COMPANY OVERVIEW Mindpeak is a Hamburg-based AI company dedicated to democratizing cancer diagnostics. Our software supports pathologists in detecting cancer faster and more accurately by applying state-of-the-art deep learning to medical images. Our AI solution is the first to be implemented in clinical histopathology for primary diagnostics in the USA and is used in routine workflows around the world. We tackle a central challenge in modern healthcare: a growing demand for medical image analysis with a static number of cancer experts. By providing powerful, robust tools for visual diagnosis, we help pathologists focus on what only humans can do best—while our technology takes care of the rest. POSITION SUMMARY Role: AI driven (Senior) Backend Developer Python Focus: Building and scaling high-quality backend services that power AI models and digital pathology tools. Establishing AI-agentic development workflows. Team: You’ll be part of the development team, working closely with machine learning, product, and front-end colleagues. You will report directly to our VP Engineering. Digital pathology comes with unique technical challenges: whole-slide images with file sizes of several gigabytes and resolutions up to 100,000 x 100,000 pixels. You’ll help design and implement solutions such as efficient image streaming via an advanced image server, ensuring that our AI models can be served reliably to pathologists, labs, and partners worldwide. In this role, you will play a key part in building up Mindpeak’s AI agentic development knowledge, tooling, and workflows. You’ll work on: * Building a new platform for digital pathology using a modern, multi-agent AI coding workflow. * Turning cutting-edge AI models into robust, scalable APIs for real-world clinical use * Building tools and services to automate our data annotation and image processing pipelines * Integrating scanners, image viewers, and lab information systems into seamless, automated workflows * Shaping and scaling AI-supported development workflows across teams * Shaping technical decisions from the ground up in a fast-moving, high-impact environment Your Responsibilities * Design, develop, test, deploy, maintain, and improve backend services that serve machine learning models in production. * Write clean, maintainable, and well-tested code with a strong focus on reliability and performance. * Build automation tools to streamline and optimize our data annotation pipeline. * Work with technologies such as Docker, AWS, Python, and (partially) React to develop best-in-class digital pathology tools. * Integrate existing pathology hardware and software (e.g. scanners, image viewers, LIS) into automated workflows. * Manage your own project priorities, deadlines, and deliverables with a high degree of ownership. * Collaborate closely with product, design, front-end, deep learning, and infrastructure colleagues to keep everything running smoothly. * Select and implement the most effective technical approach for each task. * Build up AI agentic development workflows, including the evaluation and adoption of AI coding agents to improve developer productivity and software quality. * Define best practices for AI-assisted software development and share this knowledge across the organization.
