Senior Full-Stack Engineer - Platform Architecture & Development (Angular / Node.js, Zürich On-Site)

Über den Job

IR Suite AG is building the operating system for modern investor relations. We enable publicly listed companies to identify, acquire, and engage investors at scale through a unified platform that combines data intelligence, communication, and marketing automation.

We are early, fast-moving, and opinionated about building high-quality software. Our ambition is to become the operating system for IR teams globally.

To get there, we are looking for a highly experienced Senior Full-Stack Engineer who has built and scaled real products, not just features, and wants to take ownership of a modern SaaS platform end-to-end.

This is not a maintenance role. You will help define architecture, make critical technical decisions, and build core systems from the ground up.

This is a 100% on-site role in Zürich. We do not offer remote or hybrid setups.

Your responsibilities

• Develop and maintain our web application with Angular and Node.js/NestJS
• Build clean, user-friendly frontend interfaces with a strong UI/UX focus
• Design and optimize APIs, data flows, and components in our Nx monorepo
• Work with PostgreSQL and ensure reliable, performant data access
• Integrate external APIs and services (e.g. ad platforms, financial data providers)
• Implement and connect AI-based features (e.g. assistants, automation, content generation)
• Ensure code quality through testing, reviews, and CI/CD
• Collaborate closely with product, design, and QA

Your profile

• Several years of experience as a full-stack engineer, ideally in a SaaS or startup environment
• Strong skills in Angular (ideally v20 or latest), TypeScript, HTML5, and CSS/SCSS
• Experience with Tailwind CSS is a plus
• Solid backend experience with Node.js, NestJS, and Express
• Model and optimize data structures and queries in PostgreSQL and other databases
• Familiarity with REST APIs and authentication
• Experience with Git, CI/CD, and Docker
• Experience with Nx monorepo, AWS, and AI services (e.g. OpenAI API) is a plus
• Ensure high engineering standards: testing, code reviews, CI/CD
• Independent, structured, hands-on working style with a startup mindset
• Team-oriented, proactive, and solution-focused
• Fluent English, spoken and written; German is a plus

Our tech stack

• Frontend: Angular (v20, latest), TypeScript, Tailwind CSS
• Backend: NestJS (Node.js), Express
• Database: PostgreSQL
• Architecture & Tooling: Nx Monorepo, REST APIs
• Infrastructure: Docker, AWS
• AI & Integrations: OpenAI API and other AI/third-party services

What we offer

• The chance to build a core product in an early-stage startup
• High level of ownership and direct impact on the product and architecture
• Close collaboration with the founders and a small, focused team
• Modern on-site workplace in Zürich
• Competitive compensation
