Do you feel like you have hit a ceiling in your current development role? Are you writing code that works but doesn't actually touch the real world? Many developers reach the six-year mark and wonder, "What is next?" You might be tired of small projects that disappear in a year. You might want to work on systems that actually power cities, nuclear energy, and global infrastructure.
If you are looking for a role that combines technical depth with massive real-world impact, this is it. AtkinsRéalis is looking for a Senior Application Developer II. This is not just another coding job. It is a chance to step into a stable, high-growth environment. You will solve complex problems using .NET and Azure. You will mentor others. You will build a career, not just a resume. Are you ready to upgrade your professional life?
✅ Work on Projects That Matter
At most IT firms, you build apps for shopping or social media. At AtkinsRéalis, your code supports engineering, nuclear energy, and infrastructure. This company has been around since 1911. They are currently merging technology with physical engineering to change how the world works. When you write code here, you are helping to manage data for massive construction or energy projects. This gives your work a sense of purpose that is hard to find elsewhere. You will be proud to tell people where you work.
✅ Master the Full Microsoft Ecosystem
This role is unique because it requires you to bridge the gap between the past and the future. The job description explicitly asks for skills in the older .NET Framework and the modern .NET Core. It also demands expertise in Azure AD and SSIS (SQL Server Integration Services). This means you will not just be a "coder." You will become a migration and modernization expert. Learning how to move legacy systems to the cloud is one of the most high-paying skills in the market right now. You will learn it here.
✅ A Culture That Respects Your Life
The tech industry is famous for burnout, but AtkinsRéalis operates differently. They offer a "Total Reward" package and a true hybrid working model. They focus on work-life balance because they know engineering takes clear thinking. They are also a "Disability Confident" and inclusive employer. This means you are joining a safe, supportive environment where you can stay for the long term. It is a place where you can raise a family, have hobbies, and still grow your career.
Category | Details |
Role | Senior Application Developer II |
Location | Bangalore, Karnataka (Hybrid Work Model) |
Eligibility | Bachelor's Degree (BE - ISE/CSE or MCA preferred) |
Experience | 6+ Years of Software Development Experience |
Primary Skills | .NET Framework, .NET Core, C#, Azure AD, SSIS |
Job ID | R-135262 |
What You Will Actually Do
The job title says "Developer," but the day-to-day work is much broader. You will act as a technical anchor for the team. Your main task is to design and maintain software using C# and .NET. However, you will also be the "security gatekeeper." The job requires strong knowledge of Azure AD (Active Directory). This means you will set up how users log in and access data securely. You will also handle data flow. The mention of SSIS means you will write scripts to move large amounts of data between databases. You are not just building screens; you are building the pipes that move data and the locks that keep it safe.
How You Will Succeed in the First 90 Days
To win in this role, you need to be adaptable. In your first month, focus on understanding their existing "Legacy" applications built on the older .NET Framework. Don't look down on old code; understand why it was written that way. By month two, you should start suggesting how to modernize these parts using .NET Core. You should also start picking up the SSIS packages. If you can fix a broken data pipeline or speed up a slow SQL query in your first 90 days, you will prove your value instantly. Also, start mentoring. The JD specifically asks you to guide junior developers. If the juniors trust you, the management will trust you.
Why This Role is a Career Stepping Stone
This is a "Senior II" role. In the hierarchy of corporate IT, this is the final step before you become a Lead Developer or a Solution Architect. By working here, you prove you can handle "Enterprise" scale problems. You will deal with complex authentication (Azure AD) and complex data (SSIS). These are the two hardest things to get right in software. Once you master these at AtkinsRéalis, you qualify for Architect roles in almost any banking, healthcare, or engineering firm. This job prepares you for the highest bracket of technical salaries.
To help you crack the interview, we have researched the specific technical requirements for this role. Since this is a senior role (6+ years), they will not ask you basic questions. They want to know if you understand how systems work together.
Where to Practice:
Technical Coding: Go to LeetCode. Focus on "Medium" difficulty problems. Look specifically at "String Manipulation" and "Hash Maps."
System Design: Since this is a senior role, search for "System Design Primer" on GitHub. Read about how to design scalable systems.
Azure Practice: Use the Microsoft Learn free sandbox to practice setting up Azure AD users and permissions.
Key Concepts to Revise:
Dependency Injection (DI) in .NET Core:
You must know this inside and out. Explain how .NET Core manages object lifecycles (Transient, Scoped, Singleton). This is vital because the role involves modern .NET Core development where DI is the backbone.
Azure AD & OAuth 2.0:
The JD highlights "Azure AD authentication." You need to understand the difference between Authentication (who you are) and Authorization (what you can do). Revise the flow of tokens (Access Tokens vs. Refresh Tokens).
SSIS & ETL Processes:
This is a specific requirement. Brush up on how to create a package, how to handle errors in data transfer, and how to deploy an SSIS package to a server. They need you to move data reliably.
Asynchronous Programming (Async/Await):
For a senior developer, blocking the main thread is a crime. You must explain how async and await work in C#. Explain how this helps the application handle more users at the same time without freezing.
SOLID Principles:
You are expected to write clean code and mentor juniors. You must be able to explain each letter of SOLID with a real-world C# example. For instance, how does the "Single Responsibility Principle" apply to a C# Class?
Real-World Interview Questions (Glassdoor Style):
❓ Technical: What is the difference between .NET Core and .NET Framework, and what challenges would you face migrating from one to the other?
❓ Core C#: Can you explain the difference between IQueryable and IEnumerable? When would you use one over the other in a database call?
❓ Azure: How do you secure a web API using Azure AD? Explain the handshake process.
❓ Scenario: We have a slow-running SSIS package that processes 1 million records. How would you debug and optimize it?
❓ Behavioral: Tell us about a time you found a critical bug in production. How did you handle it, and how did you communicate it to the stakeholders?
❓ Leadership: How do you handle a code review where a junior developer has written working code, but it follows bad practices?
AtkinsRéalis is a global powerhouse. They are not a startup that might run out of cash next month. They are a world-leading professional services and project management company. They operate in strategic sectors like Nuclear, Clean Energy, and Transportation. This means the market demand for their work is always high. When you join them, you join a legacy of excellence.
The culture is "People First." They invest heavily in training. The JD mentions that they support staff in achieving corporate memberships and offer a wide training portfolio. They want you to get smarter. They want you to move up. If you are bored of stagnation, this is the place to restart your growth engine.
Finally, they are truly inclusive. They have pledges for Women's Equality and are a "Disability Confident" employer. This shows they value diverse perspectives. It creates a work environment that is less toxic and more collaborative. You can be yourself here.
Q: Do I need experience with the old .NET Framework?
A: Yes. The job description explicitly asks for "Extensive experience with the older .NET Framework." You will likely be maintaining or migrating older systems, so knowledge of the history of .NET is crucial.
Q: Is this a remote job?
A: It is a Hybrid role based in Bangalore. AtkinsRéalis emphasizes flexibility, but you will be expected to come to the office for collaboration.
Q: What is the preferred education background?
A: They prefer a Bachelor's degree in Engineering (BE - ISE/CSE) or an MCA (Master of Computer Applications). However, strong experience often outweighs the specific degree title.
