AI Controls Solutions Engineer (HVAC Systems)

About Phaidra

Phaidra is building the future of industrial automation.

The world today is filled with static, monolithic infrastructure. Factories, power plants, buildings, etc. operate the same they've operated for decades — because the controls programming is hard-coded. Thousands of lines of rules and heuristics that define how the machines interact with each other. The result of all this hard-coding is that facilities are frozen in time, unable to adapt to their environment while their performance slowly degrades.

Phaidra creates AI-powered control systems for the industrial sector, enabling industrial facilities to automatically learn and improve over time. Specifically:

We use reinforcement learning algorithms to provide this intelligence, converting raw sensor data into high-value actions and decisions. We focus on industrial applications, which tend to be well-sensorized with measurable KPIs — perfect for reinforcement learning. We enable domain experts (our users) to configure the AI control systems (i.e. agents) without writing code. They define what they want their AI agents to do, and we do it for them.

Our team has a track record of applying AI to some of the toughest problems. From achieving superhuman performance with DeepMind's AlphaGo , to reducing the energy required to cool Google's Data Centers by 40%, we deeply understand AI and how to apply it in production for massive impact.

Phaidra’s ability to achieve its mission is determined by our ability to work together — as defined by our core values: Agency, Velocity , Craft , and Truth . We seek individuals who embody these values, as they are instrumental in ensuring our team consistently delivers excellence and fosters an engaging and supportive culture

Phaidra is based in the USA, but we are 100% remote with no physical office. We hire employees internationally with the help of our partner, OysterHR . Our team is currently located throughout the USA, Canada, UK, Sweden, Spain, Portugal, the Netherlands, Singapore, Australia, and India.

Who You Are

As an AI Controls Solutions Engineer, you'll play a critical role in operationalizing and scaling Phaidra's solutions for enterprise data center customers.

We are seeking a team member located in the following area: USA or Canada.

Responsibilities

You will work closely with the Technical Program Managers (TPMs) and Data Scientists (DSs), as the technical experts for Phaidra's customers. Your role is to use Phaidra's platform and tools to put AI into production.

This role can be broken down into four concrete areas of responsibility:

You will use Phaidra’s products and your knowledge of the customers' needs to create a model of the facility for ingestion by our product lineup. This will require working closely with our Data Science team. You’ll understand the facility and configure our products according the facility and customer requirements. Then, you will commission and tune our products and assist in analyzing and triaging these systems in the support phase. You will work with the product team to identify and define product requirements based upon each customer’s specification and needs. You will work closely with other AI Controls Solutions Engineers and the Product team to ensure our automated tools enable Phaidra to scale across thousands of customers. You will translate a combination of customer-stated and customer-implied needs into coherent needs documentation for use by the software development team. You will provide ongoing support of deployed products, including support issue resolution and monitoring of performance. ****You will lead the deployment and support of multiple Solutions, perhaps in parallel. This includes resolving onboarding or support tickets by coordinating with the appropriate stakeholders or providing direct solutions. You will analyze the performance and viability of your engineered solutions, as well as troubleshoot, triage, and analyze issues with control systems and equipment. You will possess deep knowledge of Phaidra’s pipelines to effectively identify and address issues and actively manage risk. You will act as an internal and customer-facing SME on a range of initiatives, including the delivery of platinum support to customers, providing technical advice to research projects, and supporting sales and marketing efforts.
