Type: Full time

Auxo is hiring a Full Stack Engineer for a product-driven SaaS company building data-heavy web applications at scale.

You’ll ship full stack features end-to-end using .NET, React, and PostgreSQL, working in a product environment that values ownership, performance, and iteration. This role is for someone who enjoys ambiguity, thinks about observability and scalability early, and uses AI-assisted development tools daily in a structured and responsible way.

This is not a ticket-only role. You’ll help shape product decisions, improve performance as data grows, and ship features that matter.

• Own fullstack features from API to UI to database
• Build and maintain production APIs in C# and .NET
• Develop modern React interfaces using hooks and component-driven architecture
• Design and optimize PostgreSQL schemas, queries, and indexing strategies
• Improve performance, reliability, and observability as usage scales
• Collaborate with Product and Design to shape solutions when specs are incomplete
• Contribute to CI/CD pipelines and deployment processes
• Instrument features with logging and metrics to validate production behavior
• Use AI development tools daily to accelerate refactors, testing, debugging, and exploration
• Ship iteratively and measure outcomes

Who You Are

• 3+ years of professional software development experience
• Strong hands-on experience with C# and modern .NET
• Experience building React applications in production
• Comfortable designing APIs and modeling data
• Solid understanding of PostgreSQL including indexing and query optimization fundamentals
• Experience working in SaaS or web-based product environments
• Comfortable operating in ambiguity and making technical tradeoffs
• Uses AI-assisted development tools daily with validation discipline
• Strong communicator who can explain tradeoffs and technical decisions clearly
