Job description

// About the Role

We are looking for a Senior Full-Stack Engineer to join our core engineering team in Amsterdam. You will design, build, and ship production-grade platforms for enterprise clients, from database schema and API design to polished, high-performance UIs.

At Sanera, engineers own features end-to-end. You will work directly with clients, shape technical architecture, and mentor junior developers. We move fast, ship often, and care deeply about craft.

// Responsibilities

• Design and implement full-stack features across React/Next.js frontends and Node.js/Python backends.
• Architect scalable systems: data models, APIs, real-time pipelines, and cloud infrastructure.
• Collaborate with design and product to translate requirements into clean, maintainable code.
• Write tests, set up CI/CD pipelines, and maintain production reliability.
• Participate in code reviews and help raise the engineering bar across the team.
• Communicate directly with clients to understand their systems and deliver solutions.

// Requirements

• 5+ years of professional software engineering experience.
• Strong proficiency in TypeScript, React, and Node.js . Experience with Next.js is a plus.
• Solid understanding of relational databases (PostgreSQL), REST/GraphQL APIs, and cloud services (AWS or GCP).
• Experience with containerization (Docker) and CI/CD workflows.
• Ability to work autonomously, manage your own priorities, and communicate clearly in English.

// Nice to Have

• Experience building CRM integrations or enterprise SaaS platforms.
• Familiarity with AI/ML tooling: embeddings, vector databases, LLM APIs.
• Background in performance optimization, caching, or real-time systems.
• Open-source contributions or a portfolio of shipped side projects.

// What We Offer

• Competitive salary with equity participation for senior roles.
• Hybrid work model: Amsterdam office with flexible remote days.
• Direct impact: small team, big clients, real ownership.
• Modern tooling, fast feedback loops, and a culture that values shipping over meetings.
• Learning budget and conference attendance support.
