Key Responsibilities in Detail: The Building Blocks of Your Expertise

The responsibilities of an SDE I are meticulously designed to facilitate a steep and rewarding learning curve. Each task is a building block, intended to develop your technical skills, professional acumen, and problem-solving capabilities in a structured and supportive manner.

1. Assisting in Designing, Coding, and Testing Software Applications

The phrase “assisting in” is key here. It signifies that you are an integral part of the development process, but with a safety net of experience guiding you.

• Deconstructing the Design Phase: You will not be expected to architect a full-scale system on your first day. Instead, you will be included in design review meetings where senior engineers and architects present their solutions for new features or major changes. Your role is to listen actively, ask clarifying questions, and begin to understand the “why” behind the design choices. For instance, why was a particular microservice pattern chosen? Why is this data structure optimal for that specific use case? This exposure is an accelerated masterclass in software design principles.
• The Practice of Coding: Your initial coding assignments will be focused, well-defined components of a larger feature. For example, you might be tasked with developing the API endpoint for a new function in the SingleView system, creating a data transformation script, or building a user interface component for an internal admin tool. Your code will be submitted for review through pull requests, where senior team members will provide constructive feedback on everything from algorithmic efficiency and code readability to adherence to CSG’s coding standards and best practices. This iterative feedback loop is one of the most valuable learning mechanisms you will experience.
• The Imperative of Testing: At CSG, quality is not an afterthought; it is woven into the fabric of our development process. You will be responsible for writing unit tests for the code you develop, ensuring each function behaves as expected in isolation. You will also learn to contribute to integration tests, which verify that different parts of the system work together correctly. This instills a mindset of quality and ownership, teaching you that a developer’s job is not complete until the code is reliably tested.

2. Collaborating with Senior Developers and Learning Best Practices

This responsibility is the cornerstone of your professional development. It transforms this role from a job into an apprenticeship.

• Mentorship as a Standard: You will be paired with one or more senior developers who will act as your technical mentors. They are your go-to resource for questions, big or small. Whether you’re struggling with a complex algorithm, confused about a business requirement, or unsure how to approach a problem, your mentors are there to guide you. They won’t just give you the answer; they will help you develop the reasoning skills to find the solution yourself.
• Absorbing Professional Workflows: Beyond pure code, you will learn the tools and processes that enable a global team to collaborate effectively. This includes mastering our version control system (like Git), understanding our branching strategies, learning how to write meaningful commit messages, and navigating our project management tools (like Jira). You will become proficient in the rituals of Agile/Scrum, such as daily stand-ups, sprint planning, backlog grooming, and retrospectives. This comprehensive understanding of the software development lifecycle (SDLC) is what separates a proficient coder from a professional engineer.

3. Debugging and Fixing Software Issues Under Supervision

Debugging is a rite of passage for every great software engineer. It is a forensic art that hones your logic, patience, and deep understanding of system behavior.

• The Real-World Classroom: You will be assigned bugs and issues from our production support ticketing system. These are not hypothetical exercises; they are real problems reported by real customers. Investigating these issues forces you to trace execution paths, examine log files, analyze data flows, and understand the system at a level that feature development alone cannot provide.
• Systematic Problem-Solving: The “under supervision” aspect ensures you develop a methodical approach. You will learn to start by reproducing the issue reliably, then isolating the root cause, formulating a fix, and rigorously testing that fix to ensure it resolves the problem without creating new ones. This process builds critical thinking skills that are invaluable throughout your career, regardless of the technology you are using.

4. Gaining Proficiency in the Tech Stack and Domain Knowledge

Your academic background provides the theory; this role provides the practical, specialized application.

• Deepening Your Technical Toolkit: The job description mentions a specific set of technologies: C, C++, Perl, Java, SQL, and XML. You will move from a theoretical understanding of these languages to using them in a large, complex, and mission-critical codebase. You’ll learn why C++ might be used for a performance-intensive charging engine, how Java forms the backbone of enterprise services, the power of Perl for scripting and automation, the critical nature of SQL for data manipulation and reporting, and the role of XML in configuration and data exchange.
• Becoming a Domain Expert: Perhaps the most unique aspect of this role is the domain: telecom billing and charging. You will gain insider knowledge of how telecommunication companies manage customer accounts, rate usage, apply discounts, generate invoices, and handle revenue assurance. This specialized knowledge is a highly valuable and transferable skill within the tech industry. Understanding the business context behind the code you write is what allows you to become a strategic partner, not just a technical executor.

Required Skills and Qualifications: The Foundation for Success

To thrive as an SDE I at CSG, you need a solid foundation upon which we can help you build. These are the essential prerequisites we look for in every candidate.

