on our reaction control team to help optimize the system performance by incorporating physics-based models with modern control algorithms to improve reliability, prolong service intervals, and increase power and efficiency.
Responsibilities
Implement models, algorithms, and continuous-integration (MIL, SIL, PIL) tests in C++
Develop novel fuel, air, compression ratio, and cooling automation and control strategies to improve performance, reliability, and expand the capabilities of the generator to address customer needs
Design, execute, and analyze experiments using Python on virtual or real generators to realize the impact of your work on real generators
Collaborate with other controls engineers on designs and architectures
Debug sensors, actuators, and subsystems for noise and disturbances and assist in calibration, verification, and validation. Communicate algorithms with block-diagrams, pseudo-code, code, etc.
Analyze complex thermodynamic-mechatronic systems with experimental data and create representative plant models
Support reliability and manufacturing testing of systems under control
Analyze data to assess performance capabilities and inform requirements and design decisions
Support fleet generator operation to enhance reliability and performance
Qualifications
Driven and self-directed enthusiastic contributor
Excellent communicator with demonstrated collaboration across multidisciplinary teams
Multiple years of experience designing, implementing, and testing algorithms in thermodynamic machines - experience with engines is a plus
BS + 5 years relevant experience, MS + 3 years, or Ph.D. in mechanical engineering or related degree
