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: 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. 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 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.
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 responsive React + TypeScript applications:



dashboards, campaign builders and reporting UIs
Performance & observability: optimize performance on both sides of the stack, debug complex issues and keep the system observable
Engineering standards: help shape engineering practices, code quality and architecture as we scale
5+ years of professional software engineering experience, with real work on both backend and frontend
~ Strong experience with TypeScript, Node.js and React
~ Solid understanding of modern API design, async workflows and web architectures
~ Experience with relational databases (PostgreSQL or similar)
~ Ability to work autonomously, debug complex issues and ship high-quality code
~ Strong communication skills and an advanced level of English
~ Temporal), distributed systems or microservices
Experience with Redis, Elasticsearch, Kafka or third-party API integrations
Knowledge of UI performance optimization or design systems
CI/CD practice with GitHub ActionsExperience in early‑stage or fast‑scaling startups
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.
Short Fridays all year round and extra days of vacation for your birthday and Geneversary.
Aticco office so you can work with stunning views an inspiring and energizing workspace.
