Senior Software Engineer (Data Platform)

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:  Transparency ,  Collaboration ,  Operational Excellence ,  Ownership , and  Empathy. 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

We're looking for an experienced Software Engineer to anchor the technical direction of our growing Data Platform team. You'll drive architecture decisions for distributed, multi-tenant systems and raise the bar for the engineers around you. You are bold, creative, and have deep empathy for customers.

• Strong experience designing and implementing distributed systems for data ingestion, storage, and processing.


• Proven expertise building, operating, and monitoring large-scale multi-tenant systems while accounting for high availability, fault tolerance, and performance.


• Ability to take ownership of realtime production systems - aligning technical with business requirements, raising the bar for operational excellence and on-call incident handling


• Ability to collaborate and communicate effectively in an all-remote setting.


• Approach your work with curiosity, ownership, transparency, directness, outcome orientation, and customer empathy.


• Experience with latest batch & realtime data processing, storage & service technologies such as Apache Flink.

Preferred Experience

• Hands-on experience designing environment-agnostic abstractions that let applications run across cloud, hybrid, and on-prem deployments, with working knowledge of containerization and orchestration tools like Docker and Kubernetes.


• Experience with self-service data platforms, data lakes, or lakehouses at scale.

Our Stack

• Python, Go
