Edge Software Security Engineer

Tampere, Turku, Oulu, Helsinki · Hybrid

Company

NestAI is a European AI lab for defence delivering the adaptive operating system for modern battlefield operations. We develop adaptive intelligence for unmanned and command systems: AI that continuously learns from operational data and adapts to changing conditions.

NestOS is our open, modular and interoperable platform that 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 brings together over 200 engineers and scientists and partners with leading European defence forces and industry.

Role Description

Join the NestAI Edge Software team building secure software for unmanned and command systems. You will help design and implement how devices, services, operators, and connected products are trusted throughout their operational lifecycle.

Your work will cover secure deployment, fleet and asset management, communications, ground-control applications, and secure interoperability between systems. This is a hands-on product engineering role with primary focus on embedded and mobile devices.

Day-to-Day Responsibilities:

  • Design secure identity and access methods for devices, services, operators, and connected systems.
  • Define how assets are securely enrolled, deployed, updated, monitored, and retired.
  • Help establish secure communication, authorization, audit trails, and protection for sensitive interfaces and media services.
  • Secure structured operational data as it moves between system boundaries.
  • Ensure data origin, context, authority, timing, and traceability are preserved and cannot be silently or maliciously altered or replayed.
  • Apply validation and clear trust rules so malformed or untrusted data cannot trigger sensitive actions.
  • Review and improve protection against untrusted input, compromised devices, and misconfigured deployments.
  • Build security checks, operational guidance, and incident support with partner teams.

Qualifications:

  • Strong hands-on software security or platform security engineering experience.
  • Experience with device identity, access control, secure communications, or service lifecycle management.
  • Experience securing system integrations, data provenance, validation, or interoperability is valuable.
  • Proficiency in at least one modern programming language in embedded or mobile software development (C++, Python, Kotlin or equivalent) and experience with Linux, networking, and deployment automation.
  • Experience with embedded devices, robotics, mobile applications, cloud services, or fleet management is valuable.
  • Able to ship practical improvements under deadline and explain trade-offs clearly.
  • Experience in defence or other mission-critical systems is valuable

Build the systems that protect what matters most

Battlefields evolve faster than the systems built to counter them. European defence needs AI that keeps pace with threats and remains under sovereign control. That technology largely doesn't exist yet, and NestAI is building it.

For our people, that means working on problems that are genuinely novel, on systems that carry real weight. If you want your work to matter beyond the screen, this is where that work happens.

The adaptive operating
system for modern battlefield operations.

Edge delivers autonomy for unmanned platforms in signal-denied, GPS-denied environments. Core is the command and control and orchestration layer that fuses multi-sensor data into a unified operational picture. Engine runs across both, continuously turning operational data into deployed intelligence and keeping capability current as the battlefield changes.

Partners across European defence forces and industry are already building on it.

Ownership is the expectation

Ownership at NestAI is not a talking point. It is how the company operates. You take responsibility for outcomes, make decisions with imperfect information, and adapt when the ground shifts. The work is demanding and the pace is high - because the problems we solve require it.

It is not always easy, but it’s deeply rewarding.

“We develop technology that has to keep evolving, because the adversary evolves too. It's a constant cycle of adaptation and counter-adaptation. You never run out of things to do.”
