Responsibilities

Core backend development

Build maintainable backend services and REST APIs using Python, Django and Django REST Framework, with clear versioning and API contracts.
Design PostgreSQL schemas, constraints, indexes and manage versioned migrations to support scalable, tenant-aware data models.
Own authentication, permission models and organisation-level access controls so customer data stays properly isolated.
Implement approval workflows and traceable audit records to keep actions verifiable and compliant.

Reliability, data integrity and background processing

Handle concurrency, idempotency and duplicate requests to keep business records consistent under load.
Design reliable background jobs with retries and monitoring, using Celery or comparable systems where appropriate.
Write automated tests covering permissions, workflow transitions and data integrity to prevent regressions.
Define validation and error handling so integrations and consumers get predictable responses.

Deployment, observability and collaboration

Set up Docker-based deployment, document configuration and maintain backup and recovery procedures for production systems.
Instrument monitoring and logging, run recovery tests and participate in on-call troubleshooting when needed.
Work directly with the product owner to clarify requirements, explain trade-offs and deliver incremental progress.
Document APIs, operational runbooks and integration details for other teams and future handovers.

Requirements

Solid PostgreSQL and relational database design experience, including SQL, transactions and query optimisation.

Self-starter mindset with strong attention to detail and focus on data integrity.
