What is a mid backend developer?

Mid Backend Developers are software engineers with intermediate experience who focus on building, maintaining, and optimizing the server-side components of web or mobile applications. They typically work with databases, APIs, server logic, and integration with front-end systems. Mid-level developers have a solid understanding of programming languages such as Java, Python, Node.js, or Ruby and are expected to contribute to code reviews, troubleshoot issues, and implement new features under minimal supervision. Their role bridges the gap between junior developers, who need more guidance, and senior developers, who handle architecture and high-level decisions.

What are the key skills and qualifications needed to thrive as a mid backend developer, and why are they important?

To excel as a Mid Backend Developer, you need strong programming skills in languages such as Java, Python, or Node.js, along with a solid understanding of databases and API design, typically backed by a bachelor’s degree in computer science or related field. Familiarity with tools and systems like Git, RESTful APIs, Docker, and cloud platforms (e.g., AWS, Azure) is usually required. Problem-solving abilities, effective communication, and teamwork are crucial soft skills that set high performers apart. These competencies ensure efficient development, maintainability, and seamless integration of backend services in dynamic technical environments.

What are some typical challenges a mid backend developer might face when integrating new technologies into existing systems?

As a Mid Backend Developer, one common challenge is ensuring that new technologies or frameworks integrate smoothly with legacy systems without disrupting current operations. This often involves understanding both the old and new codebases, data migration, and dealing with compatibility issues. Collaborating closely with frontend developers, DevOps, and QA teams is essential to address potential bottlenecks and maintain performance. Additionally, thorough testing and documentation are crucial to ensure long-term stability and maintainability.

Member of Technical Staff (Software Engineer, Backend Platform)

Perplexity

New York, NY • On-site

$220K - $405K/yr

Full-time

Job description

About the Role
The Backend Platform team is the backbone of Perplexity's product reliability, scalability, and performance, enabling every product and AI team to build with confidence.
This high‑impact group builds and maintains critical infrastructure, including backend systems for authentication, authorization, real-time data flows, service orchestration, and sandboxing, to ensure fast, reliable, and secure user experiences. By setting rigorous standards for code quality, uptime and performance, the Platform team ensures everyone at Perplexity can innovate at speed on top of a robust, well-architected foundation.
Key Responsibilities
  • Lead the design and implementation of our sandboxing platform to safely execute untrusted and user‑generated code while meeting strict performance and reliability requirements.
  • Define and extend our RBAC and authorization primitives, ensuring they scale with new product capabilities and enterprise controls.
  • Own key backend services involved in authentication and encryption flows (including BYOK‑related pieces), partnering with Security and Infra on defense‑in‑depth.
  • Set the technical bar for backend platform design and operations, driving best practices in reliability, observability, and incident response for always‑on systems.
  • Partner with product and AI teams to define clear platform interfaces, SLAs, and integration patterns so new features can reliably build on shared backend capabilities.
  • Provide technical leadership across the backend platform area, mentoring other engineers and making long‑term architectural decisions that keep the foundation simple, secure, and evolvable.

Qualifications
  • Experience designing and building backend systems that run in production (typically 4+ years for mid-level, more for senior and staff).
  • Strong system design skills, with a track record of creating efficient, reliable, and scalable architectures.
  • Hands-on experience with modern infrastructure (for example AWS, Kubernetes, and related cloud technologies).
  • Strong proficiency in at least one backend language such as Python, Go, or Rust, and the ability to work effectively in a multi-language environment.
  • Collaborative mindset and eagerness to solve challenging technical problems with other experienced engineers.
  • Comfort working in security‑sensitive areas (auth, authorization, encryption) and making pragmatic trade-offs between safety, simplicity, and velocity.

If you're excited about this role, we encourage you to apply even if your experience doesn't match every qualification listed above.
