Full-Stack Developer (Lisbon)
Confirmed on the employer's own hiring board on Oct 17, 2026. First seen by Alion on Dec 1, 2025. Reaktor scores B on the Alion truth index.
Reaktor's award-winning tech community is looking for a Lead Developer to join us in Lisbon.
If you are in your element with a full software development cycle, have a passion for solving human problems with a holistic approach, and are curious to experience working in a low-hierarchy environment, you might just be what we're looking for.
As a Full Stack Developer at Reaktor, your job is to be an expert in a range of software development responsibilities spanning the entire software development lifecycle, from front-end to production.
Your daily tasks include:
Working together with the client’s technology and business teams and helping them pick the right technologies suitable for their needs
Implementing new features that require changes to front-end applications, back-end servers, and/or databases, even on infrastructure
Delivering the client and the team with world-class technical expertise
Other software development-related tasks, such as debugging, designing, and participating in creating the architecture
You are a curious-minded Developer who is comfortable working on both the back-end and front-end of an app and understands the role of infrastructure in everyday tasks.
To thrive in this position, you’ll need:
Experience in a broad range of software development modalities (backend, frontend, ops, and consulting skills).
We don’t have a hard limit with years of experience, but we’ve noticed that Full Stack competencies often take 6+ years to accumulate.
Previous experience with at least one common server-side programming language. Currently, many of our projects are built with TypeScript/JavaScript and Node.js. But, Java/Scala/Kotlin, Clojure, and Python are also used.
Strong knowledge of at least one common client-side language and framework. We often use TypeScript/JavaScript and React on our web app projects and Swift, Java/Scala/Kotlin, or TypeScript/JavaScript React-native on mobile.
Relevant skills to create new backend services and build CI/CD pipelines when the project requires.
Foundational knowledge in DevOps, including Continuous Integration (CI), automated deployment, and test automation
Know-how on databases (e.g., PostgreSQL).
To be comfortable engaging with the client stakeholders when needed.
Fluent verbal and written English to collaborate in an international environment.
To be willing to work in a hybrid setup, where you work with your team at the office or the client's premises.
Why join us?
For two decades, we’ve been developing qualities and capabilities for adapting, reacting, and supporting change - building Reaktor to hold up in a fast-paced environment while ensuring the well-being of our people.

A community with as much support as your heart desires
A team that’s not only experienced but considerate as well - they all want you to succeed
