Senior Backend Engineer (Python) - Remote

Breathment; Deutschland; Remote; EUR 90,000 - 130,000; Full time

Job summary

Breathment, a Munich-based digital health startup, is seeking a senior engineer with expertise in computer vision and production Python backend development. You will own the path from neural-network output to patient-facing visuals and clinician reports, shipping robust features to production with Kubernetes and GPU inference.

Responsibilities include building the CV pipeline, reporting layers, and a scalable FastAPI backend (MongoDB, Redis).

Qualifications

• 5+ years of professional software development in Python.
• Experience building production REST APIs with FastAPI or equivalent.
• Hands-on experience with deep learning frameworks (PyTorch or TensorFlow).
• Strong experience with NoSQL databases (MongoDB) and scalable data models.
• Proficient Git/GitHub workflow with CI and reviews.
• Fluent English; German is a plus.

Responsibilities

• Own the computer-vision pipeline turning pose-estimation output into repetition counts, posture feedback and set-by-set exercise analysis.
• Design the reporting layer that converts raw movement data into clinical reports read by physiotherapists.
• Build and extend our Python backend (FastAPI, MongoDB, Redis) behind the patient app and clinician platform.
• Ship to production on Kubernetes with GPU inference services and ensure tests, monitoring and clean handovers.
• Collaborate with product, physiotherapists and mobile team to propose solutions rather than waiting for tickets.

Job description

Breathment is a Munich-based digital health startup. We digitize pulmonary rehabilitation for people living with chronic respiratory diseases such as COPD: our app guides patients through therapy exercises at home, watches their movement through the phone camera and gives feedback in real time, while physiotherapists and physicians follow their progress remotely through our telemonitoring platform. We work with German clinics, physiotherapists and health insurers, and every release reaches real patients. We are looking for a senior engineer who is at home in both worlds: computer vision and production backend. You will own the path from neural-network output to what the patient sees on screen and what the therapist reads in the report.

Tasks

• Own the computer-vision pipeline that turns pose-estimation output from our neural networks into repetition counts, posture feedback and set-by-set exercise analysis.
• Design the reporting layer that converts raw movement data into clinical reports physiotherapists act on.
• Build and extend our Python backend (FastAPI, MongoDB, Redis): the API behind the patient app and the clinician platform.
• Ship to production on Kubernetes with GPU inference services, and stand behind what you ship: tests, monitoring and clean handovers.
• Analyse requirements together with product, physiotherapists and the mobile team, and propose solutions instead of waiting for tickets.

Requirements

• 5+ years of professional software development in Python, including production REST APIs (FastAPI or comparable).
• Hands‑on experience with deep learning frameworks (PyTorch or TensorFlow). You have built real product features on top of model output, not only trained models in notebooks.
• Solid experience with NoSQL databases, ideally MongoDB, and with data models that survive growth.
• A fluent Git and GitHub workflow: branches, reviews, CI.
• Strong analytical thinking and an independent, structured way of working. You can take an ambiguous problem and drive it to a shipped result in a remote team.
• Professional working proficiency in English. German is a plus, not a requirement.
• Genuine interest in startups: you want responsibility, and you want to see the effect of your work on patients.

Nice to have

• Pose estimation, human motion analysis or video processing (OpenCV, MediaPipe or similar).
• Docker, Kubernetes and cloud deployments; workflow engines such as Temporal.
• Software in a regulated environment: medical devices, health data, GDPR.

Benefits

• Impact you can see: your code helps patients rehabilitate at home instead of waiting months for a clinic place.
• Remote‑first: work from anywhere.
• A small senior team with short decision paths and direct access to founders, physiotherapists and users.
• A modern stack: Python 3, FastAPI, MongoDB, Redis, PyTorch, Kubernetes, GPU inference.
