About Alta Ares

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

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

Frontend \& Design Systems


  • 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

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
Requirements
----------------

Candidate Profile


  • 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

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

  • Interest in deeptech, defense, or high\-reliability systems

Skills \& Values

Frontend Craftsmanship

  • Strong attention to detail and UI quality

  • Ability to build scalable, reusable components
Versatility
  • Comfortable stepping outside strict role boundaries

  • Able to contribute across the stack when needed
Product Ownership
  • Focused on delivering user value, not just features
