Senior Electronics & Systems Engineer

Join ONI and Explore the Boundaries of Scientific Discovery!

At ONI, we are driven by a profound mission: to propel scientific discovery and combat diseases by granting everyone the ability to visualize, comprehend, and share the intricate microscopic details of life. Our revolutionary Nanoimager and Aplo Scope stand at the forefront of advancing cellular studies on a molecular level, making substantial contributions to the evolution of scientific knowledge.

We are actively seeking an enthusiastic and self-motivated Senior Electronics & Systems Engineer to join our pioneering team located in Oxford. We believe in the power of relentless curiosity and the pursuit of excellence, and we invite you to join us in shaping the future of scientific exploration and healthcare breakthroughs.

In this role you will be the go-to technical resource for electronics design, working closely with engineering, software and R&D product teams. Electronics design is at the core of the role, but we are looking for someone who enjoys working beyond the boundaries of the PCB - developing embedded firmware, integrating sensors and actuators, and understanding how electronics interact with optics, mechanics, software and the physical world.

You will have significant technical ownership across the product lifecycle, from circuit and system design through prototyping, bring-up, verification and production. You will also develop production firmware and work further up the software stack where needed to integrate, automate and test the systems you develop.

The role is ideal for an engineer who enjoys solving complex multidisciplinary problems, takes ownership of product outcomes and thrives in a collaborative, fast-paced environment.

Your role at ONI:

• Own electronics designs from concept through architecture, schematic design, PCB development, bring-up, verification and production.
• Design robust analogue and digital electronics, including power supplies, signal conditioning, sensor interfaces, communications and control electronics.

We'd expect experience in many of the following:

• Strong analogue and digital circuit design fundamentals.
• Schematic capture, PCB layout and development of multilayer PCBs.
• Power supply design, power distribution, protection and power sequencing.
• Low-noise electronics, grounding, shielding and signal integrity.
• Sensor interfacing, analogue signal conditioning, amplification, filtering and data conversion.
• Microcontrollers and embedded systems.
• Embedded C/C++, including development of robust production firmware and low-level peripheral control, interrupts, timers, DMA and real-time behaviour.
• Developing from device datasheets and MCU/SoC reference manuals rather than relying solely on high-level libraries.
• Interfaces such as SPI, I²C, UART, CAN, USB and Ethernet.
• Practical board bring-up and fault-finding using oscilloscopes, logic analysers, multimeters and hardware debuggers.
• Design for EMC, ESD, reliability, manufacturability and test.
• Taking electronics through prototype, verification, certification and production.
• Git and modern software development practices, and Python or similar for test, automation and instrumentation.
• Working effectively across electronics, firmware, mechanical, optical and higher-level software disciplines.

Additional desirable experience includes:

• Scientific instrumentation, microscopy, imaging or other precision instruments.
• Optoelectronics, including photodiodes, LEDs/lasers, optical power monitoring or camera/image-sensor interfaces.
• Precision or low-noise analogue electronics.
• Motion control, motors, encoders, piezo actuators or feedback/control systems.
• High-speed data acquisition or communications.
• Production test fixtures, calibration systems and manufacturing automation.
• System-level debugging across complex multidisciplinary systems, including electronics, firmware, optics, mechanics and software.

At ONI, we understand that a fulfilling career involves more than just challenging work - it's about enjoying a well-rounded experience. When you become a part of our team, you not only contribute to groundbreaking research but also enjoy a range of benefits designed to enhance your life both inside and outside the workplace.

As an equal opportunity employer, we prioritize fairness and respect, ensuring every team member thrives regardless of their background. But that's not all - our perks include:

• Competitive Compensation: We recognize and reward your talent. Enjoy a competitive salary that reflects your expertise and contributions, ensuring your hard work is recognized.
• 28 days of annual leave plus 8 bank holidays and 4 dedicated wellbeing days.
• Onsite Gym Facilities: Stay active and energized with our convenient onsite gym, promoting your overall health.
• Private Healthcare and Dental Coverage: Your health matters to us. Access top-notch medical and dental services, ensuring your well-being is in good hands.
• Inclusive Culture: Be a valued member of our diverse, inclusive family. Your unique perspective is celebrated here, fostering a culture of mutual respect and understanding.
• Cycle To Work Scheme: Embrace a sustainable commute with our cycle to work program, promoting eco-friendly travel and a healthy lifestyle.
• Health Assured: Your mental health is essential. Access our comprehensive mental health support services for a balanced work-life experience.
• People’s Pension: Secure your future with our pension scheme, investing in your financial well-being beyond the workplace.
• Perks at Work: Enjoy exclusive discounts and deals through our perks at work program, adding value to your everyday life.

If you are driven by innovation, eager to make a significant impact in the realm of scientific and medical research, and possess the skills and passion we are looking for, we invite you to apply and be a part of our mission to improve our understanding of the details of life.
