Development Engineer – Embedded Software / Firmware (PAGA/PAVA Systems)

Contribute to software quality MISRA C/C++, static analysis, configuration management, code reviews, development of unit and integration tests.

Collaborate with the estimation, production, commissioning and projects departments to derive requirements, and time scales for delivery of system solutions.

Mentor less experienced engineers.

Maintain older product: Defect rectification, bespoke solutions to meet customer requirements, solutions to hardware obsolescence.

What we look for?

Support the migration of legacy Echelon / CPM5000 communication and control functions to a new embedded architecture.

Analyse existing legacy behaviour and develop equivalent or improved implementations on STM32-based platforms.

Help define the migration path for LonTalk-related stack behaviour, node communications, and interoperability requirements.

Contribute to long-term removal of obsolete components and reduction of platform dependency risk.

Integrate firmware with higher-level software modules, communication stacks, diagnostics, and application functions used in PAGA / PAVA systems.

Support interaction between physical layer interfaces, node communications, and application-layer functions used for alarm, paging, routing, monitoring, and supervision.

Ensure effective transfer of amplifier and field-device fault information back to system nodes and controllers.

Audio & Life-Safety Functional Support

Support embedded functions related to 100V line audio systems, amplifier supervision, fault monitoring, and status reporting.

Develop software mechanisms for continuous system health checking, fault detection, and reporting.

Support deterministic and reliable behaviour required for critical alarm and public address functions.

Verification, Debug & Product Support

Investigate and resolve issues arising from development, manufacturing, commissioning, and field service.

Use structured testing, logging, and diagnostic methods to validate firmware performance and robustness.

Support regression testing and change control for product releases.

Cross-Functional Collaboration

Work closely with hardware engineers, project engineers, manufacturing, test, and service teams.

Support design reviews, system architecture activities, and issue resolution across the product lifecycle.

Contribute to documentation required for product introduction, controlled change, validation, and support.
