Join one of Southern Europe's fastest-growing startups

Enginy is a Barcelona-based startup and one of Southern Europe's fastest-growing companies ranked #3 in the Sifted 100: Southern Europe 2026, and we're just getting started.

We're building the AI-native GTM platform for modern B2B teams, combining prospecting, enrichment, intent signals, AI research and outreach into one product so sales teams can focus on what truly matters: selling. No wasted time, just results.

After raising a €5M seed round, we're scaling internationally and growing the team behind the product. 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.

If you enjoy shipping fast,



making product and technical decisions, and seeing your work directly impact customers, you'll have plenty of room to make a difference here.

About the role

We're looking for an engineer who is comfortable anywhere in the stack from a Temporal workflow to a React component and who wants to own features from the first conversation with Product to production.

You'll join early enough to shape the systems, standards and product, at a stage where scale and customer demand already create real engineering challenges.

Problem → API → UI → ship → iterate

What you'll own

• End-to-end features: ship complete functionality across backend and frontend, with a clear focus on quality, reliability and speed

• Backend services: build scalable services, async workflows and data pipelines (Temporal), plus production-grade APIs and integrations with CRMs, LinkedIn and more

• Web product: develop r
