Showing 5 of 17+ Junior Software Developer jobs
This role is for a junior developer who is comfortable using AI coding tools (GitHub Copilot, Cursor, Claude Code, OpenAI Codex, or similar) as a core part of the development workflow, not as a replacement for engineering judgment. In 2026, junior developer expectations have shifted from writing code line-by-line toward owning small features end-to-end, reviewing AI-generated code for correctness and security, and knowing when to accept, modify, or reject AI suggestions. The company is a small, agile team building SaaS/web applications and automation tools, and this position will work closely with technical leadership on hands-on implementation.
Responsibilities
- Build and maintain features for web applications and internal tools using modern frameworks (JavaScript/TypeScript, Python)
- Use AI-assisted development tools (Copilot, Cursor, Claude Code, ChatGPT/Codex) to accelerate coding, debugging, and documentation, while critically reviewing all AI-generated output for logic, security, and performance issues
- Integrate third-party and AI/LLM APIs (OpenAI, Anthropic, etc.) into applications and automation workflows
- Write clean, tested, version-controlled code using Git/GitHub, including participation in code reviews and pull requests
- Assist in designing and implementing database schemas and SQL queries
- Support deployment pipelines and basic cloud infrastructure tasks (AWS, Azure, or similar)
- Participate in agile ceremonies (standups, sprint planning, retrospectives) and document processes and system changes
- Troubleshoot and resolve bugs, collaborating with senior developers to refine requirements
Required Qualifications
- 1–3 years of professional or project-based experience in software/web development (internships, bootcamps, and self-directed projects are accepted)
- Practical experience with at least one core language: JavaScript/TypeScript or Python
- Working familiarity with AI-assisted coding tools (GitHub Copilot, Cursor, Claude Code, ChatGPT/Codex) and the ability to critically evaluate AI-generated code rather than accept it uncritically
- Basic understanding of web development fundamentals (HTML/CSS, REST APIs, a modern frontend framework such as React or Next.js)
- Familiarity with SQL and relational databases
- Experience with Git/GitHub version control
- Strong problem-solving skills and eagerness to learn quickly in a fast-moving, AI-augmented environment
- Proficient with Linux and Windows OS
Preferred Qualifications
- Exposure to cloud platforms (AWS, Azure, or GCP)
- Experience integrating LLM/AI APIs (OpenAI, Anthropic Claude) into applications or automation workflows
- A portfolio of 2–3 deployed personal or bootcamp projects demonstrating practical use of AI coding tools, with documented READMEs
- Bachelor’s degree in computer science or related field, or equivalent practical/self-taught experience
- Basic security awareness — understanding of common vulnerabilities and secure coding practices

Junior Software Developer Jobs in California: Frequently Asked Questions
How do you become a junior software developer in California?
California does not require a state-issued license to work as a software developer, so the path runs through education and demonstrated skills. Most employers expect a bachelor's degree in computer science or a related field, though many California companies also hire graduates of accredited coding bootcamps. Building a portfolio of personal or open-source projects is often the deciding factor for candidates without professional experience.
How much do junior software developers make in California?
Junior software developers in California earn a median of about $174,410 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $105,060 for the lowest 10% to over $272,670 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire junior software developers in California?
Employers hiring junior software developers in California right now include Canonical, SAIC, and Arvato, based on current listings on Migrate Mate as of September 2026. California's density of technology headquarters means junior developers here often have access to large engineering teams and structured onboarding programs that are less common in other states.
Which California cities have the most junior software developer jobs?
Los Angeles, Mountain View, and Norco have the most junior software developer openings in California. San Francisco and its surrounding Bay Area communities lead because of the concentration of technology headquarters there, while Los Angeles has grown rapidly in entertainment technology and fintech, and San Diego draws from a strong defense-tech and biotech sector that increasingly relies on software talent.
Are there remote junior software developer jobs in California?
Yes, and more than most fields. About 91% of junior software developer openings tied to California are remote or hybrid as of September 2026, reflecting how naturally the work translates to distributed teams. Backend and frontend web development roles tend to have the highest share of fully remote positions, while roles requiring hardware integration or on-site collaboration with product teams are more likely to require in-person presence.
How can I get hired as a junior software developer in California with little or no experience?
The most realistic entry path is through a structured new-graduate or apprenticeship program at a large California employer. Companies like Google, Apple, and Salesforce run formal early-career engineering programs designed for candidates without professional experience. Contributing to open-source projects, completing a California-based coding bootcamp, or moving laterally from a QA analyst or technical support role are common ways candidates build the portfolio that opens junior developer doors.
