Power Electronics Engineer (IPS)

• Company: ePropelled
• Location: Coventry, UK
• Level: Engineer or Senior Engineer, depending on experience and
• demonstrated capability
• Reports to: Martin Palmer
• Working arrangements: ePropelled’s Coventry Office
• Status: Ready

About ePropelled

• ePropelled develops intelligent propulsion and power management
• systems for uncrewed vehicles operating in the air, on land and at sea. Its
• products combine electrical machines, power electronics and embedded control to
• deliver integrated propulsion and onboard power solutions. ePropelled’s products
• range in power from less than 1 kW to more than 20 kW with voltages from 12V up
• to 200V.

The role

We

• are looking for a Power Electronics Engineer to help develop the successor to
• ePropelled’s Intelligent Power Systems (iPS), also referred to as a Power
• Management Unit (PMU).

You

• will combine a broad grounding in electronics design with practical experience
• of power conversion circuits. The initial focus will be the next generation of
• power management electronics, with opportunities to contribute to other
• ePropelled electronics products as priorities require. You will work with colleagues
• from firmware, mechanical, quality, systems and manufacturing engineering to
• turn requirements into reliable, testable and manufacturable hardware.

The

• role spans circuit design, simulation, design calculations, PCB development,
• prototype bring-up, validation testing and support for production introduction.
• Power conversion, regulation, motor drive, sensing, protection and embedded
• control interfaces will be central to the work. We will be looking at an
• architecture that balances modularity with limited voltage scalability enabling
• creation of variants with lessened effort.

We

• will consider candidates at Engineer and Senior Engineer levels. The scope of
• technical ownership will reflect your experience. Motor control experience
• would be advantageous but is not required. Experience in uncrewed vehicles or
• aerospace is also welcome, but relevant experience from other electronics
• sectors is equally applicable.

Key responsibilities

• ·Translate product and system
• requirements into electronic circuit designs and verification test plans.
• ·Design and develop power
• conversion and power management circuits, including converter topologies selection,
• power switch selection, gate drives, sensing and protection as required by the
• agreed architecture.
• ·Develop supporting analogue,
• digital and microcontroller-based hardware, including signal conditioning,
• communications interfaces and auxiliary supplies.
• ·Select and assess components
• using calculations, simulation and datasheet analysis, packages, tolerances,
• electrical stress, losses, thermal performance, reliability, availability and
• cost.
• ·Produce schematics and PCB
• layout, directly or with layout support, paying particular attention to
• switching loops, multi-layers stack up, track current calculation, current
• paths, grounding, signal integrity and thermal management.
• ·Bring up prototypes and
• investigate circuit and system behavior using appropriate laboratory equipment
• and safe test methods.
• ·Plan and carry out tests
• covering regulation, standards , certification, efficiency, transient response,
• protection, fault conditions and temperature across the specified operating
• range.
• ·Work with firmware engineers on
• hardware-software interfaces, timing, measurements, control-loop behaviour,
• diagnostics and fault handling.
• ·Address electromagnetic
• compatibility (EMC), reliability and design-for-manufacture requirements
• throughout development, and support relevant verification and compliance
• testing.
• ·Maintain design calculations,
• review records, test reports and controlled release documentation; support
• design reviews, manufacturing introduction and investigation of product issues.
• Level of responsibility

Engineer

You will take responsibility for

• defined circuits, boards or development activities within an agreed
• architecture. You should be able to progress routine design and test work
• independently, recognise when you need support and present evidence at design reviews.
• Technical guidance will be available for unfamiliar topology choices, complex
• control or protection behaviour, and wider system trade-offs. You will be
• supported by Senior Engineers and Engineering Managers as needed.

Senior Engineer

You will jointly own

• substantial power electronics hardware or a defined subsystem from requirements
• through verification and production release. You should have evidence of
• delivering relevant hardware through development into production or operational
• use, resolving difficult design issues and making justified trade-offs between
• performance, thermal behaviour, EMC, reliability, cost and manufacturability.

You will help shape the

• architecture for your scope, lead technical reviews and risk resolution, and
• support other engineers through review and knowledge sharing. This is a
• hands-on technical role; line management is not assumed.
• Useful additional
• experience
• The following would be advantageous; candidates are not expected to
• have all of them:
• ·Three-phase generator
• interfaces, synchronous rectification, battery charging, power-source
• changeover or bidirectional conversion.
• ·Motor drives or motor control,
• including BLDC or PMSM systems, inverter integration or starter-generator
• operation.
• ·Magnetics design, digital
• control of power converters, or detailed thermal analysis.
• ·CAN or CAN FD interfaces,
• embedded C/C++, or Python and similar tools for test automation and data
• analysis.
• ·EMC troubleshooting,
• environmental testing, design failure analysis, production test development, or
• electronics for demanding mobile or industrial environments.

Requirements

Essential skills

and experience

You should be able to demonstrate

• ·Hands-on design experience in
• at least one relevant power electronics area, such as switched-mode power
• supplies, DC–DC conversion, active rectification, battery charging or inverter
• power stages. You should be able to explain your own design decisions and the
• measured behaviour of the hardware.
• ·Practical experience, bringing
• up, debugging and validating electronic hardware, with a sound grounding in
• analogue and digital circuit design.Understanding of switching devices,
• gate-drive requirements, passive components, power losses, component ratings
• and protection against electrical faults.
• ·Working understanding of
• voltage and current regulation, feedback and stability, sufficient to analyse
• and test power converter behaviour with support appropriate to your level.
• ·Experience of schematic capture
• and PCB development software tools, and an understanding of how layout affects
• switching performance, noise and temperature.
• ·Ability to use circuit
• calculations and simulation, alongside measurements, to assess a design and
• investigate discrepancies.
• ·Confidence using oscilloscopes,
• suitable voltage and current probes, programmable supplies and electronic
• loads, with an understanding of safe measurement practices on power circuits.
• ·Familiarity with
• microcontroller-based hardware and hardware–firmware integration, including
• sensing and common communications interfaces.
• ·A systematic approach to
• troubleshooting, clear technical documentation and effective collaboration
• across engineering disciplines.
• A degree in Electronic Engineering, Electrical Engineering or a
• related discipline, or equivalent practical engineering experience, is
• appropriate. Assessment will focus on relevant capability and delivery rather
• than a fixed number of years or a particular qualification route.
