Senior Full Stack Java Developer Jobs in Olathe, KS

Organizational Profile  

Strong Family believes that every family has the inherent potential to thrive. Rather than treating the symptoms of crisis, we address the root causes of family breakdown and the orphan cycle through scalable, community-led solutions that restore dignity, strengthen caregivers, and promote long-term stability—particularly in developing-country contexts where families face systemic economic and social pressures. 

 
Our strengths-based, technology-enabled framework equips local churches and community leaders with training, tools, and evaluation systems to support families holistically. Through digital platforms, coursework, and data-informed insights, Strong Family helps communities identify needs, mobilize local assets, and track measurable progress as families move from  suffering to flourishing. 

 
Strong Family is currently implemented across East Africa, India, and Haiti, where hundreds of local churches have adopted the framework and demonstrated sustained family stability and child well-being. Building on this foundation, we are expanding into additional developing- country regions globally, scaling a proven model that empowers families, strengthens communities, and creates durable, locally owned change.

Our Impact  

The results have been more powerful than we ever imagined. Families not only find healing within themselves but also begin to change the trajectory of their communities. By empowering families to flourish in practical, relational, and spiritual ways, Strong Family is addressing a global crisis at its roots—creating pathways for children to remain where they belong: safe, loved, and within family. 

Position Summary  

We are seeking a Senior Full Stack Engineer to help build and evolve the technology that powers Strong Family’s global expansion. This role is ideal for an experienced engineer who has depth in one area of the stack and a proven ability to learn and contribute across new layers as product and platform needs to evolve. 

You will work on systems used in real-world environments with intermittent connectivity, shared devices, and high expectations for data integrity. Success in this role requires strong engineering judgment, curiosity, and a commitment to building reliable, maintainable software that directly supports families, caregivers, and community leaders. This is an individual contributor role with meaningful ownership and long-term impact. 

Your Responsibilities Include 

• Own features end-to-end, from problem definition through implementation, deployment, and ongoing support 
• Design, build, and maintain backend services, including data modeling and migrations 
• Build user-facing applications across mobile and web, with an emphasis on clarity, usability, and reliability 
• Support offline-capable workflows, including local persistence on mobile devices, synchronization, retries, and conflict handling 
• Write unit, integration, and end-to-end tests; add monitoring and guardrails to protect production systems 
• Collaborate closely with program stakeholders to translate real-world needs into scalable technical solutions 
• Improve system quality and developer experience through refactoring, documentation, and tooling 
• Learn and adopt new technologies or layers of the stack as the platform evolves 

Current Technology Stack (Subject to Evolution) 

• Mobile / Frontend: Flutter, local persistence (e.g., SQLite) 
• Backend: PHP / Laravel, MySQL 
• Infrastructure: Cloud-hosted services, CI/CD pipelines, and observability tooling 

You are not expected to be an expert in every technology listed above. We value adaptability, sound engineering judgment, and a track record of learning over framework-specific mastery.

Required:

• Experience as a senior or mid-senior software engineer with end-to-end ownership of production systems 

• Demonstrated ability to learn new technologies and contribute across different layers of the stack 

• Experience contributing to mobile applications (Flutter, React Native, or native iOS/Android) 

• Exposure and passion for backend stack and database design (e.g., PHP/Laravel, Node.js/TypeScript, Python/FastAPI, Go, Java/Spring) 

• Solid understanding of API design and relational data modeling Experience building reliable systems and preventing regressions through testing and monitoring. 

• Clear communication skills and comfort collaborating across technical and non-technical teams  

Preferred: 
• Familiarity with offline-first or low-connectivity system design 
• Experience working in developing-country contexts or mission-driven organizations 

The above description is not intended to be comprehensive, but rather a focused list of priorities. Success provides the opportunity to not only build a career but also bring much-needed support and care to local children and families in crisis across the United States. Successful candidates, like all Strong Family employees, are expected to live and work consistently with Strong Family's vision, mission, and values. 

Strong Family is a subsidiary of the nonprofit organization The Global Orphan Project (GO Project). Strong Family exists to break the Orphan Cycle—a recurring pattern where poverty, abuse, and lack of resources fracture families, pushing vulnerable children into orphanages, exploitative systems, and trafficking. Rather than treating the symptoms, we focus on addressing the root causes of family breakdown with scalable solutions that bring restoration to the family level. 

Strong Family offers a competitive benefits package for full-time positions (30+ hours per week) including health, dental, vision and employer paid life insurance, retirement savings and generous PTO plan and a highly competitive, market-indexed compensation when compared to similar non-profit roles. Compensation is commensurate with relevant skills and experience.
