This role owns design, development, and integration across .NET/C# based systems with real-time messaging infrastructure (Kafka/Pulsar), collaborating closely with global engineering teams. This is an ownership-driven role - we are looking for a go-getter who takes end-to-end accountability for their systems, not just someone who executes tickets. Key Responsibilities • Architect, design, and develop software components for Advantest’s Semiconductor test orchestration programme, equipment integration, messaging, and data services • Drive Test-Driven Development (TDD) and Behavior-Driven Development (BDD) practices, with strong emphasis on unit and integration test coverage • Remain significantly hands-on in coding, integration, testing, and debugging. • Build cross-platform applications, APIs, SDKs, and services using C#, .NET, and related frameworks • Develop and maintain distributed messaging and data pipelines using Apache Kafka or Apache Pulsar • Work with relational databases (PostgreSQL or similar) for data persistence and telemetry • Debug system-level issues spanning software, communication layers, and integration points • Collaborate directly with global engineering teams (including US-based teams) during design, integration, and deployment cycles • Gather requirements from internal stakeholders and cross-functional/cross-BU partners, clearly communicate tradeoffs and technical decisions • Participate in and lead code/design reviews, mentor junior engineers while staying technically hands-on • Take ownership of features and modules from design through to production deployment Required Qualifications • Strong hands-on expertise in .NET echo system, C#/.NET, including multithreading, asynchronous programming, and API design • Practical experience with a distributed messaging platform - Apache Kafka or Apache Pulsar or any similar platform. • Solid grounding in TDD and BDD methodologies, with real project experience applying them • Working knowledge of TCP/IP, HTTP, and related networking/communication protocols • Bachelor's degree in Computer Science, Computer Engineering, or a related field (or equivalent practical experience) • Strong debugging skills across distributed, multi-component systems • An ownership mentality - someone who proactively identifies problems, drives them to resolution, and doesn't wait to be told what to do Preferred Qualifications • Experience integrating software with hardware, firmware, drivers, or industrial/test equipment systems • Experience working with globally distributed engineering teams, especially in a US-collaboration model • Prior experience in semiconductor, industrial automation, or test & measurement domains (a plus, not mandatory) Additional Requirements • On-site role based in Chennai, India (no hybrid/remote) • Strong written and verbal communication skills - this role requires direct collaboration with global stakeholders • Willingness to occasionally align working hours with global teams for critical integration/deployment windows
