Principal Technical Architect, Prequip Space

Position Summary

The Principal Technical Architect, Prequip Space is responsible for owning and evolving the end-to-end technical architecture of the Space deployment of Prequip, spanning software systems, infrastructure, and machine learning capabilities. This role serves as the technical authority for ensuring the platform can be deployed, operated, and sustained in mission-critical environments with strict security, reliability, and operational constraints.

This role focuses on designing and operating systems that must function continuously in constrained, regulated, and often air-gapped environments with little to no connectivity exists, where uptime, observability, and explainability are essential. The Principal Technical Architect ensures that Prequip Space meets real world ops-floor requirements, including low latency, fault tolerance, secure deployment, and maintainability, while remaining aligned with the broader Prequip platform and its evolution across other domains such as Energy.

As a senior member of RS21's technical staff, this role blends strategic technical leadership with hands-on engineering. The Principal Technical Architect works closely with software engineers, platform teams, data scientists, and operational stakeholders to guide architectural decisions, contribute directly to production code, and ensure that machine learning systems behave predictably and transparently in live operational settings. This role plays a critical part in balancing innovation with operational discipline, ensuring that technical decisions support both immediate mission needs and long-term platform scalability.

This role is expected to contribute directly to production code and infrastructure implementation, not solely architectural oversight.

RS21's Prequip-Space platform, originally developed under AFRL's Hyperspace Challenge, delivers real-time anomaly detection for satellite telemetry. We are expanding this capability into operational mission environments and seeking leaders who can deploy and sustain it under real-world constraints.

Key Responsibilities

Technical Architecture & Platform Ownership

• Define and own the end-to-end technical architecture for Prequip Space deployments, ensuring alignment across software services, infrastructure, and machine learning systems.
• Establish architectural standards and technical guardrails that support reliability, security, and long-term maintainability in mission-critical environments.
• Evaluate and evolve existing system designs as Prequip Space scales and matures, balancing near term operational needs with long-term platform strategy.
• Ensure architectural alignment between Prequip Space and the broader Prequip platform, enabling shared capabilities while respecting domain specific constraints.

Infrastructure & Deployment Engineering

• Design and deploy infrastructure across constrained and regulated environments, including on-prem, sandboxed, and limited or no-internet deployments.
• Lead Kubernetes-based application hosting, deployment, and operational strategies, including cluster configuration, upgrades, and lifecycle management.
• Ensure infrastructure designs meet ops-floor expectations for availability, fault tolerance, performance, and security.
• Partner with security and platform teams to support accreditation, hardening, and compliance requirements.
• Promote infrastructure-as-code, automation, and repeatable deployment patterns where feasible.

Machine Learning & MLOps Systems

• Own and evolve the shared ML and MLOps pipeline used across Prequip for Space and Prequip for Energy.
• Oversee the design, deployment, and ongoing operation of anomaly detection and event prediction models that analyze time-series telemetry.
• Ensure ML systems are explainable, observable, and appropriate for real-time operational decision-making.
• Collaborate with data science teams to understand model behavior, data quality issues, and performance degradation in live environments.
• Support model lifecycle management, including versioning, retraining, and validation in constrained deployments.

Software Engineering & Hands-On Development

• Contribute directly to production code across APIs, data pipelines, deployment tooling, and ML integration layers.
• Ensure code quality, testability, and maintainability across shared and space-specific components.
• Provide technical guidance and mentorship to engineers working across the Prequip code base.
• Review and influence design and implementation decisions to ensure consistency with architectural standards.

Observability, Reliability & Operations

• Design and implement observability strategies that enable real-time monitoring, debugging, and performance analysis in ops-floor environments.
• Ensure systems support effective incident response, root cause analysis, and continuous improvement.
• Partner with operations stakeholders to align system behavior with real-world workflows and expectations.
• Drive improvements in system reliability, resilience, and operational readiness through proactive…
