About Alta AresAlta 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
- Role & Mission
- 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.
Your Responsibilities

- 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
- System Integration & Environments
- 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
- Performance & Reliability
- Optimize frontend performance and application responsiveness
- Ensure reliability in mission-critical environments
- Debug production issues across the stack when necessary
- Full-Stack Contribution
- 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
- Testing & Quality
- Write unit, integration, and end-to-end tests
- Maintain high standards of code quality and documentation
- Participate in code reviews and continuous improvement

- Nice to Have
- 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
