Application Engineer (F/M/X)

Location: Paris (75011)Contract: CDI (permanent), full-timeExperience: Entry-level (0–2 years, internships and apprenticeships included)Start date: ASAPWhy PROPHESEE?Prophesee is pioneering a new generation of machine vision inspired by the human eye and brain. Its breakthrough event-based vision technology enables machines to see and respond to changes with unprecedented speed and efficiency, serving demanding markets including industrial automation, aerospace and defense, autonomous systems, and IoT.You will join a unique technology adventure where you will turn our sensors into working solutions in our customers’ systems. As an Application Engineer in the Applications Engineering team, your work will have a direct impact on the success of one of the most promising Deep Tech companies worldwide.The teamThe Applications Engineering team is the technical bridge between our event-based vision sensors and the customers who build them into their systems, across industries including industrial automation, security and defense. We turn sensor capabilities into working solutions: we evaluate, prototype, implement and optimize side by side with our customers’ engineering teams. The position is based in our Paris office, with labs on site.MissionWe are looking for an entry-level engineer to join the team as an Application Engineer with a focus on software and computer vision, primarily for industrial applications. The role sits at the intersection of customer engineering, application development and rapid prototyping: you will build demonstrators and proofs-of-concept, write vision software that runs on real hardware, and support customers’ technical evaluations through to integration.This position is ideal for a recent graduate with a broad technical foundation (software, optics, electronics, physics) who is strongest in software and computer vision and genuinely enjoys hands-on work. You will be the person who sets up the camera, writes the processing pipeline, tunes the lighting, collects data, debugs what goes wrong and explains the result clearly. Working alongside senior Application Engineers, you will quickly gain autonomy on customer cases and feed what you learn in the field back into our products. The role involves regular travel to customer sites and events, in France and internationally (approximately 25–40% of the time).Role description1. Prototyping and proof-of-concept developmentBuild proof-of-concept demonstrators and prototypes that show what our sensors can do in concrete customer use cases, from first idea to working setup.Write, test and optimize software in C++ and Python for data acquisition, event and image processing, and computer vision algorithms.Assemble and adapt practical test setups (sensors, optics, lighting, mounts, embedded boards) and iterate quickly based on results.Turn successful prototypes into reusable sample code, tools and demo applications for the wider team and for customers.2. Customer engineering and technical supportSupport customers during evaluation and integration: set up evaluation kits, answer technical questions, and troubleshoot software, data and system-level issues.Join customer meetings and site visits to run demonstrations, capture recordings and test data, and validate system performance in real-world environments.Analyze application requirements such as speed, latency, dynamic range, resolution and field of view, and help recommend the right sensor, optics and software configuration.Reproduce customer issues in the lab and propose solutions involving processing pipelines, algorithm tuning or setup changes.3. Cross-functional collaborationWork with Sales and senior Application Engineers on the technical side of new opportunities.Share field feedback, recorded datasets and lessons learned with application development and product teams to improve our tools and inform the roadmap.Document recurring customer challenges, proven solutions and best practices in the internal knowledge base.Key deliverablesWorking prototypes, demo applications and proof-of-concept code, with clear documentation of setup and results.Technical reports from evaluations and customer visits, including measurements, findings and recommended next steps.Application notes, tutorials and training material for customers and internal teams.Live demonstrations and technical presentations for customer workshops and trade shows.Performance indicatorsCustomer evaluations supported and successfully converted to the next stage (design-in, project).Time to deliver a working proof-of-concept or demonstrator.Customer issue resolution time and customer satisfaction.Reusable assets produced (sample code, tools, application notes, knowledge-base articles).Quality of field feedback shared with product and development teams.ProfileEducation: Master’s degree (engineering school or university) in computer science, computer vision, electrical engineering, physics, mechatronics or a related field.Experience: entry-level; internships, apprenticeships or substantial academic projects count as relevant experience.Expertise & experience – requiredSolid programming skills in C++ and/or Python, with hands-on image processing, computer vision or data acquisition projects.Familiarity with core computer vision concepts such as filtering, segmentation, feature detection, tracking or camera calibration.Broad technical curiosity, with foundational knowledge in areas such as optics, image sensors and cameras, signal processing or embedded systems.Willingness to travel to customer sites and events, in France and internationally (approximately 2–3 trips per month).Expertise & experience – preferredExperience with OpenCV or similar computer vision libraries; exposure to deep learning frameworks such as PyTorch, or to ROS.Personal, academic or internship projects involving cameras, robotics, drones or other hardware prototypes.Interest in or exposure to event-based vision, neuromorphic sensing or high-speed imaging.Familiarity with embedded platforms (e.g. Linux-based boards), sensor interfaces such as MIPI CSI-2, or development tools such as Git, CMake and Docker.An internship in a semiconductor, imaging or optics company.Soft skillsA practical, hands-on mindset: you like building things, getting hardware up and running, and debugging problems end to end.Customer orientation: you want to understand customers’ needs and constraints and turn them into working solutions.Communication: ability to explain technical topics clearly to different audiences, from engineers to business stakeholders.Eagerness to learn, autonomy and pragmatism, with a “can do” attitude, even outside the well-known realm.Team player, comfortable in a fast-changing environment and passionate about technology.LanguagesEnglish: clear written and spoken communication in an international context – required.French: strongly appreciated, though not mandatory.Don’t tick every box?
