Job description

Greetings from Wipro

We are pleased to share an exciting opportunity for the Embedded Firmware Developer Optical Plugables role at Wipro.

Role Details

Role: Embedded Firmware Developer Optical Plugables

Location: Bengaluru

Work Model: Hybrid minimum 3 days

Experience: Multiple levels: Software Engineer 4+ years, Senior Engineer 6+ years, Lead Engineer 8+ years

Role Summary

The Embedded Firmware Developer will be responsible for the design, development, enhancement, debugging, and sustaining of embedded software/firmware for optical pluggable products. The engineer will work as part of an Agile/Scrum team and take ownership of assigned features and defects through design, implementation, integration, validation, and closure.

Key Responsibilities

• Design and develop embedded firmware/software using C/C++.
• Develop software for multithreaded RTOS and/or Embedded Linux environments.
• Work with low-level embedded concepts including:
  • Interrupts
  • Device drivers
  • Memory management
  • Hardware/software interfaces
• Perform object-oriented design and apply appropriate software design patterns.
• Develop and maintain firmware functionality for optical pluggable products.
• Direct optical-pluggables development: CMIS/SFF, coherent ZR/ZR++ modules, firmware upgrade, and module state management
• Work on optical/networking areas including:
  • CMIS
  • OTN
  • DSP/line configuration
  • Optical module management and control
• Analyze and resolve:
  • Software defects
  • Customer-reported issues
  • Integration issues
  • Sustaining/maintenance issues
• Perform code reviews, unit testing, integration testing, and defect resolution.
• Develop supporting utilities and automation using Python, where applicable.
• Use Git for source-code management and JIRA for Agile lifecycle/defect management.
• Collaborate closely with QA engineers for feature validation and defect reproduction.
• Participate in sprint planning, estimation, daily scrum, technical reviews, and release-readiness activities.
• Maintain technical documentation and contribute to knowledge retention within the team.
• Use approved AI-assisted engineering tools for design, coding, debugging, testing, or documentation where applicable, with appropriate engineering review.

Mandatory Technical Skills

• Strong programming experience in C/C++, particularly embedded/device software.
• Strong understanding of:
  • Multithreading
  • RTOS and/or Embedded Linux
  • Interrupt handling
  • Device drivers
  • Memory management
• Object-oriented design and software design patterns.
• Debugging and root-cause-analysis skills.
• Experience with Git and JIRA.
• Experience working in Agile/Scrum development environments.

Preferred Domain Skills

• Optical pluggables / optical transceivers.
• CMIS.
• OTN.
• DSP and optical line configuration.
• Telecom/networking embedded systems.
• Python scripting and automation.
• CI/CD exposure.

Expectations for Senior / Lead Developers

In addition to the above:

• Own complex feature design and implementation.
• Provide technical leadership within the scrum team.
• Review architecture/design and code.
• Mentor junior engineers.
• Lead complex defect/root-cause investigations.
• Coordinate technical dependencies with Nokia stakeholders.
• Drive engineering quality and predictable sprint delivery.

Most important screening recommendation

For the Developer, prioritize genuine embedded C++ + RTOS/Linux + optical-pluggable/CMIS experience rather than generic application C++ experience.
