Your Team Your Impact

What You Can Expect

The core responsibilities for the Software team include:

• Embedded FW that runs on our RISC-V-based multi-core MCU which controls our proprietary DSP data path.

• C SDK provided to customers for interfacing and controlling our product.

• Python-based GUI for in-field debug status and control.

• Build test and automated regression infrastructure for the above.

However the Software team is a key enabler for bringing a product to production and the roll of a Software Engineer (Staff/Sr. Staff) is to work with Software/Hardware/Test teams to make that product launch a success. We work with a large and diverse cross-functional team including experts from hardware systems test customer support and operations.

In this position you will be:

• Developing in C and Python.

• The software expert on a block or portion of the design working with the rest of the team to integrate test and deliver the feature to customers.

• Responsible for the Software Architecture Design Development and Testing of embedded C firmware for this block.

• Taking lead on difficult to debug issues drive to root causes with Hardware/Systems teams and follow up with test/validation/customer support teams to make sure the issue is resolved.

• Working with the cross-functional team to plan software milestones develop in sprints closing tickets work with multiple test disciplines squash all the bugs and roll out features for the product as a whole.

• Traveling to offices worldwide for product development and chip bring-up (3weeks/yr Ottawa California Italy Vietnam).

Some possible tasks will be:

• Training an intern or new hire when they first start to give them a leg up and help integrate into the team.

• Develop python test scripts to configure control and get status from multiple DSP HW platforms for improving firmware stability.

• Breaking-up and optimizing subroutines to make the best use of a multi-core MCU architecture.

• Generating documentation examples user guides and demonstrating how to use a complicated feature to the customer support teams.

• Helping teammates to review code analyze test results and spitball ideas for how to debug a complicated customer issue.

• Implement a new temperature tracking algorithm for a DSP/analog control to improve performance when device temperature changes.

What Were Looking For

• BS/MS degree in Computer Science Electrical/Software Engineering or related technical field(s).

• 5 years of experience in memory constrained embedded C/C FW development.

• Experience with technical ownership on embedded projects; task management release planning architecture design development code reviews testing all the way through to customer volume production.

• Understanding of embedded SoC micro-controller architecture (RISC-V architecture a plus) memory-mapped hardware interfaces GPIOs ISRs etc.

• Excellent verbal and written communication skills in English and able to collaborate in a large cross functional organization

• Excellent problem-solving and customer debug skills on real hardware in the lab.

• Experience with using revision control and defect tracking systems (git & Jira or similar).

• Preferred but not required:

  • Experience with SERDES IM-DD/Coherent DSP Ethernet/PCIe PHYs and/or Optical Module SW.

  • Experience with designing/developing/debugging software state machines transitions context saving error handling.

  • Experience with mixed-signal (analogdigital) control and monitoring PID/feedback loop control etc.

  • Experience with bare-metal RTOS device driver Linux kernel etc.

  • Familiarity with advanced compiler options and details (clang/gcc preferred).

  • Proficient in C and Python with knowledge of git Linux makefiles gdb IDEs bash etc.

  • Familiarity with digital verification test flows FPGA emulation hardware languages such as Verilog

  • Familiarity with lab equipment such as oscilloscopes supplies PNAs ONTs etc.

  • Understanding of Ethernet networking from the OSI model with emphasis on the PHY up to the data link level.

  • Familiarity with forward error correction PCS framing PMA/PMD PRBS and other PHY traffic schemes.

  • Understanding of signal processing: histograms BER SNR sampling phase Shannon limit impulse & frequency response FFT etc.
