Qualifications

• Strong experience building modern full-stack applications with Node.js, TypeScript and React.

• Confidence using AI coding tools as part of your daily workflow while applying sound engineering judgment to architecture, code quality and technical decisions.
• The ability to thrive in ambiguity, take ownership and solve complex engineering problems in a fast-moving environment.
• Experience with developer platforms, distributed systems, infrastructure-as-code, cloud-native architectures or AI governance is a strong advantage.

• Build the core capabilities behind SoSafe's Agentic AI Platform, including agent runtimes, model routing, tool registries and shared platform services.
• Design and build production-grade platform services and developer tooling using Node.js, TypeScript, NestJS and React.
• Develop reusable AI infrastructure that enables engineering teams to build, deploy and operate AI agents securely and at scale.
• Work hands-on with LLMs, LangChain/LangGraph and agent orchestration, solving platform challenges around governance, observability and scalability.
• Own features end-to-end—from architecture and implementation through deployment and continuous improvement.
• Shape the future of AI engineering at SoSafe by contributing ideas, improving developer experience and influencing platform architecture.
