Responsibilities

• Deploy, maintain, and monitor RFGL and SIGINT software products in AWS production environments, ensuring high availability and performance for real customers
• Build and improve data handling pipelines, integrations with Spire internal systems, and customer-facing data delivery platforms
• Develop tooling and automation for production monitoring, alerting, logging, and operational observability
• Support satellite tasking operations and command workflows that enable RF geolocation missions
• Investigate and resolve bugs, performance issues, or enhancement needs in satellite payload software, ground systems, and related infrastructure
• Collaborate closely with the senior software engineer, RF domain experts, and cross-functional teams to implement incremental improvements that directly enhance RFGL product reliability and capability
• Contribute to infrastructure automation, CI/CD processes, and secure deployment practices in a regulated environment

Requirements

• 2–5 years of professional software engineering experience (or equivalent academic + internship/project work for strong early-career candidates)
• Demonstrated hands-on experience with AWS (EC2, S3, Lambda, ECS/EKS, CloudWatch, IAM, or similar services) — this is critical
• Proficiency in Python for scripting, automation, data processing, and backend tooling
• Solid Linux fundamentals (administration, bash scripting, system troubleshooting)
• Experience building or maintaining production systems with a focus on reliability, monitoring, and operational excellence
• Strong communication skills and comfort working collaboratively in a small team under senior guidance

Preferred Qualifications

• Security background or experience implementing secure engineering practices, compliance controls, or working in regulated/government environments
• Background with big data systems, pipelines, or tools (e.g., Spark, Kafka, Databricks, S3-based data lakes)
• Infrastructure-as-Code experience (Terraform, Ansible, CloudFormation, etc.)
• Prior exposure to space, aerospace, satellite operations, ground stations, or related domains
• Familiarity with containerization (Docker, Kubernetes), CI/CD pipelines (GitHub Actions, etc.), or observability tools (Prometheus, Grafana, ELK stack)
• Any experience reading/debugging C++ or embedded systems code (helpful for payload/ground system work)
