About marta
At marta, we build technology that makes high-quality home care accessible, transparent, and human. Our platform connects families and caregivers across Europe, creating trust, dignity, and simplicity in one of the most essential industries: elderly care.

After establishing ourselves as the technological leader in the live-in care market, we are now entering the next growth phase — scaling our product and engineering organization to deliver greater speed, stability, and impact. Our goal is clear: to set the new standard for technology in elderly care.

Your Role in our team

Your Mission
You ship reliable, maintainable, and high-impact code — fast. You take full ownership of the features you build, from first idea through implementation, testing, documentation, and production rollout. You work closely with the Engineering Lead and Product Lead to translate business problems into simple, stable solutions across marta’s multi-service architecture.

Key Responsibilities

1. End-to-End Feature Delivery

• Build high-quality features across backend and frontend using TypeScript, Node.js, and React.
• Translate product requirements into clean, maintainable implementations.
• Take full ownership of your code — from design to testing to observability.
• Ensure features include regression tests and predictable behavior under load.

2. Work Deeply in Our Architecture

• Contribute to core services across 9 microservices and multiple apps.
• Help simplify and consolidate the system where possible (e.g., monorepo adoption, shared library improvements).
• Maintain predictable APIs, clear data flows, and stable interfaces.

3. Fast & Lean Engineering

• Deliver quickly without compromising quality — lean, simple, pragmatic solutions.
• Identify unnecessary complexity and reduce it.
• Write code that others can understand and build upon.
• Use AI tools to accelerate documentation, scaffolding, and test creation.

4. Ownership & Security

• Break down features into clear, executable tasks.
• Give constructive feedback early when requirements are unclear.
• Align with Product on feasibility and necessary trade-offs.
• Build secure-by-default components and handle data with care.
• Assist in improving reliability, monitoring, and incident response.
• Follow CI/CD processes and avoid untested changes or hotfix shortcuts.

Your Profile

You are a great fit if you:

• Have 5–10 years of experience building production-grade systems.
• Write fast, clean, and maintainable code in TypeScript, Node.js, React.
• Understand backend fundamentals: Hexagonal Architecture, NestJs/Inversify, Express.js, AWS SQS/SNS, Sockets, PostgreSQL, TypeORM.
• Know your way around AWS (ECS/EKS), Docker, Kubernetes, Terraform.
• Have experience with CI/CD pipelines (GitHub Actions, CircleCI).
• Work pragmatically: prefer simple solutions over abstractions.
• Care deeply about testing and long-term reliability.
• Take ownership of what you build — even after it ships.
• Communicate clearly with engineers, product managers, and designers.
• Enjoy working in a lean, fast-moving team with minimal hierarchy.

Nice to have

• Experience with observability (Prometheus, Grafana, Sentry).
• Prior work in distributed systems or microservices.
• Experience with AI-assisted development workflows.
