About Monaire
Monaire is building the infrastructure layer for intelligent commercial HVAC. We combine on-device sensors, smart thermostats, and machine-learning systems to automate control, surface real operational insight, and materially reduce energy waste at scale. This is not offline modeling or notebook ML. Models run in production, interact with physical systems, and must be observable, debuggable, and correct. The platform spans edge devices, cloud services, streaming pipelines, control logic, and ML inference.
Engineers here work on:
Data ingestion and streaming at scale from heterogeneous hardware
Low-latency decision pipelines and control loops
ML systems that survive missing data, drift, and adversarial real-world conditions
Infrastructure for model deployment, monitoring, and rollback
Apps and services that customers depend on to run their buildings every day
The market is large, broken, and technically underserved. We’re scaling the system and need engineers who care about correctness, performance, and ownership — people who want to build infrastructure that actually controls the physical world, not just dashboards that look good in demos.
Role Overview
As aData Scientist / Senior Data Scientist, you will play a critical role in buildingproduction-grade ML systemsthat drive real-world outcomes—energy efficiency, predictive maintenance, anomaly detection, and operational intelligence for HVAC/R systems.
You will work closely withbackend engineers, product managers, and domain expertsto translate raw sensor data into reliable models that power customer-facing features and internal decision-making.
This role requires someone who canthink long-term architecturally, while deliveringshort-term, measurable impactin a fast-moving startup environment.
What You'll Do:
Scale ML systems for 5X growth—optimize batch processing, database queries, and model inference
Design ML models for time-series data, anomaly detection, and predictive maintenance
Optimize production systems: <3s response times, 30% cost reduction, 99.9% uptime
Database optimization (MongoDB): indexes, connection pooling, 3-5X performance improvement
Batch processing: parallel processing, async operations, memory management
Model optimization: <500ms inference latency, caching strategies
NLP & LLM: enhance conversational AI bots with intelligent query generation
Build monitoring systems: real-time dashboards, SLA tracking, automated scaling
Requirements
Must-Have Skills
2+ years hands-on data science/ML experience
Strong Python (NumPy, Pandas, Scikit-learn)
Deep learning: TensorFlow, Keras, or PyTorch
MongoDB: Query optimization, indexing, aggregation pipelines
Database optimization: Index design, query tuning
Batch processing: Parallel processing (multiprocessing/async)

AWS: Lambda, S3, CloudWatch, ElastiCache/Redis
Docker, SQL, Flask API development
Qualifications
Bachelor's/Master's/PhD in CS, IT, Applied Math, Statistics, or related field
Benefits
Competitivesalary + equitywith meaningful ownership
Comprehensivehealth insurance(self, spouse, children, and parents)
Remote-first, flexible work culture
Opportunity to work onhigh-impact systems with climate and sustainability impact
Strong emphasis onengineering excellence, ownership, and growth
Collaborative, inclusive, and low-ego team culture