• A Relevant Bachelor’s Degree: A degree in Computer Science, Software Engineering, Information Technology, or a closely related field is required. This credential serves as a proxy for the fundamental knowledge you possess: a solid grasp of data structures (arrays, linked lists, trees, hash maps), algorithms (sorting, searching, complexity analysis), object-oriented programming principles (encapsulation, inheritance, polymorphism), and computer architecture. This theoretical base is non-negotiable for solving the complex problems we tackle.
• Fundamental Programming Proficiency: We do not expect you to be an expert in all languages listed, but we do expect demonstrable proficiency in at least one or two, and the clear aptitude to learn others rapidly.
  • C/C++: Understanding memory management, pointers, and low-level system interaction in these languages demonstrates a strong grasp of computer fundamentals.
  • Java: Proficiency in Java, including its core libraries and understanding of the JVM, is crucial for enterprise application development.
  • SQL: The ability to write efficient queries, understand joins, and manipulate data is essential in a data-intensive domain like billing.
  • Perl/XML: Familiarity with scripting languages like Perl for automation and data-wrangling, and structured data formats like XML, shows versatility.
• A Authentic Learner’s Mindset: This is the most critical soft skill. We are looking for candidates who are inherently curious, humble enough to acknowledge what they don’t know, and proactive in seeking out knowledge. You should view every challenge as a learning opportunity and every piece of feedback as a gift. This mindset is the fuel for your rapid growth within the company.
• Core Problem-Solving Aptitude: Software engineering is, at its heart, the practice of solving problems with code. We look for the ability to logically deconstruct a vague or complex requirement into smaller, manageable steps, and then systematically work through them to devise an effective solution.

Desired Skills / Nice-to-Have: What Makes a Candidate Stand Out

While the following skills are not mandatory, they act as powerful differentiators. They indicate a candidate who can accelerate their contribution and has a pre-existing interest in our specific domain.

• Experience with SingleView or Telecom Billing: This is the most significant advantage. Any prior exposure—through an internship, academic project, or previous role—to telecom billing systems, and especially to CSG’s market-leading SingleView product, is immensely valuable. It means you already understand the domain’s core concepts: rating, charging, billing cycles, invoicing, and settlement. It dramatically shortens your onboarding time and allows you to engage in more sophisticated discussions sooner.
• Knowledge of SingleView Configuration Layer / EPM: The Enterprise Product Model (EPM) and the configuration layer are where the business logic of SingleView is defined. Experience here shows you understand how to customize the product for different client needs—configuring pricing plans, discount structures, and product bundles. This is a highly specialized and sought-after skill set in the telecommunications industry.
• Familiarity with Agile and DevOps Principles: Any hands-on experience with Agile methodologies (Scrum, Kanban) or exposure to DevOps practices (CI/CD pipelines, containerization with Docker, etc.) demonstrates that you understand the modern software development environment and can collaborate effectively within it.
• Exemplary Communication Skills: In a remote work setting, communication becomes your primary mode of presence. The ability to write clear and concise documentation, articulate complex technical concepts in simple terms, ask precise questions, and provide proactive status updates is invaluable. It ensures collaboration remains seamless despite physical distance.

Team Collaboration and Work Environment: Thriving in a Remote-First World

As a remote SDE I in India, you are a vital node in a global, distributed network of talent. How we collaborate is therefore engineered for success, regardless of location.

• Your Immediate Circle: The Scrum Team: You will be embedded in a cross-functional Scrum team. This is your family unit within CSG. It typically includes:
  • Other Software Engineers (SDE I, II, Senior, Lead)
  • A Quality Assurance Engineer who ensures the quality of the team’s output.
  • A Scrum Master who facilitates the process and removes impediments.
  • A Product Owner who represents the voice of the customer and defines the “what” and “why” of the work.
    This team collaborates daily to deliver value in iterative cycles, and you will be a full participant in this process.
• The Digital Toolbox: We leverage a best-in-class suite of collaboration tools to create a cohesive and productive environment. You will become proficient in:
  • Slack/Microsoft Teams: For real-time communication, quick questions, and informal social interaction.
  • Zoom/Webex: For daily stand-ups, sprint planning, design reviews, and one-on-one meetings with your manager.
  • Jira: For tracking your tasks, understanding the sprint backlog, and visualizing the team’s workflow.
  • Confluence: For documentation, knowledge sharing, and creating a single source of truth for project requirements and architectural decisions.
  • GitHub/GitLab: For version control, code review, and managing the entire lifecycle of your code.
• The Rhythm of Remote Work: Success in a remote role requires a blend of discipline and proactive engagement. You are expected to manage your time effectively, create a productive workspace, and be highly available during core collaboration hours. This means actively participating in video calls, responding to messages in a timely manner, and signaling when you are deep in focus work or need assistance. CSG fosters a strong culture of “virtual presence,” encouraging casual coffee chats, virtual team-building events, and dedicated channels for non-work topics to ensure you feel connected, supported, and part of the community.

Career Growth and Learning Opportunities: Charting Your Path Forward
