WFH Senior Full Stack Software Developer

The RoleWe are looking for an experienced full stack developer to work across the whole application — frontend, backend, data model and cloud infrastructure. This is a hands-on senior role in a small, distributed team: you will own features end to end rather than pick up work from one side of a boundary. We are progressively adopting Rust for backend services and want someone who is genuinely interested in being part of that.

Schedule

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

Tech StackArea and Technologies
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

What you will be doing

• 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.
• Reviewing code and setting engineering standards across an in-house team and an external development partner.
• 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).
• Infrastructure as code (Terraform, OpenTofu or CDK) and CI/CD pipelines.
• 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.
• Multi-tenant SaaS architecture, including tenant isolation and provisioning.
• Integrating with legacy or poorly documented third-party APIs.
• 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.
