Location: Onsite in Bloomfield, CT About LiquidPiston LiquidPiston is developing advanced rotary engines that are compact, efficient, and capable of running on multiple fuels. Our team is pioneering next-generation combustion technology used in applications from drones to generators to defense systems. We are seeking a hands-on Engine Performance Technician to support engine testing, calibration, and performance development in our state-of-the-art test facilities. Position Summary The Engine Performance Technician will work closely with engineers to execute engine tests, collect and analyze data, configure instrumentation, and support control system and calibration development. This role is ideal for individuals with strong fundamentals in internal combustion engines, test cell operation, and engine data acquisition systems. Responsibilities Set up, operate, and troubleshoot engine performance test cells for prototype and production engines. Execute test plans involving durability testing, performance mapping, emissions measurement, and transient testing. Assist with engine performance calibration, including feed-forward and closed-loop control strategies. Perform mechanical setup, fixturing, and instrumentation of engines and test rigs. Install and configure instrumentation to measure flow, temperatures, pressures, loads, and other performance-related parameters, including flow meters, thermocouples, RTDs, pressure transducers, load cells, and strain gauges. Operate and troubleshoot high-speed data acquisition systems for combustion and performance data collection. Validate sensor accuracy, wiring integrity, and signal quality. Support development and implementation of ECU communication protocols such as CAN and XCP. Assist in control software development and controller configuration. Perform PID control tuning for actuators, fuel systems, airflow systems, and thermal control systems. Use Matlab, Simulink, and Python for data analysis, test automation, and model-based development tasks. Support PLC logic development for test cell automation, interlocks, and safety systems. Requirements Understanding of internal combustion engine fundamentals, including thermodynamics, combustion, performance metrics, fueling, and air handling. Experience with engine testing, dynamometers, or engine test cell operations. Familiarity with ECU communication protocols such as CAN or XCP. Experience with Matlab, Simulink, and Python for data analysis or controls work. Ability to configure and troubleshoot engine instrumentation and high-speed data acquisition systems. Understanding of control systems and PID tuning. Ability to read wiring diagrams, assemble electrical harnesses, and diagnose electrical issues. Strong mechanical aptitude and hands-on problem-solving skills. Experience with PLC logic programming and automated test systems (preferred). Experience with model-based calibration workflows or engine control development (preferred). Experience working with prototype engines, R&D test environments, or advanced combustion systems (preferred). Knowledge of safety practices for fuel systems and rotating machinery. Benefits & Perks
