Description

About Skylo Skylo is a global Non-Terrestrial Network service provider based in Mountain View, CA, offering a service that allows smartphone and IoT cellular devices to connect directly over existing satellites. Skylo’s direct-to-device service is now live on millions of activated devices across five continents, with more than 60 million square kilometers of coverage, in partnership with multiple satellite operators, mobile network operators (MNOs), Tier-1 chipset makers, and OEMs. Devices connected over satellite are managed and served by Skylo's commercial NTN vRAN, featuring a 3GPP standards-based cloud-native base station and core. Skylo provides anywhere, anytime connectivity solution that seamlessly roams between terrestrial and satellite networks. Our focus is on enabling connected services for people outdoors and connected workflows across three main verticals: mass-market consumer devices, automotive, and industrial IoT. This role is located in Espoo, Finland. Summary Of How You Will Impact Skylo Skylo is hiring a Senior System Test Automation Engineer 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 a scalable, end-to-end test automation framework for our 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. We are not looking for someone who can just write tests under existing frameworks; we need an architect who can proactively engage with different teams, understand the network's intricate workings, and determine the right tools and design for a given test to achieve desired objectives. You must have extensive knowledge and experience implementing test automation with Robot Framework and writing custom keyword libraries in Python. Conduct Manual Testing and Derive Requirements: You will be able to perform manual tests in complex environments with physical devices and simulators to understand network behavior and derive robust test requirements at the planning stage. Drive Quality Assurance Processes and Standards: You will translate requirements from design and product definition documents into comprehensive test cases with scalable reporting structures. You will also define and enforce the standards for a successful QA function. Design, Develop, and Maintain Core Test Suites: You will design, develop, and maintain functional, regression, integration, and end-to-end tests for our system. You will proactively identify areas for automation and create, execute, and maintain automated test suites. This includes developing tests for performance, chaos, and fault injection, and enhancing existing regression testing 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. What We Look For 5-7+ years of direct experience in software quality assurance / software development in test, with a focus on test automation. Solid experience designing and building test automation frameworks from scratch, particularly for complex, end-to-end networks - it is not sufficient just to have used automation developed by others. Minimum of 5 years relevant experience in the areas of DevOps engineering and/ or Software build and release engineering. Extensive knowledge of and experience with implementing test automation with Robot Framework, including writing keyword libraries in Python. Deep understanding and direct experience with QA processes and standards, including translating product requirements into test cases and defining success metrics. 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. Working knowledge of cloud infrastructure, in particular AWS and GCP. Experience with automation test tools like Jenkins, Git, GitLab, and Artifactory, and an understanding of how they enable the CI/CD pipeline. Experience with Linux and Docker. Experience with integration of tests into Jenkins pipelines (declarative or scripted). Knowledge of Ansible or Terraform is a plus. Proven ability to be proactive, independent, and work collaboratively with cross-functional teams in a fast-paced environment. What We Offer 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: Competitive compensation packages including a stock option based equity program Comprehensive benefits plan Monthly allowances for wellness and education reimbursement A generous time off policy, holidays, and the opportunity to temporarily work abroad Once in a lifetime opportunity to be a part of developing and running world’s first commercial, live direct-to-device satellite network and service Access to world-class team and talent across tech domains: software, hardware, chipsets, telecom, satellite and network virtualization Open, transparent, inclusive culture that blends the Silicon Valley, Nordic and South Asia characteristics EEO Statement Skylo is an equal-opportunity employer and we celebrate diversity.
