Alta Ares is a deeptech startup founded in 2024, building real-time AI for defense operations — ISR, C-UAS, and autonomous systems. Our clients are NATO-aligned militaries and defence institutions, with regular deployments during live exercises and operational demonstrations. We raised €2M seed in May 2025, 50M in June 2026, and are expanding fast.
Our product suite includes:
Real-time AI ISR module deployable on drones and tactical platforms
Counter-UAS solution enabling autonomous drone takeover in GNSS-denied environments
Full-stack MLOps platform for training & deploying military-grade AI models
Data fusion and trajectory prediction
As a Front-End Engineer, you will own the development of high-quality interfaces across our software platforms (cloud, on-premise, and edge deployments) with a strong product-vision.
While your core strength is front-end engineering and design systems, you are comfortable contributing beyond the UI layer working with APIs, backend services, and system integrations when required. We are a small and agile company, requiring flexibility.
This role is ideal for engineers coming from SaaS or scale-up environments who combine frontend craftsmanship with product ownership and versatility.
Consolidate existing software products and lead cross-products code refactors when needed
Build scalable, maintainable web applications using modern frameworks
Develop and maintain a coherent design system and reusable component library, in collaboration with our UI/UX designer
Ensure high standards of UX, consistency, and visual quality across products
Build applications that run across cloud, on-premise, and edge environments
Handle diverse data patterns (real-time, batch, intermittent connectivity)
Ensure resilience and usability in constrained or operational contexts
Optimize frontend performance and application responsiveness
Ensure reliability in mission-critical environments
Debug production issues across the stack when necessary
Integrate with backend APIs and data services
Contribute to backend or middleware when needed (API design, data handling, debugging)
Work across the stack to unblock progress in a small, fast-moving team
Write unit, integration, and end-to-end tests
Maintain high standards of code quality and documentation
Participate in code reviews and continuous improvement
3–5 years of experience in software engineering, with strong frontend specialization
Proven experience in SaaS or scale-up environments
Strong expertise in modern frontend frameworks (React preferred)
Solid understanding of design systems and UI architecture
Comfortable working across the stack (APIs, backend basics, system integration)
Product-oriented mindset with a bias for action
Experience with data-heavy or complex interfaces
Familiarity with applications deployed outside standard cloud environments (on-prem, edge)
Experience with TypeScript across the stack
Exposure to DevOps or deployment pipelines
Interest in deeptech, defense, or high-reliability systems
Frontend Craftsmanship
Versatility
Product Ownership
Execution & Autonomy
