Contract Jobs

Senior AI Engineer, SAP BTP and Public Cloud The Opportunity Most AI engineering roles right now are either pure research or pure integration work - wiring up an API and calling it done.

You'd be joining an agile engineering team working on a cloud-native architecture across SAP BTP and Node.js - owning AI implementation end to end, from RAG-based solutions and LLM integration through to cost optimisation and technical coaching of the wider team.

The team works in an agile setup on a modern, cloud-native stack. English is the primary working language.

DevOps Engineer, IAM and Kubernetes The Opportunity IAM work can get narrow fast. You configure Keycloak, you manage AD, you handle OAuth flows - and then you're stuck doing the same things on repeat in an environment that never really changes. This contract is different.

Windows Systems Engineer (DevOps Focus) The Opportunity You're solid on Windows Server. You know your way around PowerShell. And you've been wanting to move further into DevOps for a while - but your current role keeps pulling you back into the same operational work. This contract gives you a structured way to make that shift. You'll be embedded in a long-running project in a security-sensitive enterprise environment, operating and developing Windows Server 2025 infrastructure while progressively taking on DevOps-adjacent tasks as you grow in the role.

Deep ABAP Skills? Here's a Role Built Around Them. The Opportunity Most SAP development roles ask for a bit of everything and deliver a lot of nothing in particular. This one is different. Our client, a Hamburg-based SAP software company, is looking for a Senior Full Stack Developer whose centre of gravity is exactly where it should be: deep ABAP expertise, modern clean-core principles, and enterprise-grade S/4HANA Private Cloud development. If you're the kind of developer who cares about building things that are robust, scalable and upgrade-stable, you'll find the right environment here. The Role You'll be hands-on in ABAP, RAP, CDS and OData V4 — that's the core of the role, not a footnote. Alongside that, you'll be building SAP Fiori and UI5 frontend components with a real focus on usability and performance, applying API-first design principles, and contributing to CI/CD pipelines. You'll work closely with a Technical Architect and a Senior AI Engineer, which means your work sits at the centre of how this product evolves. Clean-core isn't a buzzword here. It's how the team builds. The Company A Hamburg-based software company operating at the intersection of SAP Private Cloud and cloud-native architecture. The team is technically serious, the product portfolio is mature, and the work is the kind that holds up over time. What You'll Need Several years of SAP full stack development experience Deep S/4HANA Private Cloud or on-prem development background Strong ABAP, RAP, CDS, OData V4 and ABAP OO skills Solid SAPUI5 and Fiori Elements experience How to Apply Your CV doesn't need to be up to date. Send what you have, or just give us a call.

Ready to Architect at the Product Level, Not the Project Level? The Opportunity Most SAP architects spend their careers implementing someone else's blueprint. This role is different. Our client, an established Hamburg-based SAP software house, is looking for a Technical Architect to own solution design end-to-end across their S/4HANA Private Cloud product suite. You won't be handed a design and asked to execute it. You'll be the person making the calls. The Role You'll be responsible for translating complex SCM business processes into scalable, clean-core architecture. In practice, that means: End-to-end solution architecture across SAP Private Cloud environments Owning HLD, SDD and TDD documentation Designing integrations using APIs and event-driven patterns Setting and enforcing clean-core governance and development standards across Engineering An active seat on the Architecture Board, with real input on quality, performance and governance decisions This is a product environment, not a consulting model. The work you do here has a longer shelf life. The Company A mature, Hamburg-based SAP software house with a well-established product portfolio built entirely on S/4HANA Private Cloud. The focus is on supply chain, and the engineering culture is serious about clean-core principles and sustainable architecture. What You'll Need Several years as a Senior or Lead SAP Architect Deep S/4HANA Private Cloud expertise, including ABAP, RAP and SAP BTP Proven knowledge of SCM processes, specifically SD, MM and EWM The ability to work across both business and technical architecture, and translate between the two How to Apply If this looks like the right move, get in touch.
