We are seeking an ML Annotation Tools Developer with experience building the infrastructure and interfaces required to manipulate large 2D and 3D media datasets. You will be responsible for the end-to-end tooling ecosystem that enables our annotation teams and external vendors to create high-quality ground truth data for our ML models.

Responsibilities

• Tooling Development: Lead the development of annotation interfaces, starting with Java and JOSM (Java OpenStreetMap Editor) customizations, and eventually expanding into bespoke Python-based tools and plugins.

• Geospatial Infrastructure: Build and host secure Map Servers to serve our proprietary data for annotation. You will ensure these servers are performant and integrated into our data pipeline.

• Spatial Database Management: Design and optimize PostGIS databases to store, query, and version complex geospatial metadata and annotation layers.

• Security & Vendor Collaboration: Work closely with the Cybersecurity team to ensure that data shared with external annotation vendors is hosted securely, using robust access controls and encrypted delivery methods.

• Cross-Functional Coordination: Collaborate with ML Engineers and TPMs to translate complex data requirements into intuitive UI/UX features that minimize human error during the annotation process.

• Process Automation: Develop scripts and workflows in Python to automate data ingestion, quality checks, and the export of annotated datasets into training-ready formats.

• Graduate degree in Computer Science, Software Engineering, Geomatics, or a related field.

• Industry Context: Prior experience in industries with complex multi-disciplinary teams such as robotics, smart grids, precision agriculture, game development, or aerospace.

• Technical Proficiency:

• Core Languages: Fluency in Java (for JOSM/Desktop tooling) and Python (for pipeline and web tooling).

• Database Expertise: Proven experience with PostGIS and PostgreSQL, including writing complex spatial queries and optimizing geographic indexes.

• Geospatial Expertise: Familiarity with JOSM, OpenStreetMap data structures, and Map Server technologies (e.g., GeoServer, MapServer, or TileServer GL).

• Environment: Fluency with Git and the Unix shell.

• Security Mindset: Understanding of secure data hosting, VPNs, and IAM (Identity and Access Management) for third-party vendor access.

Desired Characteristics

• High Attention to Detail: A "conscientious" approach to tool design to ensure data integrity at the source.

• Problem-Solving Mindset: Ability to bridge the gap between legacy GIS tools and modern ML data requirements.

• Collaborative Spirit: Comfortable working with external vendors and internal security teams to balance usability with safety.

Eligibility Requirements

• Must have unrestricted work authorization to work in the United States
