[Hiring] Full Stack Software Engineer @Welyk

Role Description

We are searching for Full Stack Software Engineers for an early-stage startup building clinical AI software for the European healthcare market, focused on women's health. The product has the ambition to grow into a broader women's health journey, and will be certified as a medical device under MDR.

The company is led by a CEO with a medical background, has secured significant seed funding, and already has a small structured team across product, design and engineering. This hire will be among the first engineers on the team, working directly with the founders.

• Design, build and ship features end to end: backend services, APIs and user-facing interfaces
• Integrate AI components (LLMs, agents, pipelines) into a real product, with real constraints on correctness, latency and traceability
• Use agentic coding tools as part of the daily workflow, with the judgment to know when to trust them and when not to
• Contribute directly to architecture and product decisions: in a small team, your voice counts from day one
• Help define the processes and practices the team still needs to build, in a startup at seeding stage

Qualifications

• 5+ years of professional software development experience
• Genuine willingness to work full-stack, with real curiosity to pick up new languages, tools and technologies quickly
• Solid habits around automated testing, code review and CI/CD, treated as a practice rather than a checkbox
• Interest in, or hands-on experience with, the professional use of agentic coding tools
• Autonomy and proactivity: at this early stage not everything is defined yet, and this role plays an active part in shaping the processes and practices the team needs
• Willingness to work in a regulated space: building health software comes with regulatory and compliance requirements, and handling them well is part of the job
• Strong written and spoken communication in English, the team's working language (Italian is a plus, not a requirement)

Requirements

• Knowledge of and experience with Rust (nice to have)
• Hands-on experience integrating and managing LLMs in a product, making their output reliable and measurable (nice to have)
• Experience developing medical device software under MDR certification (nice to have)

Benefits

• One of the first engineers on the team, working directly with the founders
• Small team, fast decisions, impact measurable from month one
• Full remote across the EU (CET±2), with one mandatory in-person day per month in Milan, travel and accommodation covered by the company
• Open to both contractor engagements and permanent contracts via EOR (Deel, Remote)
• Stock options
