Navigation Engineer (Ground Software) Verified today

About Logos Space

Logos Space is building a proliferated Low Earth Orbit constellation to deliver resilient, high-performance connectivity to enterprise and government users. The Navigation team designs and builds software and infrastructure for spacecraft timing, astrodynamics, maneuver planning, orbit determination, and related workflows across flight and ground systems.

The Role

You will develop the Ground Navigation Software (GNS) stack used to generate, screen, replan, validate, approve, release, and track navigation products for the constellation. This operational software stitches together orbit determination, orbit propagation, event prediction, maneuver planning, conjunction screening, replanning, validation, product repositories, configuration management, and operational data flows into repeatable per-spacecraft workflows.

You will build the software backbone that turns navigation algorithms, reference data, spacecraft telemetry, external data products, and operational procedures into production-grade ground infrastructure. The work spans backend services, workflow orchestration, databases, product repositories, run-state management, provenance tracking, validation gates, operator tooling, APIs, automated retries, observability, CI/CD, and deployment.

Responsibilities

• Develop and maintain backend and infrastructure software for the GNS stack
• Design and implement the GNS control plane to schedule, execute, monitor, retry, cancel, and close navigation product runs
• Build workflow orchestration and product release workflows
• Design databases, schemas, APIs, and data services for run state, product metadata, spacecraft configuration, operational constraints, provenance, approvals, and audit history
• Develop the navigation reference data and configuration store for mission configurations, Earth orientation data, space weather, planetary ephemerides, spacecraft models, maneuver assumptions, and external data products
• Build the navigation product repository for candidate products, released products, versions, lineage, run artifacts, validation results, and downstream delivery status
• Implement product quality checks, operational approval criteria, completeness checks, consistency checks, freshness checks, and release-readiness rules
• Develop APIs and service interfaces for mission operations, ground software, flight software, constellation planning, and analysis tools to consume navigation products
• Implement operator-facing tools for run monitoring, product review, validation status, data freshness, failure triage, release tracking, and system health
• Build ingestion pipelines for spacecraft telemetry, reference data, operational constraints, and external data products
• Implement data validation, schema validation, version control, provenance tracking, reproducibility, and configuration-controlled rerun capability
• Develop logging, metrics, alerting, traceability, and observability infrastructure for navigation workflows
• Build Docker-based local development, integration-test, and CI/CD environments for multi-service navigation ground software
• Develop automated test infrastructure including unit tests, integration tests, end-to-end workflow tests, regression tests, replay tests, and release-readiness checks
• Support integration with cloud or on-premise infrastructure, containerized services, message buses, object stores, relational databases, and operational deployment environments
• Support integrated test campaigns, operational rehearsals, commissioning, flight-data investigations, anomaly response, and continuous improvement

Basic Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Aerospace Engineering, Applied Mathematics, Physics, or related STEM field, or equivalent practical experience
• 5+ years of relevant professional experience building ground software, backend services, operational software, workflow orchestration systems, event-driven architectures, data platforms, mission operations software, or high-reliability engineering software
• Proficiency in Python, modern C++, or another production backend software language
• Experience working with structured data products, metadata, configuration data, time-series data, telemetry, logs, or engineering artifacts
• Experience with production containerized development and deployment workflows using Docker, Kubernetes, or equivalent tools
• Experience building, testing, and debugging microservice software systems in local, CI/CD, and integration-test environments
• Experience with Linux-based development environments, Git, automated testing, CI/CD, and modern software delivery workflows
• Working knowledge of distributed systems fundamentals including service interfaces, failure handling, retries, idempotency, observability, and data consistency
• Ability to work across software, operations, and domain engineering teams to turn operational concepts into reliable production workflows
• Experience with production service observability including metrics, logs, traces, alerting, dashboards, health checks, and operational runbooks
• Experience building operator-facing dashboards, review tools, internal web applications, or operational displays
• Strong written and verbal communication skills

Preferred Qualifications

• 8+ years of relevant experience and ability to independently own technical workstreams
• Experience building spacecraft ground software systems, mission operations software, flight dynamics systems, constellation operations tools, or operational aerospace software
• Experience with navigation, flight dynamics, orbit determination, orbit propagation, maneuver planning, conjunction screening, mission planning, or spacecraft operations workflows
• Experience designing product repositories, provenance systems, approval workflows, release gates, configuration management systems, or audit-controlled operational software
• Experience with deterministic replay, run reconstruction, data lineage, reproducible pipelines, regression infrastructure, or automated validation of operational products
• Experience integrating software with external data providers, telemetry systems, mission planning systems, command and telemetry systems, or ground-to-flight interfaces
• Familiarity with CCSDS data formats, spacecraft command and telemetry systems, time systems, ephemeris products, maneuver products, or operational navigation data formats
