2.  Product Manager (PM)

The Product Manager is responsible for meetings, idea evaluation, technical implementation, and documentation, overseeing the development process and market entry. They strategize, set goals, and closely monitor KPIs. Product Managers keep an eye on competitors and market trends, generate ideas, manage pricing, and facilitate collaboration with various team members, creating a roadmap that outlines what features should be developed and in what order, while staying attuned to market trends.

They act as a bridge between cross-functional teams, including engineers, designers, business analysts, and quality assurance professionals, ensuring everyone shares a common understanding of the product's objectives. PMs define, prioritise, and oversee the development of features, making crucial decisions along the way to maintain the project's momentum.The role of a Product Manager requires an ability to provide a clear vision, lead teams, and adapt to changing market dynamics is crucial for driving a project's success. In essence, Product Managers are the conductors of software development, cordinating market insights, user expectations, and business goals to create products that resonate with users and drive business success.

3.  Technical Lead 

Tech Leads are often seasoned developers with a profound understanding of various programming languages and tools. One of their primary roles is to set the technical direction of a project, ensuring that the development process aligns with best practices and coding standards. Beyond their technical prowess, Tech Leads guide junior developers through the intricacies of software development. They actively engage in code reviews to maintain code quality and consistency. They are also the architects, designing the software's underlying structure to ensure it's scalable, maintainable, and efficient.

Tech Leads are the go-to experts for assessing and mitigating technical risks, preventing roadblocks that could disrupt project timelines, acting as problem-solvers, when technical challenges arise. They bridge the gap between the technical aspects of the project and non-technical stakeholders, ensuring a common understanding of the project's technicalities

4.  Software Developers 

These are the coders who write the software that runs digital world we interact with daily. Their work involves coding in various programming languages, frameworks, and libraries, collaborating with other team members, such as designers, testers, and product engineers. Their role is pivotal in transforming concepts and requirements into functional software applications, as they work seamlessly with their team, participating in code reviews and conducting testing at various levels to maintain quality and consistency. At the core of their responsibilities is coding, where they craft the lines of code that make software work.

They are proficient in programming languages and collaborate with designers, quality assurance engineers, and other team members to ensure that the software aligns with project goals.  They play a significant role in planning the software's structure and how different components will interact and rely on proficient problem-solving abilities to identify and address technical challenges, optimising code for better performance and efficient, scalable, and maintainable software systems.

5.  Quality Assurance Engineer(QA) 

QA Engineers ensure the software functions correctly and meets the highest quality standards. They conduct testing, create automation scripts, and provide detailed bug reports to help developers make improvements. They examine every nook and cranny of the software to identify and rectify defects, bugs, and issues that could hamper its functionality. QA Engineers develop a comprehensive testing strategy, design detailed test cases, and execute a combination of manual and automated testing to evaluate the software's performance, security, and usability. Their watchful eye for detail and analytical thinking allows them to spot even the tiniest discrepancies, and they meticulously document their findings in bug reports that guide the development team in resolving issues.


QA Engineers contribute to a seamless user experience by conducting usability testing, ensuring the software is user-friendly and accessible. They also play a critical role in maintaining a record of test cases, results, working closely with the development team to facilitate efficient bug resolution and communicate test results.
