Deine Rolle
Als dritter Engineer bist du "the first hire that shapes how we grow". Du arbeitest über die gesamte Plattform – vom Java/Angular-Backend bis zum AI-Dokumentenprozessing in Python. Du baust CI/CD-Pipelines und stärkst unsere Engineering-Grundlagen.

Diese Rolle bedeutet Ownership und Mitentscheidung – nicht nur Tickets abarbeiten.

Deine Aufgaben
Entwicklung im Java/Angular-Stack (Backend und Frontend)
Python/FastAPI für AI-Dokumentenverarbeitung
CI/CD-Pipelines und Infrastruktur aufbauen und verbessern
Testabdeckung und Engineering-Robustheit erhöhen
Architektur- und Technikentscheidungen mitgestalten

Was du mitbringst

Must-have:

3+ Jahre professionelle Entwicklungserfahrung
Starke Java-Skills (oder vergleichbare Backend-Sprache)
Angular-Erfahrung (oder schnelle Einarbeitung)
Relationale Datenbanken (PostgreSQL/MySQL)
CI/CD, Docker oder Cloud-Infrastruktur
Professionelles Englisch und mindestens B2 Deutsch
Ownership-Mentalität und Selbstständigkeit

Strong Plus:

Erfahrung mit AI-Coding-Tools
Moderne AI/LLM-Erfahrung
Python-Kenntnisse
AWS-Erfahrung
Startup- oder Kleinteam-Hintergrund
Unser Tech-Stack
Backend: Java 17, Dropwizard, PostgreSQL
Frontend: Angular 16+
Infrastruktur: AWS (EC2, ECS, RDS, S3), Docker, Redis
Emerging: Python/FastAPI für AI-Features
Unsere Kultur
"No bullshit. No politics. No endless meetings."

Work-Life-Balance hat Priorität vor Rockstar-Kultur. Aber wenn's brennt, sind alle da.

Was wir bieten

Hybrides Arbeiten – Leipzig bevorzugt, remote möglich
Flexible Arbeitszeiten – Ownership-basiert statt Stechuhr
Echter Impact – Deine Arbeit zählt direkt
Team-Events – 3-4x jährlich
Solides Startup – Bootstrapped, No-Bullshit-Kultur

Klingt interessant?

Schick uns deinen CV und ein paar Sätze zu dir. Kein formelles Anschreiben nötig.

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.

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

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.

Sounds interesting? Send us your CV and a few sentences about why Paxly caught your attention. No formal cover letter needed.
