Nortal's Applied Defence R&D serves as an innovation engine, transforming complex defence challenges into validated, deployable solutions. By combining cyber resilience, AI, data science, embedded security, and digital engineering, we deliver mission-ready prototypes and architectures. Partnering with governments, armed forces, industry, and academia, we create sovereign IP, dual-use technologies, and NATO/EU-aligned innovations that reduce risk and accelerate capability delivery.
We are looking for a Security Engineer to support the design, development, and validation of secure hardware-based products and prototypes. You will work across hardware, firmware, and embedded software to build security in from early design through prototyping and testing, on a product with a real physical footprint rather than a purely digital one.
Key Responsibilities
- Contribute to security-by-design for hardware products, embedded systems, and integrated hardware-software solutions
- Perform threat modelling and security risk analysis for devices, components, interfaces, and firmware
- Define and implement hardware and firmware security controls, including secure boot, roots of trust, key protection, device identity, and secure update mechanisms
- Support secure hardware architecture and component selection from a security perspective
- Assess attack surfaces including debug interfaces, physical access, communications interfaces, and firmware update paths
- Plan and perform security testing, hardening, and validation of prototypes and product components
- Work with systems, software, electronics, and mechanical engineers to integrate security requirements into product designs
- Contribute technical content to R&D project deliverables, engineering reports, and test documentation
Methods & Approaches
- Hardware and embedded-system threat modelling and security architecture
- Secure development lifecycle practices for hardware, firmware, and embedded software
- Prototype security testing, vulnerability analysis, and hardware/firmware hardening
- Security requirements engineering and evidence-based validation
Deliverables
- Security requirements, threat models, and risk assessments for hardware products and prototypes
- Implemented hardware and firmware security mechanisms and configurations
- Security test plans, results, and mitigation recommendations
- Technical sections of R&D deliverables, engineering reports, and design documentation
Skills & Experience
- Strong background in cyber security, embedded systems, electronics, or secure product engineering
- Practical experience bringing hardware products or complex prototypes from design to tested implementation
- Understanding of embedded architectures, firmware, PCB-level interfaces, and hardware-software integration
- Experience with secure boot, hardware roots of trust, TPM/secure elements, cryptographic key handling, or secure firmware updates
- Experience using security testing and debugging tools for embedded or hardware systems
- Experience in defence, critical infrastructure, or multi-partner R&D projects is an advantage
- Relevant security or embedded-system certifications are a plus, not mandatory
Why Nortal?
- We hire people not only for their skills but also for cultural add. We live by our values: commit to delivering value and results, take ownership, empower yourself and others, and own your future and growth. Besides our professionalism, we like to spice things up with good humour
- We care about your growth & development. At Nortal, we support constant improvement and knowledge sharing
- We prioritise your health & well-being by providing a flexible package for health insurance and sports initiatives

- It's your choice whether you want to work from the office or remotely within Estonia
Salary range:
€4600-6500 gross/monthly (full-time).
Final compensation will depend on factors such as relevant experience, role seniority, and skill set.
