Countai Private Limited is seeking a highly skilled Embedded & Controls Engineer to help develop the next generation of deployable quantum networking hardware.

You will take end-to-end ownership of the electronics and control architecture that connects our advanced photonic and quantum hardware to countai software and orchestration platforms. Your work will span custom PCB design, mixed-signal and high-speed electronics, FPGA and embedded systems, firmware, precision control algorithms, hardware APIs, and rack-level system integration.

Working closely with our photonics, software, systems, and mechanical engineering teams, you will transform laboratory prototypes into robust, manufacturable systems capable of operating outside the laboratory. You will address challenging requirements including ultra-low-noise electronics, precise synchronization, sub-nanosecond timing, high-speed signal integrity, closed-loop optical control, and reliable remote management.

Your work will establish the electronic and control infrastructure required to bring Countai private limited from research prototypes into scalable, field-deployable platforms.

You Will

- Architect custom mixed-signal PCBs for precision control, data acquisition, timing, and communication within rack-mounted quantum systems.
- Develop embedded software and firmware to control custom electronics, optical components, and photonic devices.
- Design high-speed analog and digital signal paths while maintaining stringent requirements for signal integrity, latency, synchronization, and noise.
- Interface with embedded processors, FPGAs, ADCs, DACs,



and discrete control and telemetry signals.
- Design, implement, and tune digital control loops for precision regulation and stabilization of optical and electronic hardware.
- Architect low-noise power distribution, grounding, and control electronics for sensitive quantum hardware.
- Develop interfaces for system communication using technologies such as Ethernet, UART, SPI, USB, GPIO, and high-speed data-converter interfaces.
- Define and implement APIs that enable higher-level software platforms to control hardware and access system status and telemetry.
- Develop custom cable harnessing and interconnect solutions for RF, digital, analog, telemetry, and high-speed signals.
- Collaborate with software, systems, mechanical, optical, and photonics engineers to optimize thermal performance, grounding, EMI/EMC, signal integrity, and overall system reliability.
- Lead hardware bring-up and debug complex interactions between electronics, firmware, FPGA logic, and system-level software.
- Create and implement comprehensive hardware, firmware, and system-level test plans; analyze results and drive design improvements.
- Transform laboratory and benchtop prototypes into reliable, manufacturable,



field-deployable rack-mounted systems.

Minimum Qualifications
