Working primarily with Python, Django, PostgreSQL, and REST APIs, you will investigate complex technical issues, develop tailored solutions, and improve the tools and processes that support customer onboarding. You will also guide backend engineers while collaborating directly with customers to understand requirements and resolve challenges efficiently. In this remote, international environment, you will have significant technical ownership and the opportunity to influence engineering practices, automation, and operational reliability. This role is ideal for an experienced engineer who combines strong coding expertise with leadership, analytical thinking, and a commitment to customer success.

Lead customer data migration projects from initial investigation and planning through data transformation, validation, implementation, and successful completion.

Analyze, extract, transform, and migrate data from diverse customer systems, database models, file formats, and external data sources.

Develop, maintain, and optimize Python and Django scripts, utilities, and internal tools to support migration workflows and improve operational efficiency.

Work extensively with PostgreSQL, relational databases, and NoSQL systems to manage complex queries, data structures, schema changes, and database migrations.

Investigate customer-reported technical issues, troubleshoot unfamiliar code and system behavior, identify root causes, and implement reliable solutions.

Manage customer-specific backend modifications, bug fixes, integrations, and production data issues, ensuring that technical problems are resolved thoroughly.

Design, implement, and troubleshoot REST API integrations and connections with third-party systems to support customer migrations and ongoing technical requirements.

Communicate directly with customers to clarify technical requirements, investigate reported issues, explain solutions, and coordinate implementation activities.

Provide technical leadership and guidance to backend engineers, supporting sound engineering decisions, effective collaboration, and high-quality delivery.

Collaborate with cross-functional teams to coordinate technical priorities, resolve dependencies, and ensure successful customer outcomes.

Continuously improve migration processes, automation, documentation, and internal tooling to make onboarding more consistent, reliable, and scalable.

Apply AI-powered development tools to improve coding productivity, debugging, and engineering workflows while maintaining high standards of code quality and reliability.
