Opis stanowiska
1. Job Purpose
We are a fast-growing tech company with a portfolio of SaaS products serving diverse industries. Innovation, performance, and design precision are core to our values. As we scale, we are looking for a talented Senior FullStack Developer to join our team and take a key role in crafting highly performant, maintainable, and user-focused web applications.
2. Key Responsibilities
• Contribute to both backend (NestJS) and frontend (NextJS) systems by designing and building scalable, secure, and maintainable features, while leading architecture decisions across services, APIs, and cross-stack boundaries.
• Champion clean code, modular design, and testability through active contribution, reusable components, and mentoring.
• Drive system-level decisions around performance, observability, and scalability, and ensure alignment between product goals and technical implementation.
• Own and enforce code quality via reviews, maintain CI/CD reliability, and collaborate closely with DevOps to ensure release stability and consistent environments.
• Monitor and optimize system performance, define logging and alerting standards, and lead incident response and continuous improvement efforts.
• Work closely with product, QA, and designers to unblock delivery, while mentoring engineers and fostering technical alignment across squads.
3. Required Skills & Qualifications
Experience:
• 5+ years of fullstack development experience; NestJS, Node.js, NextJS, and TypeScript
• Strong understanding of PostgreSQL, data modeling, and optimization techniques
• Solid experience building and consuming REST with secure JWT-based auth flows
• Proven ability to lead architecture decisions, enforce code quality, and guide teams through technical complexity
• Familiarity with CI/CD pipelines, Docker, and environment management (bonus: K8s, ArgoCD)
• Experience with frontend performance optimization (SSR, lazy loading, state management)
• Comfortable working in cross-functional squads with product, QA, and design
• Good communication skills
Nice to Have:
• Experience with component libraries (e.g., Storybook, React UI) or design systems
• Exposure to event-driven systems using tools like Kafka, RabbitMQ, or AWS SNS/SQS
• Knowledge of Infrastructure as Code (Terraform)
• Background in observability tooling (e.g., Sentry, Datadog, Groundcover) and defining alerting/logging standards
• Contributions to internal platforms, shared packages, or developer experience tools
Soft Skills
• Clear written and async communication, especially in distributed teams
• Systemic thinking — sees the bigger picture across stack, squads, and product
• Ownership mindset, from design to delivery to incident resolution
• Pragmatic decision-making, balancing trade-offs in real-world scenarios
4. Key Performance Indicators (KPIs)
• End-to-end feature delivery reliability
• Architecture quality and system scalability
• Code review throughput and mentorship impact
• Production stability and issue resolution time
• Documentation, testing, and developer experience
5. What We Offer
• Competitive compensation
• 22 paid vacation days + local national holidays
• Annual learning & development budget
• Opportunity to impact a fast-growing multi-product company
• Cross-functional projects, modern stack, and zero legacy burden
