Own the Scan domain technical direction: connector architecture, ingestion reliability, scalability, and maintainability.
Contribute directly with hands-on development (you will code regularly).
Lead design reviews and establish shared practices (quality, testing, observability, maintainability).
Turn product needs into clear technical plans, align stakeholders, and deliver iteratively.
Build and maintain connectors integrating with third-party REST APIs and platforms (OAuth2/API keys, pagination, rate limits, retries, webhooks when relevant).
Design reliable ingestion flows: incremental sync, idempotency, backfills, error recovery, reconciliation, and safe schema evolution.
Maintain our desktop application written in Kotlin used for connector development/operations (configuration, debugging, validation workflows, diagnostics).
Apply and promote testing practices (unit/integration; contract tests where relevant).
Improve observability (logs/metrics/traces), monitor connector health, and lead investigations for production issues.
Support the team’s growth through mentoring, pairing/mob sessions, and constructive feedback.
Lead PR reviews and help the team make sound trade-offs.
Coordinate with other squads when changes touch .NET services or Angular UI.

Hands-on experience with Maven in production projects (multi-modules, dependency management, build/release pipelines).
Experience integrating external REST APIs and third-party platforms with real-world constraints.
Good foundations in system design for reliability: resilience patterns, idempotency, consistency, performance, and operability.
Solid understanding of SQL and relational databases (schema design, indexing, migrations, performance).
Comfortable with Git workflows and collaborative code reviews.
Experience applying testing practices and writing maintainable, testable code.
Comfortable working with cloud/production constraints (deployments, monitoring, incident/debug workflow).
