Overview

Mid-Level Developers work independently on defined tasks, following established patterns and standards. They can focus on either Lightning Web Components (LWC) or Apex, with strong skills in their primary area. They should be building skills in the other language/framework with guidance from developers who have expertise in that area. Having understanding in both is an added benefit, and they can implement features end-to-end with minimal guidance in their primary focus area.

Quick Facts

  • Code Involvement: 85-90% (Independent development)
  • Typical Experience: 2-4 years
  • Decision Authority: Implementation details within story scope
  • Focus Area: Independent development, following standards

Core Responsibilities

  • Implement features independently following established patterns in primary focus area (LWC or Apex)
  • Write clean, maintainable code in primary focus area (Apex OR Lightning Web Components)
  • Build skills in secondary language/framework with guidance from developers with expertise in that area
  • Write comprehensive unit tests meeting coverage requirements
  • Participate actively in code reviews (both giving and receiving)
  • Follow and enforce coding standards and best practices
  • Document code appropriately with JSDoc/ApexDoc
  • Debug and troubleshoot issues independently in primary focus area
  • Estimate story points for assigned features
  • Collaborate with team members on feature implementation
  • Assist Junior Developers with questions and guidance

Required Skills & Experience

Technical Skills

Primary Focus (strong skills in one):

  • Apex Developer Path: Strong Apex development skills
  • LWC Developer Path: Strong Lightning Web Component development skills

Secondary Skills (developing with guidance):

  • Bug fixes and enhancements
  • Code reviews and feedback
  • Technical documentation
  • Estimates and task breakdowns

Decision Authority

  • Implementation details within story scope
  • Code structure and organization (following standards)
  • Test approach and test data setup
  • Code refactoring within assigned features

Mentorship & Collaboration

  • Provides guidance to Junior Developers
  • Collaborates with Senior Developers on complex features

  • Independence and self-sufficiency
  • Collaboration and communication effectiveness
  • Problem-solving ability

Quantitative

  • Delivery velocity (story points per sprint)
  • Test coverage (target: 80%+)
  • Code review feedback quality
  • Bug introduction rate (should be low)
  • On-time delivery rate

Career Progression

Path From

  • Junior Developer (typically 1-2 years)
  • Developer from another platform with Salesforce training

Path To
