Job description

Welcome to the good side of tech

You might know us as ZnanyLekarz in Poland or Doctoralia in Spain. Globally, we are Docplanner.

We build technology that helps people live longer, healthier lives. Our products connect patients with doctors, power clinical workflows, and support healthcare systems used by millions of people every month.

Engineering at Docplanner is about building reliable, scalable systems with real human impact. What we ship affects patients, doctors, and clinics in everyday, high-stakes situations - which means quality, judgment, and long-term thinking matter.

In 2026, we are accelerating delivery across multiple product areas by changing how we build - leveraging AI-assisted development to increase engineering effectiveness and raise the bar on how we design, ship, and evolve systems.

And why should you join us?

Because it feels good to tell your family and your friends how you made the world a little bit better. You go to bed knowing that what you do matters, and that your talents align with your beliefs.

We want to help people live longer, healthier lives, and that starts with you being you. We believe that taking the diversity of human experience into account makes a better healthcare experience for all . We’re not just different: we embrace diversity. We will encourage you to come to work your whole self. You can decide to work fully remote, or work hybrid with our offices located in Barcelona or Warsaw. This will be dependent on the final team allocation.

Our challenges

Our Engineers may join teams working on these areas and challenges:

Marketplace & Search

Build the next-generation marketplace system by owning the end-to-end journey from agentic discovery to rebooking. You’ll leverage AI search and AI onboarding funnels to unlock new demand and transform one-off bookings into continuous care loops.

Practice Management Systems (PMS)

Build the next generation of software to help doctors globally. Unify the current fragmented reality and leverage AI to reinvent the way to help doctors focus on what matters most: treating the patient.

AI-powered Clinical Tools (Noa Medic)

Design AI-native clinical workflows that move beyond simple scribing to replace end-to-end administrative tasks. You'll build deep PMS/EHR embeddings that become an indispensable daily habit for medical professionals.

Patient & Data Integrations (Noa Patient)

Move beyond the booking button to build a proactive healthcare partner. You'll create the smart connections that blend someone's medical past with their live health data, crafting an AI experience that actually keeps patients coming back. Turn raw data into advice people can use, making Docplanner the one health app they can't live without.

Internally, these challenges map to some of our most ambitious and high-impact initiatives.

How we build software

• We build systems that matter and we optimize for clarity, speed, and long-term maintainability.
• Small autonomous teams that own real product surfaces end-to-end
• High trust and high ownership from day one
• Production impact early - even as a junior engineer
• AI-assisted development as a default workflow
• Strong engineering culture focused on simplicity, correctness, and measurable outcomes
• We prefer solving problems well over adding unnecessary complexity.
• Good ideas win regardless of tenure or hierarchy.

What we value

Strong problem solving ability. The ability to break down complex systems and find elegant solutions.

Builder mindset. You like creating things that people use.

Intellectual curiosity. You enjoy understanding how systems really work.

Ownership. You treat problems as yours until they are solved.

Pragmatism. You know when to optimize and when to ship.

We value signals over credentials.

Competition programming, open-source work, research, side projects or anything else that shows how you think.

Technical Environment

• Our stack evolves continuously, but currently includes technologies such as:
• Backend: Node.js, TypeScript
• Frontend: React, TypeScript
• Mobile: React Native
• Infrastructure: AWS, Kubernetes, Terraform
• Developer tooling: modern CI/CD, observability
• AI-assisted coding environments built to scale (guardrails, rules, skills, subagents, spec-driven development)

We invest heavily in developer productivity and continuously improve how we design and ship systems.

Collaboration Model

• Open source internal culture - contribute across different services and teams
• Maintainer guidance rather than gatekeeping from senior developers
• Cross-functional ownership of features from conception to deployment
• Living documentation shared across all team members
