Job description

Spectral is seeking a talented Software Developer to join our core team. The role will involve working on overall software architecture and collaborating with the broader team across various applications and services. Activities will involve: development of the back-end and database layers (including data modeling, ORM implementation, and database optimization), building communication interfaces, data analytics and algorithm development, and integration with third-party systems.

The tech stack:
* Python
* Postgres
* TimescaleDB
* gRPC & Protobuf
* GitLab Pipelines
* Google Cloud Platform
* Kubernetes
* Docker
* RabbitMQ
* Vue.js, Javascript, HTML, CSS, The smart building platform is mainly developed in Python using various frameworks including Tornado, FastAPI, and gRPC. Data is drawn from multiple sources including the metering company's API, from the on-site sub-meters (using industry-standard protocols) and from external APIs (e.g. for weather data). Much of this data is stored in a TimescaleDB time-series database. Data visualizations and other UI elements are implemented in JavaScript-based libraries to deliver secure, permission-based content for different user roles (e.g. board member, property manager, tenant) including a tailored dashboard for each user type.

Sophisticated algorithms extract business intelligence and recommendations for energy savings, peak shaving, etc. Our solution provides sophisticated building portfolio analysis, including the ability to apply advanced data filtering and display or compare (aggregated) data for multiple locations. The reporting module gives full flexibility with regards to the selected data and templating. The smart building platform enables automatic control of the building management system (using communications protocols such as BACnet) to optimize energy efficiency whilst providing a comfortable climate for the building tenants.

Example developer tasks related to the platform might be to devise and implement a new alert to detect sub-optimal processes running within the building, to develop a new library to interact with an external API, or to optimize system performance via analysis and enhancement of the database and ORM layers.


Spectral develops technological solutions that unlock the value of energy storage, demand flexibility, and locally produced renewable energy, propelling the evolution of smart energy networks.Our website
