Test Engineer (PCBA) at Siemens in Goa, IN

We're improving the way we live and work by intelligently connecting energy systems, buildings, and industries!!

Smart infrastructure from Siemens makes the world a more connected and caring place – where resources are valued, where impact on the world is considered, where sustainable energy is delivered optimally and efficiently. It provides the flexible infrastructure to allow society to evolve and respond to changing conditions. Technology and the ingenuity of people come together to be at one with our environments and to care for our world. We do this from the macro to the micro level, from physical products, components, and systems to connected, cloud-based digital offerings and services. Siemens offers a broad portfolio of grid control and automation; low- and medium-voltage power distribution, switching and control; and building automation, fire safety and security, HVAC control and energy solutions.

JOIN US! WE MAKE REAL WHAT MATTERS. THIS IS YOUR ROLE

Key Responsibilities

Test Engineering & Optimization

• Develop, validate, and maintain ICT (In‑Circuit Test), FCT (Functional Circuit Test), and Boundary Scan (B‑Scan/JTAG) test programs for PCBA.
• Define optimal test strategies combining ICT, B‑Scan, and FCT to maximize coverage and minimize escapes.
• Support test fixture development, probe optimization, and overall test coverage improvement.
• Optimize test programs to improve First Pass Yield (FPY) while reducing false failures and retest rates.

Statistical Analysis & Drift Monitoring

• Monitor component parameter drift and behavioral changes over time using production and test data.
• Perform histogram analysis, distribution studies, trend monitoring, Cp/Cpk, and statistical correlation analysis.
• Identify shifts caused by component aging, supplier variation, and manufacturing process drift.
• Refine ICT/FCT/B‑Scan test limits, algorithms, and guard‑bands based on statistical evidence.
• Establish data‑driven criteria to clearly differentiate normal process variation from true failure conditions.

Failure Analysis & Root Cause

• Perform in‑depth electrical and functional failure analysis on PCBA defects.
• Debug issues related to components, solder joints, assembly process, design margins, and test coverage gaps.
• Apply systematic root cause methodologies such as 5‑Why, Fishbone, Pareto, and correlation analysis.
• Drive corrective and preventive actions with design, process, quality, and supplier teams.

Automation & Programming

• Develop and enhance test programs, analysis scripts, and automation tools using:
• VB.NET
• Python
• C++
• Automate test data collection, report generation, statistical analysis, and failure trend monitoring.
• Support integration of test systems with MES, databases, and cloud platforms where applicable.

Electronics & Debug

• Strong foundation in analog and digital electronics.
• Ability to read and interpret schematics, layouts, BOMs, and test specifications.
• Hands‑on experience debugging PCBA‑level electrical and functional issues.

PCBA Assembly Process Knowledge

• Strong understanding of SMT, THT, reflow soldering, wave soldering, and typical assembly defects.
• Ability to correlate assembly process variation with test behavior and failures.

Qualifications and Skills:

• Bachelor’s degree in Electronics Engineering, or related field with 3+ years of experience in PCBA trsting..
• Strong proficiency in advanced statistical analysis
• Proficiency in programming languages and software tools used for test development (e.g., LabVIEW, VB.net, Python, C/C++).
• Knowledge of Boundary scan technology.
• Knowledge on microcontrollers and its basics.
• Proven experience in in-circuit testing and electronic test engineering.
• Familiarity with in-circuit testing equipment, such as flying probe testers and bed-of-nails testers.
• Strong understanding of electronic components, circuit board design, and manufacturing processes.
• Knowledge on board level programming and communication protocols (JTAG, SPI, Serial – USB and RS232, Ethernet, GPIB)
• Excellent problem-solving skills and attention to detail.
• Effective communication and collaboration abilities.
• Proven team player, high on collaboration with partners.
