🏢 About the company
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.
Being early-stage, several core technology decisions are still being made together with the team as it grows: some have already been settled, others are actively being shaped, and this hire will have a real say in them.
What you'll do
Design, build and ship features end to end: backend services, APIs and user-facing interfaces
Work across the stack with full availability to contribute to mobile development as the product's mobile technology choices are finalized
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
Technical requirements
5+ years of professional software development experience
Genuine willingness to work full-stack, including mobile development, 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)
Nice to have
Knowledge of and experience with Rust
Experience with AWS
Hands-on experience integrating and managing LLMs in a product, making their output reliable and measurable
Experience developing medical device software under MDR certification
You're a great fit if you want to join as one of the first engineers on a product and see your architectural decisions stay in the codebase for the long run, if you can move without being walked through every step, if you know how to work autonomously while keeping code quality and team collaboration high, and if you care about working on a real problem in a large, underserved, fast-growing market.
What the company offers
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)
