Our expertise covers full-cycle product development — from consulting and architecture to implementation and support — using modern technologies such as microservices, cloud infrastructure (AWS, Azure, GCP), and scalable distributed systems.
We actively work with emerging technologies, including IoT, AI, and real-time data platforms, and collaborate with innovative startups building next-generation products.
Project Overview
We are building a next-generation enterprise platform for real-time monitoring, interpretation, and optimization of indoor environments at scale.
The system processes data from multiple sources — including environmental sensors, occupancy tracking systems, and building infrastructure — combining edge computing and cloud data pipelines to enable near real-time insights and automation.
This is a production-grade platform, not a typical dashboard project. It includes:
Real-time data ingestion and streaming pipelines
Device and sensor integration (IoT)
Data normalization and orchestration layers
Time-series and graph-based storage
Digital twin and spatial data synchronization
Analytics dashboards and operational portals
Workflow automation and enterprise integrations
The platform is designed to support high data volumes, strict reliability requirements, and scalable multi-tenant environments.
Responsibilities
Design and develop backend services and APIs for real-time data ingestion, processing, and orchestration
Build and maintain user-facing portals and analytics dashboards using React
Integrate with external systems, devices, and data sources (IoT, APIs, streaming protocols)
Implement scalable and reliable data processing flows (event-driven / real-time)
Collaborate with cross-functional teams (data, AI, DevOps) on system design and delivery
Ensure code quality, performance, and maintainability in a production environment
Participate in architecture discussions and contribute to technical decision-making
Use AI tools to improve development speed, code quality, and documentation
Requirements
Strong experience with TypeScript, Node.js (or NestJS), and React
Solid backend development experience (APIs, services, system design)
Experience working with real-time or data-intensive systems
Familiarity with REST APIs, and ideally gRPC or event-driven architectures
Experience with PostgreSQL or other relational databases
Understanding of asynchronous processing and distributed systems
Ability to translate business requirements into scalable technical solutions
Good communication skills and ability to work in an international team
Nice to Have
Experience with MQTT, WebSockets, or streaming data systems
Exposure to time-series databases (e.g., InfluxDB)
Experience with graph databases like Neo4j
Experience with cloud platforms (AWS, GCP) and containerization (Docker)
Understanding of IoT systems or sensor data processing
Experience with multi-tenant applications
Highly Desirable (for selected candidates)
Experience with BIM / building data systems (Revit, Autodesk Forge, IFC)
Exposure to digital twin technologies or spatial data platforms
Familiarity with OpenUSD or similar frameworks
AI-related Requirements
Practical experience with AI development tools such as GitHub Copilot, ChatGPT, Cursor, or similar
Ability to effectively use prompt engineering to accelerate development workflows
Understanding of AI limitations and ability to apply critical thinking
Experience using AI tools for debugging, refactoring, and improving code quality
Benefits
Work in a US-based company recognized among the top software development firms in Illinois
Flexible working conditions and fully remote setup
Competitive compensation aligned with international markets
Opportunity to work on a technically complex, large-scale platform
Professional growth, certification, and continuous learning support
Internal training programs (English, technical, and soft skills)
