Software Development Engineer Intern - Heizen (Remote/Hyderabad)

Let’s cut the fluff. Most internships are about fixing bugs in a dusty corner of a massive codebase where nobody knows your name. You get a task, you do it, you go home.

Heizen is not that.

Look at the founders' pedigree: Ex-Microsoft, JP Morgan, IIT, and ISB. These are heavy hitters. They are building an "AI-powered" software services model. This means they aren't just writing code; they are figuring out how to use AI to write code faster and better.

If you join here, you aren't just an intern; you are a test pilot for the future of software engineering. You will be doing "Full-Stack" in the truest sense—Web, Mobile, Backend, and Cloud. If you want to condense 3 years of learning into 6 months and work directly with founders who have "been there, done that" at the highest level, this is the JD you need to crack.

1. Why This Job is an Amazing Opportunity

✅ Mentorship from the Top 1% of the Industry

The biggest asset at the start of your career isn't your salary; it's who you learn from. The founders come from Microsoft and JP Morgan. These are people who have built systems that handle billions of dollars and millions of users. Working directly under them (in a startup environment) is like getting a free Master's degree in "How to Build Scalable Software." You will learn coding standards and architectural patterns that usually take years to pick up.

✅ You Won't Be Pigeonholed (Web AND Mobile)

Did you notice the "Requirements" section? They want both Web (React/Next.js) and Mobile (React Native/Flutter). Most roles force you to pick one. Heizen wants a "Swiss Army Knife." This is rare. By working on both platforms simultaneously, you become a "Product Engineer"—someone who can build the entire product, not just one screen. This makes you incredibly valuable (and expensive) in the job market later.

✅ A Clear Path to a PPO (Pre-Placement Offer)

The stipend is ₹25,000, which is decent for a startup, but the real gold is the PPO. They explicitly state: "Outstanding interns may receive full-time offers." Startups hire interns because they want to mold them into full-time engineers who already know the codebase. If you perform well here, you skip the brutal placement season grind and graduate with a job in hand.

2. Role Details

3. The "What, How, & Why" of This Role

What You Will Actually Do:

You are joining a services startup that uses AI. This means speed is everything.

• The Builder: You might start the week building a React dashboard for a client's analytics. By Wednesday, you could be tweaking a React Native mobile app to ensure the login flow works on Android.

• The Client Facer: Unlike big corps where interns are hidden, here you will "Support client interactions." You might have to demo the feature you built directly to a client. This is scary but builds massive confidence.

• The Architect: You won't just follow tickets. You will sit with senior engineers and ask, "Should we use SQL or NoSQL for this?" and actually influence the decision.

How You Can Succeed in the First 90 Days:

• Month 1 (The Sponge): Master their specific stack. If they use Next.js, don't just write React code; learn Server Side Rendering (SSR). If they use Flutter, understand the Widget tree. Don't be afraid to ask the founders "Why did we choose this?"

• Month 2 (The Shipper): Take ownership of one small feature from start to finish. E.g., "Add a 'Dark Mode' toggle." Do the UI, the state management, and the user preference saving in the DB. Ship it.

• Month 3 (The Owner): Start handling client feedback. If a client says "This button is slow," debug it, fix it, and tell them "It's fixed" yourself.

Why This Role is a Stepping Stone:

"Ex-Microsoft Founder" on your resume as a reference is powerful. It signals that you survived a rigorous environment. Even if you don't take the PPO, having "Full Stack (Web + Mobile)" experience makes you eligible for almost every startup role in India. You are proving you can handle the chaos of 0-to-1 building.

4. Interview Preparation Guide

Since this is a startup founded by elite engineers, expect the interview to be practical and problem-solving oriented, not just LeetCode.

Where to Practice :

• Build > LeetCode: For this specific role, a GitHub portfolio with one solid Full Stack project is worth more than 500 LeetCode stars. Build a "Task Manager" that works on Web (Next.js) and has a companion Mobile App (React Native/Flutter) that syncs data.

• System Design Lite: Startups love asking, "How would you build WhatsApp?" Focus on the database schema and API design.

5. Key Concepts to Revise

Concept 1: Next.js (The Modern Web Standard)

Focus: Client vs. Server Components, SEO Optimization, and Next.js 14 Routing.

