Build Modern, Mission-Critical Systems with Room to Grow

Toyon is seeking an intermediate-level Software Engineer to help design and deliver modern, server-based applications supporting high-impact initiatives. This is not a legacy maintenance role — you’ll be working on actively evolving systems with a clear modernization roadmap, including a future strategic move towards more Kotlin-based development.

You’ll collaborate directly with a small, highly skilled engineering team and client stakeholders, contributing across the full software development lifecycle — from requirements and architecture through deployment and client demonstrations. Because our team is intentionally lean, your contributions will have visible impact, and you’ll have the opportunity to expand your technical footprint beyond backend development over time.

This is an ideal role for a Java developer who wants more ownership, broader exposure, and a pathway into emerging technologies.

What Makes This Role Different

• Modernization Focus: Work on actively evolving systems with a roadmap toward future Kotlin adoption
• Growth Beyond Backend: Opportunities to expand into front-end development (React), relational database design, and system architecture
• High Visibility: Small team environment where your work directly influences product direction
• Full Lifecycle Ownership: Participate in design, implementation, deployment, demos, and client engagement
• Mission-Driven Impact: Support clients with solutions that matter

What You’ll Do

• Collaborate with engineering team members and client stakeholders to gather and refine requirements
• Design and develop scalable, maintainable server-side applications using Java (17+) with an evolving Kotlin roadmap
• Contribute to architectural discussions, mockups, prototypes, and system enhancements
• Implement features and improvements using modern development practices
• Perform testing, debugging, and deployment to production environments
• Support client-facing demonstrations, presentations, and training sessions
• Participate in both office-based and on-site implementation efforts
