Senior Software Engineer – Developer Experience / Tooling (PHP) (m / f / d)

Shopware is an international, leading open commerce platform for ambitious companies in digital commerce. With an API-first approach, maximum flexibility, and a strong community, we create future-oriented e-commerce solutions. Our 450 employees across Europe share a passion for innovation, openness, and team spirit.

If you enjoy building tools that make other developers more productive, and you care deeply about APIs, CLIs, frameworks, and workflows that just feel right, this role is for you. As a Senior Software Engineer in the Developer Experience (DX) Tooling team, you will work on the tooling and foundations developers use to build, extend, test, and operate Shopware . Your contributions will directly influence how enjoyable, efficient, and reliable it is to develop on top of our open‑source platform.

This position can be filled on‑site, hybrid, or full‑remote within Germany or specific European countries where we are registered. Your work location will be agreed in advance and forms the basis of your employment contract .

Empower developers :   You design and build developer-facing tools that improve how developers work with Shopware, from local development to CI and production.

Shape DX foundations :   You work on CLI tools, SDKs, scaffolding, APIs, and internal frameworks that power Shopware’s open-source ecosystem.

Open source by heart :   You collaborate with and support a global developer community by maintaining open-source tooling, reviewing contributions, and improving documentation.

Quality & usability first :   You ensure tooling is robust, well-tested, and intuitive, reducing friction and cognitive load for developers.

Bridge teams :   You work closely with core, SaaS, documentation, and community teams to align tooling with real developer needs.

Evolve workflows :   You improve build, test, release, and extension workflows to enable faster and safer development.

This is what you’ll bring to the table :

You have strong professional experience with PHP , ideally in a Symfony‑based ecosystem , and you enjoy building developer tooling such as CLIs, SDKs, or APIs. Having built CLI tools or frameworks before is a plus.

You design clean, stable public APIs and care about long‑term compatibility . Plugin / app architectures, Shopware knowledge or Symfony internals are welcome but not required.

You are familiar with Composer , dependency management , and PHP packaging to build developer tooling and libraries that integrate seamlessly into existing workflows.

A focus on DX , usability , and maintainability guides your decisions, and you improve docs, examples, or onboarding when it removes friction for developers .

You write automated tests and keep quality high through CI feedback loops. Comfort with JavaScript tooling (Node.js / Vue.js) is helpful when collaborating across the stack.

You bring an open‑source mindset and enjoy collaborating in public repositories. An interest in developer advocacy or community support is appreciated.

You work smoothly in agile, cross‑functional teams , communicate clearly with external developers and internal stakeholders, and take ownership to deliver with minimal supervision.

Excellent English communication , written and spoken, enables you to work effectively across teams and time zones. German is a plus, not a requirement.

Good time management and the ability to see problems from an external developer’s perspective round out your profile

This is what we offer you :

Company Culture : Open culture with flat hierarchies, where individual initiative is encouraged.

Employment Contracts : Permanent positions that offer long-term security.

Flexibility : Flexible working hours and options for mobile work and full-remote contracts.

Equipment : Freedom to choose your preferred work hardware.

Onboarding : Well-structured onboarding with support from a personal "buddy."
