Role Description The Atlas API Experience (APIx) teams are part of MongoDB Atlas Data Services, a diverse group of individuals who develop the capabilities to run MongoDB globally. APIx’s mission is to create delightful experiences that bring developers along on the journey from eager beginner to sophisticated MongoDB expert! As part of our team in APIx, you will be responsible for improving & extending our API platform & downstream tooling, such as the Atlas CLI. Our mission is to help Atlas customers automate their workloads easily through APIs & support internal teams contributing to the API. This role can be based in our Dublin office or remotely within Ireland. What will you do? - Propose, design, implement and support product features for the MongoDB Atlas API Platform & MongoDB Atlas DevTools, such as AtlasCLI. - Build tooling that enables MongoDB users and developers to succeed, using programming languages such as Golang, Java, Python & Javascript/Typescript (Experience in at least one of the above is desirable). - Design and develop software integration components utilizing MongoDB’s technology (i.e. database, mobile, search, etc.) in larger contexts and integrate into partner frameworks or solutions. - Incrementally ship elements of sophisticated projects. - Assist with investigating and solving problems experienced by our customers. Our team has a Level 2 support rotation. - Apply our core values to your planning, designing, and coding work. Qualifications - Inspired by building systems that manage infrastructure at scale. - Approachable, curious, and intellectually honest. - Collaborate and communicate effectively across multiple teams, locally & remote across timezones, internally and externally as required, to drive projects to completion. - Enjoys an environment where you can coordinate your own time, prioritizing, and acting on multiple tasks concurrently without manager oversight. - Some experience building Infrastructure as Code (IaC) tooling & integrations. - Familiar with cloud infrastructure platforms, tools and concepts (Amazon AWS, Google Cloud Platform, Microsoft Azure, etc.). Requirements - In three months, you'll have become familiar with our developer tools and the existing features most relevant to integrations. - In six months, you will be building features and leading your projects. You will share knowledge with the team, collaborating where needed to achieve our team goals. - In nine months, you will be fully embedded in the team. As well as leading your projects, you will be contributing ideas to the team roadmap, improving how we work. You will be mentoring other team members, helping them learn from your experience. Benefits - Generous compensation package (top-range salary, equity, comprehensive benefits). - Flexible working options with a focus on results rather than time spent in the office. - A high level of independence in your day-to-day work. Propose innovative solutions to existing problems and own the delivery from start to finish. - Opportunities to learn on the job (time and support to upskill in new technologies and learn new programming languages, as well as an allowance for educational material). - Exposure to a wide variety of market verticals and a broad spectrum of interesting use cases. - You'll be joining a supportive and collaborative team that values its culture and promotes a positive work environment! - Upon joining, you will have the opportunity to learn everything there is to know about MongoDB via specialized training on the MongoDB University platform and highly supportive colleagues.

• Translate business logic into high-quality code, advocating simplicity and sound architectural practices • Actively participate in the architecture, definition, and implementation of new features, as well as bug fixes • Understand complex problems with limited initial definition and design robust technical solutions • Review code delivered by team members, acting as a facilitator and raising the team's technical maturity • Break down large deliverables into small, cohesive increments that provide continuous value • Monitor the stability, performance, and behavior of solutions deployed to production • Actively contribute to improvements, documentation, and new standards in the Engineering knowledge base.

Role Description JTL is one of the leading providers of e-commerce software in the German-speaking region — with around 450 employees across the group and more than 50,000 customers across a wide range of industries. We develop scalable, flexible solutions for the online retail of the future, from ERP systems to shop and marketplace integrations. You'll join the team behind our Fulfillment Network — the backend that keeps orders, stock, and logistics flowing for thousands of merchants. We care about systems that stay up and get better with every release, and we keep ownership close: the people who build a service also run it. You'll fit in here if you like backend problems that carry real operational weight. This is a backend-first role — you think of yourself primarily as a backend developer, and the core of the work lives in the .NET / MongoDB space. You'll develop the REST API behind our Fulfillment Network (FFN) and Trade Network (TDN), products used by thousands of customers every day, and own the integration points where backend services and the JTL-Wawi client need to work together seamlessly. You think in systems and data flows rather than isolated tickets, switch comfortably between technologies, and thrive in a fast-moving, startup-like environment. The principle here is simple: you build it, you run it. You don't own the underlying hardware, but you own your application's operational readiness end to end — when outages happen, you resolve them the same business day. Stability and availability matter to you as much as shipping new features, and you take pride in making the product faster and more reliable with every iteration. Responsibilities - Develop our FFN / TDN REST API further and own backend features end to end, from design to production. - Build the integration with JTL-Wawi, especially where backend services and client-side behavior need to work together seamlessly. - Support complex business and synchronization scenarios, and handle production incidents and customer-reported issues. - Operate and deploy the API through our pipelines — covering performance optimization, observability, and operational reliability. - Own the operational readiness of your application end to end: you build it, you run it, and you resolve outages within the same business day. Qualifications - C#, modern .NET (.NET 8+), and ASP.NET Core are your primary stack — with solid, hands-on experience building and operating backend services in production. - You've built and maintained complex backend systems with a focus on robustness, maintainability, and scalability — using modern .NET patterns (async/await, dependency injection, clean architecture), CQRS, and Domain-Driven Design (DDD). - You know MongoDB well (data modeling, performance optimization, high-volume datasets) and have strong SQL skills, including writing and optimizing complex queries for performance. - You design and consume REST APIs on both sides (Core & Connect), and you can identify and resolve bottlenecks across APIs, database access, and backend workflows. - You have hands-on observability experience with Prometheus and Grafana — metrics, dashboards, alerting, production analysis — and you resolve customer-reported issues pragmatically and reliably. - You've worked with AI-assisted development and agentic, automation-first engineering where it creates real value. - Good German communication skills. Nice to have - ERP or e-commerce background. - Logistics or fulfillment domain knowledge. - PHP — practical production experience, ideally within the Laravel ecosystem. - MariaDB / MySQL — data modeling and query optimization. - Livewire / Tailwind — no deep expertise required, but able to work independently. - WPF — practical experience working on existing desktop UI applications. - DevExpress — experience with component-based desktop UI development. Benefits - Remote-first within Germany, with the option to work remotely from eligible countries for up to 180 days per year. - Meal allowance of up to €115 net per month. - Ergonomic workspace allowance for your home office setup. - Regular team events, company-wide gatherings, and summer and Christmas parties to stay connected as a remote-first company. - EGYM Wellpass and JobRad subsidy. - Financial benefits including capital-forming payments (Vermögenswirksame Leistungen) and a company pension scheme.
