Software Engineer - RFGL Systems

Job Overview

Spire Global is a space-to-cloud analytics company that owns and operates the largest multi-purpose constellation of satellites. We are hiring a Software Engineer to join our US-focused RFGL (Radio Frequency Geolocation) and Signals Intelligence (SIGINT) product team.

Location:

Washington, District of Columbia, United States

Department:
Engineering

This role is not the algorithmic or scientific core of our geolocation capability; instead you will own the operational side: deploying and maintaining production RFGL/SIGINT software systems on AWS, handling data pipelines and integrations (internal + customer-facing), building monitoring tooling and automation, supporting satellite tasking workflows, and troubleshooting/fixing issues across payloads, ground systems, and infrastructure.

ITAR restrictions apply. You will work under direct supervision of a senior software engineer on a small, high‑impact team. This is an early‑to‑mid‑career hands‑on role for someone who thrives in iterative, production‑focused environments.

• 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

• 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, Cloud Watch, 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

• 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, Cloud Formation, etc.)
• Prior exposure to space, aerospace, satellite operations, ground stations, or related domains
• Familiarity with containerization (Docker, Kubernetes), CI/CD pipelines (Git Hub Actions, etc.), or observability tools (Prometheus, Grafana, ELK stack)
• Any experience reading/debugging C++ or embedded systems code (helpful for payload/ground system work)

Hybrid work model: minimum three days per week in the office.

Access to US export‑controlled software and/or technology may be required.

Base Salary Range: $90,000 – $130,500 USD.

Eligible for commissions and annual equity awards. Includes vacation, sick, personal time off; optional medical, dental, vision, life, and disability coverage; a 401(K) plan; health and wellness reimbursement; participation in Employee Stock Purchase Plan.

• Employee Assistance Program (EAP)
• Employee Stock Purchase Program (ESPP)
• Family Leave
• Fitness Reimbursement
• Employee Referral Program
