Staff Machine Learning Engineer

The Role

We aim to establish the Span panel as the center of home energy and the backbone of the renewable distributed grid. Analytics and ML are essential tools to develop features for the smart, green, energy-efficient home of the future. Span’s unique ability to monitor and control individual circuits opens up a new avenue for proactive whole-home management and equipment failure detection. As Staff ML Engineer, you will leverage your deep understanding of ML, modeling, and statistics to solve problems including anomaly detection, event prediction and context understanding with the goal to optimally manage whole-home energy consumption, deliver meaningful insights to the customer, and notify them about a potential failure of equipment or hazards in their home. You’ll spearhead the entire development process, from working with the product team to define scope, the the firmware team to assess what can be implemented, the cloud team on ML ops, and the data collection team for training data. That said, we are a startup - broad range of production software development skills, flexibility to wear many hats, and enthusiasm to learn will go a long way.

Responsibilities

Lead the development of ML algorithms from the ground up which includes:

• Gain knowledge in the relevant domain (e.g.appliance signatures, failure modes, load disaggregation)

• Feature engineering (including embedded implementation)

• Use your experience with different machine learning frameworks to identify suitable tools for integration in Span’s software platform

• Integrate developed algorithms in our production code base with robust test coverage

• Work with the firmware and software teams to design Span’s edge model deployment framework

• Proactively identify opportunities within Span that can benefit from data science analysis

• Use fleet data to monitor algorithms in the field

• Guide selection of hardware for next generation products and recommend ways to future-proof our designs

Note: We’re a startup, so while this list is broad, it’s still just a start; you’ll end up wearing many hats during your time at Span.
