Project mention: Contrarian View: You Should Stay at Your Job for 5+ Years – 2026 Stripe Data | dev.to | 2026-04-28
Stripe’s 2026 data shows that 5+ year engineers ship 2x more core infrastructure projects than job-hoppers, which is the primary driver of Staff+ promotions. Core infrastructure (payments processing, fraud detection, regulatory compliance systems) has high switching costs: it takes 6-12 months to ramp up on a system that processes billions of dollars in transactions, and most job-hoppers leave before they can ship meaningful changes. To build deep context: volunteer for on-call rotations for core systems, document edge cases you encounter, and contribute to internal tooling for the core stack. Use open-source SDKs like Stripe Go SDK to practice integrating with payments infra, even if you work at a different company. Deep context makes you indispensable: Stripe’s 5+ year core infra engineers report 0% involuntary turnover, compared to 12% for job-hoppers. This leverage also lets you negotiate higher raises: Stripe’s 2026 comp data shows that engineers with deep core infra context get 15-20% higher base salary increases than peers with similar performance. Remember: you can learn a new JavaScript framework in 2 weeks, but it takes 5+ years to understand why a payments system retries failed API calls 3 times with exponential backoff instead of 5. That context is what separates Staff+ engineers from senior engineers.
