Senior Software Engineer (Fullstack)

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.

We’re looking for a Senior Full Stack Engineer to help evolve the platform that powers our Value Calculators; tools like TCO models, value realization frameworks, and discovery-driven sales assets that enable our customers to quantify and communicate the impact of their products.

In this role, you’ll work across our Java-based backend and React/TypeScript frontend, building scalable, high-impact features while improving system reliability, performance, and observability. You’ll play a key part in shaping a platform that translates complex data and business rules into clear, actionable insights for sales teams and customers.

As part of a fully remote, Agile team, you’ll collaborate closely with product managers, UX designers, and go-to-market stakeholders. Beyond implementation, you’ll contribute to architectural direction—designing systems that are reusable, extensible, and built to support a growing suite of value-selling tools.

What You’ll Do:

Lead the design, development, and delivery of full stack features utilizing Java/React.

Define and drive architectural decisions, identifying scaling and performance improvements, while elevating engineering best practices around reliability and observability.

Partner closely with engineers, product managers, and UX designers to define technical approaches for improvements and new features.

Troubleshoot issues across distributed systems and multiple domains, identifying root causes and driving resolution.

Participate in code reviews and contribute to technical documentation

Champion engineering quality, ensuring solutions are testable, observable, maintainable, and secure.

Mentor engineers and provide technical guidance on best practices.

Operate with rigor inside project management & operation tools: write clear specifications and scope, maintain accurate statuses, uphold component and project conventions, and ensure visibility for cross-functional stakeholders.

You’ll be successful in this role with (required):

5+ years of software engineering experience with at least 2–3 years building SaaS products.

Fullstack development skills in Java and React

AI assisted development mindset and experience leveraging tools like Claude, Codex, Co-pilot to accelerate research, requirements gathering, development, and testing.

System design experience, with a track record of building scalable, reliable, and secure architectures, and improving legacy codebases.

Collaborative mindset: you communicate clearly, value feedback, and enjoy working with product, design, and infrastructure partners.

Curiosity and problem-solving: you dig into complex systems, make them better, and balance pragmatism with long-term thinking.

Nice to have:

Experience with TypeScript and modern frontend development practices
