Senior Full Stack Software Engineer (Node.js & React)

We are seeking a highly autonomous Senior Full Stack Engineer to drive architectural excellence across our digital ecosystem. You will own end-to-end technical solutions, designing secure, scalable, and reliable services. Acting as a core pillar of our Platform Engineering team, your mission is to refactor fragmented product capabilities into a centralized, event-driven platform hosted on GCP. We rely on your system-level thinking to eliminate technical debt, ensure production stability, and accelerate time-to-market.

• End-to-End Solution Ownership: Architect, build, and deploy secure, scalable, and reliable features, taking accountability from database schema design through to UI delivery
• Platform Refactoring & IAM: Extract complex business logic from four monolithic products into centralized, reusable platform services. Implement robust tenant onboarding and authorization via Auth0
• Technical Leadership & Alignment: Collaborate closely with Product and Design to translate business requirements into technical reality. Drive engineering standards through technical design docs (RFCs), rigorous code reviews, and team mentorship
• Operational Excellence: Build for "day-two" operations. Instrument applications with robust logging, metrics, and monitoring (utilizing GCP-native or agnostic observability tools) to proactively identify bottlenecks and ensure system reliability.

We require an expert capable of navigating the entire stack with a strong emphasis on modern cloud infrastructure and automated quality.

• Core Languages & Frameworks: Expert proficiency in TypeScript across both client and server. Deep experience with React and Next.js, alongside advanced server-side engineering using Node.js
• API & Data: Proven ability to design and maintain secure REST APIs and GraphQL services. Deep hands-on experience with Postgres databases (relational design, migrations, query optimization)
• Cloud & DevOps: Deployment and operational experience on GCP (Google Cloud Platform). Hands-on fluency with GitHub and GitHub Actions for robust CI/CD pipelines.

Job Requirements

• Proven Track Record: 5+ years of full-stack engineering with a demonstrated history of operating at a senior, highly autonomous level
• System-Level Thinking & EDA: Practical experience with distributed systems, event-driven architectures, asynchronous messaging, and transitioning monoliths to decoupled services
• Quality Mandate: Uncompromising commitment to high-quality code, automated testing strategies (unit, integration, E2E), and secure software development lifecycles (SSDLC)
• Problem Solving: Exceptional analytical skills with the ability to foresee edge cases, understand cross-system dependencies, and architect for long-term maintainability.

What we offer? You will find here not only a challenging and interesting workplace, but also a rewarding work experience, with competitive compensation and benefit packages:

• A dynamic and multinational environment with dedicated professionals who are ready to share their knowledge with you
• Soft skills and technical training for current and emerging products and technologies
• Career development: opportunity to grow within the team
• Special referral bonuses for recommending your friends
• Private Medical subscription
• Meal tickets
• Extra vacation days
• Flexible working hours and work from home, aligned with project needs
• Friendly team who is eager to meet you.
