📄Stellenbeschreibung

Python, FastAPI and PostgreSQL in a system we built entirely ourselves. Full stack welcome.

Berlin or nearby, hybrid. Full-time, permanent. Start: as soon as possible

What this is about

Careship helps families find reliable support in everyday life: all across Germany, through self-employed caregivers and our own employed caregivers.

Behind both stands a platform we built entirely ourselves, live since August 2026: a Python backend, an internal staff portal, an app for customers and an app for caregivers.

The system covers everything from the first inquiry to payroll: matching, scheduling, care budgets, billing with care insurance funds, payment processing and digital contracts, plus email, chat, WhatsApp and phone calls in one inbox.

It is live, it runs the operations of two companies, and it grows every week.

This is why we are looking for the second person in our permanent engineering duo.

Your role

You work as one of two engineers on our system, with a focus on the Python backend: data model, business logic, APIs and the integrations our operations run on.

If full stack is your thing, the rest is open to you: the staff portal in Next.js and our two apps in React Native.

You share responsibility and cover for each other, in everyday work and during vacations.

You build features from the data model through the business logic to the finished API endpoint, and all the way to the screen if you want.

You work on core topics like the budget engine, billing, the payroll pipeline and matching. Logic where diligence really counts.

You maintain code in production that real people use every day: our operations team, caregivers, and customers with their families.

You work directly with product and the tech lead, no layers in between. Requirements arrive as fully worked-out specifications from our knowledge base, not as two-line tickets.

You get freedom and real responsibility: the system is brand new, much of it is taking shape right now, and you help decide where it goes. The roadmap includes shift planning, analytics, a marketing module and an ambassador platform.

Our stack

Backend: Python 3.12, FastAPI, SQLAlchemy 2, Alembic, PostgreSQL, on Google Cloud (Cloud Run, Pub/Sub, Cloud Storage)

Portal: Next.js 16, React 19, TypeScript, MUI, TanStack Query, generated OpenAPI client

Apps: React Native with Expo, shipped through the app stores

Integrations: Google Workspace (Gmail, Calendar, Meet), Auth0, Aircall, WhatsApp and DATEV, plus payment and e-signature providers

How we work: AI-assisted. Specifications, code and reviews are created with AI support, as our everyday standard, not as an experiment.

What you bring

At least 3 years of experience in professional product development, more is a plus

Solid Python experience in production, ideally with FastAPI and SQLAlchemy or comparable frameworks

Confidence with relational databases and SQL, PostgreSQL in our case

You already code with AI support as a matter of course, ideally with real enthusiasm. For us this is a requirement, because it is how we work every day.

Diligence where mistakes cost money or trust: billing, payments, personal data

Fluent English. German is a plus.

Appetite for a small team with a lot of responsibility and a direct line to the people who use your software

Nice to have

TypeScript, React, React Native or Next.js, if you also want to work on the frontend

App store releases and Expo EAS

Google Cloud, Google Workspace APIs, or experience with payment and e-signature integrations

Experience in regulated domains such as health, care or fintech

WebSockets and real-time features

German language skills, since our domain and our specifications are in German

What we offer

A brand-new system with real room to shape it: two engineers, clear specifications, no decades-old legacy, and plenty of space to keep building

Freedom and responsibility from day one, flat hierarchies, no meeting marathons

Real social impact: your work helps seniors get support and makes sure caregivers are paid fairly and on time

Home office with regular shared days at our Berlin office

Several weeks per year of fully remote work, from abroad if you like

30 days of paid vacation

A new MacBook with serious power

An annual learning budget plus two extra paid learning days

An Urban Sports membership

Deutschlandticket (Germany-wide public transport pass)

Regular team events

What happens next

Our process is deliberately fast and straightforward, in three steps: a short intro call, a technical interview, and finally a small case study plus meet the team.

No need to send us a novel. Your CV, GitHub or LinkedIn profile and a few sentences on why this is exactly your thing are plenty.

Compensation

The annual salary for this permanent, 40-hour-per-week role is EUR 60,000–70,000 per year.

Join us

If you match most of these requirements and want to apply your engineering skills to meaningful work, we encourage you to send us your application through the platform.

We look forward to reviewing your background and discussing how you can contribute to our team in Berlin.
