What does an entry level software engineer do?

An entry level software engineer is responsible for assisting in the design, development, testing, and maintenance of software applications. They typically work under the guidance of more experienced engineers and may write code, debug programs, and participate in code reviews. The role often involves learning company-specific tools and workflows, collaborating with team members, and continuously improving technical skills. Entry level software engineers are expected to adapt quickly, communicate effectively, and contribute to the team's overall goals.

What does an entry level software engineer do?

An Entry-Level Software Engineer, also called a Junior Engineer, works with a team of mid-level and senior engineers to develop, test, and maintain software applications and programs. The job duties of Junior Software Engineers typically include relatively simple routine tasks, such as debugging, testing, and code documentation. These tasks hone a Junior Engineer’s skills and familiarize them with the company’s code base. As Software Engineers gain more years of experience, they work on more complex development projects.

What are the key skills and qualifications needed to thrive as an entry level software engineer, and why are they important?

To thrive as an Entry Level Software Engineer, you need a solid understanding of programming languages (such as Java, Python, or C++), computer science fundamentals, and often a relevant bachelor’s degree. Familiarity with version control systems like Git, development frameworks, and basic software development tools is typically expected. Strong problem-solving abilities, eagerness to learn, and effective collaboration are standout soft skills in this role. These skills are crucial for building reliable software, adapting to evolving technologies, and contributing productively to team projects.

What types of projects do entry level software engineers typically work on, and how do they collaborate with other team members?

Entry level software engineers often start by working on smaller features, bug fixes, or assisting with testing and documentation within larger projects. They usually collaborate closely with senior engineers, product managers, and QA teams through code reviews, daily stand-ups, and pair programming sessions. This structure helps new engineers learn best practices, understand the codebase, and gradually take on more complex assignments. Effective communication and a willingness to learn are key to success in these collaborative environments.

What is the difference between Entry Level Software Engineer vs Software Developer?

AspectEntry Level Software EngineerSoftware Developer
Required CredentialsBachelor's in CS or related field; some internshipsBachelor's in CS or related; coding experience
Work EnvironmentTeam-based, collaborative projects, entry-level tasksProject-focused, coding, debugging, and implementation
Employer & Industry UsageTech companies, startups, IT departmentsSoftware firms, tech startups, enterprise IT
Common Search & ComparisonYesYes

Entry Level Software Engineers and Software Developers often share similar educational backgrounds and work environments. The main difference lies in their roles: engineers may focus more on designing systems and architecture, while developers typically concentrate on coding and implementation. Both roles are essential in tech industries and often overlap in job functions, but understanding these distinctions helps job seekers target the right positions.

Is 25 too late to become an entry level software engineer?

Entry level software engineering roles are open to candidates of all ages, and starting at 25 is common. Many employers value skills, such as programming languages and problem-solving abilities, over age, and individuals can transition into the field through coding bootcamps, online courses, or degree programs. Age should not be a barrier to entering an entry level software engineering position.

  • Work closely with GNC, embedded, systems, and hardware engineers to integrate software with complex electromechanical systems.
  • Optimize software for real-time execution, low-latency performance, and resource-constrained embedded platforms.
  • Build simulation, testing, and development infrastructure to accelerate software development and validate system performance.
  • Debug and troubleshoot complex software and hardware-software integration issues.
  • Develop automated tests and contribute to CI/CD pipelines to improve software quality and development velocity.
  • Contribute to software architecture and technical design decisions as systems evolve.
  • Identify opportunities to improve system performance, reliability, and developer productivity, and drive solutions from concept through implementation.
  • Communicate technical challenges, risks, and tradeoffs clearly across a highly cross-functional engineering team.

Required Qualifications
  • Experience implementing a substantial software project, such as a capstone, research project, internship project, student design team, or personal project.
  • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field.
  • Graduating with a bachelor's degree, master's degree or PhD in 2026 or 2027
  • Proficiency in C++, Rust, Python, or C, with the ability to write clean, well-tested, and efficient code.
Preferred Qualifications
  • Experience developing software for autonomous systems, robotics, aerospace, or other complex electromechanical systems..
  • Experience with embedded systems, microcontrollers, or RTOS environments.
  • Familiarity with GNC, controls, state estimation, sensor fusion, or robotics.
  • Experience building simulation environments or software-in-the-loop / hardware-in-the-loop testing infrastructure.
  • Experience working with sensors, actuators, communication interfaces, or other hardware interfaces.
  • Familiarity with Linux, networking, concurrency, or distributed systems.
  • Experience with CI/CD, automated testing, and software development infrastructure.
  • Experience working on rocketry, UAVs, robotics, autonomous vehicles, or other student engineering projects.
