What is a mid level developer?

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?

Work EnvironmentIndependent work, team collaboration, project ownership

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?

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.

Job description

Company Overview
Most companies don't end in acquisition - they end in closure. Yet shutdown has never been given the same rigor, clarity, or professionalism as the moments that came before it. Nearly 4 million companies shut down every year, creating a massive, overlooked market. SimpleClosure is building the infrastructure to change that.
Having raised over $20M from leading VCs and trusted by more than 7,000 companies to date, we streamline the entire business dissolution process - from legal and tax to operational and administrative - as one coordinated effort instead of a patchwork of disconnected steps. We take it a step further by connecting founders with buyers for their remaining assets, so they can realize value that would otherwise be lost.
Joining SimpleClosure means helping define an entirely new category, solving complex, high-impact problems, and building the products and processes that support founders through one of the most important moments in a company's journey.

  • Write high-quality, well-tested code and participate in code reviews
  • Own features end-to-end, from technical design through deployment and iteration
  • Debug, troubleshoot, and resolve issues in production environments
  • Continuously improve development processes, tooling, and code quality

Desired Skills & Qualifications
  • Experience: 3-5 years of professional software engineering experience, ideally in a startup or fast-paced environment
  • Frontend: Strong experience with React and TypeScript; Next.js or similar frameworks preferred
  • Backend: Experience building server-side logic, APIs and integrating with third party services
  • Databases: Familiarity with relational and/or NoSQL databases
  • Ownership: Comfortable taking projects from concept through deployment and iteration
  • Problem-Solving: Proactive, thoughtful engineer who can navigate ambiguity and make sound technical decisions
  • Collaboration: Strong team player who enjoys working cross-functionally
  • Communication: Clear written and verbal communication skills
  • Adaptability: Thrives in an evolving startup environment with shifting priorities

What we offer
  • Base Salary: $120,000 - $170,000, depending on experience level
