HMI Designer, Mission Interface & Autonomous Systems

Mirai Robotics

Mirai is building the first AI‑driven autonomy platform for vessels under 100 ft, combining advanced robotics, sensor fusion, and onboard intelligence to make every boat autonomous, safer, and dramatically easier to operate. Beyond enabling crewed vessels, Mirai also develops next‑generation Autonomous Surface Vehicles (ASVs) — uncrewed platforms designed for exploration, utility missions, and operational support — all powered by the same Operating System and multi‑layer autonomy framework. Imagine orchestrating a fleet of autonomous vessels running complex, coordinated missions across open water — no crew, no manual override, just the intelligence you built making decisions in real time. Multiple robots, multiple objectives, degraded comms, dynamic conditions. The backend that makes that possible doesn't exist yet. You'd be building it. We are seeking a hands-on developer to join our mission systems team. In this role, you will spend most of your time writing code — designing and building the server-side infrastructure that connects our autonomous vehicles to the operators who command them: real-time telemetry pipelines, mission planning and tasking backends, command and control services, and the APIs that tie the entire stack together. This is not a CRUD application, and this is not an architecture role. The systems you build run on vessels operating at sea, in degraded network conditions, where latency costs missions and downtime is not an option. You will own what you ship, end to end. We are looking for the kind of developer who treats AI-assisted development as a core competency — Cursor, Copilot, Claude, whatever gets the job done — and uses it to ship robust, production-grade software faster than anyone around them. At Mirai, AI-augmented development is not a bonus skill. It is how we build. KEY RESPONSIBILITIES Real-Time Communications Design and implement low-latency communication layers between autonomous vehicles and ground systems using WebSocket, MQTT, gRPC, and similar protocols. Build robust message delivery and fault-tolerance mechanisms that hold up under intermittent connectivity and bandwidth constraints typical of maritime environments. Mission Planning & Command and Control Build backend services for mission planning, tasking, and real-time vehicle command across multiple concurrent autonomous platforms. Develop the logic that translates operator intent into actionable instructions for the autonomy stack. Data Pipelines & Telemetry Architect and maintain high-throughput ingestion pipelines for sensor telemetry, vehicle state, and mission data streaming from vessels in the field. Design storage and retrieval systems optimized for time-series and geospatial data. API Design & Systems Integration Define and maintain clean, versioned APIs for integration with HMI layers, internal services, and external platforms. Own the contract between backend services and the rest of the Mirai stack — robotics middleware, mission display, data archive. REQUIRED QUALIFICATIONS Being the kind of engineer who has already integrated AI tools into their daily development workflow — Cursor, Copilot, Claude, or whatever gets the job done — and considers this a professional baseline, not an experiment. 2–4 years of professional experience in backend or full-stack software engineering. Strong proficiency in at least one server-side language (Python, Go, Rust, or equivalent) and the pragmatism to pick the right one for the problem. Hands-on experience with real-time communication protocols (WebSocket, MQTT, gRPC, or similar). Solid understanding of distributed systems fundamentals — fault tolerance, consistency trade-offs, service reliability. Experience designing and documenting APIs consumed across multiple clients and teams. EU passport (or unrestricted right to work in Italy). This role supports hybrid work. PREFERRED QUALIFICATIONS Experience with time-series databases (InfluxDB, TimescaleDB) or geospatial data systems (PostGIS, similar). Familiarity with robotics middleware — ROS2, MAVLink, or similar protocols — or prior exposure to autonomous systems, UAV, or maritime platforms. Experience working with edge systems or constrained-bandwidth environments. Solid CI/CD practices, containerization, and cloud-native infrastructure experience. Open-source contributions or a personal technical portfolio that shows how you actually build things. WHAT WE OFFER Work on the most advanced autonomous maritime platform in Europe. Direct ownership of mission-critical backend infrastructure — systems that operate on real vessels, in real conditions. Fast engineering culture where AI-augmented development is the norm, not the exception. Hybrid role with flexibility on location once established in the team. The technical scope and responsibility to grow significantly as Mirai scales. JOIN US If you want to build robots that operate in the wild, Mirai is the place to grow.

Harmattan AI

ABOUT US Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE We are seeking a highly skilled Front-End Engineer to join our C2 Core team in Paris. In this role, you will be responsible for the operator's viewport into the battlefield, building the Human-Machine Interface (HMI) for our tactical Command and Control (C2) system. You will enter a context where cognitive load management is just as critical as software performance. The UI you build will run on tactical PCs in the field, requiring seamless real-time updates for the Common Operational Picture (COP), rendering multiple live video streams, and providing an intuitive interface for planning missions and commanding a fleet of robots. Responsibilities * COP Visualization: Build interactive maps and 2D/3D geospatial overlays displaying real-time robot telemetry, sensor data, and mission routes. * Real-Time Video Grid: Develop a low-latency, resilient video player interface capable of handling multiple simultaneous streams without freezing the main UI thread. * Mission Planning & Command: Create interactive tools for operators to draw waypoints, set mission parameters, and issue instant commands to the fleet. * Performance Architecture: Design a state management system capable of processing high-frequency data from the backend bus without causing UI jitter or memory leaks. * Collaborative Development: Work closely with UX/UI designers, backend engineers, and mission planning algorithm designers to refine workflows and ensure absolute minimum clicks for the operator. * Optimisation: Ensure the UI maintains strict performance benchmarks, such as consistent 60fps rendering, even during high-frequency map updates. CANDIDATE REQUIREMENTS * Educational Background: B.S. or M.Sc. in Computer Science, Software Engineering, or a related field. * Professional Experience: At least 5-6 years of experience shipping production-grade web applications with complex data visualisation. Technical Expertise: * Deep understanding of complex state management and real-time data flow. * Experience with geospatial mapping libraries (e.g., Mapbox, Leaflet, Cesium) or rendering APIs (WebGL, Canvas). * Familiarity with modern frameworks like React or Vue. * Domain Knowledge: Previous experience in defense, aerospace, fintech, or high-reliability domains where real-time data rendering is critical. * UX & Cognitive Load Awareness: High degree of user empathy; ability to design interfaces for high-stress environments where operators cannot afford distractions or confusing error states. * Proven Leadership & Ownership: A "mission-driven" and "product-oriented" mindset with a willingness to take full ownership of the frontend architecture. * Adaptability: Ability to thrive in a fast-paced, multi-disciplinary startup environment. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
