Senior Software Development Engineer in Test

The world still has coverage blind spots. You could help eliminate them at Skylo.

Skylo has pioneered a standards-based approach to satellite connectivity. We connect smartphones and IoT devices directly to satellites. No special hardware, no entirely new networks. Just billions of existing devices, suddenly reachable anywhere on Earth. We're not building toward this future. We're already in it.

Our direct-to-device service is live on millions of activated devices across five continents, covering more than 72 million square kilometers, in partnership with leading satellite operators, mobile network operators, Tier-1 chipset makers, and OEMs worldwide. And we're just getting started.

At the heart of it all is Skylo's commercial NTN vRAN: a 3GPP standards-based, cloud-native platform that seamlessly bridges terrestrial and satellite networks. It's the infrastructure that makes true anywhere, anytime connectivity possible.

When you join Skylo, you'll work at the intersection of three markets reshaping how the world stays connected: mass-market consumer devices, automotive, and industrial IoT. Enabling people outdoors and critical workflows in the world's most remote places.

This is a rare chance to work on technology that matters, at a company that's already proving it works

This role is based in Espoo, Finland, one of the three Skylo's core engineering hubs and fastest-growing sites. You'll work onsite three days a week as part of a team that's scaling quickly.

How You Will Impact Skylo

Skylo is hiring a Senior Software Development Engineer in Test to help us fulfill our mission of making satellite connectivity available to all. As a key contributor to the System Test team, you will serve as a quality gatekeeper for the company. Your primary responsibility will be to design, build, and maintain scalable, end-to-end test automation frameworks for our 4G/5G-based network. You'll play a crucial and proactive role in validating the quality of our releases and preventing defects from reaching production.

How You Will Contribute

• Architect and Build Scalable Automation Frameworks from Scratch: You will be a hands-on engineer responsible for designing and building test automation frameworks from the ground up for our complex, end-to-end 4G/5G Non-Terrestrial Network. This means proactively engaging with different teams, understanding the network's intricate workings, and determining the right tools and design for each test to achieve the desired objectives — not just writing tests under existing frameworks.

• Design, Develop, and Maintain Core Test Suites: You will design, develop, and maintain functional, regression, integration, acceptance, and end-to-end tests for Skylo's NTN network. You will proactively identify areas for automation and create, execute, and maintain automated test suites.

• Integrate with CI/CD Pipelines: You will implement and maintain test automation within a continuous integration/continuous delivery (CI/CD) pipeline using Jenkins to ensure quality at every stage of the development lifecycle.

Sound like you? You bring:

• 5-7+ years of direct experience in software development in test

• Solid experience designing and building test automation frameworks from scratch, particularly for complex, end-to-end networks  (Not sufficient just to have used automation developed by others.)

• Extensive experience with software development using Python - i.e., that goes beyond scripting

• Extensive experience with implementing test automation with Robot Framework, including writing keyword libraries in Python.

• Experience with automation test tools like Jenkins, Git, GitLab, and Artifactory, and an understanding of how they enable the CI/CD pipeline.

  • Experience with integration of tests into Jenkins pipelines (declarative or scripted).

• Experience with Linux and Docker.

• Proven ability to be proactive, independent, and work collaboratively with cross-functional teams in a fast-paced environment.

• Ability to hit the ground running / adapt and learn quickly

• Every role at Skylo uses AI tools daily to amplify output. We expect active habits using AI tools and a track record of folding new ones into your workflow quickly

Nice to have

• Direct experience working with or on a 4G/5G network, with a strong understanding of different network component functions, protocols, and their test automation, including 3GPP and NB-IoT protocols.

• Deep understanding and direct experience with QA processes and standards, including translating product requirements into test cases and defining success metrics.

• Working knowledge of cloud infrastructure, in particular AWS and GCP.

What We Offer

This is a once-in-a-lifetime opportunity to help build and run the world's first commercial, live direct-to-device satellite network. You'll work alongside a world-class team spanning software, hardware, chipsets, telecom, satellite, and network virtualization, some of the most sought-after expertise in the industry. And you'll do it inside a culture that's open, transparent, and inclusive, shaped by the best of Silicon Valley, Nordic, and South Asian ways of working.

With employees working across three continents, Skylo is proud to be an equal opportunity employer dedicated to building an inclusive and diverse workforce. Our worldwide and inclusive culture encourages a flexible approach to work, and we also offer an attractive range benefits such as:
