Senior Software Engineer (On-Premises Platform)

Phaidra builds AI-powered control systems for industrial facilities. The Senior Software Engineer will lead the design and implementation of infrastructure for deploying and operating Phaidra’s control software inside customer networks, including reusable platform capabilities for connectivity, deployment, and operations.

Responsibilities:

• Design and build a standardized Phaidra infrastructure footprint inside customer networks that gives product teams a consistent target for deploying control agents and supporting services
• Define the compute, operating-system, networking, storage, identity, configuration, and observability capabilities that every deployment can rely on
• Evaluate when Phaidra should supply or standardize hardware, and integrate that hardware into a repeatable deployment and support model
• Build the platform services and interfaces other teams use to package, deploy, configure, monitor, and safely update their software
• Provide resource isolation, health management, restart and recovery behavior, and version compatibility at the platform layer
• Partner with controls and product engineers to define clear contracts between the platform, deployed software, local equipment, and cloud services
• Build reliable data ingress, command egress, and connection-management capabilities between Phaidra software and customer control systems
• Develop or integrate clients and adapters for programmable logic controllers (PLCs), building management systems (BMS), supervisory control and data acquisition systems (SCADA), and protocols such as OPC UA and Modbus/TCP
• Work with customer IT and operations teams to satisfy site networking, security, access, and performance constraints
• Build repeatable installation, commissioning, configuration, upgrade, rollback, backup, and recovery workflows
• Provide remote management and diagnostics when permitted while ensuring the local platform remains safe and useful through restricted or intermittent connectivity
• Build telemetry, alerting, and support tooling that lets Phaidra understand platform and agent health across deployed sites
• Lead system design and implementation for customer-site infrastructure and deployment capabilities
• Work with RL Control to define requirements and interfaces, coordinating with other teams where needed
• Document technical decisions, identify broader infrastructure tradeoffs, and turn recurring needs into reusable platform capabilities

Requirements:

• You are a senior software engineer who has built and operated platform infrastructure inside customer-controlled networks, where the environment cannot be treated like another cloud account
• You are comfortable using software and automation to create consistent deployment environments across operating systems, networking, compute, storage, and observability
• You have deep empathy for customers and their IT and operations teams
• You can turn site-specific constraints into reusable platform capabilities without pretending that every facility is identical
• We are seeking teammates who are based in the United States or Canada (Eastern timezone)
• 5+ years of professional experience in software engineering, platform engineering, infrastructure engineering, SRE, or a related area
• Experience building or operating infrastructure in customer-controlled, on-premises, hybrid, or otherwise restricted network environments
• Strong programming skills in a high-level language such as Python, Go, or C# and experience building maintainable automation or platform services
• Working knowledge of Linux, containers, networking, and production debugging
• Experience building repeatable automation for provisioning, configuration, deployment, updates, or operational management
• Ability to turn varied deployment requirements into reusable platform capabilities and supported operational patterns
• Demonstrated ability to lead the design and implementation of ambiguous technical work and collaborate effectively across teams
• Docker and Kubernetes in on-premises, hybrid, or resource-constrained environments
• Familiarity with deploying and supporting physical devices, gateways, or industrial-compute systems in customer networks
• Experience with or working knowledge of real-time operating systems (RTOS) and software that interacts with physical equipment
• OPC UA, Modbus/TCP, BACnet, MQTT, or other industrial and device protocols
• Cross-platform development for Linux and Windows
• Local message brokers, durable queues, and event-driven systems
• Private networking, certificate management, workload identity, and secrets distribution
• Observability for remote systems using Prometheus, Grafana, OpenTelemetry, or equivalent tools
• Phaidra only hires individuals who are legally authorized to work in the specified location(s) above
• Candidates requiring visa sponsorship, either now or in the future, are not eligible for hire
• Secure remote access for systems operating in customer environments
• Synchronization between local and cloud services, including operation through limited or interrupted connectivity
• Bare-metal provisioning, secure boot, trusted platform modules (TPMs), or hardware-backed identity
• GPU or other specialized compute in customer environments
• Experience commissioning software that monitors or controls physical equipment
• Familiarity with safety-sensitive control systems
