Note: The job is a remote job and is open to candidates in USA. Sharetec Systems develops core banking and lending software solutions for credit unions and their members. The Senior Software Engineer will serve as a full stack technical owner on the Digital team, designing and delivering Digital Banking products, modernizing existing systems, and architecting a new API layer. The role also includes technical leadership, code reviews, mentoring, collaboration, and maintaining reliable software delivery practices.

Responsibilities

• Partner with the Digital engineering team and leadership to design scalable, maintainable full stack systems that align with Sharetec's Digital roadmap
• Drive technical design discussions across active modernization initiatives and the new Digital API integration layer
• Evaluate and recommend tooling, patterns, and architectural decisions across the frontend (React, TypeScript, Next.js) and backend (C#, ASP.NET Core) stack
• Advocate for secure-by-default design — ensuring code is reviewed, scanned, and tested before it reaches production
• Contribute to API design standards and integration patterns that expand the reach and capabilities of Sharetec's Digital Banking platform
• Build, test, and maintain production-quality features across Sharetec’s Digital Banking web and mobile platform — including iOS and Android applications built with React Native
• Write clean, well-documented, and well-tested code across the stack — TypeScript and React on the frontend, C# and ASP.NET Core on the backend — that meets Sharetec's engineering standards
• Manage work across the full lifecycle — from design and implementation through code review, testing, and production monitoring
• Work within containerized environments using Docker and contribute to CI/CD pipeline health and reliability
• Work with relational and cloud databases including PostgreSQL and MySQL, with an understanding of when and how to apply the right data store for the job
• Deliver sprint commitments reliably, surface scope risk early, and maintain a consistent, predictable delivery cadence
• Partner closely with your Digital engineering teammates as a collaborative peer — sharing context, participating in design reviews, and proactively helping the team succeed
• Lead and contribute to code reviews that improve the quality of the codebase and help teammates grow
• Share knowledge of the Digital stack through documentation, pairing sessions, and team discussions
• Support the onboarding of future Digital team members as the team scales
• Participate actively in Agile ceremonies — planning, standups, retros — and contribute to continuous process improvement
• Invest in your own growth: stay current on the tools and patterns most relevant to the Digital stack and Sharetec's roadmap

Skills

• 5+ years of professional software engineering experience with demonstrated full stack ownership
• Strong proficiency in React and TypeScript — building and maintaining production-quality frontend applications
• Experience with Next.js or a comparable server-side rendering framework
• Experience shipping production mobile applications to the App Store (iOS) and Google Play (Android) — our mobile apps are built with React Native; candidates with native Swift or Kotlin experience are encouraged to apply as that experience transfers well
• Solid backend development experience — our stack is C# / ASP.NET Core, and candidates with backgrounds in Node.js, Go, PHP, or other strongly-typed backend languages are encouraged to apply; comfort learning and working in C# is expected
• Solid API design and integration experience — RESTful APIs with an understanding of versioning, authentication, and external service integrations
• Experience with relational databases such as PostgreSQL or MySQL in a production context — candidates with backgrounds in Redis, MongoDB, or other data stores are welcome and will find that experience translates well
• Experience with Docker and containerized development or deployment environments
• Demonstrated experience contributing to or leading the modernization of an existing production system (not just greenfield)
• Excellent communication skills and the ability to collaborate effectively in a remote-first, async environment
• Bachelor's degree in Computer Science or a related field, or equivalent professional experience
• Direct experience with C# and ASP.NET Core
• Experience with native iOS (Swift) or Android (Kotlin) development
• Familiarity with Tailwind CSS, ShadCN, or modern component libraries such as Radix UI or MUI
• Background in financial services, fintech, or banking software (credit union experience a significant plus)
• Familiarity with compliance frameworks relevant to financial software (SOC 2, PCI-DSS, etc.)
• Experience designing APIs intended for multi-tenant or platform-scale architectures
• Familiarity with Agile/Scrum workflows and experience in a distributed, remote engineering team
