Résumé du poste

Gravitee is hiring a Senior Software Engineer to help build the core of how enterprises secure, govern, and control AI agents—spanning the Agent Gateway and LLM control layer. You’ll own a slice end to end, from customer conversations to shipping features.

You'll work close to customers and code, collaborating with Product Management and Design, and you’ll influence what gets built while delivering with speed and quality.

Qualifications

• 5+ years of software engineering experience, ideally in a product-facing or full-stack role.
• Comfortable talking directly to customers and translating what you hear into a technical plan.
• Hands-on experience with AI coding assistants (Cursor, Claude Code, GitHub Copilot or similar) as part of daily work.
• Strong fundamentals in API design and distributed systems.
• A bias toward shipping and iterating over building the theoretically perfect solution.
• Familiarity with the A2A protocol or agent-to-agent communication patterns.
• Experience with API gateways or API management platforms.
• Exposure to LLM-based products or agentic workflows.
• Experience integrating multiple LLM providers into a single product surface.
• Experience with cost or usage governance for AI and LLM systems.
• Familiarity with the Model Context Protocol (MCP) or similar orchestration standards.
• Experience working in a fast-moving, ambiguous product environment.

Responsabilités

• Own a meaningful slice of the Agents or LLM control roadmap, from customer conversations through shipping and iterating on the result.
• Build features for the Agent Gateway and A2A protocol support, or for multi-LLM routing, cost control, and reliability – depending on your pod – working closely with Product Management and Design.
• Use AI-assisted development tools as a core part of your workflow to move faster from idea to shipped feature.
• Dig into usage data and customer feedback to help decide what to build next, not just how to build it.
• Prototype quickly, test with real users, and be willing to change course when something isn't landing.
• Partner with Staff Engineers and other pods where the Agents surface touches LLM control, MCP, or the core API gateway – and vice versa.

Description du poste

Gravitee is a 2025 Gartner® Magic Quadrant™ Leader, on a mission to govern the world’s intelligence.

We deliver the industry’s most advanced platform for Any API, Any Event, and Any AI Agent, trusted by global leaders like Michelin, Roche, and Blue Yonder.

• The Mission: We are the first to bridge traditional API Management with the new frontier of AI Agent Security
• The Momentum: A high-growth Leader - combining market credibility with startup speed
• The DNA: We hire people who Hold Nothing Back - passionate builders who want to redefine digital infrastructure

Don’t just watch the AI revolution. Build the infrastructure that controls and secures it.

The Role

We're looking for a Senior Software Engineer to help build the core of how enterprises secure, govern, and control AI agents – spanning the Agent Gateway that governs agent-to-agent (A2A) communication, and the LLM control layer that gives enterprises centralized command over every LLM their agents call. You'll work close to customers and close to the code, owning a slice of the Agent Gateway or LLM control roadmap end to end – depending on where your strengths and interests point. This is a role for someone who wants to own outcomes, not just tickets: you'll help decide what gets built, then build it.

What You’ll Be Doing

At Gravitee, impact isn’t abstract, it’s visible. In this role, you will:

• Own a meaningful slice of the Agents or LLM control roadmap, from customer conversations through shipping and iterating on the result.
• Build features for the Agent Gateway and A2A protocol support, or for multi-LLM routing, cost control, and reliability – depending on your pod – working closely with Product Management and Design.
• Use AI-assisted development tools as a core part of your workflow to move faster from idea to shipped feature.
• Dig into usage data and customer feedback to help decide what to build next, not just how to build it.
• Prototype quickly, test with real users, and be willing to change course when something isn't landing.
• Partner with Staff Engineers and other pods where the Agents surface touches LLM control, MCP, or the core API gateway – and vice versa.

Your impact will be visible, measurable, and felt by every enterprise trusting agents with real access to their systems, and every customer routing traffic through Gravitee's LLM control layer.

• 5+ years of software engineering experience, ideally in a product-facing or full-stack role.
• Comfortable talking directly to customers and translating what you hear into a technical plan.
• Hands-on experience with AI coding assistants (Cursor, Claude Code, GitHub Copilot or similar) as part of daily work.
• Strong fundamentals in API design and distributed systems.
• A bias toward shipping and iterating over building the theoretically perfect solution.

Desired Skills

• Familiarity with the A2A protocol or agent-to-agent communication patterns.
• Experience with API gateways or API management platforms.
• Exposure to LLM-based products or agentic workflows.
• Experience integrating multiple LLM providers into a single product surface.
• Experience with cost or usage governance for AI and LLM systems.
• Familiarity with the Model Context Protocol (MCP) or similar orchestration standards.
• Experience working in a fast-moving, ambiguous product environment.
