We deliver software solutions ranging from custom development and software implementation to data analytics and machine learning/AI integrations. As a one-stop shop, we attract clients from a variety of industries due to our proven ability to deliver cutting-edge, cost-effective software solutions.

Job Description:

We are seeking a highly skilled and motivated Embedded C/C++ Engineer to join our growing engineering team. The ideal candidate will have solid hands-on experience in embedded systems development using C and C++, with a strong emphasis on refactoring legacy code for performance, maintainability, and scalability.

As a mid-level engineer, you will contribute to both new feature development and improvement of existing firmware codebases. You should be comfortable working independently on modules as well as collaborating with cross-functional teams including hardware, QA, and product management.

Key Responsibilities:

• Design, develop, and maintain embedded software using C and C++.
• Refactor and optimize legacy code to improve performance, readability, and modularity.
• Debug firmware and hardware integration issues using tools like JTAG, oscilloscopes, and logic analyzers.
• Collaborate with senior engineers on system architecture improvements.
• Contribute to code reviews, documentation, and testing efforts.
• Ensure adherence to coding standards and best practices for embedded systems.
• Participate in sprint planning, estimation, and agile development workflows.

Requirements:

• 3–5 years of hands-on experience in embedded software development with C/C++.
• Proven experience refactoring legacy codebases in real-time or resource-constrained environments.
• Strong understanding of microcontrollers (e.g., ARM Cortex, STM32, MSP430, etc.).
• Familiarity with embedded development tools (e.g., GCC, Keil, IAR, or similar).
• Solid debugging skills using embedded development tools and techniques.
• Experience with version control (e.g., Git) and issue tracking systems (e.g., Jira).
• Excellent problem-solving, communication, and collaboration skills.

Preferred Qualifications:

• Experience with unit testing frameworks for embedded systems (e.g., Ceedling, Unity).
• Familiarity with safety-critical or regulatory-compliant development (e.g., ISO 26262, MISRA).
• Exposure to continuous integration (CI/CD) in embedded environments.
• Knowledge of low-level hardware interfacing (I2C, SPI, UART, GPIO, Client, etc.).
