About Applivery

Applivery is the next-generation, AI-driven Unified Endpoint Management (UEM) and app distribution platform. We empower IT and security teams worldwide to secure, automate, and scale their digital workplaces across Apple, Android, and Windows. Recognized in the Gartner® Magic Quadrant alongside giants like Microsoft, our software is trusted globally by market leaders including Mercedes-Benz, Starbucks, Snapchat, Supercell, and BNP Paribas.

We are a high-velocity, product-first scale-up. We don’t do bloated hierarchies or corporate bureaucracy; we thrive on extreme autonomy, speed, and pride in execution. Here, you won’t be a cog in a machine—every person has a direct, visible impact on our product, our culture, and our trajectory.

As we enter our next phase of hyper-growth, we are looking for builders who want to leverage AI, take extreme ownership, and help us scale a product that shapes how the world works. This is the perfect time to hop on board.

About the Role

We are in a growth phase and are looking for a Backend Developer with a product mindset to help us evolve our architecture and build the future of device management.

If you are a problem-solver with the ability to take initiative, are passionate about independent learning and keeping up with technological trends, and enjoy working in international environments, this is the place for you.

What You Will Do

As a backend developer, you won't just write code; you'll be a key player in designing high-availability systems. Your work will directly impact how thousands of companies interact with their Android, iOS, macOS, and Windows devices, ensuring that our APIs are robust, scalable, and secure.

  • Design and Implementation: Collaborate closely with the Product team to define and build new features that solve real problems for our customers.

  • Architecture and Performance: Identify bottlenecks and propose architectural improvements to ensure the scalability and speed of our platform.

  • Code Quality: Maintain high quality standards through code reviews, clear documentation, and the implementation of tests (unit and functional).

  • Continuous Innovation: Research and propose the adoption of new technologies and best practices that optimize our development flows.

  • Maintenance: Resolve incidents and debug existing APIs, ensuring a frictionless experience.

What You Will Need

  • Core: Solid experience developing backend applications with Node.js and TypeScript.

  • Ecosystem: Proficiency in libraries and frameworks such as Express, Zod, and Mongoose.

  • Databases: Experience working with relational and non-relational databases (MongoDB, PostgreSQL).

  • Cloud: Knowledge of cloud infrastructure services (AWS, GCP, and/or Cloudflare).

  • Messaging: Experience with event queueing systems or asynchronous messaging (RabbitMQ, PubSub, etc.).

  • Quality: Familiarity with automated testing and version control tools (Git).

  • Language: We work in quite an international environment so you will need to be fluent in English.

Nice to Have

  • Experience with payment gateways (Stripe), real-time communication (Socket.io), and security (OWASP).

  • Knowledge of Docker, Kubernetes, and CI/CD pipelines.

  • Familiarity with the mobile and desktop operating system ecosystem (Android, iOS, macOS, Windows).

  • Experience working under Agile methodologies.

Benefits

As a certified Great Place to Work®, we believe that driving high performance goes hand-in-hand with cultivating total trust. We are scaling fast, which means our goals are ambitious and the environment is dynamic, but we back that challenge up with the autonomy, flexibility, and top-tier benefits you need to thrive.

  • Trust & Flexibility: We operate on an objective-driven, results-oriented culture. We trust you to manage your time and balance your life effectively, without strict clock-in rules or micromanagement.

  • The Friday Finish: Kickstart your weekend early with short Fridays, wrapping up at 3:00 PM all year round.

  • Generous Time Off: Enjoy 23 days of vacation + December 24th and 31st off. Plus, your birthday is a holiday (and if it falls on a weekend, you can take the closest working day off!).

  • Flexible Remuneration (via Alan): Optimize your net salary with tax advantages for meals, transport, childcare, and training.

  • Health & Wellness: Access discounted health insurance (100% covered by Applivery after your first year) plus a monthly Wellness Stipend to spend on your choice of sport, gym, or well-being activities.
