Full job description

Edelman is a voice synonymous with trust, reimagining a future where the currency of communication is action. Our culture thrives on three promises: boldness is possibility, empathy is progress, and curiosity is momentum.

At Edelman, we understand diversity, equity, inclusion and belonging (DEIB) transform our colleagues, our company, our clients, and our communities. We are in relentless pursuit of an equitable and inspiring workplace that is respectful of all, reflects and represents the world in which we live, and fosters trust, collaboration and belonging.

Edelman’s continued evolution as the leading communications consultancy will require paramount focus on product development (technology and services) that leverages data and AI to transform its own and its client’s businesses.

You’ll collaborate with cross-functional teams to bring innovative solutions to life, leveraging modern APIs, AI models, and automation tools to push the boundaries of what’s possible. If you are passionate about backend development and excited by the evolving landscape of AI, we’d love to hear from you.

Debug, test, document, and improve applications for performance, reliability, and usability.
Collaborate with product, strategy, design, and technical teammates to move ideas from concept to shipped product.
Stay current with emerging AI development practices, tools, and application patterns.

What We’re Looking For

Curiosity and initiative to keep up with fast-moving AI and web technologies, evaluate what matters, and apply them in product work
1–3 years of software development experience, including professional, internship, freelance, or strong project-based work.
Experience building web applications with React and Python .

Interest in AI application development, LLMs, automation, and emerging developer tools.
Ability to learn quickly, troubleshoot independently, and work in a fast-moving environment.
Strong communication skills and comfort working with both technical and non-technical teammates.

Preferred Experience

Experience with OpenAI APIs or other LLM APIs.
Experience with Supabase /PostgreSQL, edge functions, or serverless backend patterns.
Experience deploying applications on Vercel , AWS , or self-hosted platforms such as Coolify .
Familiarity with Docker, environment variables, secrets management, and basic production deployment practices.
Experience using AI coding tools such as Cursor, Codex, Claude Code, GitHub Copilot , or similar.
