Software Development San Francisco, California 11–50 employees Founded 2014 Privately Held

Tenjin operates a mobile marketing analytics platform serving 30,000+ apps through a fixed $200/month model. The engineering-led org (12 of 13 hires are senior-level) is executing a major backend migration from Ruby to Go while simultaneously scaling real-time analytics and high-volume data ingestion — a trio of challenges that explains both the tech-stack shape (Rails + Sidekiq legacy, Go adoption) and the hiring velocity (accelerating, concentrated in senior engineering roles across seven countries).
