It is easy and simple to learn and use and is powerful, fast, and secure. This object-oriented programming language lets the code be reused that automatically lowers the development cost. Java is specially used for android apps, web and application servers, games, database connections, etc. This programming language is closely related to C++ making it easier for the users to switch between the two.

What skills help Senior Web Application Developers find jobs?

Tell us what job you are looking for, we’ll show you what skills employers want.

What skills stand out on senior web application developer resumes?

Dr. Brock LaMeres Ph.D.

Professor, Electrical & Computer Engineering, Director, Montana Engineering Education Research Center (MEERC), Montana State University

All companies are looking for some experience beyond the classrooms. This can be through internships or doing research at their universities. But students still need to show an acceptable GPA to show employers that they understand the fundamentals of their discipline.

What soft skills should all senior web application developers possess?

Sal Aurigemma Ph.D.

Associate Professor of CIS, J. Bradley Oxley Professor of Computer Information Systems, University of Tulsa

All the soft skills are important, but a few are absolutely critical in today's hybrid workforce. With the uncertainty of COVID delaying the return to the office, many companies are embracing hybrid work and/or 100% remote for some or all of their employees. Today's employees must be able to effectively communicate over a range of different modalities, both synchronously and asynchronously, while still being able to actively build and maintain relationships as they participate in one or more teams of coworkers, customers, and other stakeholders. Today's IT workers need to be honest with themselves on the work environments they can and cannot succeed within.

What hard/technical skills are most important for senior web application developers?

Sal Aurigemma Ph.D.

Associate Professor of CIS, J. Bradley Oxley Professor of Computer Information Systems, University of Tulsa

Students graduating with Information Systems and related degrees usually have little problem finding employment upon graduation. However, the pandemic upended that paradigm for some. For those who recently graduated and are still looking for employment, keep the faith and develop your technical skills. Developers should show prospective employers that they are familiar with agile programming methodologies and modern DevOps stacks and processes. Data analysts should be focused on presenting their ability to work with structured and unstructured data, effectively query data using SQL & NoSQL, and, most importantly, provide actionable insight by making data accessible and relatable to decision-makers at all levels of an organization. Those interested in cloud architecture and cyber security careers have to keep current on their skills and certifications. Cloud engineers need to stay aware of the constant changes happening at the major providers (AWS, Azure, GCP) and, as with all other IT fields, provide tangible evidence of your skills via real projects that you have worked on. Prospective cyber security analysts should first focus on identifying their first specialization because there are too many security roles to learn them all at once, especially as beginners. Two popular entry-level cyber security jobs include information security consultant and Security Operations Center (SOC). Both of these roles require a sound foundation in networking fundamentals, vulnerability identification and mitigation, and an understanding of organizationally relevant security and privacy frameworks and regulations.

What senior web application developer skills would you recommend for someone trying to advance their career?

Brian Law

Assistant Professor of Computer Science, Illinois Wesleyan University

There are several areas that are "hot" right now, such as the previously-mentioned data science, artificial intelligence, and systems, but also cybersecurity and databases/data warehousing. That being said, the most important thing for a new graduate seeking employment to do is just to do anything, produce something. Tech employers don't and have never trusted computer science credentialing; that mistrust is the origin of the infamous "tech interview," used to verify whether a candidate actually has the technical skills to back up their piece of paper.

So to preemptively answer that question and get a leg up on other candidates, graduates should be sure to generate some artifact(s) that demonstrate(s) their technical and organizational skills. Show them that you can plan a project, design it, see it through in programming it, and do so in a responsible, organized manner (good coding style, readable code, well-documented, and using proper version control), and you'll have addressed your future employer's greatest worries right off the bat.

If it's a project in one of these "hot" areas or specifically tuned for the work the employer does, all the better, but anything the employer is doing is probably leagues beyond what a fresh graduate can do by themselves in a few months, so ultimately they're not going to be that impressed with your domain-specific technical knowledge. Instead treat it more as an opportunity to show off your "soft" skills, your programming maturity, and your ability to actually produce a product rather than just answer exam questions. And while you're at it, you might as well make it something fun for yourself so you'll be driven to finish it.

What type of skills will young senior web application developers need?

Dr. Shaun Cooper Ph.D.

College Associate Professor, New Mexico State University

Most young graduates want to be game developers. Frankly, there are too few jobs in game development for students to find a reasonable change. The skills employers want are in using SQL with relational databases, and they want the ability to work in a full stack development environment and the willingness to learn new platforms and programming environments. The employer has a huge investment in their development stack, and the new employee has to learn that stack. Also, they want employees with the ability to communicate with management and, most importantly, the ability to work with others. The graduate should be solid in basic data structures and how they are applied to solutions. Additionally dynamic HTML web services are welcome.

What technical skills for a senior web application developer stand out to employers?

Bob Sweeney Ph.D.

Associate Professor, University of South Alabama

Strong database skills including big data and SQL are always valued by local employers hiring our IS majors. While not technical, written and verbal communications skills are always important.
