Senior Full Stack Engineer to Health Tech Startup

About The Opportunity

Every day, 15% of healthcare appointments are lost to last-minute cancellations, while patients wait weeks or months for care. At Zymego, we are changing that. Our intelligent scheduling platform connects patients to real-time openings, reducing delays, easing staff workloads, and making healthcare more human.

To date, we have saved clinics thousands of hours and shortened patient waiting times by over 1,700 years – and we’re just getting started.

Zymego is a fast-growing startup backed by the Nordic venture capital firms Industrifonden, Spintop, and Icebreaker VC. We are currently expanding in Sweden and the UK and are now looking for a Senior Full-Stack Engineer who wants to help shape the future of digital healthcare.

You will be joining a close-knit, diverse team with a mix of professional and cultural backgrounds, where we learn from each other every day.

Why This Role Stands Out

Collaborative Technical Ownership

• Design and optimise core systems: PostgreSQL schemas, GraphQL APIs (Postgraphile/TypeScript), and clinician workflows (React/MUI)
• Solve mission-critical challenges: Enhance scheduling algorithms, streamline clinic operations, and ensure compliance with healthcare regulations
• Own end-to-end feature development: From PostgreSQL schema design to React-based UI implementation
• Influence infrastructure decisions in a scaling startup where engineering excellence drives real-world impact

Technical Environment

• Backend: Node.js, TypeScript, PostgreSQL (SQL-first approach)
• Frontend: React, MUI, GraphQL
• Infrastructure: GCP, Infrastructure as Code (Pulumi), Graphile Worker

Engineering Philosophy:

• Automated testing is non-negotiable (Jest, e2e, CI/CD pipelines)
• Prioritise maintainability and scalability without over-engineering

Ideal Candidate Profile

• Senior Full-Stack Expertise: 5+ years with Node.js/TypeScript and PostgreSQL (React experience preferred)
• SQL Mastery: Schema design, query optimisation, and performance tuning
• Startup Proven: Successfully shipped and iterated on products in fast-paced environments
• Quality Advocate: Experience writing comprehensive tests and collaborating with QA processes
• Bonus point: Experience building AI agents

Differentiators:

• Familiarity with QA frameworks or test automation
• Background in regulated industries (healthcare, health-tech, fintech)
• DevOps
