Are you an SAP engineer who has built software that shipped to real customers — not just customised a single company's system? At Basis Technologies, we're looking for a Senior SAP UI5 Developer who thinks in products, not projects.

THE OPPORTUNITY

Basis Technologies powers intelligent change management for SAP-run enterprises worldwide. Our flagship product, ActiveControl, is used by Kimberly-Clark, Honda, Booking.com and others to govern how technical change moves through their SAP landscapes.

You wouldn't be customising SAP. You'd be writing software that SAP-run businesses depend on to keep their production systems stable.

This is a builder's role. Clean Core is a first-class principle here — not a constraint we're retrofitting around, but the foundation we build on. UI5 is the primary front-end layer, and OData services and REST APIs are the standard integration pattern. ABAP still matters — this is a deep SAP platform product — but the mindset is product engineering, not enterprise customisation.

If that distinction resonates with you, keep reading.

WHAT YOU'LL OWN

UI5 Development & Clean Core

• Design and deliver UI5 components that serve enterprise customers with complex, varied SAP landscapes

• Own your code end-to-end — from design to ABAP Unit tests to deployment, following Agile principles

• Lead code reviews and be an active voice on how the team raises its Clean Core standards

Technical Collaboration

• Work with abapGit as a genuine source control workflow — not a last-resort backup mechanism

• Collaborate directly with the engineering team on architecture decisions — senior engineers have real influence here

• Partner with Product and QA to ensure features are tested, documented, and production-ready

Platform & Ecosystem Awareness

• Understand the broader SAP platform well enough to anticipate how changes affect customer landscapes

• Stay ahead of SAP's Clean Core and BTP roadmap to inform technical decisions early

WHAT WE'RE LOOKING FOR

Strong foundation in:

• SAP UI5 — controls, data binding, ODataModel and JSONModel, component architecture

• OData services and REST APIs as standard integration patterns

• ABAP — object-oriented, enhancement frameworks, and a solid grasp of the underlying platform

• ABAP Unit testing and a genuine commitment to tested, production-ready code

• abapGit and source control as a standard, disciplined workflow

• Agile delivery in a collaborative, cross-functional team setting

Bonus points for:

• JavaScript or TypeScript development outside of UI5

• SAP BTP — particularly as a deployment or extension target

• Experience advocating for or implementing Clean Core in a real, complex codebase

WHY BASIS TECHNOLOGIES

For over 25 years we've helped global leaders like Kimberly-Clark, 3M, and Vistaprint navigate complex SAP change. We're scaling from 130+ employees with purpose — and we've been named one of the UK's Best Workplaces by Great Place to Work three years running.

The engineering team is small enough that your work is visible, your opinions matter, and there's no bureaucracy between you and the people making product decisions. The culture is one where people stay — several of the engineers you'd work with have been here for years.
