**About the role**

An Embedded Java Software Developer is responsible for designing, developing, and maintaining Java‑based firmware solutions for embedded systems. This individual will work on all aspects of Java‑centric embedded firmware, focusing on the interaction between the software and hardware components of the system.

In this role, you will be involved in key phases of development, from project planning and implementation to testing and deployment, ensuring that the embedded firmware meets the performance and functional requirements of our products. You will also contribute to advancing our product offerings and supporting legacy firmware systems by providing expert‑level product knowledge.

**Key Responsibilities**

• Develop and maintain Java‑based embedded firmware solutions using Agile methodologies.
• Write and maintain Java firmware that interacts with low‑level hardware components (e.g., sensors, actuators, communication protocols).
• Participate in project planning by investigating solutions to embedded system challenges and providing accurate estimates.
• Collaborate with hardware and systems engineering teams to ensure smooth integration of firmware with embedded hardware components.
• Ensure that the embedded firmware meets timing and performance requirements.
• Use test‑driven development (TDD) methodologies to write unit and functional tests, ensuring firmware quality and reliability.
• Debug and resolve hardware/firmware interaction issues using diagnostic tools and methodologies.
• Assist in sustaining and upgrading legacy embedded firmware products, offering consultation and product expertise.
• Explore and implement new technologies and methodologies for embedded systems, including power management, memory optimization, and low‑level driver interaction.
• Maintain documentation related to embedded firmware development, processes, and troubleshooting guides.

**Requirements**

• Bachelor's degree in Computer Science, Software Engineering or Electrical Engineering
• 3-5 years of hands‑on experience in embedded systems and Java

**Although not necessary, it would be nice if you have:**

• Certifications or coursework related to embedded systems development is a plus.
• Experience with deployment of Java‑based applications on embedded systems.
• Familiarity with Java platforms designed for constrained devices.
• Experience maintaining embedded firmware across distributed devices.
• Knowledge of safety‑critical or mission‑critical embedded software development
• Strong Java programming skills. Experience in embedded Java applications preferred.
• Experience with embedded Linux or RTOS environments.
• Experience in Test‑Driven Development (TDD) and unit/functional testing for embedded systems.
• Familiarity with Java‑based memory management, garbage collection tuning, and optimization in resource‑constrained environments.
• Familiarity with ensuring that firmware meets timing and performance requirements.
• Experience with Gradle, Maven, or other Java build systems.
• Understanding of embedded system design
• Familiarity with debugging tools (e.g., JTAG, oscilloscopes) and Linux‑based diagnostic tools (e.g., dmesg, strace).
• Experience working in an Agile/Scrum development process.
• Strong written and verbal communication skills.
• Analytical and logical reasoning skills.
• Problem‑solving skills and attention to detail.
• Ability to multi‑task and stay organized in a dynamic environment.
