  • A track record of owning features from design through deployment and operation, with hands-on experience in Docker, Kubernetes, CI/CD pipelines using GitHub Actions, and Linux (Ubuntu).

Nice to have

The role

Sateliot is a Barcelona-based satellite company with one goal: connect everything, everywhere. Founded in 2018, we've built the first satellite constellation that lets standard commercial devices communicate directly from space. Our technology bridges the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet.

What you'll do

  • Design and deliver full-stack features end to end, from technical design through Laravel/PHP and Python APIs to React and Angular web interfaces, with minimal supervision.

  • Set the quality bar for the team: drive unit testing and code quality with SonarQube, meaningful code reviews, maintainability standards, and pragmatic technical-debt management.

  • Own technical design and architecture decisions for reliable tools and dashboards that integrate data from across the company (Core Network, Platform), documenting key trade-offs and helping evolve the platform.

  • Mentor less experienced engineers through pairing, code review, and design discussions, raising the team's level through your work and experience.

  • Operate what you build in production, working with IT Platform on deployments.

How you'll work

  • Based in Barcelona, with on-site presence under our hybrid model (3 days on-site / 2 remote).

In their own words

About the company & team

The Full Stack team builds the web applications and APIs that turn Sateliot's network data into tools our internal teams rely on every day, from device status and tracking to session and satellite pass management.

As a Senior Full Stack Engineer, you'll own features from design to production across a Laravel (PHP) and Python codebase, set the bar for quality in a small team, and partner closely with 4G/5G Core Network and IT Platform to surface their data and controls.

We're looking for someone who has already shipped and operated production systems, raises the level of the people around them, and thrives with autonomy in a high-trust environment.

We lead with humility, move fast, and take ownership. We collaborate without ego and measure ourselves by real impact, not titles or hierarchy. We hire people who already live these values.
