At Compodium, we build video meetings and communication solutions for organizations with high demands on security and regulatory compliance. That affects everything we do, from architecture and identity to how we ensure control of data at every step.
We develop reliable, user-friendly products that let customers collaborate and share information with confidence, without slowing down daily work.
Now we’re looking for a Senior Fullstack Developer who wants to help evolve both our platform and products in a company where technology, customer value, and long-term thinking go hand in hand.
As a Senior Fullstack Developer, you’ll work hands-on with both architecture and implementation, helping improve our video services and SaaS products. You’ll build product-focused solutions designed for environments with high requirements for stability, usability, and data control.
AI is a core part of how we build software. We expect you to actively leverage tools such as Claude Code, OpenAI Codex, Cursor, or similar, and to be skilled in context engineering and orchestrating agents to systematically improve architectural decisions, implementation speed, and code quality.
You will work on:
Video solutions based on WebRTC and MediaSoup
Modern web-based SaaS services
Improvements to scalability, performance, security, and UX
Automated flows for sign-up, onboarding, and online sales
Integrations with external systems, for example Stripe and eID services
Technically, we work with:
React and Node.js
PostgreSQL
Keycloak (identity and authentication)
Docker and Kubernetes
CI/CD and automation as a natural part of the workflow
You’ve built enough to know what holds up over time. You take ownership of the bigger picture, not just your part of the codebase, and you enjoy environments where technical decisions, structure, and product go hand in hand.
We believe you:
Have several years of experience as a fullstack developer
Are confident with Node.js and modern web applications, or have a strong backend background and want to work more fullstack
Have a solid understanding of security, performance, and scalability in distributed systems
Are used to container-based environments and see automation as the default
Are curious, pragmatic, and enjoy improving both code and ways of working
Right now, we’re modernizing our platform, building new modules, and scaling our SaaS offerings. You’ll have real influence on technical direction and help shape how the product evolves and is used.
