Developer Career Ladder

Design comprehensive engineering career ladders with clear competency frameworks, promotion criteria, and evidence templates.

Purpose

Create career ladders that:

• Define expectations for each engineering level
• Provide transparent promotion pathways
• Establish consistent evaluation criteria
• Guide career development conversations
• Support fair, evidence-based promotions

Competency Framework

Three Core Competencies:

1. Technical Excellence (varies by level)
2. Leadership & Influence (increases with level)
3. Collaboration & Impact (increases with level)

Senior Engineer (L5) Example:

{
  "level": "L5",
  "title": "Senior Engineer",
  "competencies": {
    "technical": {
      "weight": 0.60,
      "expectations": [
        "Designs and implements complex systems independently",
        "Makes sound architectural decisions for team's domain",
        "Debugs issues across stack/services",
        "Writes high-quality, maintainable code",
        "Considers scale, performance, reliability"
      ],
      "evidence_examples": [
        "Led migration to new database with zero downtime",
        "Designed caching layer that reduced latency 70%",
        "Implemented monitoring that caught 3 production issues before customer impact"
      ]
    },
    "leadership": {
      "weight": 0.25,
      "expectations": [
        "Mentors 2-3 junior/mid engineers",
        "Leads technical design for medium-large projects",
        "Influences technical decisions beyond own team",
        "Improves team processes and practices"
      ],
      "evidence_examples": [
        "Mentored 2 engineers who were promoted",
        "Led design review process improvement, reduced time 30%",
        "Presented technical deep-dive at engineering all-hands"
      ]
    },
    "collaboration": {
      "weight": 0.15,
      "expectations": [
        "Partners effectively with PM, design, data",
        "Communicates technical concepts to non-technical stakeholders",
        "Drives consensus on technical decisions",
        "Contributes to engineering culture"
      ],
      "evidence_examples": [
        "Led cross-functional project with PM and design",
        "Wrote technical blog post (external or internal)",
        "Organized engineering book club"
      ]
    }
  }
}
