Job Description & Key Responsibilities
Nextpower is a fast‑growing renewable‑energy technology firm that designs and manufactures utility‑scale solar tracker solutions for power plants across India and abroad. With a strong focus on research and development, the company blends mechanical engineering, applied physics and advanced simulation to create high‑efficiency tracking systems that maximise solar capture. The organization prides itself on a collaborative culture where engineers, scientists and product teams work side‑by‑side to push the boundaries of clean‑energy technology.
The Systems Engineering Internship offers postgraduate students a rare chance to dive deep into real‑world R&D projects. Interns will be embedded within the tracker‑design team and will contribute to the entire product lifecycle – from conceptual load calculations to field‑testing of prototype units. This role is ideal for candidates who enjoy hands‑on mechanical analysis, love building simulation models, and are eager to see their designs validated on actual solar farms.
**Key Responsibilities**
1. Perform mechanical and structural analysis of tracker components using ANSYS FEA.
2. Conduct load calculations (static, dynamic, wind) and develop boundary‑condition models.
3. Build and validate simulation models in MATLAB/Simulink for system‑level behavior.
4. Automate repetitive engineering calculations with Python scripts.
5. Create detailed 3‑D models and assemblies in SolidWorks.
6. Assist in design optimisation studies to reduce weight while maintaining strength.
7. Participate in failure‑mode analysis, documenting root‑cause findings.
8. Support field‑testing activities for 3‑6 months, including data collection and on‑site troubleshooting.
9. Prepare technical reports and presentations for cross‑functional teams.
10. Collaborate with electrical, manufacturing and testing engineers to ensure holistic system integration.
**Tech Stack**: SolidWorks, ANSYS (FEA), MATLAB, Simulink, Python, OpenSees (advantage), MS Office for documentation.
**Growth Path**: Successful interns may be offered a full‑time Systems Engineer role, with opportunities to lead larger R&D projects, specialize in advanced simulation, or transition into product management within the renewable‑energy domain.
**Why Join Nextpower?** The internship provides exposure to cutting‑edge solar‑tracker technology, mentorship from senior engineers, and the chance to work on projects that directly impact India’s clean‑energy transition. The blend of office‑based design work and hands‑on field experience makes it a uniquely comprehensive learning opportunity.

❓ 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')).
