What Hard Skills and Soft Skills Do You Need to Succeed as a Software Developer?

Day 53 of 30 days share something challenge.  Playing serious catch up after a crazy work week. This post is making up for missing posting on Wednesday.

This week I created a challenge for my new early career software developers to cement all they had learned from the intensive 6 weeks bootcamp programme I put them through (more on that later). 

On Wednesday I spent the day observing them all navigate their way through trying to achieve the challenge goals, and it really emphasised the importance of hard skills and soft skills in a software developer role.

Most people just focus on the hard skills, but let me tell you dismiss the soft skills at your peril.

So I thought I'd share some of these with you as, whether you’re just starting out or looking to level up, knowing the right mix of hard and soft skills is key to thriving in this role.

Here’s a breakdown of the skills I’ve found essential for success as a software developer:

Hard Skills – The Technical Foundation

These are the skills that give you the tools to code, debug, and build. And yes, they’re what most people think of first!

1. Programming Languages: Start with one or two languages, then expand. Popular ones include Python, JavaScript, Java, and C#. Mastering syntax, structure, and style is key here.
2. Version Control (Git): Knowing how to use Git and platforms like GitHub or GitLab for version control is critical. Collaboration is the heart of development, so Git will be your best friend.
3. Debugging and Testing: Understanding how to find and fix errors is essential. Learn debugging tools and testing frameworks like Jest for JavaScript or Pytest for Python.
4. Web Development Fundamentals: Many developers work on web applications, so knowing HTML, CSS, and JavaScript frameworks like React or Angular can be highly valuable.
5. Databases: Working knowledge of SQL for relational databases (like PostgreSQL or MySQL) and NoSQL databases (like MongoDB) can help you manage and query data effectively.
6. Understanding APIs: APIs are everywhere in software, allowing systems to interact. Learning how to work with RESTful APIs and even build your own is a great asset.

Soft Skills – The Unsung Heroes of Development

These are the skills that allow you to work well with others, solve problems creatively, and keep projects moving forward.

Problem-Solving Mindset: Much of software development is about breaking down complex issues and creating clean, effective solutions. Curiosity and patience go a long way here!

Attention to Detail: A single typo can break an entire application. Strong attention to detail is essential, especially when you’re debugging or reviewing code.

Adaptability: Tech is constantly changing, and every project has unique challenges. Adapting to new languages, frameworks, and tools keeps your skills sharp and makes you a valuable team member.

Communication: Many developers work on teams, so you’ll need to explain your ideas, challenges, and solutions clearly. This includes documentation skills, well-documented code and processes make life easier for everyone.

Collaboration: You’ll often work with designers, product managers, and other developers. Learning how to listen, give feedback, and work as a team is key to creating a successful product.

Time Management: Between coding, testing, meetings, and more, managing your time is crucial. It helps you meet deadlines and manage workloads, which ultimately reduces stress and increases productivity.

Growth Mindset: Tech is all about learning and iterating. Embracing a growth mindset means you see challenges as learning opportunities, which is invaluable when you hit a coding roadblock.

Being a software developer requires much more than knowing how to write code, it’s about bringing together these technical and interpersonal skills to create efficient, user-friendly products.
