Test Automation / Integration Release Engineer

Company

NestAI builds the adaptive operating system for modern battlefield operations. Most AI systems are built once, validated at deployment, and expected to stay sufficient after that. That assumption holds until conditions change, and in defence, they always do. Our team develops adaptive intelligence for unmanned and command systems: AI that continuously learns from operational data and adapts to changing conditions, deployed in environments where there is no internet, no GPS, and failure is not an option. NestOS, our open, modular, and interoperable platform, enables this at scale and keeps capability evolution under sovereign European control.

Founded in 2025 by Peter Sarlin, whose previous company Silo AI became Europe's largest AI acquisition, NestAI has grown to over 200 engineers and scientists and partners with leading European defence forces and industry. We're ambitious about what we're building and honest with each other. The bar is high, and so are the standards we hold ourselves to. But this is also a place built on humility, trust, and looking after each other. If that sounds like the kind of work you want to do, keep reading.

Role Description

You’ll join our forward deployment engineering team as a Test Automation / Integration Release Engineer, working directly inside customer projects to make sure the software we ship holds up where it matters: integrated into live customer environments, running on real platforms, under real operational conditions.

You’ll own test automation, CI/CD quality gates, and the use of AI agents and copilots to scale test coverage and catch regressions fast. You don’t need to be a hardware or embedded specialist, but you should be comfortable enough with the edge/embedded side of the stack to understand how your tests interact with real hardware, spot when a failure is software versus hardware, and work credibly with the engineers who own that layer.

Day-to-day Responsibilities

• Work embedded within a customer project as part of our forward deployment engineering team, owning software quality and test automation directly within that environment.
• Build and mature automated test suites and CI/CD quality gates to support rapid, reliable delivery cycles for software deployed to customer platforms.
• Use AI agents and copilots to scale QA coverage: generate test cases, automate triage, and accelerate regression testing.
• Work with hardware/embedded engineers to understand how software integrates with the underlying platform, enough to triage whether an issue is software or hardware, without needing to own the hardware layer yourself.
• Diagnose and help resolve integration and quality issues directly within the customer environment, closing the loop quickly between what’s seen in deployment and what gets fixed upstream.
• Take direct ownership of quality issues as they surface. Prioritise, investigate, and dive into solving problems directly rather than waiting for someone else to do it.

Qualifications & Experience

• Solid experience in software QA/test engineering for complex systems, including test automation and CI/CD quality practices.
• Practical experience using agentic AI tools or copilots to generate tests, automate workflows, or otherwise improve testing efficiency.
• Basic working understanding of embedded, edge, or hardware-integrated systems — enough to reason about software/hardware interaction.
• Willingness and ability to work embedded within customer projects.
• A proactive “get-it-done” attitude with a preference for diving in and building clean solutions, often with limited direct support.
• Proficiency in Python with working knowledge of CI/CD and modern build infrastructure tooling.
• Strong communication skills, comfortable working directly with customer stakeholders as well as internal engineering teams.

Why join NestAI

At NestAI, you’ll build meaningful, real-world technology as part of a world-class team of engineers, scientists, and experienced professionals. You’ll work on systems where reliability genuinely matters, contribute to Europe’s security and resilience, and solve problems that demand depth, trust, and craftsmanship.

If you want to build with purpose - and with leading experts in the field - you’ve come to the right place.
