Rethinking Engineering Hiring: Balancing Specialization and Adaptability
In the world of software development, hiring practices often prioritize deep knowledge of specific frameworks or libraries over broader engineering fundamentals. While specialization has its place, especially in the early stages of a project, problem-solving ability, adaptability, and engineering mindset should be the true focus of hiring practices.
When we differentiate between frameworks (like Angular and Vue.js) and libraries (like React), it becomes clear that engineers need a balanced set of skills to succeed. Frameworks provide more structure, while libraries are more flexible, and mastering either requires a solid foundation in JavaScript and TypeScript.
This mindset needs to change across the industry, with a shift toward evaluating core competencies and on-the-job learning rather than rigid adherence to tool-specific knowledge.
1. The Problem with Framework/Library-First Hiring
In many cases, the hiring process focuses too much on deep knowledge of tools like React, Angular, or Vue.js. But in larger engineering teams, expecting every engineer to be a master of a specific framework or library can be costly and unnecessary. A company’s success depends more on hiring engineers who can solve problems, understand the core technologies, and adapt to new frameworks as needed.
While React is a library that gives developers more flexibility, Angular and Vue.js are frameworks that come with pre-set conventions and structures. Mastering these tools is valuable, but true engineering expertise comes from knowing how to work with JavaScript and TypeScript—the foundations on which these frameworks and libraries are built.
2. When Specialization Matters: Laying the Foundation
There are situations where specialization is crucial, particularly when starting a new project. Expert-level knowledge of a framework or library is important when building the core architecture of a product, ensuring that the technology choices align with long-term goals.
Specialization is most beneficial for leads and experts, who need to understand how to optimize the chosen technology, define best practices, and set the foundation for future development. When building a new product from scratch, having experts who know the ins and outs of a framework or library ensures scalability, security, and performance.
However, it’s important to note that these roles are limited to specific stages of a project. Once the foundation is built, most of the team doesn’t need deep specialization but rather strong problem-solving skills and a good grasp of JavaScript/TypeScript to execute tasks efficiently and contribute to the evolution of the platform.
3. The Cost of Over-Specialization: A Narrow Approach
Specialization comes at a cost. Engineers who focus solely on mastering a framework or library like Angular or React often limit their opportunities, as new technologies emerge and gain traction. This is especially true for junior and mid-level engineers who should prioritize learning core engineering skills over mastering a single tool.

Organizations that overemphasize hiring specialists also miss out on engineers with broader, more adaptable skill sets. Specialization should be reserved for specific, high-value roles that focus on architecture and leadership, while the bulk of the team should be flexible, innovative, and able to learn quickly.
4. Evaluating Candidates: Core Skills Over Tools
Effective hiring processes should focus on engineering fundamentals—skills that remain relevant even as frameworks and libraries change. Here's what to prioritize:
For expert hires, companies should evaluate a candidate’s ability to lead and set the foundation for others, ensuring scalability, security, and proper structure for new projects.
5. Building Teams That Last: A Mix of Experts and Generalists
A successful engineering team is made up of both experts and generalists. Expert hires are critical for laying down a strong foundation when building new products. They bring the deep knowledge necessary to architect robust systems and set the technical direction.
However, the bulk of the team should consist of engineers who can learn on the job and adapt to new frameworks and tools. These engineers don’t need to be React or Angular specialists; they need to understand core technologies like JavaScript/TypeScript, solve problems, and keep projects moving forward.
It’s critical for companies to create an environment where engineers are encouraged to learn new technologies. This not only keeps the team sharp but also ensures that the organization can evolve with industry trends.
Conclusion: Rethinking Specialization in Engineering Hiring
Hiring in the engineering field needs to evolve beyond framework-specific assessments. While specialization is valuable in certain contexts—particularly for expert hires working on new projects—the focus should always be on engineering fundamentals, adaptability, and problem-solving skills. This balance ensures that teams can grow and innovate, while also maintaining the flexibility to embrace new technologies.
By building teams that combine both expert knowledge and adaptability, companies will be better equipped to navigate the ever-changing landscape of software development and achieve long-term success.
