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

Qualifications & Experience

At least 3 years of professional software development experience, including production backend applications.
Proven experience owning backend features from design through deployment and live support.
Comfort working independently with a product owner and explaining technical choices in clear English to non-technical stakeholders.
Track record of clarifying requirements, demonstrating progress and raising risks early in the project lifecycle.

Hard Skills & Knowledge

Strong Python and Django skills with practical experience building REST APIs; Django REST Framework is preferred.
Solid PostgreSQL and relational database design experience, including SQL, transactions and query optimisation.
Experience implementing authentication, permissions and organisation- or customer-level access restrictions, plus understanding of concurrency control and idempotency patterns.
Practical experience with automated testing, Git, Docker, Linux and production troubleshooting. Familiarity with Celery, Redis, scheduled tasks, AWS, private object storage, CI/CD, monitoring, row-level security, audit logging and OpenAPI is a plus.

Soft Skills & Qualities

Clear communicator who can translate technical trade-offs for a non-technical product owner.
Self-starter mindset with strong attention to detail and focus on data integrity.
Practical problem-solver who documents decisions and supports recovery testing and incident response.
Collaborative team member willing to produce clear API documentation and operational handover materials.
