• Strong experience in protocol testing, validation, and system integration testing.

• Hands-on experience validating industrial communication protocols, including:

o DNP3

o SNMP

o IEC 61850

o Modbus

• Experience in testing and validating communication and file transfer protocols,

including:

o FTP

o FTPS

o SFTP

o TFTP

o HTTP

o ASCII-based protocols

o YMODEM

o XMODEM

• Strong experience in network testing, packet analysis, and protocol validation using

tools such as:

o Wireshark

o tcpdump

o Other network analyzers

• Hands-on experience with Docker for test environment setup, deployment validation,

and container-based testing.

• Ability to interpret vendor manuals and technical documentation to design test cases

and validate device behavior.

• Strong analytical, debugging, and problem-solving skills.

• Excellent communication skills and ability to work in cross-functional Agile teams.

Essential Responsibilities

• Design, develop, and execute manual automated test cases for C# / C++-based

communication systems.

• Validate and test industrial communication protocol stacks and device integration

solutions.

• Perform functional, integration, system, regression, and protocol compliance testing.

• Analyze system and customer requirements to derive test scenarios and acceptance

criteria.

• Perform protocol-level debugging, packet analysis, and root cause analysis of

communication issues.

• Validate interoperability between industrial devices, embedded systems, and software

applications.

• Test and verify file transfer and network communication protocols under different

conditions (load, failure, latency, etc.).

• Work with development teams to identify, log, and track defects using standard defect

management tools.

• Conduct ODBC/database testing, including connectivity, query validation, and data

integrity checks.

• Interpret vendor documentation to design device validation test plans.

• Collaborate with QA, development, product management, and customers to ensure

high-quality software delivery.

• Participate in test planning, reviews, and Agile ceremonies.

• Ensure quality through automation, continuous testing, and CI/CD integration.

• Contribute to improving test processes, frameworks, and automation coverage.

• Ensure systems meet performance, scalability, reliability, and compliance

requirements.

Good to Have

• Knowledge of TypeScript/JavaScript-based test automation frameworks.

• Experience with SCADA systems, industrial automation, or power systems testing.

• Familiarity with performance testing and load testing tools.

Exposure to industrial automation, SCADA, power systems, or embedded communication

software is an added advantage.
