About The Position

The Senior Full Stack Engineer will lead the design, development, and maintenance of internal tooling that empowers our operational teams to deliver exceptional support for our customers. Working within a small, agile team, you'll have significant ownership over the systems that keep our business running smoothly and our customers satisfied. As a senior member of the team, you'll help set technical direction, mentor other engineers, and bridge the gap between operational needs and technical solutions. The impact you'll have extends beyond code—you'll shape the tools that directly influence our team's efficiency and our customers' experience. We're looking for an enthusiastic self-starter who thrives on ownership, values collaboration deeply, and is passionate about building quality software that solves real problems for real people.

Requirements

• 5+ years of professional software engineering experience with demonstrated progression in responsibility and impact.
• Strong full-stack development skills across frontend (React, HTML, CSS, JavaScript) and backend (Node.js, .NET Core/C#, or similar).
• Deep understanding of .NET Core and modern .NET development practices.
• Familiarity with web client best practices including performance optimization, security, responsive design, and modern web standards.
• Familiarity with microservice architecture, including understanding of service boundaries, API design, inter-service communication, and distributed system patterns.
• Proven track record of designing and delivering complete features or systems from concept to production.
• Experience with SQL databases, including schema design and query optimization.
• Solid understanding of software architecture patterns, design principles, and when to apply them.
• Strong collaboration and communication skills—you can explain technical concepts clearly and work effectively with diverse stakeholders.
• Quality-focused mindset with experience implementing testing strategies and CI/CD pipelines.

Nice To Haves

• Experience building internal tooling or operational support systems.
• Understanding of message queues, event-driven architecture, and asynchronous processing patterns.
• Hands-on experience designing, implementing, or evolving microservice architectures in production environments.
• Familiarity with cloud platforms (AWS, Azure, GCP) and modern deployment practices.
• Experience with monitoring, observability, and incident response.
• History of mentoring or leading other engineers.
• Contributions to technical documentation or knowledge sharing initiatives.

Responsibilities

• Own end-to-end features for internal operational tooling, from database to user interface, making architectural decisions that balance immediate needs with long-term maintainability.
• Drive technical design for new systems and major enhancements, creating proposals that consider scalability, performance, security, and developer experience.
• Establish standards and best practices for code quality, testing, and deployment within the team.
• Anticipate and solve problems proactively, identifying technical debt, potential bottlenecks, or operational pain points before they become critical.
• Think strategically about how internal tools impact operational efficiency and customer experience, not just completing tickets.
• Champion quality through comprehensive testing strategies, thoughtful error handling, and systems that are resilient and maintainable.
• Design and implement robust, scalable full-stack solutions using modern technologies (React, Node.js, C#/.NET, or similar).
• Build intuitive, responsive UIs that operational teams want to use, applying web client best practices including performance optimization, responsive design, state management, and modern browser capabilities.
• Architect backend systems that handle operational workflows, data processing, and integrations efficiently using .NET Core and related technologies.
• Work within and contribute to microservice architectures, understanding service boundaries, inter-service communication patterns, and distributed system considerations.
• Design and optimize database queries for performance.
• Build and maintain APIs that serve both internal tools and integrations with other services.
• Write production-ready code with comprehensive testing (unit, integration, and end-to-end).
• Apply web client best practices for security (XSS prevention, CSRF protection, content security policies), performance (code splitting, lazy loading, caching strategies), and user experience.
• Design monitoring and alerting strategies to ensure system reliability.
• Lead incident response when issues arise, conducting thorough post-mortems and implementing preventive measures.
• Take ownership of mistakes, treating them as learning opportunities and ensuring the team improves from them.
• Evaluate and introduce new technologies and approaches that improve team productivity.
• Break down complex problems into manageable pieces for the team to tackle.
• Make pragmatic decisions that balance perfect solutions with shipping value to users.
• Document architectural decisions and system designs for team knowledge sharing.
