Job description

Do you want to make a global impact with your development skills? And do you want to actively contribute to the further development of our platform and services, creating opportunities for both the organization and yourself? Then this might be the job for you!

About Shypple

Shypple makes shipping simple.
With our easy-to-use platform and expert services, we are simplifying the complex world of logistics and providing our customers with a seamless shipping experience.
Our platform acts as a centralized dashboard, offering real-time visibility on every aspect of the supply chain and includes a wide range of features such as booking, planning, delivery, and communication possibilities.
As a digital service provider, we are revolutionizing the logistics industry by bringing ease, accountability, and efficiency to the supply chain while lowering hassle, communication, and costs. We believe that the perfect solution to disrupting a traditional industry is a smartly developed system combined with a high-quality customer experience.
Your role as Back-end developer

You will be working on simplifying a traditionally complex business, turning it into an intuitive and worldwide scalable product that enables companies to manage logistics in a more time and cost-efficient way. You’ll join a dedicated squad of 4-5 engineers working on a shipping platform that is growing fast and to which many new features are constantly being added.
Together with the team, you (pro) actively contribute to developing new features and are responsible for the technical future of the platform. Your opinion and ideas really matter at Shypple. You are a senior voice that's genuinely listened to, not a ticket factory.
The focus of this position is on the back-end development of logic on the server-side, the definition and maintenance of our services, and ensuring high performance and responsiveness of the application, and driving the technical evolution of your domains. You will work closely with product owners, analysts, a site reliability engineer, and, of course, your colleague developers.

Regular activities

• Develop and maintain clean, efficient, and scalable Ruby code:

• Own backend features end-to-end in our Ruby on Rails API - from domain modelling and database design through endpoints, service objects, tests, and production rollout;

• Take ownership of a core domain (e.g. financing, performance) and drive its technical evolution;

• Collaborate with cross-functional teams to design, implement, and deploy a high-performance application;

• Contribute to platform and architecture decisions: scalability, performance (query/N+1 optimisation), and reducing tech debt across the codebase;

• Analyzing problems, spotting edge cases, and designing high-quality solutions for them;

• Raise the engineering bar through thorough code review, strong testing discipline, and pragmatic technical guidance to the rest of the squad.

• What Makes Shypple unique? At Shypple, you’ll join a multicultural, collaborative team with a flat hierarchy where teamwork is key. We thrive on innovation, constantly reimagining logistics with AI and digital solutions. Your work will have a global impact, directly shaping how businesses manage their supply chains. We offer autonomy and ownership, giving you the freedom to define technical goals and drive projects forward.
  Enjoy a healthy work-life balance with hybrid work options, team activities, and a supportive culture. Technically, you’ll tackle scalability and performance challenges, work with cutting-edge technologies, and have dedicated time for technical debt management, ensuring a future-proof platform.

Job requirements

We ask

We're looking for someone with 6+ years of experience, ideally with Ruby on Rails. We're completely open to similar backend languages—like Python—as long as they are comfortable knowing that our core stack is Ruby, and that's what they’ll be working on day-to-day. We care more about strong engineering fundamentals than exact language matches, but Ruby will be their main tool here.

• Solid PostgreSQL/SQL depth: complex queries, indexing, query performance, and N+1 awareness;

• Real testing discipline;

• A strong end-to-end sense of ownership, attention to detail, and a production-ownership mindset;

• You have a problem-solving mindset and you are a collaborative team player;

• Good verbal and written communication skills in English (fluent);

• The ability to learn new things quickly and understand a business and its product requirements;

• Bonus (not mandatory): Kubernetes knowledge or interest in pipelines, CI/CD.

• 
  Living abroad?
  This position requires relocation to the Netherlands. We will provide a relocation package.

You get

• A great working environment with a team of talented developers who work together for extraordinary success;

• A salary between EUR gross 70.000-95.000 a year (depending on your experience);

• A clear path toward technical leadership or deep domain specialisation;

• Good secondary benefits (e.g. 25 vacation days, pension contribution, in-office breakfast, employee stock option plan);

• The opportunity to be a part of a great adventure where you can grow, develop, and get the best out of yourself, including a yearly budget for personal development;

• An office in the heart of Rotterdam.
