Join one of Southern Europe's fastest-growing startupsEnginy is a Barcelona-based startup and one of Southern Europe's fastest-growing companies ranked #3 in the Sifted 100: We're building the AI-native GTM platform for modern B2 B teams, combining prospecting, enrichment, intent signals, AI research and outreach into one product so sales teams can focus on what truly matters: selling. That means more users, more data, more integrations and harder engineering problems exactly the stage where strong engineers have an outsized impact.
As a Fullstack Engineer, you'll have real ownership from day one across the whole product: high-throughput backend workflows, integrations, AI-powered features and polished web experiences. You'll own meaningful problems end to end and help shape both the product and the engineering standards of a company entering its next stage of growth.

About the role

No trivia-heavy interviews and no artificial take-home exercises we focus on how you think through product problems, technical trade-offs, ambiguity, quality, and the use of AI as part of modern engineering.
One of our tech leads wrote about the philosophy behind it here: Enticing performance bonuses that you won't see anywhere else.
