Senior Software Engineer

About the role

The Role We're looking for a Senior Software Engineer to join our Digital team as a core full stack builder and technical owner. You'll work alongside a close-knit team of engineers to design, build, and maintain the products and platform that power Sharetec's Digital Banking experience — serving hundreds of credit union customers and their members.

Essential Duties & Responsibilities

• Technical Leadership & System Design
• 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
• Software Development & Delivery
• 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
• Collaboration, Mentorship & Continuous Improvement
• 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
• 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

Qualifications

• Required
• 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
• Preferred
• Direct experience with C# and ASP.NET Core
• 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

Paid Benefits

Competitive salaries, medical, dental, vision, life, and disability coverage, generous Paid Time Off (PTO), paid holidays (including your birthday off!), a $1,000 employee referral program, and a 401(k) with company matching.
