Evolito''s mission is to accelerate the adoption of electric propulsion in aerospace applications in support of a net-zero world. We will help to revolutionise personal mobility and transform our towns and cities with clean, noise-free air transportation.

Evolito develops and manufactures class-leading, lightweight, high-power, and high-torque-density electric propulsion systems for a range of aerospace markets, including EVTOL, Unmanned Aerial Vehicles and General Aviation.

As well as ultra-high performance, low-weight electric motors and controllers, Evolito specialises in high integrity, bespoke battery systems for the aerospace and defence markets. The team is scaling rapidly and has ambitious growth plans over the next twelve to eighteen months.

As part of our current high-growth phase, we are looking for a Principal Power Electronics Engineer to play a pivotal technical leadership role in shaping the design, development, and delivery of high-performance inverter systems. You will act as a technical authority, mentor, and strategic contributor, driving innovation and ensuring engineering excellence across the power electronics domain.

Key responsibilities will include:

Lead and support the development of inverter power systems, including specification definition and circuit design reviewsContribute to the system safety case in accordance with ARP4754A and DO-254 standardsDesign and validate high-power inverters for aerospace environments, ensuring compliance with performance and safety requirementsPerform thermal simulations and evaluate thermal models to ensure robust thermal managementOversee PCB layout design and provide manufacturing support to ensure design integrity and manufacturabilityAssess component lifetime, define operational limits, and apply appropriate derating strategiesSupport EMC testing and contribute to the creation and maintenance of technical documentation and compliance filesSkills and experience required:Degree or equivalent in Electrical / Electronic Engineering, or a demonstrable level of relevant industrial experiencePrevious proven experience in relevant industryDemonstrated track record of engineering ability in a power electronics disciplineStrong knowledge of power electronic devices (IGBTs, MOSFETs, wideband gap devices, Capacitors, Current sensors)Previous experience of electronic component selection and characterisationExperienced in modelling, simulation and analysis of power devices for inverter systemsProficiency in power electronics design, including schematic layout, PCB layout, component selectionAbility to perform design analysis, including worst-case, tolerance, thermal, and stressProficiency with ECAD tools including Mathcad, Simulink, Schematic, PCB, Modelling, SimulationDesigning for EMC compliance and best practicesUnderstanding of Design for Test (DFT) and Design for Manufacture (DFM)Experience developing products that comply with functional safety standards (such as ARP4754A/DO254 / ISO 26262)Experience working with high voltage / high current / high-energy systems, following safe systems of workAbility to interface with customers and suppliers with the ability to present information, detail requirements and understand issuesAbility to generate documentation to a high standard for internal and external customersStrong communication skills (both written and verbal), good collaboration skills, and the ability to work effectively across teamsInstinctive problem-solving skills coupled with a sound analytical approachA ''self-starter'' attitude with the ability to thrive in a small business environmentAbility to work under pressure and manage conflict, demands and deadlinesFlexible approach to workResults-orientated, and able to deliver business valueAn interest in continuous professional development and combining experience with new or novel techniquesAbility and willingness to travel.
