Job description

Design and ship end-to-end features across our web platform and backend services that power the ZOLLARO health ecosystem.

Job Description

As a Full Stack Developer at ZOLLARO, you will build and maintain the web platform and backend services that underpin our health ecosystem — from the consumer-facing Next.js site to the APIs powering our smart scale, mobile app, and data pipelines.

You will work across the entire stack: designing database schemas, building performant server-side APIs, and shipping polished front-end features. You'll collaborate with product, design, and mobile teams to deliver cohesive experiences that meet a high quality bar from both a technical and user perspective.

We operate with a lean, senior-leaning engineering team. You'll have real ownership over the systems you build and direct input into technical decisions — not just ticket execution.

What you’ll bring

• 3–5 years of professional experience working across front-end and back-end systems.
• Strong proficiency in Next.js, React, and TypeScript.
• Solid backend experience with Node.js (Express, Fastify, or similar).
• Good knowledge of relational databases — PostgreSQL preferred — including schema design and query optimisation.
• Comfort working with REST APIs and, ideally, some GraphQL exposure.
• Experience with containerisation (Docker) and cloud deployment (AWS, GCP, or Vercel).
• Familiarity with CI/CD pipelines, automated testing, and code review practices.
• Bonus: experience integrating with IoT devices, BLE, or health data standards.
• Fully remote role with flexible working hours.
• Greenfield ownership — you’ll shape systems, not just maintain them.
• Learning and development budget for certifications, courses, and events.
• Paid annual leave + government holidays.
• Collaborative team culture with engineering-led decision-making.
• Competitive compensation reviewed annually.
