Software Engineer, Constellation Modelling

Meridian is building a fundamentally new model for sovereign space infrastructure—delivering complete, owned Low Earth Orbit (LEO) satellite constellations that provide governments and commercial operators with full control, assured access, and sovereign communications capability at a fraction of the cost of developing these systems independently.

Backed by leading venture capital investors and engineering partners, we are rapidly scaling the design, production, and deployment of the satellites, ground systems, and network infrastructure that will power Meridian's next-generation constellations.

Joining Meridian means working at the forefront of one of the world's most ambitious space programs underway today - designing and building constellations that will put sovereign connectivity within reach of nations and operators worldwide. You'll be part of a close-knit, collaborative team that thrives in a fast-paced, innovative environment, where your work directly advances the design, development, and deployment of satellite constellations that governments and enterprises around the world will depend on for secure, resilient, and sovereign connectivity.

Your Mission on the Team:

In this role you will be responsible for developing software tools that accelerate, streamline and organize engineering development within the organization. This includes:

• Creating infrastructure for high volume automated testing, data collection, analysis and reporting.
• Creating pipelines to organize and evaluate engineering trade studies through config management, version control, automated analysis workflows, visualization tools and comparison tools.
• Supporting infrastructure development for satellite technology demonstrations.

Basic Qualifications

• B.S. in computer science, software engineering, or a related technical field
• Strong proficiency in modern Python: type hints, testing, packaging, idiomatic library design
• Comfort with structured data formats and validation (YAML, JSON, pydantic or equivalent)
• Proficiency with Git workflows and CI/CD pipelines
• Experience writing and maintaining unit and integration tests
• Proficiency on Linux and the command line
• Demonstrated ability to build tools that other engineers actually adopt
• Ability to work autonomously and exercise good engineering judgement
• Strong interpersonal, verbal communication, and written communication skills

Preferred Qualifications

• 3+ years of professional software development experience
• Experience building data pipelines around automated test — capturing results, organizing them, making them queryable
• Hands-on experience automating lab test equipment
• Proficiency with instrument control: SCPI, VISA, PyVISA, IVI, GPIB, LXI
• Experience with the scientific Python stack: NumPy, SciPy, pandas
• Experience with visualization: matplotlib, Plotly, or web-based dashboards (Streamlit, Dash, Panel)
• Workflow orchestration (Airflow, Prefect, Dagster, or similar)
• Time-series or experiment-tracking systems (InfluxDB, TimescaleDB, MLflow, or similar)
• Containerization (Docker) and reproducible environments
• Prior experience in fast-moving startup engineering environments
