Staff Engineer (Hybrid)

We’re looking for a Staff Software Engineer to join our client, a fast-scaling technology company building products used by millions of users globally. This is a senior hands-on engineering role for someone who thrives on solving complex problems, shaping architecture, and leading by example—not just following predefined blueprints. You’ll work across the stack with PHP, Node.js, and React, designing and delivering high-performance systems in a fast-paced, product-driven environment.

Lead the design, development, and evolution of large-scale web applications serving high user volumes

Collaborate closely with product and engineering teams to define architecture, APIs, and system patterns

Set standards for code quality, performance, and scalability across backend and frontend systems

Mentor engineers, providing guidance on technical decisions and long-term architectural direction

Work across the stack—designing backend services in PHP / Node.js and building intuitive, performant React frontends

Optimize system performance, reliability, and user experience for large-scale, data-driven applications

8+ years of professional software engineering experience

~ Strong experience with PHP and Node.js on the backend and React on the frontend

~ Hands-on experience with relational and NoSQL databases (e.g. MySQL, PostgreSQL, MongoDB)

~ Familiarity with modern DevOps and CI / CD practices in cloud-based environments (AWS, GCP, or Azure)

~ Experience leading technical initiatives or acting as a key decision-maker in engineering teams

Knowledge of caching, scaling, and performance tuning for web-scale applications

Exposure to microservices architectures, containerization (Docker, Kubernetes), or serverless technologies

Familiarity with analytics, A / B testing, and data-driven product iteration

You’ll join a collaborative, forward-thinking engineering culture that values autonomy, technical depth, and creative problem-solving.

The role is hybrid or remote within Europe, and requires eligibility to work in the region without sponsorship.
