Why Us?
AI is transforming how software is built. At SoSafe, you'll join the team building the AI platform that powers the next generation of AI capabilities across our products.
Rather than building individual AI features, you'll create the shared infrastructure, tooling and services that enable every engineering team to build, deploy and operate AI safely and at scale. Working in a small, highly autonomous team, you'll have real ownership, shape technical direction, and build systems that engineers across SoSafe rely on every day.
Here's how you'll make a difference
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.
What you'll bring
Strong experience building modern full-stack applications with Node.js, TypeScript and React.
Hands-on experience building AI-powered applications or platforms using LLMs, AI agents, LangChain, LangGraph, MCP or similar technologies.
A platform mindset—you enjoy building reusable systems, APIs and tooling that help other engineers move faster.
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.
