We connect packaging buyers with suppliers through our smart procurement platform – think of it as the missing link between “I need 1,000,000 cardboard boxes” and “here’s the best supplier for your specs.” We have hit product-market fit, have paying customers, and now we our looking to scale. Not just the product, also the engineering team. **Who is behind this** Three founders. Torsten is our packaging industry expert – he knows the domain inside out. Klaus and Hendrik are seasoned entrepreneurs with a track record of building and scaling companies. We have done this before. This time, we are doing it in packaging. **The honest situation** Right now, our tech team is tiny: one senior developer and our CTO. We are not a 50-person engineering org with layers of process. We are two people who ship things. That is where you come in. **What you will do** You will be the third engineer – but really, the first hire that shapes how we grow. You will work across our main platform (Java/Angular) and touch our AI-powered document processing system (Python). You will help us build CI/CD pipelines, improve test coverage, and strengthen our engineering foundations. This is not a “implement tickets from Jira” role. You ‘ll have opinions. You’ll push back. You’ll help us decide *what* to build, not just *how*. **The tech** Back-end: Java 17, Dropwizard, PostgreSQL Front-end: Angular 16+ Infrastructure: AWS (EC2, ECS, RDS, S3), Docker, Redis Side quest: Python/FastAPI You don’t need all of it. Java + Angular is the core. The rest you can learn. **What we are looking for** 3+ years of professional development experience Strong in Java or a similar back-end language Comfortable with Angular (or willing to get comfortable fast) You’ve worked with relational databases (PostgreSQL, MySQL) You’ve touched CI/CD, Docker, or cloud infrastructure You take ownership – “not my code” isn’t in your vocabulary Bilingual: English (professional), German (B2+) **Strong plus** You know when to use AI coding tools – and when to write it yourself Experience with modern AI approaches (LLMs, prompt engineering, AI-assisted workflows) Python experience AWS knowledge You’ve worked in a small team or startup before **What we offer** **Hybrid Work** preferred, remote acceptable. Workation in EU possible. **Flexible Working Hours** Ownership, not time clocks. You organize yourself. **Real Impact** Your code runs in production, you decision matters. **Salary** 55.000 - 75.000€ depending on your experience. **Team-Events** We meet 3-4 times a year for team events, because even the best remote culture can't replace a good beer. **Startup with Substance** Solid product, paying customers, zero bullshit. **Our culture** We win and lose as a team. (But mostly we win ;-)) No bullshit. No politics. No endless meetings about meetings. We say what we think, we fix what’s broken, we ship what matters. We believe in a realistic workweek and work-life balance. We’re not impressed by rockstar culture or overtime heroes. But when the roof is on fire, we expect everyone to grab a bucket. That’s the deal. If you’re looking for a place to grow inside a startup – to learn fast, take on responsibility early, and build something real – this is it. **Not for you if** You need detailed specs before writing a line of code You prefer large teams with clear role boundaries You want a 9-to-5 with zero exceptions, ever **Our Proccess** **Speed Dating (15 min)** – Quick mutual vibe check. **In-Depth Interview** – With HR and your future manager. **Meet the Team (optional)** – Because chemistry matters. **Decision & Start** – Good fit? Let's go. **Sounds interesting?** Send us your CV and a few sentences about why Paxly caught your attention. No formal cover letter needed.
