Job Description & Key Responsibilities
Texas Instruments (TI) is a global leader in analog and embedded processing semiconductor solutions, with a strong presence in India. The company’s Bengaluru campus houses the Radar Firmware group, which designs and delivers cutting‑edge mmWave radar sensors used in automotive ADAS, autonomous driving, industrial automation, drones and many other high‑impact applications. TI’s culture emphasizes innovation, cross‑functional collaboration, and a commitment to safety‑critical product development, making it an attractive destination for fresh engineering talent.
The role of Software Engineer – Embedded Firmware focuses on creating safety‑certified firmware for TI’s mmWave radar portfolio. The engineer will work closely with hardware designers, system architects and test teams to deliver reliable, real‑time code that meets ISO 26262 ASIL‑D and IEC 61508 SIL‑3 standards. This position offers a unique blend of low‑level programming, hardware‑software integration, and exposure to advanced radar technology, providing a solid foundation for a career in semiconductor and automotive embedded systems.
Key responsibilities include:
1. Design, develop and maintain bare‑metal firmware for radar sensors and processors using C and Assembly.
2. Implement real‑time control loops for sensor configuration, calibration and high‑speed data acquisition.
3. Ensure compliance with safety standards (ISO 26262, IEC 61508) by incorporating diagnostic coverage and fault‑tolerant mechanisms.
4. Debug firmware using JTAG, trace tools and logic analyzers, and resolve hardware‑software integration issues.
5. Develop automated test suites and CI/CD pipelines to validate firmware performance and reliability.
6. Create customer evaluation applications and provide technical support during field trials.
7. Collaborate with cross‑functional teams to define firmware requirements and release schedules.
8. Participate in code reviews, documentation and knowledge‑sharing sessions.
9. Contribute to continuous improvement of development processes and tooling.
10. Stay updated with emerging radar technologies and industry best practices.
The tech stack revolves around C, Assembly, Python/Perl/Lua scripting, embedded Linux tools, JTAG/debuggers, and version‑control systems like Git. Candidates will gain exposure to high‑frequency radar signal processing, safety‑critical development workflows, and large‑scale product releases. Growth paths include senior firmware engineer, lead firmware architect, system‑level firmware manager, or transition into system‑level hardware design roles within TI’s broader semiconductor ecosystem. Joining TI means working with world‑class engineers, accessing state‑of‑the‑art labs, and contributing to products that shape the future of mobility and sensing.

❓ Core Technical Questions & Answers
What is the difference between Implicit Wait, Explicit Wait, and Fluent Wait in Selenium? Answer ▼
Model Answer: Implicit Wait sets a global timeout for all element lookups. Explicit Wait pauses execution until a specific ExpectedCondition (e.g. elementToBeClickable) is met. Fluent Wait allows defining polling frequency and ignoring specific exceptions like NoSuchElementException.
Explain the Page Object Model (POM) and its advantages in Test Automation. Answer ▼
Model Answer: POM is a design pattern that creates an object repository for web UI elements. It separates test scripts from page locators, reducing code duplication and making maintenance easy when UI elements change.
How do you handle dynamic WebElements whose ID changes on page reload? Answer ▼
Model Answer: Use dynamic XPath methods like contains(), starts-with(), text(), or XPath axes (ancestor, following-sibling, parent) instead of brittle absolute paths.
What is the difference between @BeforeMethod and @BeforeClass in TestNG? Answer ▼
Model Answer: @BeforeClass runs once before the first test method in the current class, while @BeforeMethod executes before each individual test method.
How do you validate REST API response codes and JSON payload using Postman / RestAssured? Answer ▼
Model Answer: In RestAssured: given().when().get('/endpoint').then().assertThat().statusCode(200).body('status', equalTo('ACTIVE')).
