• Contribute to Greencube's architecture, technical standards, and engineering culture.
• Write clean, well‑tested, maintainable code.

• 5+ years of full‑stack engineering experience in a production SaaS environment.
• Strong proficiency in a modern backend language (e.g. C#/.NET, Node.js, Python, Go, or Java).
• Strong frontend skills with a modern framework (React, Vue, Angular, or similar).
• Solid experience with relational databases (PostgreSQL, SQL Server, or MySQL) and API design.
• Software engineering craft: testing, CI/CD, code review, pragmatic architecture.
• Care for user experience and attention to detail.
• Experience with healthcare standards (HL7, FHIR, SNOMED, DICOM).
• Experience with regulated software development (ISO 13485, IEC 62304).
• Experience with multi‑tenant SaaS, event‑driven systems, or offline‑first apps.
• Exposure to ML‑powered product features.

• Mission‑driven work with real clinical impact.
• Competitive salary, bonus, and equity.
• New York office at 30 Broad Street, Financial District, with hybrid working.
