Responsibilities

Define the architecture that connects motion control, BLDC and stepper drivers, pumps, valves, heaters, optical modules, sensors, and photonic readout

Design the topology of multiple microcontrollers and the communication buses between them (SPI, UART, RS485, CAN, USB, GPIO triggers)

Create subsystem boundaries, interface specifications, timing diagrams, and state-machine behavior

Ensure system design meets performance, reliability, manufacturability, and cost goals

Collaborate closely with electrical, firmware, mechanical, photonics, fluidics, chemistry, and manufacturing teams

Lead architecture reviews and guide critical subsystem decisions

Anticipate edge cases and design the system to behave predictably under all conditions

Maintain a unified vision for how all subsystems interact

Define sensing and feedback loops for motion, temperature, optics, and fluidics

Specify the timing and sequencing of optical reads, mechanical movements, thermal transitions, and fluidic actions

Guide PCB design to ensure alignment with firmware behavior

Evaluate tradeoffs in component selection, power systems, performance, and durability

Define high-level firmware structure, including state machines, scheduling, inter-module communication, safety logic, and calibration modes

Ensure electronics and firmware are developed according to a single cohesive architecture

Support firmware design reviews without requiring day-to-day firmware coding

Define system-level protections, detection mechanisms, and fallback modes

Contribute to system risk analysis while another team member leads regulatory documentation

Build in robustness and predictable behavior for real-world environments

Guide the evolution of the system through early prototypes, verification builds, and mass production

Define requirements for testing, calibration, and manufacturing diagnostics

Work with suppliers and manufacturing partners to protect architectural integrity during scale-up
