Software Engineer (Data & AI) with Tech Lead potential

This role is roughly half hands-on engineering and half leadership. You will work on ML/AI and the components around it: infrastructure, data pipelines, cloud, and user-facing applications. The work is end-to-end; the model is one part of the system.

What will you do?

• Architect data/AI solutions for healthcare clients, including data platforms, ML/AI systems, and agents
• Lead a team of 2–5 engineers on specific projects while remaining hands-on
• Own technical quality through code reviews, standards, and best practices
• Conduct pre-sales technical work, including client discovery sessions, scoping, and technical proposals
• Mentor junior engineers
• Build internal IP and reusable components for healthcare AI
• Contribute to technical and strategic direction

What is required?

• 5+ years in software and ML/AI engineering, including responsibility for others in a formal or informal role
• Production experience with systems running in client environments
• Problem-solving mindset and willingness to engage deeply with clients' business needs
• Active use of LLMs, agents, and frontier tooling to automate work; ongoing awareness of industry developments
• Genuine interest in healthcare; prior healthcare experience is not required
• Full-stack engineering mindset: Python/AI as the core, with ability to work across infrastructure, data pipelines, cloud, and surrounding systems
• Ability to scope, estimate, and deliver projects end-to-end

Nice to have

• Knowledge of healthcare systems, standards, and formats, such as HL7/FHIR, DICOM, and Nextflow
• Bachelor's, Master's, or PhD in Computer Science, Biomedical Engineering, ECE, or a related field
• Experience building or leading engineering teams in a B2B or consulting environment
• Cloud certifications, such as AWS Solutions Architect
• Experience with classical ML, deep-learning frameworks, and a modern LLM stack
• Public speaking, conference talks, technical writing, or open-source contributions
• Currently based in or willing to relocate to Poznań, Poland

What you get

• Work on production systems used by medical clients, affecting patients, public health, and research
• Early adoption of relevant new models and tools
• End-to-end work across ML, infrastructure, data, client systems, and user-facing applications
• Path to Tech Lead with direct influence on technical direction, hiring decisions, and company strategy
• Fully remote work with flexible hours
• Dedicated training budget
• Regular Tech Fridays for knowledge sharing
