At Haiilo, we’re building the digital home where employees effortlessly receive the information that matters — wherever they are. Our platform is used by thousands of people every day and sits at the center of key communication flows inside global companies.

As part of our Integrations Team, you’ll help make Haiilo the place where data, content, and workflows seamlessly come together. Your work will directly shape how smoothly our platform integrates with the broader ecosystem of tools our customers rely on — from HR systems to productivity apps to communication channels.

You’ll join a stable and growing international SaaS company that invests in engineering excellence, product quality, and your development. We work with a modern stack, a modern product approach, and a culture that values autonomy, clarity, strong technical ownership, and long-term thinking.

• 3+ years full-stack experience with strong backend skills (Java + Spring Boot) and solid frontend experience (TypeScript, ideally Angular)
• Very good English proficiency for effective collaboration in an international environment
• Experience with Docker and cloud-based architectures
• Knowledge of SQL and/or MongoDB
• Confidence in making architectural decisions, evaluating trade-offs, and solving problems proactively
• Hands‑on experience with CI/CD workflows, testing practices, and building maintainable, high‑quality systems

We encourage you to apply even if your profile does not yet meet all the requirements for the position. At Haiilo we support your personal development as well as your individuality, no matter what background you have.

• Develop and evolve integrations that connect Haiilo with HR systems, communication channels, identity providers, and productivity tools
• Implement features across the stack, using Java + Spring Boot on the backend and Angular + TypeScript on the frontend
• Contribute to and influence our microservice and micro‑frontend architecture
• Build systems that are reliable, maintainable, observable, and scalable in cloud environments
• Ensure performance, accessibility, and design consistency by using and contributing to our internal design system
• Collaborate closely with designers and product managers to define, scope, and ship impactful features with clear value

Our leadership is dedicated to helping you improve every day, through individual and group workshop sessions, financial support for training, conferences, books, etc. and external learning resources (e.g. access to Blinkist)

🌴Time off:Depending on your location, we offer up to 30 vacation days to take some well‑deserved time off. Our employees in all locations get 2 annual company‑wide self‑care days on top of the normal vacation days (because we love what we do, but we also love a healthy work‑life balance!)

🌟Health & wellbeing:To promote physical and mental wellbeing, we not only offer health insurance for all locations and a discount for sports memberships but also access to Nilo.health. ’Cause healthy employees = happy employer!
