Job Description

We are looking for enthusiastic, hands-on engineers who are excited about building the future of aviation.

Role Overview :
As an Electrical & Electronics Integration Engineer, you will play a key role in integrating and validating avionics, battery management systems, chargers, power converters, and other critical electrical/electronic sub-systems for our eVTOL aircraft. You will be responsible for system-level integration, software-hardware co-design, communication interfaces, and testing, ensuring seamless operation across LRUs (Line Replaceable Units).

Key Responsibilities:

• Contribute to system architecture design and electrical/electronic schematics.
• Define and maintain communication interfaces (CAN, ARINC, Ethernet, UART, SPI, I2C, RS-232/485).
• Develop & maintain CAN messaging documentation (.dbc files), simulate bus networks, analyze bus loading, troubleshoot issues, and write CAPL scripts.
• Integrate & validate DC-DC converters, PDUs, BMS, chargers, and embedded devices.
• Implement and test firmware/software modules in C/C++ on embedded targets.
• Develop integration & test plans, execute HIL (Hardware-in-the-Loop) tests, and document results.
• Support HW-SW co-design by working closely with hardware & software teams.
• Conduct code reviews, unit testing, and manage source code with Git.
• Support certification-driven development (ISO 26262, DO-178).

Requirements

Tech Skills required

• 2+ years of experience in electrical/electronics systems, embedded software development/testing.
• Strong understanding of electric power interfaces (current, voltage levels, power, power quality) and communication interfaces (CAN, ARINC, Ethernet, etc)
• Hands-on experience with Embedded C/C++, debuggers (Segger J-Link, Lauterbach), and embedded targets.
• Strong software debugging & troubleshooting skills.
• Knowledge of functional safety (ISO 26262, ASIL C/D) and/or aerospace standards (DO-178B/C, DO-254).
• Familiarity with RTOS concepts and real-time embedded systems.
• Working knowledge of Python for scripting & automation.
• Experience with Git/GitHub/GitLab for version control.
• Excellent teamwork & communication skills.

Preferred Qualification

• B.Tech or B.E / BS / B.Sc, M.Sc (Electrical & Electronics or Computer Science & Engineering) with 2 to 3 years of experience.
• Exposure to power electronics (DC-DC converters, motor controllers, Li-ion battery systems).
• Experience with CAN bus network simulation tools, CAPL scripting, and HIL setups.
• Prior work in automotive or aerospace domains.
