Key Responsibilities and Required Skills for Embedded Software Developer

🎯 Role Definition

An Embedded Software Developer is responsible for designing, developing, testing, and maintaining software that runs directly on embedded hardware systems such as microcontrollers, processors, SoCs, and embedded Linux platforms. This role requires strong technical expertise in low-level programming, real-time operating systems (RTOS), and hardware–software integration. Embedded developers play a pivotal role in building reliable, high-performance firmware used in products across industries — from automotive ECUs and medical devices to consumer electronics and IoT solutions.

They collaborate with multidisciplinary teams to translate system requirements into efficient, safe, and maintainable embedded solutions that meet strict timing, resource, and compliance constraints.

Core Responsibilities

Primary Functions

Analyse system and hardware requirements, translate them into embedded software specifications and architecture.
Design, implement and maintain firmware, drivers, middleware and application logic for embedded platforms using languages such as C, C++ and assembly.
Develop and integrate software modules for microcontrollers, microprocessors, SoCs or embedded Linux systems, ensuring correct interactions with sensors, actuators and peripherals.
Collaborate with hardware engineering, electrical design and system teams to ensure seamless hardware-software integration and validate interfaces (e.g., I2C, SPI, UART, CAN, Ethernet).
Develop and maintain device drivers, board support packages (BSPs) and low-level hardware abstraction layers.
Conduct rigorous unit testing, system testing and hardware-in-the-loop (HIL) testing of embedded software to ensure functional correctness, reliability and performance.
Perform debugging, root-cause analysis of embedded systems issues — spanning software, firmware and hardware interactions (use tools such as oscilloscopes, logic analyzers, JTAG).
Optimise software for resource-constrained environments: memory usage, CPU cycles, power consumption, latency and real-time responsiveness.
Maintain and improve software development processes, including version control (e.g., Git), continuous integration/deployment (CI/CD) pipelines, code reviews and best practices.
Create, update and maintain comprehensive documentation: architecture diagrams, design specifications, test plans, user manuals, release notes.
Lead or contribute to design reviews, requirement elaboration, system level modelling and software architecture decisions to support embedded products.
Ensure compliance with industry standards and safety/risk regulations (for example automotive ISO 26262, medical IEC 62304) where applicable in embedded products.
Provide production, field and post-deployment support for embedded software — including debugging in manufacturing or in the field, firmware updates and maintenance.
Contribute to the continuous improvement of embedded system design, adopting new technologies, hardware platforms, development tools and accommodating evolving requirements.
Mentor junior engineers or team members, share knowledge of embedded best practices, review code and support skill development in the group.
Plan and execute embedded software projects: define scope, estimate tasks, track progress and report status in agile or phase-gate environments.
Participate in hardware bring-up activities: bootloader development, hardware debugging, verification of system-on-chip or microcontroller platforms.
Coordinate with cross-functional stakeholders – product management, QA/test teams, suppliers and manufacturing – to deliver embedded software aligned with product strategy.
Monitor software quality metrics, perform code reviews, enforce coding standards, static code analysis and automate testing to maintain high software integrity.
Drive innovation in embedded software architecture by suggesting optimisations for hardware resource allocation, power/thermal constraints, electronics/hardware trade-offs.

Secondary Functions

Support ad-hoc data or telemetry requests from embedded hardware, including log extraction and embedded diagnostics.
Contribute to the organisation’s embedded-systems roadmap by providing technical insight into firmware evolution, hardware migration or platform consolidation.
Collaborate with business units or product teams to translate market or functional requirements into embedded software engineering deliverables.
Participate in sprint planning, agile ceremonies (stand-ups, retrospectives) within the embedded/firmware team and interface with system engineering groups.
Assist with supply-chain or vendor firmware integration issues, including supplier code validation, firmware updates and product line maintenance.
