Job description

Role & responsibilities

• Firmware Development & Product Implementation


• Develop, maintain, and release to production the embedded firmware for Potter Fire Safety & Suppression and nitrogen-generation products.


• Analyse existing firmware architecture, system requirements, control sequences, hardware interfaces, field issues, and common denominator to create a single platform supporting multiple variants in the product portfolio.


• Convert product, hardware, VAVE, and regulatory requirements into modular firmware designs, testable software requirements, implementation plans, and controlled releases.


• Deliver complete changes including source code, peer-review evidence, technical documentation, integration results, regression evidence, and release-ready configuration records.


• Real-Time Control, State Machines & Diagnostics


• Design deterministic control logic and state machines for compressors, motor-control interfaces, solenoid valves, pressure regulation, purge, bypass and nitrogen-generation modes, timing, sequencing, and interlocks.


• Interface with pressure, current, temperature, flow, oxygen, switch, and other analog or digital sensors; implement calibration, filtering, plausibility checks, and fault detection.


• Implement robust actuator control for relays, contactors, solenoids, alarms, indicators, displays, and other electromechanical devices through safe hardware-abstraction layers.


• Develop alarms, diagnostics, event logs, maintenance timers, fault latching, safe-state behaviour, watchdog handling, brownout recovery, and controlled power-cycle behaviour.


• Implement pressure-control, leak-monitoring, operational-counter, product-configuration, and model-specific behaviour in accordance with approved system requirements.


• Optimize memory, CPU loading, timing, boot time, response time, communication performance, and fault recovery for reliable industrial operation.


• Hardware Integration, BSP & Communications


• Develop and maintain firmware for microcontroller-based embedded controllers using Embedded C and bare-metal or RTOS architectures.


• Own board-support packages, startup code, bootloaders, device drivers, hardware-abstraction layers, interrupts, timers, ADC/DAC, GPIO, PWM, non-volatile memory, RTC, and watchdogs.


• Develop or modify interfaces such as I2C, SPI, UART, RS-485, CAN, Ethernet, USB, display/keypad connections, DIP-switch inputs, and BMS or dry-contact interfaces as applicable.


• Perform hardware-software integration, board bring-up support, peripheral debugging, signal-level diagnosis, and root-cause analysis using appropriate laboratory instruments and protocol tools.


• Cross-Functional Collaboration & Implementation


• Work closely with the Project Manager, Electrical Hardware Engineer, Industrial Controls Engineer, Mechanical Engineer, Validation team, and Potter US product and engineering stakeholders.


• Define and review firmware-hardware interfaces and implement changes required by alternate controllers, sensors, actuators, motor controls, valve sequences, or communication devices.


• Support prototype builds, system integration, verification, product-certification testing, production trials, field-issue resolution, and controlled implementation of approved changes.


• VAVE, Sustenance & Engineering Change Support


• Assess the firmware impact of cost-reduction and component-alternate proposals; identify where software configuration, reuse, or abstraction can enable common hardware and reduce variants.


• Prepare effort, schedule, technical-feasibility, validation, and risk inputs for proposed changes in coordination with the project manager and affected engineering teams.


• Ensure firmware-enabled cost-down and sustenance changes are fully implemented and released without adverse impact on product safety, performance, reliability, serviceability, or compliance.


• Verification, Quality & Risk Management


• Develop unit, integration, hardware-in-the-loop, fault-injection, and regression tests with clear traceability to system and software requirements.


• Apply coding standards, peer review, static analysis, version control, defect tracking, change control, root-cause analysis, and corrective-action practices throughout the software lifecycle.

Preferred candidate profile

• Embedded Systems, or a related discipline.


• Strong expertise in Embedded C/C++, RTOS-based firmware design and coding, Real-time and interrupt-based systems.


• Hands-on experience with Industrial device driver development, Electro-mechanical control systems, Wired communication protocols (TCP/IP, RS485, Modbus), Wireless technologies (Zigbee, BLE, LoRa, Mesh).


• Experience developing control-oriented firmware for sensors, relays, solenoid valves, compressors or motors, alarms, industrial controllers, or other electromechanical products.


• Ability to read schematics, datasheets, logic diagrams, wiring diagrams, communication protocols, system requirements, and test specifications, and to collaborate closely with hardware engineers during bring-up and fault isolation.


• Hands-on use of IDEs, compilers, JTAG/SWD debuggers, oscilloscopes, logic analysers, DMMs, serial/CAN/Ethernet tools, Git or equivalent version control, and defect-tracking systems.
