ML lifecycle: MLflow.

Your challenge

Delivery & serving services

Co-own and extend the delivery-management service (SDMS) and the insight-generation and post-processing services, the path that turns model detections into delivered, customer-ready insights.

Harden these into well-tested, documented services so they are no longer a single-person dependency.

Platform, orchestration & AWS

Own and maintain the AWS and Prefect delivery platform, meaning the Lambda-based glue, the orchestration flows and the cross-repo release, and keep it deterministic and repeatable.

Manage the PostgreSQL and PostGIS data model behind delivery, including the schema and the migrations via Alembic.

Reliability & delivery operations

Be a reliable second owner for where the pipeline breaks. You unblock stuck orchestration runs, keep delivery SLAs met, and cut out manual steps.

Data quality, metadata & diagnostics

Automate QA across the serving path, covering schema and geometry integrity and coverage gaps, and maintain structured metadata and STAC entries so every delivery is traceable.

Your profile

Strong Python in production, not scripting-only.

Building and running backend services with FastAPI (or similar), SQLAlchemy, Alembic and Pydantic.

PostgreSQL, and spatial data (PostGIS, GeoAlchemy2 or equivalent) is a strong plus.

AWS in production, mainly S3, Lambda, EC2 and IAM basics.

Orchestration with Prefect, Airflow, Dagster or equivalent.

Comfort handling geospatial raster and vector data (rasterio, geopandas, shapely, STAC, COG) at a level where you can move it reliably.

Pragmatic delivery and a reliability and ops mindset, so you ship robust, well-tested services and keep them running.

Ownership and verification mindset, so you validate outputs against reality and catch results that look right but are not, using judgment and not just code.

Distributed compute with Ray or Anyscale is a plus.

MLflow, or experiment and dataset versioning is a plus.

Remote-sensing or geospatial foundations, or SAR exposure (Capella, Sentinel-1) is a plus.

Observability with structured logging, OpenTelemetry and alerting is a plus.

Satellite provider APIs such as Capella, UP42, Planet and ICEYE is a plus.
