We’re looking for a Senior Software Engineer to join our Earth Observation (EO) Ground Processing and Weather Infrastructure team. This role is critical to the reliable and scalable processing of satellite data from our constellation. You’ll begin by working on EO-focused pipelines and backend systems, and grow into a broader role supporting cloud infrastructure and AWS operations across all EO and weather data products.

Key Responsibilities

• EO Data Processing: Build and maintain scalable pipelines for ingesting and processing satellite Earth Observation data;
• Cloud Infrastructure: Design and manage cloud-native systems in AWS to ensure high availability, fault tolerance, and performance for EO and weather services;
• Backend Development: Develop backend services and APIs in Python and/or Golang to support internal tools and external customer products;
• Infrastructure as Code: Use Terraform (or equivalent) to manage and evolve infrastructure for EO and weather pipelines;
• Monitoring & Reliability: Implement observability tools (Grafana, Sentry, CloudWatch, etc.) and CI/CD workflows to ensure system robustness and fast recovery from failures;
• Cross-Team Collaboration: Work closely with satellite operations, science, and product teams to deliver performant, customer-focused solutions;
• Production Operations: Support and optimize mission-critical, operational EO and weather services in real-time environments;
• Security & Best Practices: Apply modern security and deployment best practices throughout the software development lifecycle.

Required Qualifications

• 5+ years of experience in backend or systems-level software engineering;
• Proficient in Python (required); Golang is a plus;
• Strong experience with AWS services (e.g., S3, Lambda, EC2, DynamoDB);
• Experience designing and operating event-driven and schedule-based data pipelines;
• Familiarity with geospatial formats like netCDF, GRIB, GeoTIFF, and common weather model data structures;
• Experience with Linux, Docker, and CI/CD tools;
• Strong understanding of distributed systems, API development, and operational monitoring;
• Solid debugging and troubleshooting skills in production environments;
• Strong communication and collaboration skills.

Preferred Qualifications

• Familiarity with EO and satellite ground processing systems;
• Experience with PostgreSQL and/or NoSQL (e.g., DynamoDB);
• Exposure to the Pangeo ecosystem (e.g., Xarray, Dask, Zarr);
• Experience with Kubernetes and container orchestration;
• Networking or security background is a plus;
• Passion for working at the intersection of space, weather, and real-time data systems.
