Looking to work on something that actually makes work better for real people? Our Employee Experience Team is on a mission to help employees feel connected — to their company, their colleagues, and what’s happening around them. We build features that inform, engage, and bring people together within the product — because the feeling of belonging isn’t just a nice-to-have, it’s critical.

We\’re now looking for a Backend Engineer (intermediate level) to join us — someone with solid experience building backend services in Java, who wants to contribute to a meaningful, people-focused product. You’ll work closely with product and design, help shape technical decisions, and bring features to life that have a real impact on the employee experience across companies.
It is your chance to enter an already grown and successful company while being able to still leave your visible footprint.

What we’re looking for:

• Your background: At least 3 years of hands-on backend development experience, ideally in fast-paced product teams
• Tech skills: Strong skills in Java and Spring Boot — you’re confident building and maintaining backend services. Experience with SQL databases (ideally PostgreSQL), comfortable working with Docker, Kubernetes and cloud environments

• Your approach: You care about writing clean, maintainable code — following best practices like testing, static code analysis, monitoring, and more

• Teamwork: A team player, who takes responsibility for what they do and who is able to collaborate and share knowledge with excellent communication skills in English
• Curiosity: We welcome your ideas to enhance our products. You should be eager to learn about new technologies, especially the use of AI and how we

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.

What you’ll do:

• Build and maintain backend services in Java + Spring Boot, with a strong focus on performance and reliability

• Help shape and evolve our microservice architecture, contributing to backend decisions in a growing team
• Using the shape up method and agile principles to develop the best possible software, while engaging in technical discussions and product decisions
• Helping define, test, monitor, and operate the product end-to-end — from the first idea to running it in production

What we offer:

Remote/hybrid role: We value flexibility and teamwork. If you live within a commutable distance from one of our office locations, we require you to work on-site at least one day per week, with Wednesdays as the designated in-office day. While Wednesday is the minimum, we recommend spending 2 (or more) days in the office each week. For those further away, we look forward to seeing you two days per month during our team events to foster collaboration and team spirit

Company Vibe: We value spending time together, so you’ll get to join regular team socials, themed afterworks (e.g. Pride Month, Cultural Awareness Month, etc.), in-person workshops, and our annual company week in Hamburg

Growth: At Haiilo, we are passionate about personal and professional growth. 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!

Sustainability: We only have one planet: We understand the importance of sustainability. We are a carbon-neutral company, our merch is sustainable and we offer exclusive discounts for sustainable brands through FutureBens

????Diversity & Inclusion: We are committed to a diverse and inclusive environment. As an international and multicultural team with different skills, ideas and experiences, we actively work to represent and promote diversity in the company
