Software Architect Lead Engineer-40683

Description

General Responsibilities: The primary role of the Basic Software Architect is to develop the top level design for ECU Basic Software and map software functionality onto hardware resources. The BSW Architect must be familiar with real-time operating system (RTOS) functionality/configuration, microcontroller peripherals, serial communication, and standard powertrain devices (i.e power supply ICs, low-side drivers, high-side drivers, CAN transcievers, etc).

Basic Software emphasis is on low level driver software for powertrain control modules, including engine control modules (ECM), transmission control modules (TCM), and hybrid power inverter modules. Experience with transfer case control module (TCCM) and active suspension controllers are also a plus.

Job Responsibilities: 

This position will be required to work directly with the customer to understand requirements and present technical software solutions. The engineer will also work with Hitachi’s hardware engineering team in Farmington Hills and Japan to define the hardware/software interface. The engineer will decompose requirements into software components, define the component interfaces, and deliver software architecture specifications to the lead software designers.

The primary work location is Farmington Hills, Michigan. Frequent travel will be required to customer sites in southeast Michigan during certain program phases. Occasional interstate travel may be required, primarily to manufacturing sites in the southern United States. International travel is rare and is not generally required for this position, however the engineer shall be qualified to travel internationally if it becomes necessary.

The specific responsibilities of the Basic Software Architect shall include (but shall not be limited to) the following:

  • Parse customer requirements and develop a requirements traceability matrix. Participate in design, code, and test reviews to ensure that traceability is maintained. Collaborate with functional safety and cybersecurity engineers to cover safety and security goals
  • Develop software architecture specifications using UML notation including use case diagrams, component diagrams, class diagrams, sequence diagrams, activity diagrams, and state machine diagrams. Supplemental notation for real-time performance reqirements is also required.
  • Collaborate with hardware engineers to define the hardware/software interface in terms of microcontroller pin assignments, mixed signal processing algorithms, signal scaling/resolution/timing, and diagnostic fault condition algorithms.
  • Collaborate with the customer to define a microcontroller memory map.
  • Must be familiar with low level drivers such as ADC, PWM, GPIO, timer modules, SPI, SCI, LIN, CAN, SENT, DMA, external bus interfaces, memory management units, ECC, flash memory, etc.
  • Must be familiar with real-time operating systems (RTOS), interrupt service routines, exception handlers, task scheduling, and multi-core CPU operation.

Qualifications

  • Possess a bachelor degree in Electrical Engineering, Computer Engineering or a related technical area.
  • Be proficient in software programming languages such as assembly, C or other high level languages.
  • Be familiar with automotive component and vehicle test procedures, including environmental and EMI/EMC testing.
  • Be generally knowledgeable in the automotive development process.
  • Have a minimum of 10 years applicable experience in automotive environment.
  • Have experience with electronic control systems.
  • Have experience with design specifications and detailed software documentation.
  • Have experience with software validation test procedures.
  • Have experience with Freescale, Renesas, and Infineon Aurix microprocessors.
  • Have working knowledge of debuggers and emulation tools, CAN interface tools and other serial communication interfaces.
  • Have experience tracking and reporting design changes.
  • Have experience coordinating and facilitating several small projects or one major project.
  • Experience with ETAS calibration tools and real time OS kernels is a plus.
  • Experience interfacing with customers.
  • Must be able to travel for to Europe, US and Japan.

Additionally, the ability to work independently with minimal direction is required as are strong verbal and written communications skills. Experience with PCs and application software, such as MS Office tools and Lotus Notes are also required.
