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, secure-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.
