We are looking for a BSW MCU Senior Software Architect. You will join the Base Software (BSW) Architecture team of a major OEM, designing the next generation of real-time, safety-critical ECUs based on automotive microcontrollers, and owning the software architecture, interfaces, and integration strategy for Classic AUTOSAR-based ECUs across a next-generation vehicle software platform.

Engagement details:

- Location: Bengaluru, India
- Working model: Hybrid
- Start date: ASAP
- Employment type: Contractor / Permanent EoR contract

Responsibilities:

- Own scalable, modular software architecture for multi-feature MCU-based ECUs, applying SOLID principles, design patterns, and clean layering so independent features stay decoupled and reusable across platforms and variants
- Model software architecture using SysML/UML (Rhapsody), keeping full requirement-to-architecture traceability
- Define the BSW architecture and requirements for MCU-based ECUs across Classic AUTOSAR layers, MCAL, OS configuration, watchdog, diagnostics, memory, and bootloader strategies
- Architect and specify low-level drivers and hardware-near components for MCU peripherals (PWM, DIO, SPI, ADC, CAN-FD, UART, I2C, GPT, WDG, GPIO)
- Design real-time execution models, including scheduling, interrupt handling, timing budgets, and resource constraints for ASIL-rated control units
- Define ECU start-up sequences, fault-recovery mechanisms, degraded-mode strategies, and power management policies for MCU platforms
- Collaborate with hardware architects on MCU selection, memory layouts, safety mechanisms, and system partitioning
- Lead integration of BSW modules (COM, DEM, DCM, CSM, E2E, NvM, PduR, etc.)



ensuring consistency across the AUTOSAR stack
- Drive ASPICE- and ISO 26262-compliant architecture work products, including software architecture documents and requirement specifications
- Participate in cross-domain discussions to ensure seamless integration between MCU ECUs and SoC/HPC domain controllers

Qualifications:

- Proven experience designing modular, scalable software architectures — hands-on application of SOLID principles, design patterns, and clean architecture for ECUs integrating multiple features (not configuration or integration only)
- Proficiency in SysML/UML architecture modelling (Rhapsody mandatory; PREEvision a plus)
- 5+ years of experience in embedded software architecture for automotive microcontrollers
- Strong expertise in Classic AUTOSAR (BSW, RTE, MCAL) and AUTOSAR specifications
- Deep experience with automotive MCU architectures and low-level driver design
- Experience with real-time systems, task scheduling, interrupt design, and timing analysis
- Robust understanding of ISO 26262 (ASIL-B/D) for MCU-based ECUs
- Experience with requirement management tools such as IBM DOORS Next Generation (DNG)
- Solid knowledge of automotive communication protocols (CAN, LIN, Ethernet gateway basics)
- Experience working in ASPICE-aligned development environments
- Master's degree in Electrical Engineering, Computer Science, or a related field
- Excellent communication, collaboration, and problem-solving skills in a global multicultural organization
