Senior Full-Stack Engineer (Back-End-Leaning) — Lead, Amplify Platform

Saga is a legal innovation company on a mission to remove the friction between legal expertise and real-world impact, so lawyers can focus on what matters the most: people, ethics, and impact. Founded in Norway and built for the legal profession from day one, we integrate with local legal sources across jurisdictions and are currently available in 12 languages. In just 18 months, we've grown to 70+ employees and 5,000+ users across 20+ countries - with market leadership in Norway and the Netherlands, and active expansion across Europe. We believe technology shouldn't replace legal reasoning, but strengthen it - so the law can work as it's meant to: aligned, accountable, and capable of delivering justice for everyone.

Your role as Senior Full-Stack Engineer & Lead
As Senior Full-Stack Engineer (Backend-Leaning), you'll act as the technical lead for Amplify's platform, owning the service layer and overall architecture across a small engineering team. You'll design the back-end services that power AI-driven coaching, learning, pricing, and user scoring, while defining the API contracts that connect front-end experiences with data pipelines. Success in this role comes from building a platform that is scalable, secure, observable, and designed with privacy at its core.

What you'll be doing

• Design and own Amplify's back-end service layer, providing overall architectural leadership across the engineering team.

• Build the shared trigger and notification engine, LMS backend, pricing services, and pairing/scoring services that power Amplify's core product experiences.

• Design and maintain secure multi-tenant architecture, ensuring strict tenant isolation and privacy across queries, triggers, notifications, and usage data.

• Define API contracts for front-end applications and data pipelines, while making build-vs-reuse decisions across the existing Saga platform.

• Lead technical planning by decomposing the roadmap, reviewing code across frontend and data engineering, and driving architectural decisions.

• Ensure the platform is production-ready, observable, secure, and scalable as Amplify grows.

What you bring to our team

• 7+ years of backend and full-stack engineering experience with significant production experience in TypeScript/Node.js or comparable technologies.

• Experience building event-driven systems using queues or streams, along with rules engines, trigger engines, or notification infrastructure.

• Strong experience designing multi-tenant SaaS platforms with strict tenant isolation and privacy-by-design principles.

• Experience leading or acting as the technical owner within a small engineering team, including architecture, code reviews, and roadmap planning.

• Experience with usage-based scoring or recommendation logic, LMS or workflow products, and cloud platforms such as Azure is a strong advantage.

• Strong engineering judgement with the ability to balance scalability, security, maintainability, and product delivery.

Our team & culture

Outside of work, many of us are active in sports - running, skiing, hiking - not as a mandate, but because we're drawn to the same mindset sport builds: consistency, resilience, and a long-term view. If you thrive in a flat, high-ownership environment, you'll feel right at home.

Why join Saga

• A salary between €4,000–€6,000 gross per month (all-inclusive, based on a 40-hour week), depending on experience and skill set
