What are Mid Level Developers?

Mid Level Developers are software professionals who have gained several years of experience beyond entry-level positions and are proficient in coding, debugging, and collaborating on projects. They possess a strong understanding of programming languages, frameworks, and software development processes. Mid Level Developers often take on more responsibility than junior developers, such as mentoring newer team members, contributing to architectural decisions, and ensuring code quality. They are expected to work independently on tasks, communicate effectively with team members, and deliver reliable solutions to complex problems.

What is the difference between Mid Level Developer vs Junior Developer?

The main difference between a Mid Level Developer and a Junior Developer lies in experience, skill proficiency, and responsibilities. Mid Level Developers have more experience, can handle complex tasks independently, and contribute significantly to projects, whereas Junior Developers are still learning foundational skills and typically work under supervision.

What are the key skills and qualifications needed to thrive as a Mid Level Developer, and why are they important?

To thrive as a Mid Level Developer, you need solid programming skills in languages such as Java, Python, or JavaScript, along with a relevant degree or equivalent experience. Familiarity with version control systems like Git, integrated development environments (IDEs), and frameworks such as React or Spring Boot is typically required. Effective problem-solving, teamwork, and strong communication skills help you collaborate and adapt to project needs. These abilities ensure you can deliver reliable code, work smoothly with colleagues, and contribute to successful software projects.

What opportunities for professional growth can a Mid Level Developer typically expect within a software development team?

As a Mid Level Developer, you can expect to take on more complex projects, mentor junior team members, and gradually assume greater ownership of features or modules. Many organizations support growth through peer code reviews, access to learning resources, and the chance to participate in architectural discussions. Advancement paths often include moving toward senior developer roles, technical leads, or specializing in areas like DevOps or security, depending on your interests and the company's needs.

We are looking for experienced Mid-level (Full Stack, Backend, Frontend) Engineers passionate about building an excellent user experience up and down the layers of an application.

An experienced Mid-level Engineer at Perpay will spend their time writing code, reviewing PRs, and helping scope & design new features.

We aim for our Engineering team to be a place that Mid-level Engineers can push our quick-growing startup forward, and grow into future Senior Engineers and Engineering leaders. The significant projects and initiatives available to our Mid-level Engineers provide opportunities to expand experience, ownership, and business value.

Our greatest strength is our people and we'd love for you to be one of them!

Responsibilities:
  • Collaborate closely with the development team, including UX designers, product managers, and other Engineers, to implement solutions that meet business needs and provide the best user experience
  • Work with stakeholders to design, build, test, and release new features for our platform
  • Write clean, efficient, and maintainable code. Break down code contributions into reviewable, shippable chunks
  • Contribute to the Engineering design process by bringing forward tradeoffs and opinions
  • Identify opportunities to reduce technical debt and implement changes to improve developer experience and team velocity
  • Participate independently in on-call rotation and coordinate incident response
What You'll Bring:
  • Minimum of 2 years experience as a Software Engineer (excluding internships or coop experiences) with a focus on full stack development
  • Strong proficiency in at least one backend application framework such as Django or Flask and experience with frontend technologies such as React, Angular, or Vue.js
  • Proven experience building, deploying and maintaining scalable web applications, with knowledge of database design and management
  • Knowledge of RESTful API design and integration
  • Experience working with cloud infrastructure and containerization technologies such as AWS, Docker, and Kubernetes is preferred
  • Passion for learning new technologies and keeping up with industry trends
  • Ability to collaborate with cross-functional teams, including UX designers, product managers, and other Engineers
  • Strong communication skills and ability to articulate technical concepts to non-technical stakeholders
