About the role

We are Team Purchase Experience and we are part of the Tech & Data team at Thomann.io. We take ownership for a Checkout that makes sealing the deal a joy for our customers and a seamless process for our internal departments - even long after the equipment has been delivered.
We refine the Thomann Checkout Funnel, integrate Payment Solutions, enable complex Shipping Scenarios and increase Self-Service capabilities for musicians worldwide. Regular collaboration with other Teams & Departments outside of Thomann.io makes that possible.

Currently, we are 8 people working together as a cross-functional team on a daily basis:
Aryo, Andrew & Fabian are our Software Engineers collaborating on new features and technical concepts, fixing bugs, writing tests and sharing memes.

Soli ensures we can release new features with confidence as our Quality Engineer.

Josephine strategizes on how to improve customer satisfaction as our Product Owner while taming our Jira Backlog & Stakeholders.

Sven supports on a technical & personal level to remove blockers for our mission as our Engineering Manager.

Shirin advocates for our customers while turning complex flows into great experiences as our Product Designer.

Eitay uncovers the stories behind our numbers to back up our decisions as our Product Analyst.

We innovate, evolve, collaborate: To support us, we are looking for another Senior Software Engineer (f/x/m) proficient in PHP and related Backend Technologies.
We work remote, distributed, together: Whether fully remote within Germany or on-site in our offices in Berlin & Erlangen - always as a team, always customer-oriented and data-driven.

Here’s what you’ll be doing
Work cross-functionally to refine the customer journey across the order lifecycle.

Integrate and optimize local payment methods catering to international markets.

Solve Logistics puzzles by tackling complex shipping logic.

Increase the observability of our mission-critical applications to spot (and fix) issues before our customers do.

Show your API Craftsmanship by building and maintaining internal APIs, while integrating external APIs to connect us to the wider Thomann ecosystem and beyond.

Take ownership of features that directly move the needle for the business while tackling technical debt that sharpens your architectural skills.

What you should bring to the table
At least 4 years of current work experience as a Software Engineer, with a deep understanding of PHP and common frameworks (e.g. Symfony).

You are familiar with OOP concepts, common design patterns and complex database structures.

You are experienced in first navigating, then improving complex legacy code bases with business requirements & restrictions in mind.

You manage code & dependencies with Git & composer. Code quality is important to you, secured by automated tests.

Code reviews are not a nuisance to you, but serve as a basis for improving & sharing your knowledge.

Daily work happens in English. Since we coordinate closely with our German headquarters, German is a big plus - but if you’re an English speaker willing to learn, we’ll support you.

Our tech stack
Shop-Backend: We are on PHP 8.4. We take full responsibility for our framework and adhere to established standards (e.g. PSR) during development.

Shop-Frontend: We use React & Typescript on the client side while leveraging Tailwind for styling and design.

MySQL & Memcached provide our customers with reliable and fast data.

What we have to offer
Flexible working hours and location, with the option to go into the office (fully-remote possible)
