Senior Firmware Engineer

Arbor Mobility; Bengaluru; On-site; INR 2,800,000 - 4,000,000; Full time

Job summary

Arbor Mobility seeks a seasoned technical lead to guide firmware teams building EV controllers (BMS/VCU/Motor Controller). You will define architecture, drive MISRA C compliance and safety practices, and ensure high-quality deliverables across design, coding, and testing.

You will mentor engineers, own the firmware strategy, and collaborate with hardware, systems, and cloud teams for end-to-end integration, while sustaining rigorous diagnostics and code reviews.

Qualifications

• BE/BTech or higher in Electronics/Electrical or related field.
• 3–5 years hands-on automotive embedded firmware experience.
• End-to-end exposure — design, development, and testing— of at least one major EV controller: BMS, VCU, or Motor Controller.
• Strong embedded C; solid grasp of microcontroller architecture, memory, interrupts, and real-time constraints.
• Practical experience with CAN / CAN-FD and automotive communication protocols.
• Working knowledge of MISRA C and ISO 26262 functional safety.
• Proficiency with embedded debugging and bench tools (JTAG/SWD, oscilloscope, logic/CAN analyzers) and version control (Git).

Responsibilities

• Lead firmware design, development, and testing for major EV controllers (BMS/VCU/Motor Controller).
• Review designs, code, and test plans to enforce MISRA C compliance and ISO 26262 practices.
• Mentor engineers; drive firmware process, reviews, and release discipline.
• Own firmware architecture and safety/diagnostics strategy (watchdogs, self-tests, fault handling).
• Collaborate with hardware, systems, and cloud/telemetry teams for end-to-end integration.
• Contribute hands-on to firmware when needed; prototype and debug critical modules.
• Maintain depth in embedded C on ARM Cortex‑M and TI C2000; RTOS/bare‑metal; CAN/SPI/UART.

Job description

Role & responsibilities

Primary Technical Leadership & Review

• Guide the firmware team through the design, development, and testing of major EV controllers (BMS, VCU, or Motor Controller / MCU), providing architecture and technical direction.
• Review designs, code, and test plans/results enforce MISRA C compliance, ISO 26262 functional-safety practices, and a high quality bar across the teams output.
• Mentor and grow engineers; drive technical decisions, coding standards, and firmware process (reviews, traceability, release discipline).
• Own the firmware architecture and the safety/diagnostics strategy — watchdogs, self-tests, plausibility checks, fault handling, and safe-state design — at the direction-setting level.
• Collaborate with hardware, systems, and cloud/telemetry teams on end-to-end integration and cross-functional decisions.

Hands-On — As Required

• Contribute directly to firmware when needed: prototyping, critical/complex modules, or unblocking the team.
• Get on the bench for tough debugging — hardware bring-up and board-level issues using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and CAN analyzers.
• Depth remains expected across embedded C on ARM Cortex-M (e.g. STM32) and/or TI C2000 (e.g. TMS320F28379x); RTOS / bare-metal architectures; and communication stacks (CAN / CAN-FD, SPI, IC, UART, ADC, PWM).

Outcomes You Own

• The team ships a controller’s firmware from design through validated, on-vehicle operation — with you steering direction and quality.
• MISRA + functional-safety + test practices are established, followed, and visible in every review.
• Fewer field/bench defects, driven by strong diagnostics, disciplined testing, and a raised review bar across the team.

Preferred candidate profile

Required Qualifications

• B.E./B.Tech/M.E./M.Tech in Electronics, Electrical, or a related field.
• 3–5 years of hands-on automotiveembedded firmware experience.
• Demonstrated end-to-end exposure — design, development, and testing— of at least one major EV controller: BMS, VCU, or Motor Controller.
• Strong embedded C; solid grasp of microcontroller architecture, memory, interrupts, and real-time constraints.
• Practical experience with CAN / CAN-FD and automotive communication protocols.
• Working knowledge of MISRA Cand ISO 26262 functional safety.
• Proficiency with embedded debugging and bench tools (JTAG/SWD, oscilloscope, logic/CAN analyzers) and version control (Git).

Preferred / Nice-to-Have

• Motor control (FOC) and power-electronics firmware experience.
• Battery systems knowledge — cell chemistry, AFE/battery-monitor ICs (ADBMS/LTC, BQ76xxx), SoC/SoH estimation, cell balancing.
• Bootloaders, OTA update, and UDS / diagnostic services.
• AUTOSAR, ASPICE, and requirements-traceability workflows.
• Python (or similar) for test automation and tooling.
• Experience with TI C2000 (TMS320F2837x) and STM32L4 families specifically.