📺 Master Class Video: Next.js Full Course 2024 | Build and Deploy a Full Stack App Using the Official React Framework

This 3+ hour course is the definitive guide. It doesn't just show you "Hello World"; it builds a complete full-stack application. It explicitly covers the transition from React's useEffect (client-side) to Next.js Server Actions, which is the #1 topic discussed in modern frontend interviews.

Concept 2: Cross-Platform Mobile (React Native or Flutter)

Focus: Native Components, Navigation (Stack/Tab), and Mobile State Management.

📺 Master Class Video: React Native Crash Course

If you know React, this video bridges the gap to Mobile instantly. It explains how <View> replaces <div> and how to handle the specific "quirks" of mobile development like the Safe Area View (the notch on iPhones) and native routing, which web developers often struggle with.

Concept 3: TypeScript (The Safety Net)

Focus: Interfaces, Types, Generics, and strict typing for API responses.

📺 Master Class Video: TypeScript - The Basics

In a fast-paced environment, you don't have time for 10-hour courses. Fireship breaks down the critical "Why" and "How" of TypeScript in under 15 minutes. He explains how to define an interface for your props and data models, which is the immediate safety net you need to demonstrate in a coding challenge.

Concept 4: API Design (REST vs GraphQL)

Focus: HTTP Methods (GET/POST), Status Codes, and designing clean endpoints.

📺 Master Class Video: What is REST?

This video strips away the complexity. It clearly defines the constraints of REST architecture without getting bogged down in academic theory. It explains exactly what a resource is and how to name your routes (e.g., /users/123 instead of /getUserById), which is a common interview whiteboard question.

Concept 5: Deployment & Cloud Basics

Focus: EC2 setup, SSH keys, Environment Variables, and PM2 process management.

📺 Master Class Video: Hands on Practice with EC2 machines

Hitesh is excellent at simplifying cloud infrastructure for developers. This video walks you through the intimidating part: logging into a black-screen Linux terminal (SSH), setting up your environment, and keeping your app running forever, which is the practical "DevOps" skill expected of a Full Stack Engineer.

6. Real-World Interview Questions

❓ Practical: "I want to build a food delivery app. Walk me through your database schema. What tables do you need?" (Hint: Users, Restaurants, MenuItems, Orders).

❓ Mobile vs Web: "You have a feature working on React Web. What challenges will you face moving it to React Native?" (Answer: No HTML/CSS, different navigation, platform-specific UI).

❓ Scenario: "We need to launch this feature by Friday, but the API isn't ready. What do you do?" (Answer: Mock the API data and build the frontend so it's ready to plug-and-play).

❓ Culture: "Tell me about a bug that took you hours to fix. What was it?" (They want to see your debugging struggle and persistence).

❓ Technical: "Explain Prop Drilling in React and how you solve it." (Context API, Redux, Zustand).

7. Why Join Heizen?

The "Founder-Led" Advantage

At a big company like Amazon, you are 10 layers away from the person making decisions. At Heizen, you are likely sitting on a Zoom call with the founders. You get to see how they negotiate with clients, how they prioritize features, and how they handle crises. This business exposure is invaluable if you ever want to start your own company.

The "AI-First" Exposure

The description says "Proprietary AI agents." This implies they are automating parts of the dev process. Being exposed to this early means you won't be the engineer replaced by AI; you will be the engineer managing the AI.

Remote + Hyderabad Hybrid

They offer a "Remote work culture" but are based in Hyderabad. This is the sweet spot. You have the freedom to work from home, but (presumably) if you are in Hyderabad, you can meet the team for "Retreats and Offsites." It’s a modern, flexible setup that respects your time.

8. FAQs

Q: I only know React but not Mobile. Should I apply?

A: Yes. But be honest. Say, "I am strong in React/Next.js and because I know React, I can pick up React Native very quickly." Show willingness to learn.

Q: Is the stipend fixed?

A: Usually, ₹25k is the standard base. If you have exceptional projects or previous internship experience, startups are sometimes flexible, but generally, for interns, the learning value > the extra ₹5k.

Q: What does "Pre-placement offer based on performance" mean?

A: It means there is no guarantee. It is an extended interview. If you ship code, communicate well, and fit the culture, they will offer you a full-time job. If you slack off, the internship ends.
