Attracting top developers in 2025 requires competitive pay, remote flexibility, and AI-savvy teams. A small set of companies achieve both high talent density and scalable retention. Google, Netflix, Apple, Microsoft, and Amazon lead in retention, while Anthropic, OpenAI, and Meta grow engineering teams faster than losses; Tesla, Bloomberg, and Walmart lose talent faster than hiring. Engineer-to-manager ratios increased 30% over nine years, enabling greater individual impact. Four-year tenure dipped slightly, countering job-hopper narratives. Significant shares of engineers at major firms lack college degrees, demonstrating skill-based hiring paths. FAANG success traces to elite hiring, retention, and sustainable growth.
In 2025, attracting top developers is more challenging than ever. A competitive pay package is table stakes, remote flexibility is expected, and AI is reshaping how teams operate and what engineers value. College isn't necessary for big tech jobs SignalFire's data reveals a new reality: a handful of companies have cracked the code to build cultures where top engineers flock to, stay, grow, and multiply their impact. These outliers have achieved something rare: both high talent density and high retention, at scale.
Key takeaways from this report: Retention leaders: Google, Netflix, Apple, Microsoft, and Amazon set the standard for keeping top engineering talent. Attrition winners and losers: Anthropic, OpenAI, and Meta are growing engineering teams 2-3x faster than they're losing them, while Tesla, Bloomberg, and Walmart are losing talent faster than they can hire. Fewer managers, bigger impact: Over nine years, the engineer-to-manager ratio rose 30% (from 5.87 to 7.65) thanks to better tools and more autonomous teams.
Tenure is steady: Four-year tenures dipped only slightly (59% 52%), challenging the job-hopper myth. Pedigree isn't required: A college degree isn't required for big tech jobs. At Microsoft, Adobe, and Walmart, 15%+ of engineers lack degrees; Disney, Netflix, and Apple follow at 13%, proving skills and experience can open doors without diplomas.
