Tech Lead – Engineering Manager, Connectivity & Ingestion

Role Overview

• 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.
• Normalize and map external data models into DataGalaxy’s internal model with good data quality and consistency.
• Maintain our desktop application written in Kotlin used for connector development/operations (configuration, debugging, validation workflows, diagnostics).
• Improve developer and operator experience: packaging, configuration, troubleshooting, and usability.
• 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.
• Manage technical debt: refactoring, dependency upgrades, CI/CD improvements.
• 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.

Requirements

• Proven experience building backend services with Kotlin.
• 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).
• Proficiency in English.
• Familiarity with the data domain (warehouses/lakes, catalogs, orchestration) and governance concepts.
• Experience integrating data platforms such as Databricks (and/or similar ecosystems: Snowflake, BigQuery, Redshift, etc.).
• Understanding of metadata, lineage, schemas, and common enterprise data integration patterns.
• Comfortable working with AI-assisted development tools (e.g. coding agents, copilots) as part of your daily workflow, and open to evolving your practices as these tools mature.
• Experience building desktop applications in Kotlin (JavaFX / Compose for Desktop / Swing).
• Experience with .NET (C#) services in a heterogeneous stack.
• Angular knowledge (or frontend fundamentals) to support connector configuration/visibility in the product UI.
• Experience with Kubernetes (especially EKS) and observability tooling.
• Experience with event-driven ingestion patterns and/or queue-based processing.
