JavaScript Engineer - Hybrid Porto

ABOUT THE OPPORTUNITY

Join a well-established, internationally operating custom software solutions company with over 40 years of proven delivery excellence. With engineering hubs across 7 cities and a reputation for attracting top-tier talent, this organisation has mastered distributed development without sacrificing team culture or quality.

This is not a siloed role. You'll be embedded in cross-functional, diverse project teams working on meaningful, real-world challenges across a wide range of industries. The environment is collaborative, the structure is flat, and career growth is actively supported — not just promised.

This position is based out of the Porto hub, operating on a hybrid model. The hub is a space for knowledge sharing, collaboration, and culture — with catered lunches, great coffee, and regular social and cultural events.

PROJECT & CONTEXT

As a JavaScript Engineer, you will contribute to the full development lifecycle of complex, client-facing web applications built on modern JavaScript frameworks. You'll work alongside back-end engineers, architects, and product designers to deliver high-quality, testable, and maintainable front-end solutions integrated with REST-based services.

Your day-to-day will include analysing and understanding requirements, identifying and resolving production and non-production issues, ensuring specifications are met, and actively contributing to continuous improvement of the software delivery process. You'll be expected to stay current with evolving technologies, methodologies, and best practices — and share that knowledge with your team.

This role offers genuine scope for engineers who want to grow technically, contribute architecturally, and be recognised for exceptional performance through structured awards, peer shoutouts, and performance-based bonuses.
