The Role We are looking for an experienced Senior Full Stack Software Developer to work across the whole application — frontend, backend, data model and cloud infrastructure. We are progressively adopting Rust for backend services and want someone who is genuinely interested in being part of that.

40 hours per week, flexible during client business hours (Sydney, AU)

Frontend - React 18, TypeScript, Vite, TanStack Query, React Router, Recharts, Vitest, Storybook
Backend - Python 3.14, FastAPI, SQLAlchemy, Alembic, Pydantic, Pytest
Database - PostgreSQL / Amazon Aurora, multi-tenant architecture
Cloud - AWS — Lambda, API Gateway, EventBridge, S3, CloudFront, Secrets Manager, IAM
Infrastructure - OpenTofu / Terraform, Docker, GitLab CI/CD
Authentication - Auth0, AWS Cognito
Emerging - Rust (axum, tokio) for new and migrated backend services

Building features end to end — data model, API, user interface and tests — across both web portals and the backend.
Designing and evolving a multi-tenant PostgreSQL data model as the product grows into new customer types and new industries. Building and maintaining integrations with customers' third-party booking and inventory systems, which are frequently legacy and inconsistently documented.
Developing the automated pricing pipeline: scheduled serverless workers that assemble each day's pricing run, call our pricing engine's API, apply commercial rules and approval policy, and publish the results.
Owning cloud infrastructure and deployment pipelines alongside the rest of the team.
Contributing to the gradual adoption of Rust in the backend.

Essential Experience
Substantial commercial experience as a full stack developer, including genuine production ownership of a system rather than only feature-level delivery.
Strong Python — modern, type-annotated code with a web framework such as FastAPI, Django or Flask.
Strong React, written in TypeScript.
Solid relational database skills in PostgreSQL or equivalent: schema design, migrations, and query performance.
Hands-on AWS experience, ideally serverless (Lambda, API Gateway).
Automated testing as a normal part of delivery, not an afterthought.
Clear written communication, and comfort working in a distributed team where technical decisions are documented and debated in writing.
Desirable Rust in production, particularly asynchronous web services.
Dynamic pricing, revenue management, yield management or e-commerce pricing experience.
Data visualization and charting over real-world, incomplete datasets.
Auth0, AWS Cognito, OAuth 2.0 and OIDC.
Experience mentoring or leading offshore or partner development teams.
