Senior Software Engineer AI & 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.

Do you love solving tough engineering challenges and want to shape how AI is used in real products? At Mediafly , you’ll build features that help revenue teams around the world sell smarter and you’ll do it with a collaborative, remote-first team that values creativity, curiosity, and growth.

We’re looking for a Senior Fullstack Engineer with a mindset for leveraging AI to develop enterprise software. Someone who is excited to design, ship, and scale AI-powered features while also contributing across our complete tech stack which includes Python, Node.js, React, Java and C#. If you’re eager to learn, experiment, and have real impact, we want to hear from you, even if you don’t tick every box.

This role is hands-on and influential. You’ll shape architecture, experiment with new ideas, and see them through to production. The features you ship will directly improve how thousands of sales professionals close deals every day. Your contributions won’t be lost in the noise; they’ll help define what’s next.

AND you’ll have opportunities to explore leadership paths, work on greenfield AI features, and grow your expertise in AI, cloud and DevOps.

What You’ll Do:

Design and integrate AI workflows into customer-facing products using agentic architectures (e.g. MCP) and orchestration frameworks (e.g. LlamaIndex, LangChain)

Optimize LLM-powered features for performance, scalability, and cost-efficiency. This may include prompt engineering, retrieval-augmented generation (RAG), and evaluation of system quality—not necessarily model fine-tuning.

Work fullstack to build scalable, observable, and maintainable web application features.

Architect and implement APIs, databases, and cloud services to support both AI and traditional product features.

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

Mentor engineers and provide technical guidance on best practices.

You’ll be successful in this role with:
