Senior Full Stack Software Engineer
Job Description
Sharetec is looking for a Senior Full Stack Software Engineer to join our Digital team!
When credit union members check a balance, pay a bill, or apply for a loan from their phone, they’re counting on software that works. You’ll build those web and mobile experiences from database to UI and help shape a new Digital API layer, alongside teammates who share ideas freely, review each other’s code, and help each other grow.
At Sharetec, we put people first. Our mission is to make millions of people’s lives easier through the core banking and lending software credit unions and their members rely on.
Remote (U.S., excluding California) | Full-time, exempt | $120,000 – $150,000, plus bonus eligibility
What You’ll Do
- Build and maintain web and mobile features using React, TypeScript, Next.js, React Native, and C#/ASP.NET Core
- Collaborate on scalable system design and the architecture of our Digital API layer
- Modernize existing production software with an emphasis on reliability, maintainability, and testing
- Take part in code reviews, pairing, and documentation, and help onboard new teammates
- Work with product, QA, and engineering partners to deliver and improve member-facing features
What You’ll Bring
- 6+ years of professional software engineering experience with full stack ownership
- Strong React and TypeScript skills
- Experience shipping mobile apps to both the Apple App Store and Google Play
- Backend experience with C#, Go, TypeScript/Node.js, PHP, or a comparable technology, and a willingness to work in C#/ASP.NET Core
- Experience designing and integrating RESTful APIs, including authentication and versioning, backed by relational databases
- Comfort collaborating on a fully remote team
Nice to Have
- Hands-on React Native experience
- Next.js, Docker, and modern component libraries such as shadcn/ui, Radix UI, or MUI
- Mobile release automation, CI/CD, or app store submission workflows
- Experience modernizing existing systems or designing APIs for multi-tenant platforms
- Experience in fintech or banking (credit union experience is a big plus)
Who Will Love This Job
- Someone who finds more satisfaction in making something better than building something new, and understands why that’s harder
- Someone who believes that technology serving people’s financial lives is worth doing with real care and precision
- Someone who is energized by a company in motion, where the roadmap is growing and your contributions shape the direction
