[Hiring] Senior Backend Engineer @Breathment

Role Description

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.

• 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.

Qualifications

• 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.

Requirements

• 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.
