Senior Full Stack Developer (3 Years)

About us

We are Paxly, a B2B SaaS startup based in Leipzig. 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.

Tasks

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.

Requirements

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

Benefits

What we offer

Hybrid Work

Leipzig 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.
