Enginy AI is a Barcelona-based startup ranked #3 in Sifted 100: Southern Europe 2026, building an AI-native GTM platform for B2B sales teams. The platform combines prospecting, enrichment, intent signals, AI research, and outreach into a single product. After raising a €5M seed round, the company is scaling internationally and growing its engineering team.
As a Senior Frontend Engineer, you will own the customer-facing experiences that power the platform: dashboards, campaign builders, and reporting UIs. You'll work closely with Product and Design teams to shape how the frontend scales as the company grows. The role focuses on building high-quality, performant web applications that make complex functionality feel simple and intuitive.
Key responsibilities include:
- Developing high-quality, responsive web applications using React and TypeScript
- Owning core UIs: dashboards, campaign builders, reporting interfaces, and supporting API layers
- Working on internal tools, SSR/edge rendering, and lightweight Node.js services
- Optimizing for performance, Core Web Vitals, and developer experience
- Delivering features end-to-end from conception through measurement, collaborating with Product, Design, and Backend teams
- Helping establish frontend practices, code quality standards, and architecture as the company scales
The company emphasizes a hiring process focused on real engineering work: realistic product and technical problem-solving, not trivia. The interview includes an intro conversation, a practical task using a small version of the product (with AI tools encouraged), a technical/product conversation, and a final team-fit discussion.
The office is located at Aticco with stunning views and an inspiring workspace. The company offers continuous learning opportunities, career growth, team gatherings, and a collaborative culture emphasizing transparency and open communication.
REQUIREMENTS:
- 5+ years of professional software engineering experience with strong frontend focus
- Strong experience with TypeScript and React
- Solid understanding of modern web architectures and frontend-to-API communication
- Ability to work autonomously, debug complex issues, and ship high-quality code
- Product and design sensibility; care about how things feel, not just how they work
- Strong communication skills and advanced English proficiency
- Bias for action and ownership; thrive in fast-moving startup environments
NICE TO HAVE:
- Knowledge of UI performance optimization, design systems, or a11y testing
- Experience with SSR/edge rendering and Node.js
- Basic backend exposure and relational database knowledge (PostgreSQL or similar)
- CI/CD practice with GitHub Actions
- Experience in early-stage or fast-scaling startups
- Interest in B2B SaaS, sales tech, or automation tools
