Job description

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. Why join us? • 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 are looking for a Senior Software Engineer to build product experiences and the APIs behind them. You will turn operational data into clear visualizations and help customers configure and govern APIs and AI agents. As Gravitee expands its AI Agent Management capabilities, you will help build interfaces for configuring AI Gateways, governing MCP and agent-to-agent interactions, discovering tools and agents, and monitoring how agentic systems behave in production. This is a hands-on, full-stack role for an engineer who is comfortable moving between frontend experiences, backend APIs, data models, and technical design. What You Will Be Doing In this role, you will: • Design and deliver features end to end, from discovery and technical design through implementation, testing, release, and iteration. • Build and maintain features of Gravitee API Management across the gateway runtime, the management API, and the console, including the move to Gamma. • Work across API security (OAuth2, JWT, API keys, mTLS), rate limiting and quotas, CORS, and other policy and plugin chains that sit in the request/response flow. • Design and develop Java-based APIs and services, applying asynchronous and non-blocking design patterns (Vert.x/RxJava with backpressure) to performance-sensitive gateway code. • Build clear, responsive interfaces and data visualizations using TypeScript and Angular, including observability views over Elasticsearch/OpenSearch logs and metrics. • Help customers configure and observe Gravitee's AI-related capabilities, including AI Gateways, MCP tools and servers, agent identity, and agent-to-agent interactions. • Model and transform operational data so that complex platform behavior becomes understandable and actionable. • Own US-hours Level 3 and Level 4 escalations for APIM customers as part of the L3 pager duty rotation. • Use LLMs and AI-assisted development tools thoughtfully for prototyping, implementation, testing, debugging, and exploration, applying sound engineering judgment to validate AI-generated work. • Write meaningful automated tests and contribute to reliable delivery practices. • Collaborate with product managers, designers, engineers, and technical leaders — including the APIM team based in Europe and India — to discover effective solutions and improve them through code and design reviews. • Share what you learn and help the team make practical choices as technologies and protocols evolve Essential Skills We are looking for evidence that you can succeed in the role, whether gained through employment, open-source work, or equivalent practical experience: • 5+ years building and running production backend software, on a team that ships and supports its own product; you have personally resolved production incidents. • • Strong Java experience and experience designing maintainable REST APIs and backend services, with Maven and a reactive stack such as Vert.x/RxJava with backpressure. • Strong TypeScript and modern frontend development experience using a component-based framework (Angular preferred), including building data-rich interfaces and visualizations. • Working knowledge of API gateway and reverse-proxy architecture: request lifecycle, policy and plugin chains, entrypoints/endpoints, and sync and event-driven APIs. • API security fundamentals: OAuth2, JWT, API keys, mTLS, rate limiting and quotas, CORS. • Experience with persistent data stores such as MongoDB or relational databases, and with search/analytics technologies such as Elasticsearch or OpenSearch. • Git-based workflow, code review, and writing your own automated tests. • Hands-on experience using LLMs or AI coding assistants as part of an engineering workflow, combined with the judgment to review and improve their output. • Clear communication, collaborative problem-solving, and the ability to take an ambiguous problem through to production Desired Skills You do not need to match every item. We would be especially interested in experience with: • Experience at an API gateway, proxy, or service-mesh vendor, or on the API platform team of a large company (e.g., Kong, Google Apigee, MuleSoft, Tyk, Solo.io , Traefik, WSO2). • Kubernetes operators and CRDs; OpenAPI tooling; service mesh or Envoy experience. • Docker, Kubernetes, and cloud-native application delivery. • Model Context Protocol (MCP), Agent2Agent (A2A), tool calling, LLM proxies, or other emerging AI protocols and standards. Prior production experience is not required. • Building or operating LLM-powered applications, RAG systems, or agentic workflows — especially their security, governance, and observability needs. • Open-source software or enterprise developer platforms. Who Thrives at Gravitee Our growth is powered by people who bring passion to what they build, professionalism to how they work, and a commitment to doing things well. You will thrive here if you: • Bring energy and a constructive attitude to the team. • Adapt quickly and enjoy learning unfamiliar technologies and domains. • Take ownership, communicate clearly, and follow through with urgency. • Balance delivery speed with thoughtful engineering judgment. • Start with the customer problem and care about the quality of the experience you create. • Enjoy working in a fast-moving, collaborative, international environment. Life at Gravitee At Gravitee, we invest in humans, not just roles. You’ll get: • Salary of $160,000 • Competitive medical coverage. • Pension / 401(k) program options. • Stock options - you build it, you own it. • 25 days of holiday plus in-country national holidays. • Three mental health days and a wellness allowance. • Your birthday off. 🎉 • A professional development budget to support your growth. • A hybrid work culture with hubs across regions. • Quarterly team events and an annual company offsite. • A collaborative, international company culture. • Opportunities to grow your scope and career as Gravitee grows. At Gravitee, we believe diverse perspectives make better products and stronger teams. No employee or applicant will be treated less favorably on the grounds of sex, marital status, race, color, nationality, ethnic or national origin, disability, gender, sexual orientation, gender identity, age, pregnancy or maternity, marital or civil partner status, religion, or belief.
