What is a freelance junior software developer?

Freelance Junior Software Developers are entry-level programmers who work independently, often on a project-by-project basis, for various clients. They are responsible for writing, testing, and maintaining code under the guidance of more experienced developers or according to client specifications. As freelancers, they have the flexibility to set their own schedules and choose projects, but they also need to manage their own workload and seek out new opportunities. This role is ideal for those starting their software development careers and looking to gain diverse experience across different industries or technologies.

What skills and qualifications are needed to thrive as a freelance junior software developer?

To thrive as a Freelance Junior Software Developer, you need a foundational understanding of programming languages (such as JavaScript, Python, or Java), version control (like Git), and a portfolio demonstrating relevant projects. Familiarity with integrated development environments (IDEs), code repositories (GitHub), and sometimes certifications in web development or specific frameworks are commonly expected. Strong communication, time management, and problem-solving skills help you collaborate effectively with clients and manage multiple projects independently. These skills and qualities are crucial for delivering reliable code, building client trust, and succeeding in a competitive freelance environment.

What are common challenges freelance junior software developers face when starting out, and how can they overcome them?

Freelance Junior Software Developers often encounter challenges such as finding consistent work, managing client expectations, and adapting to a variety of project requirements. Building a strong portfolio, networking within developer communities, and setting clear communication with clients can help overcome these hurdles. Additionally, learning project management basics and familiarizing oneself with common tools for remote collaboration can make it easier to handle multiple projects and clients. With time and experience, freelancers typically gain more confidence and establish a steady workflow.

Description
SG is a boutique technology company founded in 2004. We use technology and big data to solve real world financial puzzles. Our competitive advantage is a true meritocracy minimizing politics and rewarding results. The foundation of our culture is continuous improvement. 
We are looking for a forward-thinking Junior Software Engineer to join our development team. This isn't your traditional "code-by-the-book" role. We are looking for someone who is not only proficient in the technical foundations of C++ but also treats AI development tools as a core part of their workflow to increase efficiency, code quality, and problem-solving speed.
You will work on high-performance applications, while simultaneously helping our team define the cutting edge of AI-integrated software engineering.
Responsibilities:
  • C++ Development: Write clean, maintainable, and efficient code in C++ for core system components.
  • AI Integration: Actively use AI coding assistants (e.g., Claude, Codex, GitHub Copilot, Cursor, LLMs) to accelerate prototyping, debugging, and unit test generation.  Experience creating and refining, .md files, mcp servers, skills and agents.
  • Code Review & Quality: Participate in peer code reviews, ensuring that AI-generated suggestions meet our security and performance standards.
  • Collaboration: Work closely with senior engineers to translate complex requirements into functional software.
Requirements:
  • 1-2 years of experience in C++ basics, up to and including C++23 (pointers, memory management, STL, and OOP principles).
  • AI-Native Workflow: Demonstrated experience using AI tools to solve coding challenges, refactor legacy code, or learn new libraries quickly.
  • Problem Solving: A solution-oriented mindset. You know how to use the tools at your disposal to find answers and build solutions.
  • Education: BS in Computer Science, Computer Engineering, or a related field (or equivalent practical experience).
  • Preferred Additional Skills:
  • Python Proficiency: Experience with Python for scripting, automation, or data manipulation is a major plus.
  • Modern Tooling: Familiarity with Git, CLion/VSCode, and CI/CD pipelines is a plus.
  • Local LLMs: Interest or experience in running local AI models or building custom RAG (Retrieval-Augmented Generation) implementations is a plus.
What we offer:
  • Work-Life Balance - no excessive overtime.
  • Competitive market-based pay with results based rewards.
  • Solid benefit package including 401(k), medical, dental, vision, and life insurance.
  • Generous time off including holidays and vacation.
  • Education Reimbursement.
  • Freedom to solve technical challenges.
  • Fully stocked break room, weekly lunches, volunteer opportunities, and more!

Permanent authorization to work in the U.S. is required. SG will not sponsor candidates for this position.
