Senior Full Stack Software Engineer

Job Type
Full-time
Description
Sharetec is looking for a Senior Full Stack Software Engineer to join our team!
At Sharetec, we believe in a people-first business. Our mission is to make millions of people’s lives easier by developing innovative core banking and lending software solutions for credit unions and their members. Our customers rely on us for powerful financial technology that enhances operations across accounting, lending, member services, and online banking — and they count on us to be a caring, trusted partner in their success.
The Role
We’re looking for a Senior Full Stack Software Engineer to help build the software that credit unions across the country use every day. You’ll work hands-on across the full stack — backend services, data architecture, and front-end applications — to deliver software that is reliable, scalable, and easy to use.
Much of this work involves modernizing long-lived production systems into modular, maintainable designs. You’ll lead design discussions, set a high bar in code reviews, mentor mid-level and junior engineers, and work closely with product managers, QA, and DevOps to turn business needs into working software.
If you enjoy solving hard problems in production systems, like helping other engineers grow, and care about building software people depend on, this role may be for you.
Position Details
This is a full-time, exempt position. Candidates may work remotely from anywhere in the United States, with the exception of California.
The starting salary range for this position is $110,000 – $140,000 based on experience plus bonus.
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
Someone who is as comfortable in a front-end component as they are designing a database schema or a backend service
Someone who asks “why was it built this way?” before deciding how to change it
Someone who makes the engineers around them better through code reviews, pairing, and clear documentation
Someone who wants to own a product area and see their decisions show up in production
Someone who cares about secure, well-tested code — especially when it handles people’s money
Essential Duties & Responsibilities
Technical Leadership
Architect scalable, secure, and maintainable systems across backend, frontend, and database layers
Lead design discussions, code reviews, and engineering best-practice initiatives
Evaluate new technologies and guide adoption of tools that improve developer productivity and system performance
Define and document architecture patterns, design principles, and shared libraries for reuse across teams
Partner with DevOps on CI/CD pipelines, deployment automation, and observability tooling
Software Development
Build high-quality, production-ready features using modern frameworks and cloud platforms
Write clean, testable, and efficient code, and help our coding standards evolve
Optimize system performance, reduce technical debt, and improve reliability
Work with QA engineers on automated testing strategies and code coverage
Take part in the production support rotation and lead root cause analysis and prevention
Collaboration & Mentorship
Mentor and coach mid-level and junior engineers
Partner with product managers and stakeholders to translate business needs into technical solutions
Give feedback and guidance during design and implementation reviews
Act as a technical resource and subject matter expert for your product domain
Qualified Candidates Should Have
Required
6+ years of professional software development experience, including technical leadership on complex projects
Deep proficiency with at least one backend platform: C#/.NET, Java/Spring Boot, Node.js, OpenEdge, or Python/FastAPI
Advanced experience with modern frontend technologies: Angular, React, or Vue.js
Strong database design and data architecture expertise: Progress, PostgreSQL, SQL Server, or MongoDB
Experience integrating APIs and third-party systems securely and efficiently
Proven ability to modernize legacy applications into modular designs
Familiarity with DevOps tooling, CI/CD pipelines, and cloud services
Strong understanding of software architecture, design patterns, and performance optimization
Clear communication skills for explaining complex technical ideas to varied audiences
Bachelor’s degree in Computer Science, Software Engineering, or a related field (or equivalent experience)
Preferred
Experience leading small teams or serving as technical lead on a feature squad
Experience designing distributed systems or microservice architectures
Hands-on experience with containers and orchestration (Docker, Kubernetes)
Security-first mindset and experience implementing secure coding practices
Prior experience in financial services or fintech
Familiarity with SOC 2 or other compliance frameworks
