Job description

Who we are

At Mediafly, we help the world’s top revenue teams work smarter and achieve measurable impact. Our platform brings together sales enablement, content, and performance insights so sellers have the coaching, tools, and intelligence they need to succeed. By weaving value selling into every workflow, we empower teams to accelerate deal cycles, boost win rates, and prove ROI.

For you, that means joining a company where innovation meets purpose—where your work helps businesses deliver more meaningful buyer experiences and drives results that truly matter. You’ll be part of a collaborative, growth-focused team that values expertise, creativity, and human connection.

Read this first: Research shows that while men apply to jobs when they meet an average of 60% of the criteria, women and other marginalized groups tend to only apply when they check every box. If you think you have what it takes, but don\'t necessarily meet every single point on the job description, please apply. We\'d love to have a chat to see what skills/experiences you are able to bring to this team.

We\'re seeking an experienced Senior Full Stack Engineer with strong C# and React expertise to join our remote team working on a Content Management System. You\'ll work with our C# backend and React/TypeScript frontend systems deployed on AWS. You\'ll build new features while also improving system reliability, performance, and observability. As part of our fully remote Agile team, you\'ll collaborate closely with UX designers and Product Managers to deliver exceptional solutions.

This is an individual contributor role with broad scope: you’ll influence architecture, lead through technical discovery and execution, and tackle complex engineering challenges head-on.

What You\'ll Do:

• Design and deliver fullstack web application features using React/TypeScript, C#, and AWS.
• Lead and collaborate on all portions of the SDLC including technical discovery to break down large, complex, and ambiguous problems into clear, actionable initiatives and tasks to drive successful outcomes.
• Champion quality by ensuring solutions are observable, testable, secure, and maintainable.
• Mentor teammates, share knowledge, and contribute to a culture of continuous improvement
• Collaborate with engineers, product managers, and UX designers to achieve better outcomes.
• Participate in code reviews and contribute to technical documentation.
• Help evolve our systems to meet integration and data needs.

You will be successful in this role with:

• At least 5+ years of professional software development experience particularly with C# and React. You\'ve built and maintained production-grade systems with meaningful architectural ownership.
• Hands-on experience maintaining and improving legacy systems.
• Proven ability to architect scalable, distributed systems with async data flows.
• Excellent communication and collaboration skills across technical and cross-functional partners.

The ideal candidate:

• Enjoys learning about customers\' industries and understanding how they use our products
• Love diving deep into complex systems, understanding how they work, and finding creative ways to improve them. Whether it\'s optimizing existing architecture or rethinking processes, you bring a thoughtful approach to problem-solving. You\’ve likely worked on challenging tech before and enjoy the satisfaction of making things more efficient, scalable, and future-proof.
• Finds satisfaction in solving challenging debugging problems
• Can balance technical debt reduction with feature development
• Communicates clearly and proactively with team members. Values open discussions, give and receive feedback well, and thrive in a collaborative environment
