WFH Senior Full Stack Software Developer

The Role We 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 Stack Area 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.
