(Senior) Forward Deployed Engineer

(Senior) Forward Deployed Engineer 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 150 engineers and scientists and partners with leading European defence forces and industry. Role Description We are looking for a Senior Forward Deployed Engineer (FDE) to join our team full-time in Stockholm, or with the ability to commute to Stockholm metropolitan area around 3 days per week. As a Senior Forward Deployed Engineer (FDE) specializing eiher in Artificial Intelligence, Embedded Systems or Full Stack Engineering , you manage the technical delivery and integration of NestAI’s autonomous systems for our partners. Embedded directly within key partner initiatives, FDE squads shorten the path from development to fielded capability, validating product features where assumptions are tested against operational reality. This is not a standard implementation role; it is a high-stakes engineering position where you tailor our platforms to the complex, real-world environments of our most critical partners. We are looking for a senior builder who understands that in mission-critical domains, "good enough" doesn't exist. You will bring a high degree of architectural depth to solve problems where software meets hardware in the physical world. Day-to-day responsibilities include: Mission-Specific Engineering: Technical leadership for client projects, taking full ownership of technical decisions to rapidly deploy and customize our platforms to specific client needs. Architectural Integration: Design, develop, and deploy solutions that connect edge devices, UAV sensors, and situational intelligence platforms into a cohesive operational picture supporting customer operating environments. AI-Driven Development: Utilize AI-driven development workflows to accelerate delivery cycles with our platforms without compromising the sovereign and reliable core of our systems. Collaborative Problem Solving: Work closely with client technical teams and internal product R&D to translate complex field requirements into scalable product features. Create rapid prototypes to explore future client aspirations. Technical Leadership: Act as the primary technical point of contact for customer engagements, providing the architectural "glue" between disparate data sources and decision-support interfaces. Qualifications Generalist Mindset & Adaptability: A versatile generalist profile; you enjoy changing scenery, adapt quickly to unfamiliar codebases, and feel comfortable operating across diverse technical ecosystems. A deep technical foundation and 5+ years of experience in at least one of the following: Cloud, AI, Edge/Embedded Computing, Machine Learning, or Data Engineering . A proven ability to think in "spatial" terms—understanding how AI interacts with physical environments and complex hardware architectures. You communicate fluently both in English and Swedish. You also have excellent interpersonal skills with the ability to confidently collaborate with external partners, translate business/operational needs into engineering reality, and lead client-facing deployments. Mindset: You thrive in "mission-first" environments and possess the Nordic engineering ethos of building systems that earn trust through performance, not promises. Ability to travel occasionally (up to 10% of worktime) to client sites within Europe to ensure field-proven performance. Pluses: Previous consulting or customer-facing engineering experience. Prior background in defence, aerospace, robotics, or related physical AI domains. 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. Practicalities Employment is subject to applicable security screening. NestAI is an equal opportunity employer. We consider all applicants based on their skills, experience, and potential. We are currently unable to provide visa sponsorship or international relocation support for this position. Candidates must already be based in Sweden or in the EU and have a valid work permit for this region at the time of application. Locations Sweden Remote status Hybrid Employment type Full-time About NestAI Physical AI is moving from theory to reality. The systems being built today will shape how societies protect people, operate critical infrastructure, and respond under pressure for decades to come. At NestAI, close to 200 engineers and scientists work at the intersection of software, hardware, and AI — developing autonomy, sensing, and command capabilities for mission-critical use. This isn’t demo work. It’s real systems, built for real environments. We build in Europe, with open and interoperable architectures, so that critical capabilities can evolve over time without lock-in — and remain accountable to the societies they serve.
