Your mission
We’re scaling our retail AI solutions after successful deployments across Germany, Europe, and the US. We’re looking for a *Full-Stack Engineer* to build the web applications and data infrastructure that power our computer vision solutions for retail environments.
You’ll work closely with our ML team (who handle the AI) and deployment team (who manage hardware), focusing on scalable web platforms and data pipelines that connect everything together.
Your tasks Full-Stack Development & Data Pipelines: - Build Flask-based web applications and RESTful APIs
- Create responsive front-end interfaces for B2B customers and internal teams
- Design data pipelines for processing computer vision outputs and customer analytics
- Develop customer-facing dashboards and reporting features
Enterprise Integrations:
- Implement enterprise IAM integrations (SAML/OIDC, Active Directory) for large corporate clients
- Build scalable backend services connecting edge devices to cloud infrastructure
- Collaborate with ML engineers to integrate and serve models effectively
Your profile
Core Requirements
1. Strong Python skills - our primary backend language
2. Web development experience - APIs, web apps, databases (SQL/NoSQL)
3. Data engineering mindset - experience with data pipelines or analytics
4. B.Sc./M.Sc. in Computer Science or 2+ years equivalent experience
5. Frontend & Full-Stack:
- React, Node.js, TypeScript
- Data visualization and dashboard development
Work Authorization:
- Valid work authorization for Germany required (German work permit)
Bonus Points
Pick your strengths - we don’t expect anyone to have all of these:
Data Engineering:
- Data pipelines, ETL processes, analytics platforms
- Stream/batch processing, pandas, data modeling
Enterprise & Platform:
- Enterprise IAM and authentication systems
- Docker, Kubernetes, cloud platforms (GCP, AWS, Azure)
- Infrastructure as code and DevOps practices
AI/Edge Integration:
- ONNX Runtime, NVIDIA DeepStream
- Video processing (GStreamer, FFmpeg)
- C++, CUDA programming
- Edge computing and embedded systems
Our Tech Stack
Languages: Python, C++, TypeScript, JavaScript
Backend: Flask, RESTful APIs, PostgreSQL, MongoDB
Frontend: React, Node.js
Infrastructure: Docker, Kubernetes, Linux, GCP
AI/Edge: ONNX Runtime, NVIDIA DeepStream, CUDA
Video: GStreamer, FFmpeg
What Makes You Stand Out
Full-stack mindset: You enjoy building end-to-end solutions from data pipelines to user interfaces.
Pragmatic approach: You balance technical excellence with shipping working solutions.
Collaborative spirit: You work well with ML engineers, product teams, and enjoy mentoring others.
Growth mindset: Interest in retail technology and AI applications, comfort in a fast-paced startup environment.
Problem-solving: Strong analytical skills and ability to work independently on complex technical challenges.
Language Skills
- Basic German language skills are preferred (A2 Level or higher)
What We’re NOT Looking For
- Someone who needs to be an expert in every technology listed
- Pure ML/AI researchers (we have that covered!)
- Backend-only specialists (we need full-stack capabilities)
- Someone who only wants to work on greenfield projects (we have real customers and real constraints)
About us
We are Signatrix, and together we are Remaking Retail. Our goal is to improve existing infrastructures and make them "smart" in a matter of weeks. Connecting with store security cameras, we use Artificial Intelligence to analyse whatever is happening in a store — automatically and in real-time.
