Location: Seffner, FL (5 days onsite)
Role Overview
We are seeking a Senior Full‑Stack Software Engineer to design, build, and maintain business‑critical software applications that support complex operational workflows. This role is focused on developing reliable, scalable internal systems rather than consumer‑facing marketing or simple e‑commerce applications.
The ideal candidate has strong experience across the full stack, enjoys solving real‑world business problems, and can translate complex operational requirements into maintainable, high‑quality software. You will work closely with cross‑functional stakeholders to modernize systems, introduce automation, and improve efficiency, accuracy, and decision‑making.
Key Responsibilities
- Design, develop, and maintain full‑stack applications using JavaScript with modern front‑end frameworks (Vue.js and/or React), and backend services using C# and .NET Core.
- Build and enhance business applications that support operational workflows, decision‑making, and data‑driven processes.
- Develop and maintain backend APIs, services, integrations, and core business logic.
- Create front‑end user interfaces for complex workflows involving prioritization, approvals, exception handling, reporting, and data visualization.
- Work with relational databases, including data modeling, querying, performance optimization, and application‑level data access patterns.
- Integrate software solutions with internal systems, third‑party platforms, and enterprise tools.
- Collaborate closely with engineering, product, operations, QA, and business stakeholders to gather requirements and deliver solutions.
- Translate complex business needs into scalable and maintainable technical designs.
- Participate in architecture and design discussions related to performance, security, scalability, and long‑term maintainability.
- Review code and provide constructive feedback to improve overall engineering quality.
- Mentor junior and mid‑level engineers through code reviews, pairing, and technical discussions.
- Produce and maintain technical documentation, including system diagrams, API documentation, and implementation notes.
- Troubleshoot production issues, perform root‑cause analysis, and implement long‑term fixes.
Required Qualifications
- 5+ years of professional software engineering experience.
- Proven experience as a full‑stack developer working across front‑end and backend technologies.
- Strong experience with JavaScript and modern front‑end frameworks such as Vue.js and/or React.
- Hands‑on backend development experience using C#, .NET Core, and ASP.NET Core.
- Experience building backend APIs, services, integrations, and data‑driven application logic.
- Strong understanding of relational databases, including data modeling, SQL, performance tuning, and transactional systems.
- Experience developing internal business applications, enterprise software, or operational systems.
- Solid understanding of API design, authentication, authorization, validation, logging, and secure coding practices.
- Experience working with Git‑based workflows, pull requests, and code reviews.
- Familiarity with Agile or Scrum development environments.
- Strong written and verbal communication skills, including technical documentation.
- Ability to balance engineering quality with business priorities and delivery timelines.
- Demonstrated experience mentoring other developers and contributing to team growth.
