SPAN is hiring a Systems Integration Engineer

About the Role

You will lead the integration and validation of complex hardware and software systems, ensuring they perform as intended across real-world conditions. Working at the intersection of firmware, software, and electrical engineering, you'll design test strategies, build test environments, and drive lab-based validation efforts to verify system behavior and reliability.

What You'll Do

  • Collaborate with product, firmware, and software teams to define integration approaches and test objectives
  • Develop detailed test plans, regression suites, and automation frameworks to validate system performance
  • Design and assemble test rigs to simulate real-world operating conditions
  • Lead hands-on testing in the lab, including stress testing and fault injection to uncover edge cases
  • Characterize system behavior—measuring response times, communication latency, and power performance
  • Reproduce field issues, identify root causes, and work with engineering teams to validate fixes
  • Automate testing workflows using CLI tools and frameworks like pytest to improve efficiency
  • Interface with embedded systems using protocols such as REST, CAN, and Modbus to validate integration
  • Use oscilloscopes, logic analyzers, and power analyzers to debug electrical behavior
  • Document findings, share insights across teams, and contribute to product improvements

Requirements

  • Bachelor’s degree in electrical engineering or a related field, or equivalent practical experience
  • 5+ years working with hardware systems, power electronics, and electrical fundamentals, including reading PCBA schematics
  • 3+ years applying formal systems engineering practices in product development
  • 2+ years using CLI tools, Linux environments, and test automation frameworks like pytest
  • 2+ years working with communication protocols such as REST, CAN, or Modbus
  • Proven experience with electrical test equipment including oscilloscopes, logic analyzers, and power analyzers
  • Strong hands-on electrical skills—comfortable with residential wiring, soldering, and circuit debugging
  • Ability to clearly communicate technical concepts across disciplines in writing, diagrams, and conversation
  • Self-driven with a curiosity to explore complex systems and learn beyond defined boundaries

Preferred Qualifications

  • Experience diagnosing and troubleshooting systems remotely
  • Background in energy storage, inverters, EVSE, or similar power electronics hardware
  • Programming experience in Python, JavaScript, or other scripting languages
  • Familiarity with numerical analysis tools such as Pandas, MATLAB, or R
  • Experience reading and interpreting embedded system source code and state machine logic
  • Knowledge of residential electrical systems and safety standards
  • Experience with SQL and data visualization for test analysis
  • A practical, problem-solving mindset—driven to make systems work, even when they’re not designed to

Benefits

  • Generous paid leave policy
  • Comprehensive health and insurance benefits
  • Office located in central Bengaluru with easy access to transit, dining, and urban amenities
