Our team consists of passionate professionals driven by a shared vision of creating a greener and more sustainable future through innovation, technology, and excellence.

We are processing vast data for Advanced Driver Assistance Systems (ADAS). We are looking for a UI Developer to join our team and be a key contributor to our mission. If you are passionate about electric vehicles, possess expertise in modern web interfaces, and have the ability to translate complex data into intuitive visual experiences, we invite you to apply. In this role, you will be instrumental in our electric vehicle and ADAS projects, using your skills to design and implement high-quality user interfaces for data analysis and visualization. You will collaborate with diverse teams, including Quality Control, UI/UX, Data Science, and Data Engineering, to create cutting-edge solutions that will drive the future of transportation.

Key Responsibilities

Coordinate with cross-functional teams (AI, ADAS, Systems, DevOps) to understand and

define software requirements and UI/UX design specifications.

Translate Figma design mockups into clean, high-performance, and responsive code with a

focus on pixel-perfect output.

Design and develop RESTful API integrations and architect front-end data models for realtime visualization (sensor data, images, point cloud, KPI dashboards, etc.).
Conduct thorough UI/UX reviews and participate in testing to ensure code quality, brand

consistency, and performance.

Develop and maintain Python-based API services (FastAPI/Flask) for the Data Platform:

ingestion, query, processing pipelines, metadata, KPI evaluation, etc.

Define API contracts together with other engineers, ensuring clear schemas, versioning, and

standard documentation (OpenAPI/Swagger).

Integrate AI/LLM solutions into internal systems to boost productivity for engineers and data

teams: natural-language data query copilots, semantic search over metadata, auto-tagging,

scenario summarization, LLM-powered in-UI assistants, etc.

Troubleshoot and resolve performance bottlenecks in both cloud (AWS) and on-premises

environments.

Maintain best practices for code quality, version control (Git), CI/CD, and system reliability.

Requirements

A minimum of 7 years of experience in software development, with at least 4 years of specializing in UI/Frontend.

Proficiency in at least one modern JavaScript framework (React or Vue); React is preferred.
Proficiency in design tools such as Figma, with strong attention to detail.
Proficiency in Python for backend development: Django or Flask, async programming, SQLAlchemy/ORM, and unit testing.
Experience working with SQL/NoSQL databases (PostgreSQL, MongoDB) and message queue/cache systems (Redis, Kafka is a plus).
Experience integrating with Backend APIs and working with public APIs (Google Maps, HERE Maps, etc.).
A portfolio demonstrating a commitment to pixel-perfect output, smooth animations, and clean, maintainable code.
Applied knowledge of AI/LLM for internal-facing features:
Solid grasp of core concepts: LLMs, embeddings, vector databases, prompt engineering, RAG, function calling, and agents.
Hands-on experience calling LLM provider APIs (OpenAI, Anthropic, or opensource models via vLLM/Ollama).
Ability to design product features that leverage LLMs for internal users: chatbots/copilots on internal data, semantic search, auto-tagging, natural language to query (SQL/API), in-UI operational assistants, etc.
Ability to work closely with backend and AI engineers to define API contracts and data

requirements.

Exceptional problem-solving skills and a knack for thinking outside the box to find

innovative solutions.

Nice To Have

Experience with WebGL or Three.js for 3D visualization (point cloud, 3D bounding boxes,

LiDAR/camera scene rendering) — a strong plus.

Experience with cloud platforms such as AWS or Azure (S3, ECS/EKS, Lambda, IAM, etc.).
Experience with containers and orchestration (Docker, Kubernetes).
Experience building production RAG pipelines (LangChain, LlamaIndex, or custom-built),

fine-tuning, or working with open-source LLMs.

Familiarity with MLOps or data pipelines (Airflow, MLflow) is a plus.
Experience building desktop UIs with PyQt or PySide.
Involvement in startup environments or a demonstrated willingness to thrive in a fast-paced,

entrepreneurial setting.

Strong interest in autonomous driving, ADAS, or computer vision.
