Nice To Haves

• A strong understanding of cloud computing, APIs, and software architecture is highly desirable.
• Focus on writing high-performance, asynchronous code that adheres to the program's architectural patterns.
• Ensure UI elements are reusable and integrated correctly with the backend.
• Ensure 100% traceability between tests and mission requirements.
• Lead the integration of CesiumJS and STK into the React frontend.
• Optimize the rendering of 4D space-track data to ensure low latency and high frame rates.
• Leverage Rancher for service scaling and environment configuration management.
• Ensure the ExpressJS gateway layer efficiently handles telemetry streams and user authentication.
• Harden GitLab CI/CD pipelines by integrating automated security tools (SAST/DAST) and container image signing.
• Implement high-availability data patterns, including index management in OpenSearch and data sharding strategies for large geospatial datasets.
• Conduct peer code reviews focused on security, performance, and adherence to the Lead Engineer’s architectural vision.
• You will make the final determination on frameworks (e.g., Quarkus vs. Spring Boot) and architectural patterns that ensure long-term scalability, performance, and low technical debt.
• You are responsible for translating orbital mechanics, mission planning logic, and satellite C2 requirements into high-performance software architecture.
• This includes automating security compliance reporting, dependency management in restricted networks, and streamlined deployment to production.
• Focus on low-latency data distribution and high-availability patterns.
• You are responsible for the security posture of everything from base Docker images and Kubernetes network policies to React frontend hardening.
• Define the strategy for service mesh (e.g., Istio or Linkerd), automated scaling, and cluster resource management within Rancher to handle fluctuating mission workloads.
• You are responsible for setting the "build-it-right-first" technical culture, ensuring senior and mid-level devs adhere to established patterns.

Responsibilities

• Feature Development: Build and maintain new Java microservices using Quarkus or Spring Boot. Focus on writing high-performance, asynchronous code that adheres to the program's architectural patterns.
• Component-Based UI: Develop modular React components using Vite and the Astro UXDS design system. Ensure UI elements are reusable and integrated correctly with the backend.
• BFF Integration: Implement and extend ExpressJS middleware to handle specific frontend-to-backend data transformations and API routing.
• Local Containerization: Use Docker to build and test containerized services locally, ensuring parity with the development and test Kubernetes environments.
• Automated Testing: Own the unit and integration testing lifecycle using JUnit and modern frontend testing frameworks. Ensure 100% traceability between tests and mission requirements.
• Pipeline Contribution: Maintain and update GitLab CI/CD job definitions for specific services, including build scripts, linting, and automated vulnerability scanning.
• Module Design: Take ownership of specific functional modules, defining the internal architecture of services and how they interact with the broader Quarkus/Spring Boot ecosystem.
• Geospatial Visualization Engine: Lead the integration of CesiumJS and STK into the React frontend. Optimize the rendering of 4D space-track data to ensure low latency and high frame rates.
• Microservices Orchestration: Manage and optimize Kubernetes manifests and Helm charts. Leverage Rancher for service scaling and environment configuration management.
• API Governance: Design and document stable API contracts for microservices. Ensure the ExpressJS gateway layer efficiently handles telemetry streams and user authentication.
• DevSecOps Integration: Harden GitLab CI/CD pipelines by integrating automated security tools (SAST/DAST) and container image signing.
• Data Strategy Execution: Implement high-availability data patterns, including index management in OpenSearch and data sharding strategies for large geospatial datasets.
• Technical Review: Conduct peer code reviews focused on security, performance, and adherence to the Lead Engineer’s architectural vision.
• Core Stack Architecture: Establish the foundational technical stack for a multi-year program. You will make the final determination on frameworks (e.g., Quarkus vs. Spring Boot) and architectural patterns that ensure long-term scalability, performance, and low technical debt.
• Space Domain Technical Leadership: Bridge the gap between systems engineering and software. You are responsible for translating orbital mechanics, mission planning logic, and satellite C2 requirements into high-performance software architecture.
• CI/CD & Deployment Strategy: Architect the end-to-end GitLab CI/CD strategy specifically for cleared and air-gapped environments. This includes automating security compliance reporting, dependency management in restricted networks, and streamlined deployment to production.
• Distributed System Design: Engineer a resilient "system-of-systems" capable of processing real-time telemetry and 4D geospatial visualizations (CesiumJS/STK). Focus on low-latency data distribution and high-availability patterns.
• Zero Trust & Security Hardening: Implement a Zero Trust security model across the full stack. You are responsible for the security posture of everything from base Docker images and Kubernetes network policies to React frontend hardening.
• Kubernetes Orchestration & Service Mesh: Define the strategy for service mesh (e.g., Istio or Linkerd), automated scaling, and cluster resource management within Rancher to handle fluctuating mission workloads.
• Technical Mentorship & Culture: Direct the engineering team through deep-dive code and architectural reviews. You are responsible for setting the "build-it-right-first" technical culture, ensuring senior and mid-level devs adhere to established patterns.
